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 .
Status of the claims
Claims 1-25 are pending.
The rejection of claim 19 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requirement (for an inadequate written description of the broad genus of plants that the claim encompasses) is withdrawn in light of Applicant’s amendment of the claim. Examiner notes that claim 19 remains rejected, however, under 35 U.S.C. 112(a), on the grounds of inadequate disclosure of breeding history.
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 1-25 remain 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. The rejection is repeated for the reasons of record as set forth in the Office action mailed 17 July 2025. Applicant' s arguments filed 27 October 2025 have been fully considered but they are not persuasive.
A. MPEP 2163 section (I) states “Compliance with the written description requirement is essentially a fact-based inquiry that will ‘necessarily vary depending on the nature of the invention claimed.’" Enzo Biochem, 323 F.3d at 963, 63 USPQ2d at 1612.” In this case, the nature of the invention claimed is the creation of a new lettuce cultivar “NUN 08237 LTL”. It is well established that a plant is defined by its phenotype (traits) and its genotype (breeding history). Applicant has not provided any information on the genotype of “NUN 08237 LTL” and thus fails to provide an adequate written description of the claimed invention. Specifically, the instant application is silent as to the breeding history used to produce the claimed plant variety.
Additionally, 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 examination, including search of the prior art, nor does it provide enough description to be sufficient to aid in the resolution of questions of infringement.
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 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” (See “Applying for a Plant Variety Certificate of Protection” by the USDA reference to Exhibit A). 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 (See UPOV EDV Explanatory 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). 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 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.
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 teaches that the assumption that elite cultivars are composed of relatively homogenous genetic pools is false. (See Haun; page 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. (See Haun; page 645, right column and page 646, left column). In addition to genetic variation, environmental variation may lead to phenotypic variation within a cultivar. (See Großkinsky; page 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 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/drawing to provide the breeding history used to develop the instant variety or cultivar. 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 variety. 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 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 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 variety). 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 Applicant’s arguments:
The Applicant’s arguments in the response submitted on 27 October 2025 have been carefully considered but they were not found to be persuasive. Applicant argues that the specification provides the physiological and morphological characteristics of the claimed variety (Remarks, page 7). Applicant argues, citing Ex Parte C, Ex Parte McGowen, and Enzo, that the written description requirement is provided by the deposit (response pg 7-9).Citing selected case law, Applicant argues that “the PTO does not cite any persuasive or binding authority for the proposition that the specification must provide the breeding history of the claimed variety” (Id., page 9).
This is not found persuasive.
The best starting point for a written description analysis is not interpretation of the patent law by courts, but the law itself. With respect to written description, the first 10 words of 35 USC § 112(a) are very important:
“The specification shall contain a written description of the invention…” (emphasis supplied).
Accordingly, the strict interpretation of the law is clear. Applicant must provide in the specification a written description. The only question is what is an “adequate written description”. This is a fact-based inquiry done by the factfinder (the USPTO examiner) when analyzing the nature of the instant invention.
In this case, 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 the 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 findings to clarify the law. They are solely to clarify the finding of fact (that is - what is an adequate written description for the instant plant variety). Applicant’s arguments essentially ask the Office to not consider the actual statute and to base the decision solely on statements from court/board cases that do not directly decide what an adequate written description is a for a plant variety.
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.
Therefore, for at least the reasons of record, and those reasons indicated above, the rejection is maintained.
