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.
3.Claims 11, 14-16, 17 are 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 pre-AIA the applicant regards as the invention.
Claim 14 recites as the plurality of slave BMSs enters the target identification mode, identification paths connecting the identification signal generator to the respective identification signal detectors of the plurality of slave BMSs are activated. There is no antecedent basis for identification signal generator and detector and it is not clear where is the identification signal generator. For examination purpose, claim 14 has been interpretated as “as the plurality of slave BMSs enters the target identification mode, identification paths connecting an identification signal generator of the master MBS to respective identification signal detectors of the plurality of slave BMSs are activated.”
Claims 15 and 16 are rejected for the same reason because they depend on claim 13.
Claim 11 and claim 17 recites “wherein the identification signal uses a high frequency that is distinguished from a frequency of the power from the respective battery modules of the plurality of slave BMSs.
The term “high frequency” in claim 11, and 17 is a relative term which renders the claim indefinite. The term “high frequency” is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. For examination purpose, the limitation has been interpretated as wherein the identification signal uses a frequency that is higher than a frequency of the power from the respective battery modules of the plurality of slave BMSs.’
