Office Action

§101 §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 . Claim Status Claims 1-32 are pending and examined. Specification The specification is objected to for failing to provide the ATCC deposit information and deposit date. Appropriate action is advised. 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. Claims 1-32 are rejected under 35 U.S.C. 112(b), as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, regards as the invention. Claims 1, 3, 5, 9, 21, 23 and 24 recite incomplete accession numbers and recite the limitation inbred corn line designated “KW7ER1836” which is an arbitrary term that is not recognized in the art rendering the metes and bounds of the claim indefinite as it is not known what is or is not encompassed by the claims. Claims 2, 4, 6-8, 10-20, 22 and 25-32 are rejected for depending upon a base claim and for failing to remedy the issues of indefiniteness. 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. Claims 1-32 are rejected under 35 U.S.C. 112(a), as failing to comply with the enablement requirement. The claims contain 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 and/or plant 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, or seed of the claimed plant 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 625 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. Applicant has NOT indicated that Applicant intends to deposit the seeds at the ATCC in accordance with 37 CFR 1.801-1.809. Accordingly, Applicant needs to provide a signed statement indicating compliance with 37 CFR 1.801-1.809 indicating that all restrictions will be irrevocably be removed upon issuance of a patent, the ATCC Accession No. and evidence of deposit to overcome this rejection. 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. Claims 1-32 are rejected under 35 U.S.C. 112(a) as failing to comply with the written description requirement. The claims contain 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, at the time the application was filed, had possession of the claimed invention. Instant claims 12-17, 20, 26 and 28 a corn plant produced from seed of the corn line designated KW7ER1836 and further comprising a transgene or one or more desired traits. However, the plants produced by these methods are not required to retain any of the morphological or physiological characteristics or traits of inbred corn line KW7ER1836 while the specification only describes corn line KW7ER1836 by describing traits listed in instant Table 1. Here, the specification does not describe transforming KW7ER1836 with any transgenes and does not describe the traits retained by the plants produced by the claimed methods. Thus, the claims read on a vast genus of corn lines with varying traits for which the specification has failed to describe. Therefore, the skilled practitioner would not be led to believe Applicant was in possession of the genus of plants as broadly claimed. Regarding the lack of a breeding history in the instant specification, MPEP 2402 provides that every patent must contain a written description of the invention sufficient to enable a person skilled in the art to which the invention pertains to make and use the invention. Where the invention involves a biological material and words alone cannot sufficiently describe how to make and use the invention in a reproducible manner, access to the biological material may be necessary for the satisfaction of the statutory requirements for patentability under 35 U.S.C. 112 [emphasis added]. However, as with other biological material deposited for purposes of patents for inventions under 35 U.S.C. 101, the deposit of plant material together with the written specification must enable those skilled in the art to make and use the claimed invention, in accordance with the requirements of 35 U.S.C. 112. See MPEP 2403.02. Moreover, MPEP 2163(I) also provides that "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 1613. An application specification may show actual reduction to practice by describing testing of the claimed invention or, in the case of biological materials, by specifically describing a deposit made in accordance with 37 CFR 1.801 et seq. See Enzo Biochem, 323 F.3d at 965, 63 USPQ2d at 1614 ( "reference in the specification to a deposit may also satisfy the written description requirement with respect to a claimed material" ); see also Deposit of Biological Materials for Patent Purposes, Final Rule, 54 FR 34,864 (August 22, 1989) ("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.). Such a deposit is not a substitute for a written description of the claimed invention. 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). In the instant matter, the specification only provides a description of the traits of the variety but is silent and/or incomplete with respect to the breeding history of said variety. This breeding history is critical because it provides the genetics of the variety and, in turn, its corresponding traits. Thus, in the absence of a breeding history, the specification has failed to provide an adequate written description of the claimed variety. 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. Or, 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). Conclusion No claim is allowed. The closest prior art appears to be Mack et al (Patent No. US 8,563,834 B1), which teaches hybrid corn variety 570007 having many of the same characteristics of the instantly claimed variety (see col. 5). However, hybrid corn variety 570007 does not have all of the traits of the instantly claimed variety.
