Office Action

§112
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 . Response to Arguments Applicant’s amendments/arguments on “a ground inductor included in the cap wafer” have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made due to lack of support in the original disclosure. Claim Objections Claim 1 and 15 are objected to because of the following informalities: Claim 1 line 6, claim 15 line 7, each has “the cap wafer” that appears to correctly be --the cap layer-- for antecedent basis and terminology. Appropriate correction is required. 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 1-20 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. Claim 1 recites “a ground inductor included in the cap wafer” (described in [0071]-[0072] and Fig. 1D) and “an electrical shield layer disposed on the bottom side of the cap layer” (described in [0059] and Fig. 1A), however, the original disclosure does not support both the ground inductor and the shield layer exist together. The ground inductor and the shield layer are separately described in different embodiments (Fig. 1D and 1A respectively). “The ground inductor is formed where the shield electrode is formed” ([0072]) also suggest the shield electrode is replaced. Since there are no support for the ground inductor and the shield layer exist together, thus claim 1 fails to comply with the written description requirement. Claims 15, 19 are rejected for fail to comply with written description requirement as similar to claim 1 above. Claims 2-14, 16-18, 20 are rejected due to dependency on claims 1, 15 and 19. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action. /A.W/Examiner, Art Unit 2843 /ANDREA LINDGREN BALTZELL/Supervisory Patent Examiner, Art Unit 2843
