Office Action

§112
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Application Status This office action is in response to arguments filed in a pre-appeal brief conference request filed on May 15, 2026. Claims 11 – 20 are currently pending. Response to Arguments Applicant’s arguments have been fully considered. All previous grounds of rejections are withdrawn. New grounds of rejection are presented below for lack of written description. 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 11 – 20 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 independent claims both require a first sliding incline that directs the refrigerant compressor in a direction during an accident-induced displacement of the refrigerant compressor. Applicant has not reasonably conveyed to one skilled in the relevant art that they have possession of this claimed invention. Beyond brief exemplary descriptions of longitudinal forces arising from “frontal impact” or “head-on collision” of the motor vehicle yielding an accident-induced displacement, the specification fails to describe the characteristics of an accident-induced displacement, the chain of events that lead to directing the compressor in a direction along the sliding incline during an accident-induced displacement, and the forces necessary to achieve the above function. For example, the specification provides no range of forces needed to induce displacement and no structural relationship that causes the claimed displacement to occur. The absence of such descriptions leads one of ordinary skill in the art to speculate as to how to the claimed displacement occurs and how direction of the compressor by the incline is achieved, and indicates that applicant does not have possession of the claimed invention.
