Office Action

§102 §103 §DP
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 . 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) 10-13 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Chia et al. (U.S. PGPUB. 2014/0196848 A1). INDEPENDENT CLAIM 10: Regarding claim 10, Chia et al. teach a shutter disc for use in a physical vapor deposition (PVD) processing chamber, comprising: a body, comprising: a center region comprising a center of the body and a cross-sectional wave shape, and an outer region comprising an outer edge of the body that is planar. (Figs. 1-4; Paragraphs 0016-0033; Annotated Figure Below) PNG media_image1.png 650 894 media_image1.png Greyscale DEPENDENT CLAIM 11: The difference not yet discussed is wherein the cross-section wave shape extends between the center and the outer region. Regarding claim 11, Chia et al. teach wherein the cross-section wave shape extends between the center and the outer region. (See Figs. 1, 2) DEPENDENT CLAIM 12: The difference not yet discussed is wherein a plurality of concentric crest portions of wave shapes extend between the center and the outer edge. Regarding claim 12, Chia et al. teach wherein a plurality of concentric crest portions of wave shapes extend between the center and the outer edge. (See Annotated Figure above) DEPENDENT CLAIM 13: The difference not yet discussed is wherein a plurality of concentric trough portions of wave shapes extend between the center and the outer edge. Regarding claim 13, Chia et al. teach wherein a plurality of concentric trough portions of wave shapes extend between the center and the outer edge. (Figs. 1, 2, Annotated Figure above) 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. 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) 15, 16 are rejected under 35 U.S.C. 103 as being unpatentable over Chia et al. (U.S. PGPUB. 2014/0196848 A1). DEPENDENT CLAIM 15: The difference not yet discussed is wherein a thickness of the body at the center region is in a range from 1.7 millimeters to 2.0 millimeters. Regarding claim 15, From Fig. 2 and the measurement 250 it appears that the center region can range from 1.5 mm to 7.6 mm. (Paragraph 0019; See Fig. 2 above; at 0.06 inches or 1.5 mm the center region is about 3 times this. 4.5 mm) DEPENDENT CLAIM 16: The difference not yet discussed is wherein a thickness of the body at the outer region is in a range from 4.5 millimeters to 5.5 millimeters. Regarding claim 16, From Fig. 2 and the measurement 250 it appears that the outer region can range from 1.5 mm to 7.6 mm. (Paragraph 0019; See Fig. 2 above; at 0.06 inches or 1.5 mm the center region is about 3 times this. 4.5 mm) The motivation for utilizing the features of Chia et al. is that it allows for improving pasting uniformity. (Paragraph 0005) Therefore, it would have been obvious to one of ordinary skill in the art at the time the invention was made to have utilized the features of Chia et al. because it allows for improving the pasting uniformity. 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 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); 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 nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer.
