Office Action

§101 §112
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Response to Arguments Applicant’s arguments with respect to claim(s) 5 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim 5 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding claim 5, the claim recites “a method of transmitting a bitstream”. The body of the claim, however, omits any method steps and has a plurality of wherein clauses that appear to describe a bitstream instead. It is therefore unclear whether the claimed invention is a method or a bitstream. Examiner notes that if applicant’s intention is to claim a method of transmitting a bitstream, the claim, as currently written, would be subject to a rejection under 35 U.S.C. 112. Because the claim, as currently written, omits any steps, including an essential transmitting step, the omission would amount to a gap between the steps under MPEP §2172.01. Examiner further notes that if applicant’s intention is to claim a bitstream, the claim, as currently written, would be subject to a rejection under 35 U.S.C. 101 because a bitstream (data) does not fall within one of the four statutory categories. Allowable Subject Matter Claims 1 – 4 are allowed. Claim 5 is objected to as allowed, pending resolution of the 35 U.S.C. 112 rejection. 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.
