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 . 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 12 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. Claim 12 recites the limitation "the concentrate" in lines 1-2. There is insufficient antecedent basis for this limitation in the claim. Allowable Subject Matter Claims 1-11, 13-17 and 23-31 are allowed. The closest prior art known to the Examiner is listed on the attached PTO 892 and 1449 forms. Specifically, while the prior art discloses the production of imidazoline compounds from soybean oil based fatty acids and further discloses the reduction of glycerol content in coffee oil based fatty acids to make imidazolines, none of the prior art discloses compositions or methods utilizing glycerol restricted soybean oil fatty acids as defined in the independent claims nor is there any teaching, suggestion or motivation in the prior art to arrive at the claimed material. Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to JAISON P THOMAS whose telephone number is (571)272-8917. The examiner can normally be reached Monday to Friday, 9:00 am-3:30 pm EST.
