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 . Information Disclosure Statement The Information Disclosure Statement(s) submitted by applicant on 6/28/2017 has/have been considered. The submission is in compliance with the provisions of 37 CFR § 1.97. Form PTO-1449 signed and attached hereto. Double Patenting 1. 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 claims at issue 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). 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 reference 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. A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The USPTO internet Web site contains terminal disclaimer forms which may be used. Please visit http://www.uspto.gov/forms/. The filing date of the application will determine what form 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 http://www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp. Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-27 of U.S. Patent No. US 11,909,765. Although the conflicting claims are not identical, they are not patentably distinct from each other because the subject matter claimed in the instant application is substantially similar in nature and anticipated by U.S. Patent No. US 11,909,765. See the table below: Instant Application U.S. Patent No. US 11,909,765. 1. A method for authenticating a user seeking access to a secure resource, the method comprising: at a first time, allowing the user to access the secure resource on a first client node on the basis of a first authentication mode; enrolling one or more wireless devices co-located with the user; and at a second time after the first time, allowing the user to access the secure resource on a second client node on the basis of a second authentication mode, wherein the second authentication mode comprises co-location of one or more enrolled wireless devices with the user. 2.

Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-34 of U.S. Patent No. US 10,333,980. Although the conflicting claims are not identical, they are not patentably distinct from each other because the subject matter claimed in the instant application is substantially similar in nature and anticipated by U.S. Patent No. US 10,333,980. Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent No. US 12,323,467. Although the conflicting claims are not identical, they are not patentably distinct from each other because the subject matter claimed in the instant application is substantially similar in nature and anticipated by U.S. Patent No. US 12,323,467. This is a nonstatutory double patenting rejection. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Sadler et al. (US 8893284 B2) discloses a method and system for extending an authentication of a wireless device are disclosed. For example, the method includes authenticating access to the wireless device via a first authentication. The method detects a bonded authentication device as a second authentication. The method permits access to the wireless device when the bonded authentication device is detected. Louboutin et al.( US 8925069 B2) discloses authentication techniques for electronic devices can provide more seamless communication between two devices. A first device (e.g., a host device) can maintain a list of known-good devices (e.g., accessory devices) with which it can interoperate. Information identifying a second device can be added to the known-good list when the second device successfully connects to the first device and completes an authentication process. After the second device disconnects, the first device can retain the identifying information on the known-good list for a predetermined period of time, after which the information can expire. If the second device reconnects to the host before its information expires, the authentication process can be bypassed.
