Office Action

§102 §112
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 . DETAILED ACTION All the references cited in the International Search Report have been considered. None is anticipatory to the amended claims. Election/Restrictions The applicant has elected Group III (claims 7 and 11-14) without traverse. This restriction is made FINAL. See previous action for the reasons for applying the restriction. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. Claim(s) 7 and 11-14 (is)are rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention. The language within parentheses, '(but the first….. from each other)”, is unclear and lacks a definitive meaning in the context of the claim. It is unclear what the applicant intends this parenthetical text to mean or how it relates to the remainder of the claim. As a result, the scope of the claim is ambiguous and does not particularly point out and distinctly define the metes and bounds of the invention. Claims 11-14 depend upon claim 7 and fail to rectify the issue in claim 1. See MPEP § 2173.05(d). Claim Rejections - Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory obviousness-type double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); and In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on a nonstatutory double patenting ground provided the conflicting application or patent either is shown to be commonly owned with this application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. Effective January 1, 1994, a registered attorney or agent of record may sign a terminal disclaimer. A terminal disclaimer signed by the assignee must fully comply with 37 CFR 3.73(b). Claim(s) 7 and 11-14 is (are) rejected on the ground of nonstatutory obviousness-type double patenting as being unpatentable over claims 1-9 of US 12497487. ‘487 (claims 1-9) meets instant claims 7 and 11-14 in an anticipatory manner, because it discloses: PNG media_image1.png 114 517 media_image1.png Greyscale PNG media_image2.png 555 511 media_image2.png Greyscale . Furthermore, one ordinary skill in the art would have expected the disclosed by ‘487 to feature the same haze value and Tg, because ‘487 obviously satisfy all the material and chemical limitations of the instant invention-see MPEP 2112.01. Claim(s) 7 and 11-14 is (are) rejected on the ground of nonstatutory obviousness-type double patenting as being unpatentable over claims 1-6 of US 12497488. ‘488 (claims 1-6) meets instant claims 7 and 11-14 in an anticipatory manner, because it discloses: PNG media_image3.png 200 400 media_image3.png Greyscale PNG media_image4.png 559 492 media_image4.png Greyscale PNG media_image5.png 99 507 media_image5.png Greyscale . The disclosed Df overlapping with the claimed range. It has been found that where claimed ranges overlap ranges disclosed by prior art, a prima facie case of obviousness exists - see MPEP 2144.05 I. 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). Therefore, it would have been obvious to one skilled in the art to have created/selected the claimed compositional elements from the composition disclosed in the‘488 since it discloses all applicants' components, values and methods of making. Furthermore, one ordinary skill in the art would have expected the disclosed by ‘487 to feature the same haze value and Tg, because ‘487 obviously satisfy all the material and chemical limitations of the instant invention-see MPEP 2112.01. 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. Claim(s) 7 and 11-14 is(are) rejected under 35 U.S.C. 102(a)(1) as being anticipated by Nakayama et al. (US 20130327982). As to claims 7 and 11-14, Yamaguchi (abs., examples, claims, figures, tables, 74) discloses a polyimide film (Ex.1-10, Comp Ex.1,4,7): PNG media_image6.png 228 982 media_image6.png Greyscale PNG media_image7.png 207 418 media_image7.png Greyscale PNG media_image8.png 237 912 media_image8.png Greyscale PNG media_image9.png 200 400 media_image9.png Greyscale The polyimide films in those examples would inherently exhibit the claimed properties of Df, haze, and Tg, dupability, and solubility, because in view of the substantially identical composition (in this case, the disclosed polyimide structure, i.e., comonomers and mol%), it appears that the adduct would have inherently possessed the claimed properties. See MPEP § 2112. Claim(s) 7, 11-12, and 14 is(are) rejected under 35 U.S.C. 102(a)(1) as being anticipated by Yamaguchi et al. (US 20100130628). As to claims 7, 11-12, and 14, Yamaguchi (abs., examples, claims, figures, tables, 70) discloses a polyimide film (Ex.3-5,8-9): PNG media_image10.png 200 400 media_image10.png Greyscale PNG media_image11.png 129 727 media_image11.png Greyscale PNG media_image12.png 138 627 media_image12.png Greyscale The polyimide films in those examples would inherently exhibit the claimed properties of Df, haze, and Tg, dupability, and solubility, because in view of the substantially identical composition (in this case, the disclosed polyimide structure, i.e., comonomers and mol%), it appears that the adduct would have inherently possessed the claimed properties. See MPEP § 2112. Claim(s) 7 is(are) rejected under 35 U.S.C. 102(a)(1) as being anticipated by Suto et al. (US 20190100624). As to claim 7, Yamaguchi (abs., examples, claims, figures, tables, 59) discloses a polyimide film (Ex.25-27 and 30): PNG media_image13.png 264 641 media_image13.png Greyscale PNG media_image14.png 200 400 media_image14.png Greyscale PNG media_image15.png 200 400 media_image15.png Greyscale PNG media_image16.png 200 400 media_image16.png Greyscale The polyimide films in those examples would inherently exhibit the claimed properties of haze and Tg, dupability, and solubility, because in view of the substantially identical composition (in this case, the disclosed polyimide structure, i.e., comonomers and mol%), it appears that the adduct would have inherently possessed the claimed properties.
