Office Action

§112
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 . DETAILED ACTION 1. Claims 1-23 are pending and examined herein on the merits. Specification 2. The Deposit information is missing on page 43. Claim Objections 3. Claim 1 is objected to because claim 1 contains incomplete NCMA accession numbers. It is suggested that Applicant fill in the correct NCMA accession numbers to overcome this objection. 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. 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. 4. Claims 1-23 are 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 pre-AIA the applicant regards as the invention. In claims 1, the recitation “ATCC Accession No. X1” renders the claim indefinite. The recitation does not clearly identify the claimed maize cultivar and seed. Furthermore, the recitation does not set forth the metes and bounds of the claimed invention. Since the name “SAN ANGELO” is not known in the art, the use of said name does not carry art recognized limitations as to the specific characteristics or essential characteristics that are associated with that denomination. In addition, the name appears to be arbitrary, and the specific characteristics associated therewith could be modified, as there is no written description of the maize plant that encompasses all of its traits. This rejection can be obviated by amending the claims to recite the ATCC deposit number. In claim 5, the recitation “essentially all the physiological and morphological characteristics” renders the claim indefinite. It is unclear what is recitation encompasses as it is not known what physiological and morphological characteristics are included or excluded. The metes and bounds are not clear. Claim 21 recites plant part of claim 2. However, claim 2 is drawn to a plant rather than a plant part. The metes and bounds are not clear. 2-4, 6-20 and 22-23 are rejected for being dependent on a rejected claim. Written Description --lack of breeding history 5. Claims 1-23 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. 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). In the instant application, a full examination cannot be conducted because applicant failed to provide the breeding history for the instantly claimed Lettuce variety SAN ANGELO. Specifically, in claim 1 applicant claims a new Lettuce variety SAN ANGELO. A plant variety is defined by both its genetics (breeding history) and its traits. In the instant application, applicant has only provided a description of the plant traits as seen in the specification (see pages 44-46). The instant application is silent or incomplete as to the breeding history used to produce the claimed Lettuce variety SAN ANGELO. 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). Written Description 6. Claims 11 and 14 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. Claim 11 is drawn to a plant regenerated from tissue culturing from variety SAN ANGELO. Applicant describes the claimed variety LETTUCE VARIETY SAN ANGELO by virtue of a list of morphological and physiological characteristics (specification pages 15-17), and a deposit. The specification fails to describe the all the plant regenerated from tissue culture of lettuce variety SAN ANGELO. It is well known in the art that plant regenerated from tissue culting could exhibited morphological and physiological characteristics that are different from those of original plant. The specification fails to describe the common attributes that identify members of the genus. The specification fails to describe the structural features that distinguish the member of claimed genus of regenerated plant. Hence, Applicant has not, in fact, regenerated plant by tissue culturing using lettuce variety SAN ANGELO, and the specification fails to provide an adequate written description of the claimed invention. Claim 14 is drawn to plant part of an F1 plant which reads on an F2 seeds of SAN ANGELO. Applicant describes the claimed variety LETTUCE VARIETY SAN ANGELO by virtue of a list of morphological and physiological characteristics (specification pages 15-17), and a deposit. The specification fails to describe the structural features (genetics) of claimed F2 seed. The specification fails to describe the common attributes that identify members of the genus. The specification fails to describe the structural features that distinguish the member of claimed genus of F2 seed. Hence, Applicant has not, in fact, F2 seed developed from lettuce variety SAN ANGELO, and the specification fails to provide an adequate written description of the claimed invention. Therefore, given the lack of written description in the specification with regard to the structural and functional characteristics of the claimed compositions, Applicant does not appear to have been in possession of the claimed genus at the time this application was filed. Hence, Applicant has not, in fact, described the claimed invention within the full scope of the claims, and the specification fails to provide an adequate written description of the claimed invention. Given the claim breadth and lack of guidance as discussed above, the specification does not provide written description of the genus broadly claimed. Accordingly, one skilled in the art would not have recognized Applicants to have been in possession of the claimed invention at the time of filing. Deposit 7. Claims 1-23 are rejected under 35 U.S.C. 112, first paragraph, as containing 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. Since the seed claimed is essential to the claimed invention, it must be obtainable by a reproducible method set forth in the specification or otherwise be readily available to the public. If a seed is not so obtainable or available, a deposit thereof may satisfy the requirements of 35 U.S.C. 112. The specification does not disclose a reproducible process to obtain the exact same seed in each occurrence and it is not apparent if such a seed is readily available to the public. If the deposit of the seed is made under the terms of the Budapest Treaty, then an affidavit or declaration by the Applicant, or a statement by an attorney of record over his or her signature and registration number, stating the seed have been deposited under the Budapest Treaty and that the seed will be irrevocably, and without restriction or condition, released to the public upon the issuance of a patent would satisfy the deposit requirement made herein. A minimum deposit of 2500 seeds is considered sufficient in the ordinary case to assure availability through the period for which a deposit must be maintained. If the deposit has not been made under the Budapest Treaty, then in order to certify that the deposit meets the criteria set forth in 37 CFR 1.801-1.809, Applicant may provide assurance of compliance by an affidavit or declaration, or by a statement by an attorney of record over his or her signature and registration number showing that (a) during the pendency of the application, access to the invention will be afforded to the Commissioner upon request; (b) all restrictions upon availability to the public will be irrevocably removed upon granting of the patent; (c) the deposit will be maintained in a public depository for a period of 30 years or 5 years after the last request or for the enforceable life of the patent, whichever is longer; (d) the viability of the biological material at the time of deposit will be tested (see 37 CFR 1.807); and (e) the deposit will be replaced if it should ever become unviable. Accordingly, Applicant needs to provide a signed statement indicating compliance with 37 CFR 1.801-1.809, the ATCC Accession No. and evidence of deposit to overcome this rejection. Conclusion Claims 1-23 are rejected. The closest prior art is US Patent Number 8,476,498, which teaches inbred line Lighthouse having the same seed color, blistering, glossiness and anthocyanin distribution. However, inbred line Lighthouse exhibits distinct butt shape and disease resistance profiling.
