Office Action

§112 §Other
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 . Priority Acknowledgment is made of applicant’s claim for benefit under 35 U.S.C. 119(e). Status of the Claims Claims 1-12, 19-24 are pending. Claims 1-12, 19-24 are examined herein. Specification The disclosure is objected to because of the following informalities: The Specification at paragraph 98-100 lists the accession numbers under which the tomato hybrid "E15C42808" is deposited as X3 on an unspecified date. The deposit accession number is not complete and cannot be used to access the deposited seeds and the date needs to be specified. Appropriate correction is required. It is noted that the claims have been amended to recite a deposit number. 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. Claims 1-12, 19-24 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 pre-AIA the inventor(s), at the time the application was filed, had possession of the claimed invention. The Federal Circuit has clarified the written description requirement. The court stated that a written description of an invention "requires a precise definition, such as by structure, formula, [or] chemical name, of the claimed subject matter sufficient to distinguish it from other materials". University of California v. Eli Lilly and Co., 119 F.3d 1559, 1568; 43 USPQ2d 1398, 1406 (Fed. Cir. 1997). The court also concluded that "naming a type of material generally known to exist, in the absence of knowledge as to what that material consists of, is not description of that material". Id. Further, the court held that to adequately describe a claimed genus, Patent Owner must describe a representative number of the species of the claimed genus, and that one of skill in the art should be able to "visualize or recognize the identity of the members of the genus". Id. Claims 3, 8, 10 and 11 are directed to ovules or pollen from the hybrid tomato of Claim 2 and plants regenerated from said pollen or ovules. Because the tomato plant of claim 2 is a hybrid or F1 progeny of two distinct inbred tomato lines, the pollen and ovules are reasonably understood to comprise a vast variety of different individual embodiments having recombined chromosomes. Plants grown from said pollen and ovules would exhibit any number of morphological and physiological traits that would be distinct from the Claimed hybrid. There is no description of said chromosomal recombinants or plants with different traits. As such, Applicant cannot be deemed to have been in possession of the genus claimed in Claims 3, 8, 10 and 11 at the time of filing. Claims 5-7 are directed to plants having essentially all the morphological and physiological characteristics of the plant of claim 2 and derivatives thereof. There is no limitation in the claims with respect to any particular genetic makeup or parental background. The plants and derivatives of Claims 5-7 could be generated from any parental lines and breeding program and as such encompass a vast array of potential species. Applicant has described tomato hybrid E15C42808 by virtue of a description of its morphological and physiological characteristics. (Table 5 and 6). Applicant has not described the vast genus of plants and plant parts as claimed in claims 5-7. No genetic background is provided by the instant disclosure as it relates to tomato hybrid E15C42808 (see below) and no description of the genetics or breeding strategies required to produce the claimed genus of plant and parts is disclosed. The single species of tomato hybrid E15C42808 is insufficient to describe the claimed genus by virtue of example. As such, Applicant cannot be deemed to have been in possession of the genus claimed in Claims 5-7 at the time of filing. Breeding History 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 tomato hybrid E15C42808. So, the examiner will evaluate what is an adequate written description for a new soybean 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 Table 1. However, there is no accompanying breeding history in the specification. The specification states that tomato hybrid E15C42808 was developed using a cross of two proprietary lines, but it is unclear what the lines are and if the lines are or were available to the public. 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 above factual evidence 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 hybrid. 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 cultivar. If Applicant’s breeding history uses proprietary cultivar 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 variety). 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) Claims 5-7 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 enablement requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to enable one skilled in the art to which it pertains, or with which it is most nearly connected, to make and/or use the invention. Claims 5-7 are directed to any tomato plant having all, or essentially all, the physiological and morphological characteristics of the tomato plant of claim 2 (a plant grown from the seeds of the recited hybrids) (Claim 5), a plant part from the plant of claim 5, wherein said part is a leaf, an ovule, a pollen grain, a fruit, or a cell (Claim 6) and the plant part of claim 6, wherein said part is a fruit. Without the seeds of the recited hybrid varieties, one of ordinary skill in the art could not make the plants and parts claimed in Claims 5-7 (essentially identical plants) without undue trial and error experimentation. As such, Claim 5 should be amended to recite that the plants are obtained from the deposits as recited in Claim 1. Conclusion No claims are allowed.
