Election/Restrictions The applicant has elected Group IV (claims 11-12 and 17) without traverse. This restriction is made FINAL. See previous action for the reasons of applying restriction. 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. Claim(s) 11-12 and 17 (is)are rejected under 35 U.S.C. 112(b) 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. Claims 11-12 and 17 lack of articles at the beginning of the claims. Regarding claim 11, the phrases " particular" and “obtainable” in claim 11 are indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. Claim 11 fails to define Sp. Claim 12 depend upon claim 11 and fail to rectify the issue in claim 11. See MPEP § 2173.05(d) Claim 17 fails to define SD. It is duly notified all nonelected claims lack of articles at the beginning of the claims. Nonelected claims 6 and 18 and use claims and would be subjected to 101/112b rejections.
