Office Action

§102 §103
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 . Election/Restrictions Applicant’s election without traverse of claims 1-4 in the reply filed on 12/18/2025 is acknowledged. Claims 5-10 and 12-21 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected Invention, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 12/18/2025. Status of Claims Claims 1-10 and 12-21 are currently pending in the application, of claims 6-10 and 12-21 are withdrawn from consideration. Claims 1-4 are being examined on the merits in this Office Action. 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) 1-2 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Pekala et al. (WO 2005/0699272 A2). The Examiner has provided original document of WO 2005/0699272 A2 (PCT/US2005/001654). The citation of the prior art in this rejection refer to this document. Regarding claim 1, Pekala teaches a freestanding film (i.e., freestanding polymer film) (40) (paragraph [0013]) comprising a pattern (i.e., ribs) (46) having directionality on at least one surface (i.e., upper major surface) (42) (paragraph [0031]-[0033]). Regarding claim 2, Pekala teaches the patter is a concave-convex pattern (as shown in figure 3B below) (paragraph [0033]). PNG media_image1.png 452 442 media_image1.png Greyscale Claim Rejections - 35 USC § 103 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 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim(s) 3-4 is/are rejected under 35 U.S.C. 103 as being unpatentable over Pekala et al. (WO20050699272A2). Regarding claim 3, Pekala teaches the patter has an interval of 25-500µm (paragraph [0031]-[0032]) which overlaps the claimed range. It is noted that Pekala differ in the exact same interval range as recited in the instant claim however, one of ordinary skill in the art before the effective filing date of the claimed invention would have considered the invention to have been obvious because the interval range of Pekala overlap the instant claimed range and therefore is considered to establish a prima facie case of obviousness. It has been held in the courts that in the case where the claimed ranges "overlap or lie inside ranges disclosed by the prior art" a prima facie case of obviousness exists. In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976); In re Woodruff, 919 F.2d 1575, 16 USPQ2d 1934 (Fed. Cir. 1990). Regarding claim 4, Pekala teaches the pattern has a depth of 5% to 100% of the thickness of the freestanding film (i.e., polymer film 40 preferably has a film thickness 50 that is between about 50 microns and about 500 microns, and ribs 46 preferably have a rib height 52 that is between about 5% and about 100% of film thickness 50) (paragraph [0031]-[0033]) which overlaps the claimed range. For instance, a 5% of 50µm is 2.5µm and 100% of 50µm is 50µm. It is noted that Pekala differ in the exact same depth range as recited in the instant claim however, one of ordinary skill in the art before the effective filing date of the claimed invention would have considered the invention to have been obvious because the depth range of Pekala overlap the instant claimed range and therefore is considered to establish a prima facie case of obviousness. It has been held in the courts that in the case where the claimed ranges "overlap or lie inside ranges disclosed by the prior art" a prima facie case of obviousness exists. In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976); In re Woodruff, 919 F.2d 1575, 16 USPQ2d 1934 (Fed. Cir. 1990). Pertinent Prior Art The following prior art made of record and not relied upon is considered pertinent to applicant's disclosure: Ferreira et al. (U.S. Patent 7,682,738). Ferreira teaches a freestanding film (i.e., spacer) (20) comprising a pattern (i.e., ridges) having directionality at least in one surface (see figure 3) (C20:L855).
