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 . Priority Applicant’s claim for the benefit of a prior-filed application under 35 U.S.C. 119(e) or under 35 U.S.C. 120, 121, 365(c), or 386(c) is acknowledged. 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 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-8, 10, and 14-18 of U.S. Patent No. 12,136,273, as further detailed in the table below: Instant Application United States Patent No. 12,136,273 Claim 1. A system comprising: a sensing system of a vehicle, the sensing system configured to: obtain an image of a region of an environment of the vehicle; and a perception system of the vehicle, the perception system configured to: classify a first sign in the image as an image-true sign, wherein to classify the first sign as an image-true sign, the perception system is to identify the first sign as a sign whose mirror image corresponds to a valid sign type; and identify, based at least on a spatial relationship of the first sign and one or more objects in the region of the environment of the vehicle, the first sign as a real sign. Claim 1. A system comprising: a sensing system of a vehicle, the sensing system configured to: obtain a combined image comprising a camera image of a region of an environment of the vehicle and a depth information for the region of the environment of the vehicle, wherein the depth information comprises at least one of a lidar data, a radar data, a stereo image data, or an ultrasonic data; and a perception system of the vehicle, the perception system configured to: classify a first sign in the combined image as an image-true sign, wherein to classify the first sign as an image-true sign, the perception system is to identify the first sign as a sign whose mirror image corresponds to a valid sign type; perform a spatial validation of the first sign, the spatial validation comprising evaluation of a spatial relationship of the first sign and one or more objects in the region of the environment of the vehicle; and identify, based on the performed spatial validation, the first sign as a real sign. Claim 2 Claim 3 Claim 3 Claim 2 Claim 4 Claim 4 Claim 5 Claim 7 Claim 6 Claim 8 Claim 7 Claim 10 Claim 8 Claim 10 Claim 9. A system comprising: a sensing system of a vehicle, the sensing system configured to: obtain an image of a region of an environment of the vehicle; and a perception system of the vehicle, the perception system configured to: generate one or more scores characterizing a first sign in the image; obtain a classification of the first sign as a real sign or an image sign based on the one or more scores, wherein the one or more scores comprises a geometry score characterizing a likelihood that the first sign corresponds to a plurality of classes comprising at least: a class of image-true signs, wherein an image belonging to the class of image-true signs has a mirror image of a valid sign type, and a class of image-false signs, wherein an image belonging to the class of image-false signs has a mirror image of an invalid sign type; and cause a driving path of the vehicle to be determined in view of the obtained classification of the first sign. Claim 14. A method comprising: obtaining, using a sensing system of a vehicle, a combined image that comprises a camera image of a region of an environment of the vehicle and a depth information of the region of the environment of the vehicle, wherein the depth information comprises at least one of a lidar data, a radar data, a stereo image data, or an ultrasonic data; classifying a first sign in the combined image as an image-true sign, wherein classifying the first sign as an image-true sign the perception system comprises identifying the first sign as a sign whose mirror image is a valid sign; performing a spatial validation of the first sign, the spatial validation comprising evaluation of a spatial relationship of the first sign and one or more objects in the region of the environment of the vehicle; and identifying, based on the performed spatial validation, the first sign as a real sign. Claim 10 Claim 15 Claim 11 Claim 16 Claim 12 Claim 17 Claim 13 Claim 18 Claim 14 Claim 17 Claim 15. A method comprising: obtaining, using a sensing system of a vehicle, an image of a region of an environment of a vehicle; generating, using a perception system of the vehicle, one or more scores characterizing a first sign in the image; obtaining a classification of the first sign as a real sign or an image sign based on the one or more scores, wherein the one or more scores comprises a geometry score characterizing a likelihood that the first sign corresponds to a plurality of classes comprising at least: a class of image-true signs, wherein an image belonging to the class of image-true signs has a mirror image of a valid sign type, and a class of image-false signs, wherein an image belonging to the class of image-false signs has a mirror image of an invalid sign type; and causing a driving path of the vehicle to be determined in view of the obtained classification of the first sign. Claim 14. A method comprising: obtaining, using a sensing system of a vehicle, a combined image that comprises a camera image of a region of an environment of the vehicle and a depth information of the region of the environment of the vehicle, wherein the depth information comprises at least one of a lidar data, a radar data, a stereo image data, or an ultrasonic data; classifying a first sign in the combined image as an image-true sign, wherein classifying the first sign as an image-true sign the perception system comprises identifying the first sign as a sign whose mirror image is a valid sign; performing a spatial validation of the first sign, the spatial validation comprising evaluation of a spatial relationship of the first sign and one or more objects in the region of the environment of the vehicle; and identifying, based on the performed spatial validation, the first sign as a real sign. Claim 16 Claim 15 Claim 17 Claim 16 Claim 18 Claim 17 Claim 19 Claim 18 Claim 20 Claim 17 Although the conflicting claims are not identical, they are not patentably distinct from each other because the Patent claims include all the limitations of the instant application claims, respectively. The patent claims also include additional limitations. Hence, the instant application claims are generic to the species of invention covered by the respective patent claims. As such, the instant application claims are anticipated by the patent claims and are therefore not patentably distinct therefrom (See Eli Lilly and Co. v. Barr Laboratories Inc., 58 USPQ2D 1869, " a later genus claim limitation is anticipated by, and therefore not patentably distinct from, an earlier species claim", In re Goodman, 29 USPQ2d 2010, "Thus, the generic invention is 'anticipated' by the species of the patented invention" and the instant “application claims are generic to species of invention covered by the patent claim, and since without terminal disclaimer, extant species claim preclude issuance of generic application claims”).
