Office Action

§112
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claims 1-16 are pending and examined on their merit herein. Claim Objections Claim 13 is objected to because of the following informalities: claim number for claim 13 appears to be missing due to assumed typographic error. Appropriate correction is required. Claim Rejections - 35 USC § 112 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. Claim 15 is rejected 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. In claim 15, the term “essentially all” renders the claim indefinite. The claim is drawn to a plant produced by the method of claim 14, wherein the plant comprises a single locus conversion and otherwise comprises essentially all of the morphological characteristics of the recited variety. The Specification does not define the term “essentially all” and one of ordinary skill in the art would be advised of its metes and bounds. The term “essentially” is a relative term of approximation and requires specific guidance as to its metes and bounds to be definite. In this case, the specification supplies no guidance or definition such that one of ordinary skill in the art would be able to determine which of the characteristics of the claimed variety CL2041574, including those recited in Tables 1 and 2, must be retained for a plant to be deemed to have “essentially all” of the characteristics of said variety. The instant scenario is in contrast to that in In re Marosi, where the phrase "a silicon dioxide source that is essentially free of alkali metal" was held to be definite because the specification contained guidelines and examples that were considered sufficient to enable a person of ordinary skill in the art to draw a line between unavoidable impurities in starting materials and essential ingredients. In re Marosi, 710 F.2d 799, 218 USPQ 289 (CCPA 1983); discussed in MPEP 2173.05(b). Therefore, it is unclear which physiological and morphological characteristics the plant of claim 15 would possess. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph 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 the first paragraph of pre-AIA 35 U.S.C. 112: 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. Written Description Claims 3-4 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 which 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 applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Claims 3-4 are drawn to a soybean plant obtained by transforming the soybean plant of claim 1 and a seed of the soybean plant. Applicant does not describe the genus of soybean plants produced by genetic transformation of soybean variety CL2041574. The Specification permits any number of transgenes that may confer any number of morphological and/or physiological characteristics to the claimed plant. Applicant has failed to describe said genus. It is well known in the art that genetic transformation and transgene could have pleiotropic effects on the development, morphology, or agronomic performance of the plant. For example, Latham (J Biomed Biotechnol. 2006: 25376.) teaches that transgene insertion is infrequently, if ever, a precise event. Mutations found at transgene insertion sites include deletions and rearrangements of host chromosomal DNA and introduction of superfluous DNA. Insertion sites introduced using Agrobacterium tumefaciens tend to have simpler structures but can be associated with extensive chromosomal rearrangements, while those of particle bombardment appear invariably to be associated with deletion and extensive scrambling of inserted and chromosomal DNA. Ancillary procedures associated with plant transformation, including tissue culture and infection with A tumefaciens, can also introduce mutations. These genome-wide mutations can number from hundreds to many thousands per diploid genome. (Abstract) See Vas-Cath Inc. v. Mahurkar 1991 (CA FC) 19 USPQ2d 1111, 1115, which teaches that the purpose of the written description is for the purpose of warning an innocent purchaser, or other person using a machine, of his infringement of the patent; and at the same time, of taking from the inventor the means of practicing upon the credulity or the fears of other persons, by pretending that his invention is more than what it really is, or different from its ostensible objects, that the patentee is required to distinguish his invention in his specification. In this case, there is no way that a practitioner would be able to determine if any particular soybean plant is infringing the instant claims, and therefore, the public has not been put on notice with a sufficient description of the claimed invention. The claims are thus a “reach through” claim in which the Applicant has described a starting material and at least one method step, but has not described the resulting product; and wherein the genus of products that can be produced by the recited method steps and materials is so large that one of skill in the art is not able to envision the members of the genus. (See Univ. of Rochester v. G.D. Searle & Co., 358 F.3d 916, 920-23, 69 USPQ2d 1886, 1890-93 (Fed. Cir. 2004)). Accordingly, the specification fails to provide adequate written description to support the genus of plants produced by introducing any number of transgenes into the claimed variety. Written Description Requirement regarding Breeding History Claims 1-16 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 which 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 applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. 35 USC 112 (a) states that “The specification shall contain a written description of the invention”. In evaluating written description, the threshold question is what is “an adequate written description”. This is question of fact that is evaluated by the factfinder (examiner). MPEP 2163.04 clearly states that “The inquiry into whether the description requirement is met must be determined on a case-by-case basis and is a question of fact. In re Wertheim, 541 F.2d 257, 262, 191 USPQ 90, 96 (CCPA 1976).” The instant invention is a new soybean variety CL2041574. So, the examiner will evaluate what is an adequate written description for a new cucumber variety. In reviewing this question of fact, the examiner analyzed how plant varieties are evaluated in the public domain. The review concluded that generally the minimum requirements for an adequate description of a new plant variety has a trait table and genetic information (via a breeding history). In reviewing applicant’s specification there is a phenotypic description as is seen in, e.g., Table 5 and Table 26. However, there is no accompanying breeding history in the specification. Because the specification lacks a breeding history and that breeding history is part of the minimum description of a plant variety the applicant has not fulfilled the requirement of 35 USC 112(a) to provide a written description in the specification. The office’s reasonable basis for challenging the adequacy of written description is informed by a review of the following: With regard to Plant Patents, MPEP 1605 states that a complete detailed description of a plant includes “the origin or parentage”. 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” (See “Applying for a Plant Variety Certificate of Protection”, USDA, https://www.ams.usda.gov/services/pv po/application-help/apply, downloaded 05/01/2023, (U)). 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, Explanatory Notes on Essentially Derived Varieties Under the 1991 Act of the UPOV Convention, April 6, 2017, See UPOV EDV Explanatory Notes 14 and 30 (V)). 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) (W) and Ex Parte McGowen Board Decision in Application 14/996,093, decided June 15, 2020 (X)). 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. 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. Haun et al. (Plant Physiology, Feb. 2011, Vol. 155, pp. 645-655 (Y)) teaches that the assumption that elite cultivars are composed of relatively homogenous genetic pools is false. (p. 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 (p. 645, right column and p. 646, left column). In addition to genetic variation, environmental variation may lead to phenotypic variation within a cultivar. (Großkinsky et al., J. Exp. Bot., Vol. 66, No. 11, pp. 5429-5440, 2015 (Z), p. 5430, left column, 1st full paragraph, and right column, 2nd full paragraph). In view of this variability, a breeding history is an essential and the least burdensome way to provide genetic information needed to adequately describe a newly developed plant. The factual evidence above provides a reasonable basis that a breeding history is necessary written description. With this information the examiner has met the initial burden of presenting by a preponderance of evidence why a person of ordinary skill in the art would not recognize in an applicant’s disclosure a description of the invention defined by the claims. (See MPEP 2163.04). Please note, the citations above are not for legal authority, the legal authority relied upon by the examiner is the 35 USC 112(a) statute. The citations are presented to support the finding of fact that a breeding history is necessary to the adequate description of a plant. Although not directly relied upon for the above written description position, a complete written description additionally helps drive examination and help with infringement verification. 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.").” 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). The breeding history aids in the resolution of patent infringement by providing information necessary to determine whether differences in the plants are genetic differences, differences caused by the environment, or differences within the accepted variation within a variety. Moreover, a specification devoid of a complete 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 the parents, is not known to the public, the public could only rely on the phenotypes of the claimed plants for assessing potential infringement. 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/drawing to provide the breeding history used to develop the instant variety. When identifying the breeding history, Applicant should identify any and all other potential names for all parental lines utilized in the development of the instant cultivar and all other potential names for the claimed variety. If Applicant’s breeding history uses proprietary variety names, Applicant should notate in the specification all other names of the proprietary cultivars, especially publicly disclosed or patented cultivar 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 one 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 as well (i.e., grandparents). Applicant should identify the breeding method used, such as single seed descent, bulk method, backcross method, etc., and the filial generation in which the instant plant was chosen. Information pertaining to the homozygosity or heterozygosity of the parents as well as the instant plant should be set forth. Applicant is 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). If there any patent applications or patents in which sibs or parents of the instant plant are claimed, the serial numbers and names of the sibs or parents should be disclosed. 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). Conclusion No claims are allowed. Claims 1-16 are deemed to be provisionally free of the prior art, given the failure of the prior art to teach or suggesting a lettuce plant having all of the morphological and physiological characteristics of the deposited variety. It should be noted that this statement is based only on a comparison of the morphological and physiological characteristics of the deposit against the prior art. This is statement is provisional because Applicant has not provided any information regarding the parental lineage or breeding methodology used to produce the deposited plant variety. Without this information, a meaningful comparison of the genetic and phenotypic basis that would distinguish the deposited lettuce variety from prior art plants cannot be made. Thus, this statement will remain provisional until the necessary information is made to the Specification, and a complete search of the prior art is can be completed. The closest prior art is Delheimer (US 11064669 B2) which teaches soybean Cultivar CW1660188, which shares many traits in common (or does not significantly differ) with instant plant including: plant type, a phenotype set of “PLBBr”, (see Table 9). However, the plants differ in at least: relative maturity, transgenic events, and genetic makeup.
