CTNF 18/589,561 CTNF 76411 DETAILED ACTION Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Claim Rejections - 35 USC § 112 07-30-01 AIA 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. 07-31-02 AIA Claim s 1-21 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 enablement requirement. The claim(s) contains 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. Independent claims 1 and 11 recited that the first transistor, second transistor, third transistor, fourth transistor, fifth transistor, and sixth transistor. However, the specification does not explain what circuits (or transistors) comprise the first transistor, second transistor, third transistor, fourth transistor, fifth transistor, and sixth transistor. Without some disclosures as to what constitutes the first transistor, second transistor, third transistor, fourth transistor, fifth transistor, and sixth transistor, one skilled in the art not be able to make and use the first transistor, second transistor, third transistor, fourth transistor, fifth transistor, and sixth transistor. Independent claim 18 recited that the first transistor, second transistor, and third transistor. However, the specification does not explain what circuits (or transistors) comprise the first transistor, second transistor, and third transistor. Again, without some disclosures as to what constitutes the first transistor, second transistor, and third transistor, one skilled in the art not be able to make and use the first transistor, second transistor, and third transistor .
