Office Action

§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 . 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. Claims 1 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of U.S. Patent No. US 12, 189, 150 B2.Claims 1-13 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-13 of U.S. Patent No. 12, 189, 150. Although the claims at issue are not identical, they are not patentably distinct from each other because: Instant Application: 1. A lenticular diffuser, comprising: a substantially smooth surface, wherein the substantially smooth surface defines a display axis extending perpendicular to the substantially smooth surface Patent No. US 12, 189, 150: A lenticular diffuser, comprising: a second substantially smooth surface substantially perpendicular to the display axis and a structured surface comprising a plurality of microstructures defining a plurality of substantially parallel grooves extending along a plane substantially perpendicular the display axis and a second structured surface comprising a plurality of second microstructures defining a second plurality of substantially parallel grooves extending along a plane substantially perpendicular the display axis wherein the structured surface comprises a plurality of microstructures each comprising a lenticular prism having linear end sections connected by a blend section separated by a substantially flat land area wherein the second structured surface comprises a plurality of second microstructures each comprising a lenticular prism having linear end sections connected by a blend section separated by a substantially flat land area wherein the blend section shape is a segment of an ellipse or 2nd, 4th or 6th order polynomial, and wherein the linear end sections comprise at least about 5% of the lenticular prism wherein the blend section shape is a segment of an ellipse or 2"d, 4* or 6* order polynomial, and wherein the linear end sections comprise at least about 5% of the lenticular prism wherein a cross section of each lenticular prism extends along a plane substantially parallel to the display axis in a direction from the substantially smooth surface to a vertex wherein a cross section of each lenticular prism extends along a plane substantially parallel to the display axis in a direction from the second substantially smooth surface to a vertex and wherein the lenticular diffuser refracts light that is substantially collimated in a first plane toward a second plane substantially perpendicular to the first plane. and wherein the lenticular diffuser refracts light substantially collimated in the first plane toward a second plane substantially perpendicular to the first plane. Claims 2-13 in the instant application are equivalent to claims 2-13 in patent U.S. Patent No. US 12,189,150 B2.
