Office Action

§112
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 Election/Restrictions Claims 1-8, and 15-26 are pending. Applicant’s election of Group I, claims 1-8, and 15-26, in the reply filed on 11/16/25 is acknowledged. Because applicant did not distinctly and specifically point out the supposed errors in the restriction requirement, the election has been treated as an election without traverse (MPEP § 818.03(a)). Claims 1-8, and 15-26 are examined on the merits. Claim Rejections –35 USC § 112, 2nd 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. Claims 1-8, and 15-26 are rejected under 35 U.S.C. 112, second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which applicant regards as the invention. Claim 1 recites “A method of extracting cannabinoids and cannabidiol acids in oxidized state…” at line 1-2; and “extracting bioactive materials as one or more of cannabinoids and cannabinoids acids” at line 6. The recitation is very confusing, does Applicant mean “cannabidiol acids” or “cannabinoids acids”? What do “cannabidiol acids” refer to? Claim 1 (at line 2) recites parenthetical expression "(Cannabis sativa L.)". The metes and bounds of Claim 1 are rendered vague and indefinite by the parenthetical recitation of "(Cannabis sativa L) because it is unclear as to whether the limitation is part of the instantly claimed subject matter. Therefore, the metes and bounds of claims are rendered vague and indefinite. The lack of clarity renders the claims very confusing and ambiguous since the resulting claims do not clearly set forth the metes and bounds of the patent protection desired. All other cited claims depend directly or indirectly from rejected claims and are, therefore, also, rejected under U.S.C. 112, second paragraph for the reasons set forth above. Conclusion No claim is allowed. Any inquiry concerning this communication or earlier communications from the examiner should be directed to QIUWEN MI whose telephone number is (571)272-5984.
