Maintained Claim Rejections - 35 USC § 112(b)
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
The rejection of claims 1-7, 9-10, 12-25, 27-46 under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention is maintained. The rejection has been modified in view of Applicant’s amendment of claims 1, 29 to recite ‘wherein the nutrient rich product is a nutritive-rich, safe organic fertilizer product or animal feed.’
Regarding claim 1 (claims 3-7, 9-10, 12-25 dependent thereof), 28 (claims 29-46 dependent thereof), the recitation of the amended phrase ‘nutritive-rich’ is indefinite because it is a descriptive/subjective term and it is unclear what the scope of the phrase is intended to encompass structurally and functionally. Without a specific quantitative definition as to what is encompassed in the term “rich” one of skilled cannot determine what is “nutritive-rich.” It is noted that said amendment is redundant from the previous version which already states that “the method yields a nutrient rich product.” Nevertheless, the metes and bounds upon which patent protection is sought cannot be ascertained from this phrase.
RESPONSE TO REMARKS: Beginning on p. 10 of Applicant’s remarks, Applicant contends that the rejection has been addressed by amendment. In summary, Applicant contends that claim 1 has been amended and as amended clearly defines the scope of the phrase "a nutrient rich product".
The argument is not persuasive. Examiner contends that Applicant’s amendment of claims 1 , 28 to recite ‘wherein the nutrient rich product is a nutritive-rich, safe organic fertilizer product or animal feed’ is simply redundant and does not necessitate withdrawal of the 112b rejection as Applicant has not clearly defined the recitation ‘‘nutritive-rich.’ The phrase “nutritive-rich” lacks specific contextual markers that point to a singular, unique entity. The recitation of ‘safe organic fertilizer product or animal feed’ merely limit the nutrient-rich to a fertilizer or animal feed. However, it remains unclear what Applicant means by “nutritive-rich” as “nutritive-rich” can encompass a minerals, vitamins, etc. It is suggested that Applicant define what is meant by “nutritive-rich.”
Maintained Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.
The rejection of claims 1-2, 4-7, 9-10, 12-14, 25, 27-29, 32-35 under 35 U.S.C. 102(a1) as being anticipated by Cheung et al (WO 02/070436 A2, Date Published: 12 September 2002, cited on IDS dated 1/26/2024) as evidenced by Riffo et al (2021, Journal of Fungi, cited on PTO-892 dated 1/16/2026) {herein Riffo} is maintained. The rejection has been modified in view of Applicant’s amendment to claims 1, 28 to recite ‘wherein the nutrient rich product is a nutritive-rich, safe organic fertilizer product or animal feed.’ See MPEP 2131.01 regarding multiple reference 35 USC 102 rejections.
Claims 1-2, 4-7, 9-10, 12-14, 25, 27 are drawn to a method of inhibiting pathogenic microbial growth in a biomass, comprising: contacting the biomass with a first hurdle of pathogenic microbial growth comprising: an effective amount of live non-pathogenic yeast; contacting the biomass with at least one second hurdle of pathogenic microbial growth selected from temperature, pressure, pH, water activity, electrical conductivity, redox potential, and a combination thereof; agitating the biomass to distribute the yeast within the biomass to provide a yeast-stabilized biomass slurry; adding a micro-nutrient consisting of yeast lysate residue to the yeast-stabilized biomass slurry; and maintaining aerobic conditions in the slurry to permit yeast to grow aerobically, wherein the effective amount of live non-pathogenic yeast is at least 1E4 CFU/mL of slurry, wherein the pathogenic microbial growth in the biomass is reduced compared to pathogenic microbial growth in an equivalent biomass that is not contacted with the at least one first and the at least one second hurdle of pathogenic microbial growth, and wherein the method yields a nutrient rich product, wherein the nutrient rich product is a nutritive-rich, safe organic fertilizer product or animal feed.
Claims 28-29, 32-35 are drawn to a method of inhibiting putrefaction in biomass, comprising: processing a biomass to produce a homogenized liquid slurry; contacting the homogenized liquid slurry with a first hurdle of pathogenic microbial growth comprising: an effective amount of live non-pathogenic yeast; contacting the biomass with at least one second hurdle of pathogenic microbial growth selected from temperature, pressure, pH, water activity, electrical conductivity, redox potential, and a combination thereof; agitating the homogenized liquid slurry continuously to distribute the yeast within the homogenized liquid slurry in aerobic conditions to provide a yeast-stabilized biomass slurry; adding a micro-nutrient consisting of yeast lysate residue to the yeast-stabilized biomass slurry; filtering the yeast-stabilized biomass slurry to remove macroparticles to produce a yeast-stabilized biomass slurry filtrate; and aerating the yeast-stabilized biomass slurry filtrate, wherein the effective amount of live non-pathogenic yeast is at least 1E4 CFU/mL of slurry, wherein the pathogenic microbial growth in the biomass is reduced compared to pathogenic microbial growth in an equivalent biomass that is not contacted with the at least one and the at least second hurdle of pathogenic microbial growth, and wherein the method yields a nutrient rich product, wherein the nutrient rich product is a nutritive-rich, safe organic fertilizer product or animal feed.
With respect to claims 1-2, 4-7, 10, 12-13, 14, 25, Cheung teaches a method of producing biological fertilizer compositions that comprise yeast cells and an organic substrate (abstract). Said method comprises inhibiting pathogenic microbial growth within organic material by utilizing at least seven and up to nine non-pathogenic yeast cell components (page 3, lines 29-33; page 6, lines 21-22). Generally, the yeast cell components of the invention are produced by culturing the pluralities of yeast cells under activation conditions such that the abilities of the pluralities of cells to perform the functions are activated or enhanced (page 4, lines 8-10). As such, said yeast components are live-cells with enhanced functionality. Cheung further teaches the process can be initiated by inoculating 100ml of medium with 1ml of an inoculum of the selected non-pathogenic yeast strain(s) at a cell density of 10^2-10^5 cell/ml (page 54, lines 14-15), which falls within the recited 1E4 CFU/ml limitation of claim 1. The process can be scaled up or down according to needs (page 54, lines 16). Absent evidence, otherwise, it is the Examiner’s position that a cell density of 10^2-10^5 cell/ml of S. cerevisiae, taught by Cheung, is a plurality of doses as said doses (10^2-10^5) are countable and quantifiable. In addition, it is the Examiner’s position that the ‘at least seven and up to nine non-pathogenic yeast cell components’ taught by Cheung are a ‘first hurdle’ as Cheun teaches said composition inhibits the growth of pathogenic microbes (page 6, lines 21-22). The optimal temperature is between 5°C to 45 ° C , which is 41 F to 113 F (page 19, line 31). It is noted that the recitation of ‘the temperature is at least 100F’ in claim 14 falls within the recited claimed range of ‘50F to 120°F’ in claim 13, upon which claim 14 depends. Examiner concludes that the temperature is raised from the lower level of what is claimed in claim 13 i.e., 50 degree. Furthermore, it is the Examiner’s position that the temperature range of 5°C to 45 ° C taught by Cheung is a ‘second hurdle’ as Applicant defines said temperature range within the instant application claim 13 as a ‘second hurdle.’ Furthermore, the organic material taught by Cheung may include sludge (abstract). Cheung further teaches mixing an organic substrate component, in a continuous process, with yeast cell components (page 3, lines 31-32; page 10, line 34). Absent evidence otherwise, it is the Examiner’s position that mixing of the yeast components with the organic material would necessarily create a slurry as it would be comprised of solid and liquid materials. Additionally, absence evidence otherwise, it is the Examiner’s position that the addition of the yeast components into the organic material would provide a yeast-stabilized biomass slurry since the yeast cell components maintain a balance of phosphorus components (page 3, lines 34-35), which is an indication of said yeast being metabolically active and stable. The organic material may also include manure or garbage (page 3, lines 29). Furthermore, absent evidence otherwise, it is the Examiner’s position that a homogenized liquid slurry would be produced as the mixing taught by Cheung would create a uniform, stable mixture of solid particles that are suspended evenly throughout the medium. Additionally, it is the Examiner’s position that mixing is the same as agitating continuously or periodically as mixing involved stirring and shaking which agitates the medium. Cheung further teaches that the yeast of the invention includes, but is not limited to living Saccharomyces cerevisiae (page 4, line 8 and page 7, line 13). Cheung further teaches that yeast cell components are provided by culturing a plurality of yeast cells in alternating electromagnetic fields over a period of time (page 10, lines 28-31). Evidentiary reference of Riffo is cited to demonstrate that yeast cells emitted with 1-5.9 GHz of EMF exhibited increased cellular permeability (page 9 para 1). As such, absent evidence otherwise, it is the Examiner’s position that the teaching of Cheung emitting a plurality of yeast cell components with EMF 3,000 MHz (3 GHz) would effectively rupture the cells membrane, causing the lysate to be within the slurry, thereby effectively adding the yeast lysate residue to the yeast-stabilized biomass slurry. Cheung further teaches that fermentation takes place under semi-aerobic conditions of which Examiner is interpreting to be the same as aerobic (claim 1) as both include oxygen. Macronutrients such as phosphorus and/or potassium may be added to the biomass (page 7, line 9). Additionally, it is noted that the recitation of “to produce a homogenized liquid slurry” (instant application claim 2) and “to produce a refined slurry filtrate” (instant application claim 46) is satisfied. As such, the product obtained by the combination of the teachings of the above references would inherently result in the same product as claimed. It is the Examiner’s position that since Cheung teaches the structure of a method of comprising a first hurdle (non-pathogenic yeast) and a second hurdle (temperature) for reducing pathogenic microbial growth, then a nutrient rich product would necessarily by formed as a product of the first and second hurdle in the presence of non-pathogenic yeast.
Since the art teaches the structure of the method of inhibiting pathogenic microbial growth in a biomass that yields a nutrient rich product, it is the Examiners position that the nutrient rich product would necessarily be nutritive-rich, a safe organic fertilizer product or an animal feed, as recited in the instant application claim 1.
With respect to claim 9, Cheung teaches mixing an organic substrate component with yeast cell components (page 3, lines 31-32). Absent evidence otherwise, it is the Examiner’s position that mixing an organic substrate (biomass) with yeast is the same as continuously agitating the biomass as the act of mixing the biomass with the yeast with necessarily agitate the biomass/yeast composition. Said process is continuous (page 10, line 33). Since the art teaches the structure of an effective amount of live non-pathogenic yeast in contact with a plurality of doses over time, it is the Examiners interpretation that the population of live non-pathogenic yeast would necessarily create the yeast-stabilized biomass slurry.
With respect to claim 27, Cheung teaches a method wherein pathogenic microorganisms, such as Escherichia coli, Salmonella spp., Shigella spp., and Campylobacter jejuni are used in the invention (page 2, lines 19-20).
With respect to claims 28, 32-35 Cheung teaches a method of inhibiting microbial growth within organic material by utilizing at least seven and up to nine yeast cell components (page 3, lines 29-33). It is the Examiner’s position that inhibit microbial growth within the organic material would necessarily inhibit putrefaction (rotting) as it is well-known in the art that rotting of organic material is most commonly due to microbial contamination. Cheung further teaches the organic material may include sludge (abstract). In addition, Cheung teaches mixing an organic substrate component, in a continuous process, with yeast cell components (page 3, lines 31-32; page 10, line 34). Absent evidence otherwise, it is the Examiner’s position that mixing of the yeast components with the organic material would necessarily create a slurry as it would be comprised of solid and liquid materials. Additionally, absent evidence otherwise, it is the Examiner’s position that the addition of the yeast components into the organic material would provide a yeast-stabilized biomass slurry since the yeast cell components maintain a balance of phosphorus components (page 3, lines 34-35), which is an indication of said yeast being metabolically active and stable. The organic material may also include manure or garbage (page 3, lines 29). Additionally, absent evidence otherwise, it is the Examiner’s position that a homogenized liquid slurry would be produced as the mixing taught by Cheung would create a uniform, stable mixture of solid particles that are suspended evenly throughout the medium. It is the Examiner’s position that mixing is the same as agitating continuously or periodically as mixing involved stirring and shaking which agitates the medium. Cheung further teaches that the yeast of the invention include, but are not limited to living Saccharomyces cerevisiae (page 4, line 8 and page 7, line 13). Cheung further teaches that yeast cell components are provided by culturing a plurality of yeast cells in alternating electromagnetic fields over a period of time (page 10, lines 28-31). Evidentiary reference of Riffo is cited to demonstrate that yeast cells that are subjected to 1-5.9 GHz of EMF exhibited increased cellular permeability (page 9 para 1). As such, absent evidence otherwise, it is the Examiner’s position that since Cheung teaches subjecting a plurality of yeast cell components to an EMF of 3,000 MHz (3 GHz) then said cells would necessarily rupture, causing the lysate to be within the slurry, thereby effectively adding the yeast lysate residue to the yeast-stabilized biomass slurry. Cheung further teaches that fermentation takes place under semi-aerobic conditions of which Examiner is interpreting to be the same as aerobic as both include oxygen. Macronutrients such as phosphorus and/or potassium may be added to the biomass (page 7, line 9). The optimal temperature is between 5°C to 45 ° C , which is 41 F to 113 F (page 19, line 31). Furthermore, Cheung teaches the biomass from the culture medium is filtered to remove particulate matters (page 44, lines 12-13). The yeasts are allowed to mix for about 10-20 minutes (page 63, lines 32-33). Absent evidence otherwise, it is the Examiner’s position that mixing the yeast with the sludge will necessarily aerate the biomass as the process of mixing with introduced oxygen into the mixture.
Since the art teaches the structure of the method of inhibiting pathogenic microbial growth in a biomass that yields a nutrient rich product, it is the Examiners position that the nutrient rich product would necessarily be nutritive-rich, a safe organic fertilizer product or an animal feed, as recited in the instant application claim 28.
For the reasons stated herein, the teachings of Cheung anticipate claims 1-2, 4-7, 9-10, 12-14, 25, 27-29, 32-35.
RESPONSE TO REMARKS: Beginning on p. 10 of Applicant’s remarks, Applicant contends that the rejection has been addressed by amendment. In summary, Applicant contends that the subject matter encompassed by the present claims requires a particular sequence. Applicant contends that Cheung discloses processing its yeast cell components and organic biomass separately before these components are mixed to provide the fertilizer composition. The yeast cell components of Cheung are produced by culturing the pluralities of yeast cells under activation conditions (application of electromagnetic field) such that the abilities of the yeast cells to perform the functions are activated or enhanced. See Cheung at 5.1-5.10. Cheung also discloses combining and culturing the activated yeast cells so that they form a symbiosis-like relationship whereby they can grow together without substantially relying on outside supplies of biologically available nitrogen, phosphorus, potassium, and carbon nutrients. See Cheung at 5.11. It is in the context of culturing and activating the yeast, with suitable carbohydrate source and application of electromagnetic field, respectively, that Cheung discloses contacting 100 ml of medium containing carbohydrates as substrate with 1 ml of an inoculum. See Cheung at 5.1-5.10 related to preparation of yeast component of the fertilizer. This is not equivalent to Applicant's claimed method of contacting a biomass with live non-pathogenic yeast. Applicant contends that Cheung's disclosure of aerobic growth of yeast is in context of culturing the yeast cells prior to contacting with an organic substrate. There is no disclosure in Cheung of maintaining the yeast-containing organic biomass slurry under aerobic conditions, as is required by the pending claims. Applicant contends that Cheung does not disclose maintaining the post-yeast-incorporated biomass/organic substrate mixture aerobically for continued yeast growth. Rather, Cheung teaches that after mixing the yeast component with the organic substrate the resulting mixture is conveyed to a granulizer to form granules and then dried in a two-stage drying process.
The argument is not persuasive. Examiner contends that Applicants arguments go beyond the scope of the claimed invention. Examiner contends that Applicant claims, in summary, contacting a biomass with live non-pathogenic yeast (first hurdle) and an environmental condition selected from: temperature, pressure, pH, water activity, electrical conductivity, redox potential, and a combination thereof (second hurdle) to make a biological fertilizer that comprises yeast cells and an organic substrate (abstract). Said method, taught by Cheung, inhibits pathogenic microbial growth within the organic material by utilizing at least seven and up to nine non-pathogenic yeast cell components (page 3, lines 29-33; page 6, lines 21-22). Generally, the yeast cell components of the invention are produced by culturing the pluralities of yeast cells under activation conditions such that the abilities of the pluralities of cells to perform the functions are activated or enhanced (page 4, lines 8-10). As such, said yeast components are live-cells with enhanced functionality. Furthermore, Examiner contends that Applicant has not limited the claimed method to take place in a particular sequence. Additionally, Examiner contends that Applicant’s claim language does not limit the steps of the method to what is claimed by Applicant in the instant application claims 1, 28 due to ‘comprising’ claim language.
Applicant contends that there is no disclosure in Cheung of a "liquid slurry" formed with the mixture of yeast and biomass/organic substrate, as is required by the present claims. Rather, Cheung describes that the manure, sludge, or garbage is dried to a moisture content of less than 5%. The only steps that occur following mixing of the activated yeast component of Cheung with the biomass with less than 5% of moisture content is granulation and drying. Thus, Cheung does not disclose forming "a yeast-stabilized biomass slurry", as is required by the subject matter encompassed by the present claims. Applicant contends that the pending claims require processing the biomass to produce a substantially homogenized liquid slurry before contacting it with live pathogen-suppressing yeast (Claim 2). While, Cheung appears to disclose preparing an organic substrate and mixing it with yeast, as disclosed above Cheung does not disclose processing the biomass to produce a "slurry" of any kind or a continuous addition of live pathogen-suppressing yeast to the organic substrate while simultaneously agitating the substrate to create a yeast-stabilized biomass slurry, as is required by Claim 9. It is axiomatic that a reference cannot anticipate a claim unless the reference explicitly discloses each and every element of the claim, combined in the same way as in the combination.
The argument is not persuasive. Examiner contends that Cheung teaches mixing an organic substrate component, in a continuous process, with yeast cell components (page 3, lines 31-32; page 10, line 34). Absent evidence otherwise, it is the Examiner’s position that mixing of the yeast components with the organic material would necessarily create a slurry as it would be comprised of solid and liquid materials. Examiner contends that Applicant Is not claiming the ‘slurry’ as a final product of the method. Examiner contends that Applicant is claiming a fertilizer product or animal feed as the product of the claimed method. Furthermore, Examiner contends that Applicant has not defined the water content of the ‘slurry.’ Examiner contends that missing the yeast components with the organic material would necessarily result in a slurry as recited in the instant application claim 1 with the recitation ‘agitating the biomass to distribute the yeast within the biomass to provide a yeast-stabilized biomass slurry.’

The teachings of Cheung as applied to claims 1-2, 4-7, 9-10, 12-14, 25, 27-29, 32-35 are set forth in the 102(a)(1) rejection above.
However, Cheung does not teach the method of claim 3, of crushing or grinding the biomass to provide the homogenized liquid slurry with at least 80% of biomass being particles with a diameter less than 2 mm (claim 3). Cheung does not teach the method of claim 18, wherein the at least one second hurdle comprises maintaining the yeast-stabilized biomass slurry at a pH less than 5 for at least 30 minutes (claim 18). Cheung does not teach the method of claim 19, wherein the yeast-stabilized biomass slurry is maintained at a pH of 4.2±0.5 for at least 30 minutes (claim 19). Cheung does not teach the method of claim 20, wherein maintaining the pH comprises adding one or more acids (claim 20). Cheung does not teach the method of claim 21, wherein the at least one second hurdle comprises maintaining the yeast-stabilized biomass slurry at a water activity less than 0.97 AW for at least 30 minutes (claim 21). Cheung does not teach the method of claim 22, wherein the yeast-stabilized biomass slurry is maintained at a water activity selected from less than 0.95 Aw, 90 Aw, or 85 Aw for at least 30 minutes (claim 22). Cheung does not teach the method of claim 23, wherein the at least one second hurdle comprises maintaining the yeast-stabilized biomass slurry at an electrical conductivity (EC) of 20.0±5 mS/cm for at least 30 minutes (claim 23). Cheung does not teach the method of claim 24, wherein the at least one second hurdle comprises maintaining the yeast-stabilized biomass slurry at a redox potential (Eh) selected from 0 mV to -200 mV for at least 30 minutes (claim 24). Cheung does not teach the method of claim 30, wherein the processing comprises crushing or grinding the biomass to provide homogenized liquid slurry with at least 80% of biomass particles having a diameter less than 2mm (claim 30). Cheung does not teach the method of claim 31, further comprising re-homogenizing and re-filtering the yeast-stabilized biomass slurry filtrate one or more times prior to the aerating step (claim 31). Cheung does not teach the method of claim 39, wherein the at least one second hurdle comprises further comprising maintaining the yeast-stabilized biomass slurry at a pH of less than 5 for at least 30 minutes (claim 39). Cheung does not teach the method of claim 40, wherein the pH in the yeast-stabilized biomass slurry is maintained at 4.2±0.5 for at least 30 minutes (claim 40). Cheung does not teach the method of claim 41, wherein the pH is maintained by addition of one or more acids (claim 41). Cheung does not teach the method of claim 42, wherein the at least one second hurdle comprises, further comprising maintaining the yeast-stabilized biomass slurry at a water activity less than 0.97 Aw for at least 30 minutes (claim 42). Cheung does not teach the method of claim 43, wherein the yeast-stabilized biomass slurry is maintained at water activity selected from less than 0.95 Aw, 90 Aw, or 85 Aw for at least 30 minutes (claim 43).

With respect to claim 3, Cheung teaches the biomass is ground up to powder form (page 4, lines 34-35). MPEP 2144.05 states"[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955) (MPEP 2144.05 IIA)." One of ordinary skill would desire to optimize the grinding of the biomass to produce particles with a diameter less than 2 mm depending on the particular application. It would be routine for one to arrive at a diameter less than 2 mm for the application they intend on using the biomass. Therefore, the above invention would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention.
With respect to claims 18-19, Cheung teaches a pH range of 5.5-8.5 for the biological composition (page 19, line 32). Although Cheung does not explicitly teach ‘wherein the at least one second hurdle comprises maintaining the yeast-stabilized biomass slurry at a pH less than 5 for at least 30 minutes,’ MPEP 2144.05 states"[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955) (MPEP 2144.05 IIA)." One of ordinary skill would desire to optimize the pH and time at which it is at said pH depending on the particular application. It would be routine for one to arrive at a pH and time for the application they intend on using the yeast-stabilized biomass slurry Therefore, the above invention would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention.
With respect to claim 20, it would be obvious to one of ordinary skill in that art that one would add one or more acids to maintain a low pH of the biomass as acids are routinely utilized in the art to maintain and/or lower the pH of compositions. Therefore, the above invention would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention.
With respect to claims 21-22, Cheung teaches the application of an electromagnetic field to a biomass with yeast components (page 10 lines 34-35 and page 11, lines 1-5). EM waves interact directly with water molecules, of which is the exact basis for how water activity is measured. As such, it is the Examiner’s position that the EMF applied by Cheung would necessarily result in water activity being applied to the biomass. , Although Cheung does not explicitly teach ‘wherein the at least one second hurdle comprises maintaining the yeast-stabilized biomass slurry at a water activity less than 0.97 Aw for at least 30 minutes,’ MPEP 2144.05 states"[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955) (MPEP 2144.05 IIA)." One of ordinary skill would desire to optimize the time at which the biomass is at a water activity depending on the particular application. It would be routine for one to arrive at a water activity for a period of time for the application they intend on using the yeast-stabilized biomass slurry. Therefore, the above invention would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention.
With respect to claim 23, Cheung teaches the application of an electromagnetic field to a biomass with yeast components (page 10 lines 34-35 and page 11, lines 1-5). Since the electrical conductivity and electromagnetic (EM) waves are directly related as the conductivity of a material dictates how it interacts with, absorbs, or reflects EM wave, it is the Examiner’s position that the yeast-stabilized biomass slurry would necessarily exhibit an electrical conductivity (EC) . Regarding the recitation ‘an electrical conductivity (EC) of 20.0±5 mS/cm for at least 30 minutes,’ MPEP 2144.05 states"[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955) (MPEP 2144.05 IIA)." One of ordinary skill would desire to optimize the time at which the electroconductivity is applied to the yeast-stabilized biomass slurry depending on the particular application. It would be routine for one to arrive at the electrical conductivity and time at which it is applied for the application they intend on using the yeast-stabilized biomass slurry. Therefore, the above invention would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention.
With respect to claim 24, Cheung teaches the application of an electromagnetic field to a biomass with yeast components (page 10 lines 34-35 and page 11, lines 1-5). Redox potential and electromagnetic waves are inherently connected because both are deeply rooted in the behavior of electrons and electric fields. As such, it is the Examiner’s position that the yeast biomass taught by Cheung would necessarily have a redox potential. Although Cheung does not explicitly teach ‘wherein the at least one second hurdle comprises maintaining the yeast-stabilized biomass slurry at a redox potential (Eh) selected from 0 mV to -200 mV for at least 30 minutes,’ MPEP 2144.05 states"[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955) (MPEP 2144.05 IIA)." One of ordinary skill would desire to optimize the time at which the biomass is at a redox potential depending on the particular application. It would be routine for one to arrive at a redox potential for a period of time for the application they intend on using the yeast-stabilized biomass slurry. Therefore, the above invention would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention.
With respect to claim 30, Cheung teaches the biomass is ground up to powder form (page 4, lines 34-35). It is obvious to one of ordinary skill in the art that the grinding of the biomass into powder, as taught by Cheung, would necessarily result in a homogenized liquid slurry since the biomass is comprised of liquid media along with the powder biomass. MPEP 2144.05 states"[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955) (MPEP 2144.05 IIA)." One of ordinary skill would desire to optimize the grinding of the biomass to produce particles with a diameter less than 2 mm depending on the particular application.

Therefore, the above invention would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention.
With respect to claim 31, one of ordinary skill in the art would desire to re-homogenize and re- to improve consistency, efficiency, and product quality filter the yeast-stabilized biomass slurry filtrate one or more times prior to aerating to improve the consistency, efficiency, and production quality. Said process is well-known in the art and routinely performed on compositions containing particulate matter to remove artifacts. Therefore, the above invention would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention.
With respect to claims 39-40, Cheung teaches a pH range of 5.5 to 8.5 for the biological composition (page 19, line 32). Although Cheung does not explicitly ‘wherein the at least one second hurdle comprises maintaining the yeast-stabilized biomass slurry at a pH less than 5 for at least 30 minutes,’ MPEP 2144.05 states"[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation."

It would be routine for one to arrive at a water activity for a period of time for the application they intend on using the yeast-stabilized biomass slurry. Therefore, the above invention would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention.
With respect to claim 44, Cheung teaches the application of an electromagnetic field to a biomass with yeast components (page 10 lines 34-35 and page 11, lines 1-5). EMF generates electrical conductivity through electromagnetic induction. As such, it is the Examiner’s position that the EMF applied by Cheung would necessarily generate electrical conductivity as the EMF generates electrical conductivity through electromagnetic induction.

As such, one of ordinary skill in the art would have a reasonable expectation that the product obtained after re-homogenization and refiltering the biomass would be freer of particulate matter that could negatively impact the performance of the product. Additionally, although Cheung does not explicitly teach ‘at a temperature of 75°F to 90°F for at least 6 hours,’ MPEP 2144.05 states"[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955) (MPEP 2144.05 IIA)."

RESPONSE TO REMARKS: Beginning on p. 16 of Applicant’s remarks, Applicant contends that the rejection has been addressed by amendment. In summary, Applicant contends that Cheung does not teach or suggest contacting the biomass with a first hurdle of pathogenic microbial growth comprising: an effective amount of live non-pathogenic yeast; contacting the biomass with at least one second hurdle of pathogenic microbial growth selected from temperature, pressure, pH, water activity, electrical conductivity, redox potential, and a combination thereof; agitating the biomass to distribute the yeast within the biomass to provide a yeast-stabilized biomass slurry; adding a micro-nutrient consisting of yeast lysate residue to the yeast-stabilized biomass slurry; and maintaining aerobic conditions in the slurry to permit yeast to grow aerobically, as is required by independent Claims 1 and 28.
The argument is not persuasive. Examiner contends that Cheung teaches a method of producing biological fertilizer compositions that comprise organic substrate and non-pathogenic yeast cells comprised of an effective amount of pathogenic microbes that inhibit microbial growth within the organic material (abstract, page 3, lines 29-33; page 6, lines 21-22; page 54, lines 14-15) as a first hurdle. The optimal temperature of the biological fertilizer is between 5°C to 45 ° C , which is 41 F to 113 F (page 19, line 31), which is a second hurdle.
The claims 15-17, 36-38 under 35 U.S.C. 103 as being unpatentable over Cheung et al (WO 02/070436 A2, Date Published: 12 September 2002, cited on IDS dated 1/26/2024) as applied to claims 1-2, 4-7, 9-10, 12-14, 25, 27-29, 32-35 in view of Ikegger (2018, Pressure fermentation, cited on PTO-892 dated 1/16/2026) {herein Ikegger} as evidenced by Riffo et al (2021, Journal of Fungi, cited on PTO-892 dated 1/16/2026) {herein Riffo} is maintained.
Claim 15 is drawn to the method, wherein the at least one second hurdle comprises maintaining the yeast-stabilized biomass slurry under a pressure of at least 2 bars for at least 30 seconds.
Claims 16 is drawn to the method, wherein with mixing the pressure is applied to each portion of the yeast-stabilized biomass slurry for at least 30 seconds.
Claims 17 is drawn to the method, wherein the pressure is maintained within the yeast-stabilized biomass slurry at a pressure selected from 5 bars to 16 bars for at least 30 minutes.
Claims 36 is drawn to the method, wherein the at least one second hurdle comprises maintaining the yeast-stabilized biomass slurry under a pressure of at least 2 bars for at least 30 seconds.
Claims 37 is drawn to the method, wherein with mixing the pressure is applied to each portion of the yeast-stabilized biomass slurry for at least 30 seconds.
Claim 38 is drawn to the method, wherein the pressure is maintained within the yeast-stabilized biomass slurry at a pressure selected from 5 bars to 16 bars for at least 30 minutes.
The teachings of Cheung as applied to claims 1-2, 4-7, 9-10, 12-14, 25, 27-29, 32-35 are set forth in the 102a1 rejection above.
However, Cheung does not teach the method of claim 15, wherein the at least one second hurdle comprises maintaining the yeast-stabilized biomass slurry under a pressure of at least 2 bars for at least 30 seconds (claim 15). Cheung does not teach the method of claim 16, wherein with mixing the pressure is applied to each portion of the yeast-stabilized biomass slurry for at least 30 seconds (claim 16). Cheung does not teach the method of claim 17, wherein the pressure is maintained within the yeast-stabilized biomass slurry at a pressure selected from 5 bars to 16 bars for at least 30 minutes (claim 17). Cheung does not teach the method of claim 36, wherein the at least one second hurdle comprises maintaining at least a portion of the yeast-stabilized biomass slurry under a pressure of at least 2 bars for at least 30 seconds. Cheung does not teach the method of claim 37, wherein with mixing the pressure is applied to each portion of the yeast-stabilized biomass slurry for at least 30 seconds (claim 37). Cheung does not teach the method of claim 38, wherein the pressure is maintained within the yeast-stabilized biomass slurry at a pressure selected from 5 bars to 16 bars for at least 30 minutes (claim 38).
With respect to claims 15-16, Ikegger teaches a method wherein the pressure is utilized at 2.5 bars in the process of fermentation to inhibit air from contacting the fermentation broth (page 2, para 4; page 6, para 2). It would be obvious to one of ordinary skill in the art to split the yeast-stabilized biomass slurry into portions and apply pressure to each portion to optimize conditions for different stages and microorganisms, prevent contamination, and manage the process efficiently. Although Ikegger does not explicitly teach ‘wherein the at least one second hurdle comprises maintaining the yeast-stabilized biomass slurry under a pressure of at least 2 bars for at least 30 seconds,’ MPEP 2144.05 states"[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955) (MPEP 2144.05 IIA)." One of ordinary skill would desire to optimize the time at which the biomass is under pressure depending on the particular application. It would be routine for one to arrive at a pressure for a period of time for the application they intend on using the yeast-stabilized biomass slurry. Therefore, the above invention would have been prima facie obvious.
With respect to claims 36-38, Ikegger teaches a method wherein pressure is utilized at 2.5 bars in the process of fermentation to inhibit air from contacting the fermentation broth (page 2, para 4; page 6, para 2). Furthermore, it would be obvious to one of ordinary skill in the art to split the yeast-stabilized biomass slurry into portions and apply pressure to each portion to optimize conditions for different stages and microorganisms, prevent contamination, and manage the process efficiently. Although Cheung does not explicitly teach ‘wherein the at least one second hurdle comprises maintaining the yeast-stabilized biomass slurry under a pressure of at least 2 bars for at least 30 seconds,’ (claim 36) and ‘a pressure selected from 5 bars to 16 bars for at least 30 minutes’ (claim 38) MPEP 2144.05 states"[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955) (MPEP 2144.05 IIA)." One of ordinary skill would desire to optimize the time at which the biomass is under pressure depending on the particular application. It would be routine for one to arrive at a pressure for a period of time for the application they intend on using the yeast-stabilized biomass slurry. Therefore, the above invention would have been prima facie obvious.
Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art to apply the teachings of Cheung et al. of a method of inhibiting microbial growth within organic material by utilizing yeast cell components (page 3, lines 29-33) or combine the teachings of Ikegger because Ikegger teaches a method wherein pressure is utilized in the process of fermentation to inhibit air from contacting the fermentation broth (page 2, para 4).
One of ordinary skill in the art would be motivated to either use the teachings of Cheung et al. by itself or combine the teachings of Ikegger because Ikegger provides the motivation for Cheung to use pressure during the fermentation process because the application of pressure reduces the amount of air that comes into contact with the fermentation mixtures (Ikegger: page 2, para 2), thereby reducing the likelihood of extraneous microbial contamination and spoilage. Additionally, the application of pressure reduces the build-up of esters which reduces the production of undesirable, overpowering flavors and aromas (page 2, para 6) for a biological fertilizer as said aromas could attract unwanted pests resulting in contamination of the biomass. One of ordinary skill in the art would have a reasonable expectation of success to try applying pressure to the fermentation mixture as doing so would reduce the likelihood of extraneous microbial contamination and spoilage.
One of skill in the art would have a reasonable expectation of success to make and use the claimed method of inhibiting pathogenic microbial growth in a biomass because Cheung provides the basic method and its uses of making it. Reference of Ikegger provides a method wherein pressure is utilized in the process of fermentation to inhibit air from contacting the fermentation broth (page 1, para 4). Therefore, there would be a reasonable expectation of success to arrive at the above invention. Therefore, the above invention would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention.
RESPONSE TO REMARKS: Beginning on p. 16 of Applicant’s remarks, Applicant contends that the rejection has been addressed by amendment. In summary, Applicant contends that Ikegger does not teach or suggest a method of inhibiting pathogenic microbial growth in a biomass, or inhibiting putrefaction in biomass, as required by Claims 1 and 28, respectively, which comprises inter alia, contacting the biomass with a first hurdle of pathogenic microbial growth comprising an effective amount of live non-pathogenic yeast, wherein the effective amount of live non-pathogenic yeast is at least lE4 CFU/mL of slurry; contacting the biomass with at least one second hurdle of pathogenic microbial growth selected from temperature, pressure, pH, water activity, electrical conductivity, redox potential, and a combination thereof; agitating the biomass to distribute the yeast within the biomass to provide a yeast-stabilized biomass slurry; adding a micro-nutrient consisting of yeast lysate residue to the yeast-stabilized biomass slurry; and maintaining aerobic conditions in the slurry to permit yeast to grow aerobically.
The argument is not persuasive. Examiner contends that the secondary reference of Ikegger teaches a method wherein pressure is utilized at 2.5 bars in the process of fermentation to inhibit air from contacting the fermentation broth (page 2, para 4; page 6, para 2). Ikegger provides the motivation for Cheung to use pressure during the fermentation process because the application of pressure reduces the amount of air that comes into contact with the fermentation mixtures (Ikegger: page 2, para 2), thereby reducing the likelihood of extraneous microbial contamination and spoilage. Whereas the primary reference of Cheung in summary encompasses a method of inhibiting pathogenic microbial growth in a biomass and all of the limitations of independent Claims 1 and 28.
