Office Action

§102
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 . Response to AmendmentArguments Predicated on an inadvertent indication of allowable subject matter in claim 12, where claim 13 had clearly been intended insofar as (i) claim 12 was identified as containing allowable subject matter but dependent from a rejected claim two lines after an explanation of its unpatentability was given on page 3 of the 10/23/25 Office communication, (ii) the PTO-326 form indicates the proper claim, claim 13, as being objected to and (iii) the reasons given for holding the claim 12 as objected to, not rejected, pertain entirely to the subject matter of claim 13. Claim Rejections - 35 USC § 102 (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 12, 14-15, and 18-26 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Chen, CN 101787244 for the reasons outlined previously with the exception that that examiner had characterized the composition to which the anticipatory compound had been added as a coating when, in fact, [0065-0066] summarize the makeup of an adhesive. Claims 18-26 mirror exactly the subject matter of cancelled claims 2 to 8, 16, and 17 respectively, all of which had been earlier deemed to disclose unpatentable subject matter. Allowable Subject Matter Claim 13 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims for the reasons outlined previously. As an aside, it would be unusual to provide water as a component of a kit, unless perhaps the water was required to be of a purity not readily available.
