Office Action

§112
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 . DETAILED ACTION This office action is in response to the RCE and IDS filed on 05/01/2026. Claims 1-20 are currently pending. Claims 1-20 are rejected. Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after allowance or after an Office action under Ex Parte Quayle, 25 USPQ 74, 453 O.G. 213 (Comm'r Pat. 1935). Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, prosecution in this application has been reopened pursuant to 37 CFR 1.114. Applicant's submission filed on 05/01/2026 has been entered. 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 20 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 recites the limitation “wherein the plurality of devices includes the first device and is to provide a service using the virtual address”. Examiner is not clear about which of the plurality of devices or the first device, but not both, is to provide a service. Thus, the scope of the subject-matter for which protection is sought is not clearly defined, contrary to the requirements of 35 USC § 112. A similar problem exists in Independent claim 11, and Independent claim 20. Thus, claims 1, 11 and 20 are rejected for being vague and indefinite. Claims 2-10, 12-19 are also rejected for depending from rejected base claims. Allowable Subject Matter Claims 1, 11, 20, and claims that depend from them, would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure includes: Bajaj (US 20190149463 A1) is pertinent to a method for providing automatic router assignment in a virtual environment involves receiving a gratuitous ARP packet and setting a default gateway MAC address to a sender hardware address of the received gratuitous ARP packet, comparing the at least one received priority value to a priority value local to the virtual router to determine which priority value is the highest, and electing the virtual router having the highest priority value as the master virtual router.
