Office Action

§DP
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, 3-16, and 18-20 rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 3-16 and 18-20 of U.S. Patent No. 12098328. Although the claims at issue are not identical, they are not patentably distinct from each other because has all claim limitations and additional claim limitations. Applicant is reminded that those portions of the specification which provide support for the patent claims may also be examined and considered when addressing the issue of whether a claim in an application defines an obvious variation of an invention claimed 1n the patent. In re Vogel, 422 F. 2d 438, 164 USPQ 619, 622 (CCPA 1970). Allowable Subject Matter There is no allowable subject matter due to the double patenting rejection. Below is a listing of the prior art showing what is taught and not taught. Mariano (US 11846034 B1) teaches a gasification unit, a reactor to produce syngas, an optional scrubber and Fischer Tropsch reactor, and a reverse gas shift reactor. It does not teach the scrubber removing carbon dioxide. It does not teach routing the carbon dioxide from the scrubber to the reverse water shift reactor. It does not teach the carbon conversion rate. It does not teach anything about the feedstock. Greager (US 2022/0112429) teaches a process for producing syngas and fuel from it. A biomass goes to a gasification unit. A reactor converts the syngas to produce a ratio of hydrogen to carbon monoxide. A reverse water gas shift reaction unit generates carbon monoxide for later Fischer Tropsch reaction. There is an electrolysis unit. It does not teach the presence of any scrubber in communication with the second reactor generating the purified syngas. It does not teach the scrubber providing carbon dioxide to the reverse water gas shift reactor. It does not teach the carbon conversion rate of the feedstock. Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to FRANK C CAMPANELL whose telephone number is (571)270-3165. The examiner can normally be reached Monday-Friday 9:00-5:00. Examiner interviews are available via telephone, in-person, and video conferencing using a USPTO supplied web-based collaboration tool.
