Office Action

§DP
DETAILED ACTION 1. This communication is being filed in response to the submission having a mailing date of (01/08/2025) in which a three (3) month Shortened Statutory Period for Response has been set. Notice of Pre-AIA or AIA Status 2. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Acknowledgements 3. Upon initial entry, claim (1 -20) appears pending, of which claims (1, 9 and 17) are the three (3) parallel running independent claims on record. Information Disclosure Statement 4. The Information Disclosure Statement (IDS) that were submitted on date 07/21/2025, (2 papers) are PARTIALLY in compliance with the provisions of 37 CFR 1.97. Accordingly, the IDS’s have been considered by the examiner. 4.1. Multiple entries from the IDS(s) have been discarded, for failure to cite the relevant pages in the publication. Each of the submitted publications must comply with the 37 CFR 1.98 provisions, in order evaluate the corresponded information listed, to be considered by the Office. See also MPEP [37 CFR 1.98(b); - Each publication must be identified by publisher, author (if any), title, relevant pages of the publication, and date and place of the publication.] Specification 5. The lengthy specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant's cooperation is requested in correcting any errors of which applicant may become aware in the specification. Drawings 6. The submitted Drawings dated on (10/30/2024) has been accepted and considered under the 37 CFR 1.121 (d). Double Patenting 7. 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 obviousness-type 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); and In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). 7.1. 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 a nonstatutory double patenting ground provided the conflicting application or patent either is shown to be commonly owned with this application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. Effective January 1, 1994, a registered attorney or agent of record may sign a terminal disclaimer. A terminal disclaimer signed by the assignee must fully comply with 37 CFR 3.73(b). 7.2. Individuals associated with the filing and prosecution of the instant patent application have a duty to disclose information within their knowledge as to other copending United States applications which are "material to patentability" of the application in question. See MPEP §2001.06(b) for more details. 7.3. Independent claims (1, 9 and 17) and the associated dependencies of instant 18/932,496, also directed to a Method, Device and CRM of the same, being provisionally rejected on the ground of nonstatutory obvious-type double patenting as being unpatentable over the analogous device/method claims of the parent Appl. 17/146,349, (US 11,575,928 B2) and 18/155,641 (US 12167,027 B2). Although the conflicting claims are not identical, they are not patentably distinct from each other, because the claims use similar inventive step/scope methodology, and/or variations of the same claim language.
