Office Action

§102 §103
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 . In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. Examiner's Note. Examiner has cited particular paragraphs and/or columns and line numbers and/or figures in the references as applied to the claims below for the convenience of the applicant. Although the specified citations are representative of the teachings in the art and are applied to the specific limitations within the individual claim, other passages and figures may apply as well. It is respectfully requested from the applicant, in preparing the responses, to fully consider the references in entirety as potentially teaching all or part of the claimed invention, as well as the context of the passage as taught by the prior art or disclosed by the examiner. The Examiner notes that it has been held that a recitation that a structural element is "adapted to", “configured to”, “capable of”, “arranged to”, “intended to”, "so as" or “operable to” perform a function does not limit the claim to a particular structure and thus only requires the ability to so perform the function. (See In re Hutchison, 69 USPQ 138. See also, MPEP 2111.04) As such, under the broadest reasonable interpretation of the claims and the prior art, the recitations of "adapted to", “configured to”, “capable of”, “arranged to”, “intended to”, "so as" or “operable to” will be deemed met by an element in the prior art capable of performing the function recited in connection with "adapted to", “configured to”, “capable of”, “arranged to”, “intended to”, "so as" or “operable to”. The Examiner has cited particular paragraphs or columns and line numbers in the references applied to the claims above for the convenience of the applicant. Although the specified citations are representative of the teachings of the art and are applied to specific limitations within the individual claim, other passages and figures may apply as well. It is respectfully requested of the applicant in preparing responses, to fully consider the references in their entirety as potentially teaching all or part of the claimed invention, as well as the context of the passage as taught by the prior art or disclosed by the Examiner. SEE MPEP 2141.02 [R-07.2015] VI. PRIOR ART MUST BE CONSIDERED IN ITS ENTIRETY, INCLUDING DISCLOSURES THAT TEACH AWAY FROM THE CLAIMS: A prior art reference must be considered in its entirety, i.e., as a whole, including portions that would lead away from the claimed invention. W.L. Gore & Associates, Inc. v. Garlock, Inc., 721 F.2d 1540, 220 USPQ 303 (Fed. Cir. 1983), cert, denied, 469 U.S. 851 (1984). See also MPEP §2123. Claim Objections Claims 1, 7, 19 are objected to because of the following informalities: The term “being” are not positive limitations inasmuch as the terms including the word "being" are passive and thus do not serve to clearly limit the structure in an active sense. Appropriate correction is required. The above are only examples of such informalities. The Applicant is required to review the entire claims and correct all such informalities. Reference of prior art Roder et al. (US 20070069081, Demiseable Momentum Exchange System). Bialke. (US 20080099626, Reconfigurable Reaction Wheel For Spacecraft). Marshall et al.
