Office Action

§102
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 . Election/Restrictions Applicant's election with traverse of Species II with Subspecies IIA and Subspecies IIC readable on claims 21-39 in the reply filed on April 13, 2026 is acknowledged. The traversal is on the ground(s) that the restriction requirement distinguishes Species I from Species II based on the vehicle-level positioning of the CVT relative to the engine. No pending claim recites any limitation corresponding to this distinction. This is not found persuasive because claims themselves are never species. The scope of a claim may be limited to a single disclosed embodiment (i.e., a single species, and thus be designated a specific species claim). Alternatively, a claim may encompass two or more of the disclosed embodiments (and thus be designated a generic or genus claim). Species always refer to the different embodiments of the invention. MPEP 806.04(e) The requirement is still deemed proper and is therefore made FINAL. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 21-39 are rejected under 35 U.S.C. 102(a)(1)(a)(2) as being anticipated by Davis, U.S. Patent Publication 2018/0245682.
