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 . Election/Restrictions Claims 12-17 and 19 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected group, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 2/27/26. 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 1-11 and 20-22 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 subject matter which was not described in the original disclosure is the medical device comprised of three housing--a device housing with electrode, a first housing with a second electrode, and a battery housing—in combination with the other elements or manufacturing steps of the claim(s). The original disclosure taught two housings—a battery housing (e.g. figure 1, element 109, etc.) connected to the device housing with electrode (e.g. figure 1, elements 102 and 106, etc.). The device further has a header unit 103 with a second electrode 104 on the outside of the header unit, but never calls the header unit a housing or states that it houses or contains any element. In addition, the method of manufacture (e.g. figure 10, etc.) only discloses the manufacturing being performed with two housings and not three. The header is set forth as a structure appended to the device housing that holds on the outside of the header an electrode (e.g. the cited art of Mann showing the use of an electrode attached to the outside of a structure, figure 7, etc.). Response to Arguments Applicant’s arguments with respect to the claims have been considered but are moot in view of the new ground of rejection necessitated by amendment. Conclusion The prior art made of record is considered pertinent to applicant's disclosure and show several other pieces of prior art that are capable of meeting the limitations of the claims and the use of external electrodes on the outside of a housing. 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.
