Office Action

§112
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 . DETAILED ACTION 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. Claims 1-2, 4-9 and 12 are rejected under 35 U.S.C. 112(a) 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 at the time the application was filed, had possession of the claimed invention. 1) Claim 1 discloses limitations: “wherein the first end of the second connection portion has a third surface, and the second end of the second connection portion has a fourth surface, and a fifth surface intersecting the third and fourth surfaces of the second connection portion, the second connection portion has an L-shape formed by the third, fourth, and fifth surfaces.” There is no support for these limitations in the specification. Fig 7 clearly discloses the third surface 41, the fifth surface 43, the convex surface 45, the fourth surface 42 and the outer surfaces 44. The fourth and fifth surfaces 43 and 42 clearly do not intersect, since there is a convex surface 45 between them. Also, the surfaces 41, 43 and 42 do not form an L-shape, by definition, “L” can only be formed by two surfaces, not three. 2) Claim 1 discloses a limitation: “a sixth surface intersecting the firth and second surfaces of the first connection portion”. There is no disclosure of a firth surface. The remainder of the claims are rejected for their dependence on claim 1. For the purpose of examination, the limitations as presented have been searched and considered. Admitted Prior Art The rejections of claim 1 (connecting every electrode pad of the device to one of the pins of the package), claim 12 (choosing the materials so that the heatsink has a higher thermal conductivity than the carrier), and claim 9 (connection portions made of an insulating material with a metal pattern) based on the well-known in the art statements are taken to be admitted prior art (hereinafter APA1, APA2 and APA3, respectively) because applicant either failed to traverse the examiner’s assertion of official notice or that the traverse was inadequate, see MPEP 2144.03. Response to Arguments Applicant’s arguments filed on 01/16/26 have been considered but they are moot in view of new grounds of rejection. Pertinent Art The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Applicant’s attention is drawn to the references cited on form PTO-892 in the previous office action which lists other references with similar features as the invention. However, none of them anticipate all the features of the pending claims. 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.
