Office Action

§112 §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 1-4 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 11 and 12 of U.S. Patent No. US 11,412,208 B2 (reference patent). Although the claims at issue are not identical, they are not patentably distinct from each other because Consider application claim 3, claim 11 of reference patent discloses a three-dimensional data encoding device that encodes a plurality of three-dimensional points, the device comprising: a processor; and a memory, wherein by using the memory, the processor performs: selecting one prediction mode from two or more prediction modes, the two or more prediction modes each being for selecting a three-dimensional point which is to be referenced when a predicted value of an attribute information item of a first three-dimensional point is calculated; and binarizing the selected one prediction mode, based on a total number of the two or more prediction modes, the total number of the two or more prediction modes is determined in response to a number of one or more second three-dimensional points provided in vicinity of the first three-dimensional point, and the one or more second three-dimensional points include the three-dimensional point, and the one or more second three-dimensional points are available to be referenced when the predicted value is calculated. Claim 11 of reference patent discloses all the limitations in the application claim. Thus, non-statutory double patenting applies. Consider application claim 4, claim 12 of reference patent discloses a three-dimensional data decoding device that decodes a plurality of encoded three-dimensional points, the device comprising: a processor; and a memory, wherein by using the memory, the processor performs: obtaining one prediction mode from two or more prediction modes, the two or more prediction modes each being for selecting a three-dimensional point which is to be referenced when a predicted value of an attribute information item of a first three-dimensional point is calculated, the obtained one prediction mode is binarized, based on a total number of the two or more prediction modes, the total number of the two or more prediction modes is determined in response to a number of one or more second three-dimensional points provided in vicinity of the first three-dimensional point, and the one or more second three-dimensional points include the three-dimensional point, and the one or more second three-dimensional points are available to be referenced when the predicted value is calculated. Claim 12 of reference patent discloses all the limitations in the application claim. Thus, non-statutory double patenting applies. Consider application claim 1, application claim 1 recites the method implemented by the device recited in claim 3. Thus, it is rejected for the same reasons. Consider application claim 2, application claim 2 recites the method implemented by the device recited in claim 4. Thus, it is rejected for the same reasons. Claims 1-4 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 3-4 of U.S. Patent No. US 11,716,459 B2 (reference patent). Although the claims at issue are not identical, they are not patentably distinct from each other because Consider application claim 3, claim 3 of reference patent discloses A three-dimensional data encoding device comprising: a processor; and a memory, wherein by using the memory, the processor performs: selecting one prediction mode from two or more prediction modes, the two or more prediction modes each being for selecting a three-dimensional point which is to referenced when a predicted value of an attribute information item of a first three-dimensional point is calculated; and binarizing the selected one prediction mode based on a total number of the two or more prediction modes, wherein the total number is determined in response to a number of one or more second three-dimensional points including the three-dimensional point provided in vicinity of the first three-dimensional point, the one or more second three-dimensional points being available to be referenced when the predicted value is calculated, and the attribute information item includes color information. Claim 3 of reference patent discloses all the limitations in the application claim. Thus, non-statutory double patenting applies. Consider application claim 4, claim 4 of reference patent discloses a three-dimensional data decoding device comprising: a processor; and a memory, wherein by using the memory, the processor performs: obtaining one prediction mode from two or more prediction modes, the two or more prediction modes each being for selecting a three-dimensional point which is to be referenced when a predicted value of an attribute information item of a first three-dimensional point is calculated, the obtained one prediction mode is binarized based on a total number of the two or more prediction mode, the total number is determined in response to a number of one or more second three-dimensional points including the three-dimensional point provided in vicinity of the first three-dimensional point, the one or more second three-dimensional points being available to be referenced when the predicted value is calculated, and the attribute information item includes color information. Claim 4 of reference patent discloses all the limitations in the application claim. Thus, non-statutory double patenting applies. Consider application claim 1, application claim 1 recites the method implemented by the device recited in claim 3. Thus, it is rejected for the same reasons. Consider application claim 2, application claim 2 recites the method implemented by the device recited in claim 4. Thus, it is rejected for the same reasons. Claims 1-4 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 3-4 of U.S. Patent No. US 12,166,964 B2 (reference patent). Although the claims at issue are not identical, they are not patentably distinct from each other because Consider application claim 3, claim 3 of reference patent discloses a three-dimensional data encoding device comprising: a processor; and a memory, wherein by using the memory, the processor performs: selecting one prediction mode from two or more prediction modes, the two or more prediction modes each being for selecting a three-dimensional point which is to referenced when a predicted value of an attribute information item of a first three-dimensional point is calculated; and binarizing the selected one prediction mode, based on a total number of the two or more prediction modes, the total number is determined in response to a number of one or more second three-dimensional points including the three-dimensional point neighboring the first three-dimensional point, the one or more second three-dimensional points being available to be referenced when the predicted value is calculated, and the attribute information item includes reflectance information. Claim 3 of reference patent discloses all the limitations in the application claim. Thus, non-statutory double patenting applies. Consider application claim 4, claim 4 of reference patent discloses a three-dimensional data decoding device comprising: a processor; and a memory, wherein by using the memory, the processor performs: obtaining one prediction mode from two or more prediction modes, the two or more prediction modes each being for selecting a three-dimensional point which is to be referenced when a predicted value of an attribute information item of a first three-dimensional point is calculated, and the obtained one prediction mode is binarized, based on a total number of the two or more prediction mode, the total number is determined in response to a number of one or more second three-dimensional points including the three-dimensional point neighboring the first three-dimensional point, the one or more second three-dimensional points being available to be referenced when the predicted value is calculated, and the attribute information item includes reflectance information.

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. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim 1 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 1 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being incomplete for omitting essential steps, such omission amounting to a gap between the steps. See MPEP § 2172.01. The omitted steps are: 1) selecting prediction mode; 2) calculating a predicted value of an attribute information item of a first three-dimensional point; 3) determining the total number of the two or more prediction modes; 4) referencing the one or more second three-dimensional points. In other words, the essential steps of the encoding method are omitted.
