Office Action

§112
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. Claims 1-5 and 7-20 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 applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 1 is rejected for the recitation of “…a pour point equal to or lower than -30̊C and boiling point equal to or higher than 350̊C”. It is unclear how an infinite pour point lower than -30 degrees Celsius or an infinite boiling point above 350 degrees Celsius could be attained. Applicant is advised to amend the claim language to recite a closed range. Support in the specification appears to exist for a lower limit on the boiling point of -50 degrees Celsius and an upper limit on the boiling point of 476 degrees Celsius. Claim 7 is rejected for the recitation of “…a pour point equal to or lower than -40̊C and boiling point equal to or higher than 400̊C”. It is unclear how an infinite pour point lower than -40 degrees Celsius or an infinite boiling point above 400 degrees Celsius could be attained. Applicant is advised to amend the claim language to recite a closed range. Support in the specification appears to exist for a lower limit on the boiling point of -50 degrees Celsius and an upper limit on the boiling point of 476 degrees Celsius. Response to Arguments Applicant’s arguments, see Remarks, filed 11/19/2025, with respect to the claims have been fully considered and are persuasive. The 35 USC 103 rejection of the standing claims has been withdrawn. Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to SHAWN MCKINNON whose telephone number is (571)272-6116.
