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 . Prior Art of Record The applicant's attention is directed to additional pertinent prior art cited in the accompanying PTO-892 Notice of References Cited, which, however, may not be currently applied as a basis for the following rejections. While these references were considered during the examination of this application and are deemed relevant to the claimed subject matter, they are not presently being applied as a basis for rejection in this Office action. The pertinence of these documents, however, may be revisited, and they may be applied in subsequent Office actions, particularly in light of any amendments or further clarification of the claimed invention. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. Claim(s) 1-20 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Chen et al.
