Office Action

§112 §DP
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. The amendment dated 11/20/2025 has been considered and entered. The terminal disclaimer filed on 11/20/2025 has been approved. Therefore, the previous rejections based on obviousness double patenting are withdrawn. However, new rejections based on new matter are made below. Claim Rejections - 35 USC § 112 Claims 14, 15, 17 – 19, 21 – 24, 28, 32, 39 – 59 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. The claim includes a negative proviso which requires the absence of fatty acids in the composition in order to overcome the rejections in view of Theyssen et al. (US 2010/0009879). While applicant’s specification recites long chain fatty acids as ingredient on page 9 of the disclosure as originally filed, the recitation is not inclusive of all fatty acids (i.e., excludes short chain fatty acids of 8 carbon atoms or less) and there is no positive recitation of fatty acid as an ingredient in general to support the negative proviso. Allowable Subject Matter Claims 14, 15, 17 – 19, 21 – 24, 28, 32, 39 – 59 are objected to pending the rejections under 35 USC 112. The closest prior art by Seemeyer et al. (US 2008/0176778) and alternatively by Theyssen et al. (US 2010/0009879) each teach lubricant for conveyors having phosphate esters and emulsifiers, but Seemeyer fails to teach the specific phosphate of the claims, and Theyssen fails to teach a fatty acid free composition. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to TAIWO OLADAPO whose telephone number is (571)270-3723.
