Office Action

§103 §112 §DP
DETAILED ACTION Claims 1-20 are pending. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . The terminal disclaimer filed on 20 August 2025 disclaiming the terminal portion of any patent granted on this application which would extend beyond the expiration date of any patents that issue from Application Nos. 18/241,110, 18/241,116, and 18/241,122 has been reviewed and is accepted. The terminal disclaimer has been recorded. The objection to the specification is withdrawn in light of Applicant’s deposit statement. The rejection of claims 18-19 under 35 U.S.C. 101 because the claimed invention is directed to a law of nature without significantly more is withdrawn in light of recent Office guidance. The rejection of claims 1-20 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the subject matter that the inventor or a joint inventor, or for pre-AIA the applicant, regards as the invention is withdrawn in light of Applicant’s deposit statement, amendment of claim 13, and disavowal of “a plant of “soybean cultivar 23020503” as reading on the definition of “soybean plant” in ¶195 and “single locus conversion” as encompassing anything other transgenes (response pg 7-8). The rejection of claims 1-20 under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the enablement requirement is withdrawn in light of Applicant’s deposit statement. Applicant is reminded that because viability testing of all deposits is required before they can be considered to meet the requirements of 37 CFR 1.801- 1.809, they are advised to perfect the deposit as early as is possible, and before the payment of the issue fee. Failure to perfect a deposit by the date of payment of the issue fee may result in abandonment of the application for failure to prosecute. Claims 1-20 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claim s 1-20 of copending Application Nos. 18/241,110, 18/241,116, and 18/241,122. Although the claims at issue are not identical, they are not patentably distinct from each other. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), first paragraph: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1-20 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter that was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for pre-AIA the inventor(s), at the time the application was filed, had possession of the claimed invention. The rejection is repeated for the reasons of record as set forth in the Office action mailed 20 May 2025. Applicant’s arguments filed 20 August 2025 have been fully considered but they are not persuasive. Part A of the previous rejection was overcome by Applicant’s overcoming the indefiniteness rejection and by amendment of claim 13. B. The instant specification fails to satisfy the written description requirement of 35 U.S. Code § 112(a) because it does not provide a description sufficient to conduct an to conduct an examination, including search of the prior art MPEP 2163 (I) states “The written description of the deposited material needs to be as complete as possible because the examination for patentability proceeds solely on the basis of the written description. See, e.g., In re Lundak, 773 F.2d 1216, 227 USPQ 90 (Fed. Cir. 1985); see also 54 Fed. Reg. at 34,880 ("As a general rule, the more information that is provided about a particular deposited biological material, the better the examiner will be able to compare the identity and characteristics of the deposited biological material with the prior art.").” The instant specification fails to satisfy the written description because it does not provide enough description to be sufficient to aid in the resolution of questions of infringement. MPEP 2163(I) states “The description must be sufficient to permit verification that the deposited biological material is in fact that disclosed. Once the patent issues, the description must be sufficient to aid in the resolution of questions of infringement." Id. at 34,880.)” (Quoting the Deposit of Biological Materials for Patent Purposes, Final Rule, 54 Fed. Reg. 34,864 (August 22, 1989) at 34,880). In the instant application, a full examination cannot be conducted. In claims 1-20, Applicant claims a new soybean cultivar, 23020503. A plant cultivar is defined by both its genetics (breeding history) and its traits. Applicant has provided a description of the plant traits as seen in the specification. While Applicant has provided the breeding history for the instantly claimed plant cultivar, the one of the parents used to produce it is not known in the art, at least under the name provided. The instant application is thus incomplete as to the breeding history used to produce the claimed plant cultivar. The criticality of a breeding history in assessing the intellectual property rights of a plant is well recognized in the field of plant breeding. With regard to Plant Patents, MPEP 1605 states that a complete detailed description of a plant includes “the origin or parentage”. Other bodies that grant intellectual property protection for plant varieties require breeding information to evaluate whether protection should be granted to new varieties. A breeding history, including information about parentage and breeding methodology, is part of the requirements of Plant Variety Protection (PVP) applications. That information is used to “determine if development is sufficient to consider the variety new” (USDA, “Applying for a Plant Variety Certificate of Protection”, https://www.ams.usda.gov/services/pvpo/application-help/apply, accessed 1 May 2023). Additionally, the International Union for the Protection of New Varieties of Plants (UPOV) considers breeding history and methodology part of its evaluation of essentially derived plant varieties (UPOV, 2017, Explanatory Notes on Essentially Derived Varieties Under the 1991 Act of the UPOV Convention, see notes 14 and 30). While the USPTO, USDA, and UPOV have different laws governing intellectual property rights, all recognize that a breeding history is an essential part of adequate description of the plant sought to be protected. The breeding history is also necessary to aid in the resolution of patent infringement by providing information necessary to determine whether differences in plants where genetic differences, differences caused by the environment, or differences within the accepted variation within a variety. Historically, the USPTO has considered breeding history information when determining the patentability of a new plant variety (See Ex Parte C (USPQ 2d 1492 (1992) and Ex Parte McGowen, Board Decision in Application 14/996,093, 2020). In both of these cases, there were many differences cited by the applicant when comparing the prior art and the new plant variety. However, because the breeding history was available, these differences were deemed to be obvious and within the natural variation expected in a backcrossing breeding process. Without a breeding history in these cases, a complete comparison with the prior art could not have been possible. Moreover, a specification devoid of a breeding history hampers the public’s ability to resolve infringement analysis with plants already in the prior art as well as plants that have not yet been patented. Because the instant specification lacks the complete breeding history, the public will not be able to fully resolve questions of infringement. Since the breeding history, including one of the parents, is not known to the public, the public could only rely on the phenotypes of the claimed plant for assessing potential infringement. As seen above in Ex Parte C and Ex Parte McGowan, a trait table is insufficient to differentiate varieties by itself. It has been long established that intracultivar heterogeneity exists in crop species. The assumption that elite cultivars are composed of relatively homogenous genetic pools is false (Haun et al, 2011, Plant Physiol. 155:645-655; see pg 645, left column). Segregation, recombination, DNA transposition, epigenetic processes, and spontaneous mutations are some of the reasons elite cultivar populations will maintain some degree of plant-to-plant variation (pg 645, right column, paragraph 2, to pg 646, left column, paragraph 3). In addition, environmental variation may lead to phenotypic variation within a cultivar. (Großkinsky et al, 2015, J. Exp. Bot. 66:5429-5440; see pg 5430 left column, paragraph 2, and right column, paragraph 2). In view of this variability, a breeding history is an essential and the least burdensome way to provide genetic information needed at adequate describe a newly developed plant. Thus, an application that does not clearly describe the breeding history does not provide an adequate written description of the invention. To overcome this rejection, Applicant must amend the specification to identify any and all other potential names for all parental lines utilized in the development of the instant cultivar. For example, if Applicant’s breeding history uses proprietary line names, Applicant should notate in the specification all other names of the proprietary lines, especially publicly disclosed or patented line information. If the breeding history encompasses a locus conversion or a backcrossing process, Applicant should clearly indicate the recurrent parent and the donor plant and specifically name the trait or transgenic event that is being donated to the recurrent parent. If either of the parents is a backcross progeny or locus converted line of a publicly disclosed line, Applicant should provide the breeding history of the parent line(s) as well (i.e., grandparents). Applicant is also reminded that they have a duty to disclose information material to patentability. Applicant should also notate the most similar plants, which should include any other plants created using similar breeding history (such as siblings of the instant cultivar). This information can be submitted in an IDS with a notation of the relevancy to the instant application or as information submitted as described in MPEP 724 (e.g., trade secret, proprietary, and Protective Order). Response to Arguments Applicant urges that in Ex Parte C, Enzo and Inari to assert that the written description requirement is provided by the deposit, such that they do have to provide a breeding history; the public can access their deposit and perform a molecular marker analysis that would provide structural (genetic) characteristics to distinguish the instant plant from other plants in the public domain (response pg 11-13). This is not found persuasive. Regarding Applicant’s argument that the public can access their deposit and perform a molecular marker analysis that would provide structural (genetic) characteristics to distinguish the instant plant with other plants, instant claims 18-19 are drawn to a method comprising detecting at least a plurality of first polymorphisms in a sample of nucleic acids from the claimed plant. So, Applicant is asking to preclude the public from performing a marker analysis that Applicant is saying the public can do to distinguish the instant plant from other plants. Applicant needs to explain how the public can conduct a marker analysis if they have claims preventing the genotyping of the plant. If the public cannot genotype the plant, they cannot do a marker analysis Applicant says is possible to do. If a marker analysis cannot be done, then Applicant’s assertion that written description can be satisfied by way of the deposit is misleading. Applicant’s claims 18 and 19 in effect would make the public an infringer to genotype the instant variety as a means to distinguish their plant from the instant variety. Note that in response to the obviousness and double patenting rejections below, Applicant did not provide a genetic marker analysis to show that the instant variety is not obvious over the cited plants. If genetic marker analysis can be used distinguish the instant variety, why didn’t Applicant provide marker information to show that the instant variety is not obvious over the plants cited in the obviousness and double patenting rejections? It is noted that Applicant is in the best position to do so as they own the prior art patent and the instant variety and likely have markers available. Applicant’s failure to provide this information is evidence that it is not practical to do a marker analysis to distinguish the instant plants as claimed from other plants with related phenotypes. Applicant has other plants with nearly identical traits. The trait similarity and the lack of explanation of the value of the instant soybean makes the analysis on the breeding history more important. MPEP 2163(I) states “The description must be sufficient to permit verification that the deposited biological material is in fact that disclosed. Once the patent issues, the description must be sufficient to aid in the resolution of questions of infringement." Id. at 34,880.)” (Quoting the Deposit of Biological Materials for Patent Purposes, Final Rule, 54 Fed. Reg. 34,864 (August 22, 1989) at 34,880). Regarding Applicants’ arguments on the legal basis of the written description rejection and the court’s/board’s interpretations. The best starting point for a written description analysis is the law itself. The first 10 words of 35 USC 112 (a) are critical. (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. (emphasis added) The strict interpretation of the law is clear: Applicant must provide in the specification a written description of the invention. The only question is what an “adequate written description” is. This is a fact-based inquiry done by the factfinder (i.e., the examiner) when analyzing the nature of the instant invention. The Office has made a finding of fact that for the instant variety the minimum description is the combination of the phenotype and genotype (breeding history). To support this finding of fact, the Office has cited other plant-related intellectual property organizations and relevant court cases dealing with plant varieties in which both the phenotype and genotype are analyzed. The Office did not cite these finding to clarify the law. They are solely to clarify the finding of fact, i.e., what is an adequate written description for the instant plant variety. Applicant’s arguments ask the Office to not consider the actual statute and base our decision solely on statements from court/board cases that do not directly decide what an adequate written description is for a plant variety. In the obviousness and double patenting rejections below, the Office provided an example of another soybean plant that has a phenotype makes obvious a soybean plant with the phenotype of the instant variety. This plant is owned by Applicant. Because of the phenotypic similarity, the Office needs to analyze the genotype of the claimed plant more carefully. A review of the genotype only provided for one of the parents arbitrary/proprietary line information that is not useful to someone that is not the Applicant. This line name does not allow for the Office to have a full understanding of the instant variety. In response to the 103 rejection below, Applicant argued that the claimed plant has a unique combination of chromosomes produced by making a specific cross. However, Applicant provided no evidence that the chromosome combinations in 23020503 are not a species of genus of chromosome combinations produced when backcrossing rhg4 into the prior art plant. Applicant has provided no evidence whatsoever regarding the chromosome combination in 23020503. Applicant didn’t even provide evidence that the parental lines of the instant variety are genotypically distinct from the lines cited in the rejections. The references cited in the rejection are evidence regarding that question of fact regarding what is considered when describing plants. They are not cited for legal analysis. The references cited, including USDA and UPOV, establish that in the plant variety art, a breeding history is part of the description of a plant variety. Applicant has not provided evidence saying that in the plant variety art the breeding history is not considered art of the description of a plant variety. Applicant has not rebutted the evidence provided in the rejection. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 1-20 are rejected under 35 U.S.C. 103(a) as being unpatentable over Mason (2021, US 11,006,607) in view of Meksem et al (US 2020/0270628). The rejection is repeated for the reasons of record as set forth in the Office action mailed 20 May 202. Applicant’s arguments and the Mason Declaration, both filed 20 August 2025, have been fully considered but they are not persuasive. The claims are drawn to soybean cultivar 23020503, methods of using it, and products produced therefrom. Mason teaches soybean cultivar 15EN312435-26, which is also known as 23020503 (column 6, lines 46-47). Like the instantly claimed cultivar, 15EN312435-26 has purple flowers, buff hila, grey pubescence, tan pod walls, yellow seed coat color, dull seed coat luster, yellow cotyledons, ovate leaflets, indeterminate growth habit, the rhg1 soybean cyst nematode resistance gene, and the DAS-44406-6 event (Table 1 and the two paragraphs immediately following). The instant soybean and 15EN312435-26 have similar values for relative maturity, lodging, height, seeds/lb, seed protein % and seed oil %. Mason does not teach 15EN312435-26 with the rhg4 soybean cyst nematode resistance gene. Meksem et al teach that soybean plants with both the rhg1 and rhg4 soybean cyst nematode resistance genes have strong resistance to soybean cyst nematode (¶206) and teaches several sources of this gene (Figures 3 and 4B). Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art to modify 15EN312435-26 taught by Mason to introgress in the rhg4 soybean cyst nematode resistance gene described in Meksem et al. One of ordinary skill in the art would have been motivated to do so because Meksem et al teach that soybean plants with both the rhg1 and rhg4 soybean cyst nematode resistance genes have strong resistance to soybean cyst nematode (¶206) and because Mason suggests adding a soybean cyst nematode resistance gene to 15EN312435-26 (column 14, lines 16-18; column 16, lines 26-30). The rhg4 gene would be a nontransgenic way to achieve the desired soybean cyst nematode resistance. One of ordinary skill in the art would use Mason’s teaching of how to introgress a single gene into a soybean cultivar (column 24, line 36, to column 27, line 15) to introgress rhg4 into 15EN312435-26. The resulting plants would encompass those plants like the instantly claimed soybean cultivar. The claims in Mason are identical to the instant claims except for the name of the variety. It would have been obvious to one of ordinary skill in the art to apply those same methods to and produce the same products from the plant produced by introgressing rhg4 into 15EN312435-26, as these are all routine methods performed with soybean cultivars and routine products produced from them. Response to Arguments Applicant urges and the Declaration states that a head-to-head analyses for various traits between 23020503 and 23020503 showed statistically significant differences in relative maturity and height (response pg 13-14; Declaration ¶5-6). This is not found persuasive. The rejection is not an anticipation rejection and does not say that the two plants are identical. Applicant has not shown that any differences between 23020503 and 23020503 are not due to the rhg4 gene. The Declaration states that while soybean farmers evaluate many factors when selecting a variety for planting, relative maturity differences allow for optimized growing areas and reduced height can reduce lodging; these have real-world impacts (Declaration ¶7). This is not found persuasive. Applicant has not provided that the differences in relative maturity and height between 23020503 and 23020503 are differences in kind and not just degree. It is noted that 23020503 has a similar difference in relative maturity as its sibling claimed in 18/241,122 and a similar difference in height as its sibling claimed in 18/241,110, yet Applicant did not argue the double patenting rejections over those applications and instead filed a terminal disclaimer. Applicant urges and the Declaration states that the statistical analysis performed for this comparative trial explicitly incorporates the variation within the samples-ensuring that the results reflect not just the difference between group means, but also how much variability exists within each group (response pg 14; Declaration ¶6). This is not found persuasive. Applicant has not provided evidence that any difference in yield in 23020503 is unexpected to a significant degree over what would generally be produced by backcrossing rhg4 into a soybean variety. Applicant urges and the Declaration states that relative maturity and height are complex quantitative traits in soybean and the assumption that significant improvements to existing soybean cultivars are routine or that significant modifications to specific characteristics of interest can be readily made is neither supported in the action nor an accurate representation of soybean breeding; there would have been no expectation that introducing the resistance allele into 23020503 would yield 23020503 (response pg 14-15; Declaration ¶8). This is not found persuasive. Mason teaches that plants produced by backcrossing a single gene into 23020503 will have essentially all of the morphological and physiological characteristics of 23020503 and that variant traits are to be expected (column 24, lines 18-35). 23020503 would be amongst the genus of plants produced by backcrossing rhg4 into 23020503. Applicant urges and the Declaration states that the claimed cultivar is a result of the serendipitous combination of (1) the initial cross of 15CV351734-09 X 15EN312435-26, the selection and advancing methods applied, and the complex nature of genetic inheritance; the occurrence of the unique combination of chromosomes in 23020503 could not have been predicted and there would be no reasonable expectation that those chromosome combinations would be beneficial (response pg 15; Declaration ¶9). This is not found persuasive. It is noted that 15EN312435-26 is also known as 23020503 (Mason, column 6, lines 46-47). Applicant has provided no evidence that the chromosome combinations in 23020503 are not a species of genus of chromosome combinations produced when backcrossing rhg4 into 23020503. In fact, Applicant has provided no evidence whatsoever regarding the chromosome combination in 23020503. Thus, the argument is merely unsupported opinion. Applicant urges that to support an obviousness rejection there must be some expectation of success in arriving at the claimed invention based on the prior art and knowledge in the art. (response pg 15). This is not found persuasive. As discussed above, there is a reasonable expectation of success in backcrossing rhg4 into 23020503 to produce a genus of plants that have essentially all of the morphological and physiological characteristics of 23020503 plus rhg4. Applicant has not provided any evidence that 23020503 is unexpected to a significant degree over what would generally be produced by backcrossing rhg4 into a soybean variety. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent No. 11,006,607 in view of Meksem et al (US 2020/0270628). The rejection is repeated for the reasons of record as set forth in the Office action mailed 20 May 2025. 20 May 202. Applicant’s arguments and the Mason Declaration, both filed 20 August 2025, have been fully considered but they are not persuasive. The claims are drawn to soybean cultivar 23020503, methods of using it, and products produced therefrom. ‘607 claims soybean cultivar 15EN312435-26, which is also known as 23020503 (column 6, lines 46-47). Like the instantly claimed cultivar, 15EN312435-26 has purple flowers, buff hila, grey pubescence, tan pod walls, yellow seed coat color, dull seed coat luster, yellow cotyledons, ovate leaflets, indeterminate growth habit, the rhg1 soybean cyst nematode resistance gene, and the DAS-44406-6 event (Table 1 and the two paragraphs immediately following). The instant soybean and 15EN312435-26 have similar values for relative maturity, lodging, height, seeds/lb, seed protein % and seed oil %. ‘607 does not claim 15EN312435-26 with the rhg4 soybean cyst nematode resistance gene. Meksem et al teach that soybean plants with both the rhg1 and rhg4 soybean cyst nematode resistance genes have strong resistance to soybean cyst nematode (¶206) and teaches several sources of this gene (Figures 3 and 4B). Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art to modify 15EN312435-26 taught by Mason to introgress in the rhg4 soybean cyst nematode resistance gene described in Meksem et al. One of ordinary skill in the art would have been motivated to do so because Meksem et al teach that soybean plants with both the rhg1 and rhg4 soybean cyst nematode resistance genes have strong resistance to soybean cyst nematode (¶206). One of ordinary skill in the art would use ‘607’s claimed method of introgressing a single gene into 15EN312435-26 (claims 11-12 to introgress rhg4 into 15EN312435-26. The resulting plants would encompass those plants like the instantly claimed soybean cultivar. The claims in ‘607 are identical to the instant claims except for the name of the variety. It would have been obvious to one of ordinary skill in the art to apply those same methods to and produce the same products from the plant produced by introgressing rhg4 into 15EN312435-26, as these are all routine methods performed with soybean cultivars and routine products produced from them. Response to Arguments Applicant repeats arguments made in response to the 103 rejection above (response pg 16). This is not found persuasive for the reasons above. Further, Applicant has also not provided any evidence that 23020503 is unexpected to a significant degree over what would generally be produced by backcrossing rhg4 into a soybean variety. Conclusion No claim is allowed. THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
