Office Action

§102
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 . Examiner Note In view of the Appeal Brief filed on 05 May 2025, PROSECUTION IS HEREBY REOPENED. New ground of rejection are set forth below. To avoid abandonment of the application, appellant must exercise one of the following two options: (1) file a reply under 37 CFR 1.111 (if this Office action is non-final) or a reply under 37 CFR 1.113 (if this Office action is final); or, (2) initiate a new appeal by filing a notice of appeal under 37 CFR 41.31 followed by an appeal brief under 37 CFR 41.37. The previously paid notice of appeal fee and appeal brief fee can be applied to the new appeal. If, however, the appeal fees set forth in 37 CFR 41.20 have been increased since they were previously paid, then appellant must pay the difference between the increased fees and the amount previously paid. A Supervisory Patent Examiner (SPE) has approved of reopening prosecution by signing below: { 4 } Response to Amendment This is a Non-Final Detailed Action in response to the Appeal Brief on 05 May 2025. The present application claims 1-3, 5, 7, 11-13, 15, 17-21 and 27-32, submitted on 05 May 2025 are pending. Applicants’ cancelation of claims 4, 6, 8-10, 14, 16 and 22-26, indicated on 05 May 2025 has been acknowledged. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-3, 5, 7, 11-13, 15, 17-21 & 27-32 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Goodrich (U.S. Patent No. 5,667,871).
