Office Action

§103
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 . 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 final rejection. Because 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. The submission identified in the request has been entered. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. Claims 1, 6, 7, 8, 9, and 22 are rejected under 35 U.S.C. 103 as being unpatentable over US 20160006800 (Summers) in view of EP 2391087 (Burch). Regarding claim 22, Summers teaches or suggests a system comprising: a first endpoint device including one or more processors (¶ 38) and storing executable instructions configured to manipulate a computer system (abs., ¶¶ 68, 69) to: detect, by a first endpoint device, a second endpoint device (abs., ¶¶ 68, 69); transmit, by the first endpoint device, a system services message to the second endpoint device wherein the available system services available to the second endpoint device comprise system services operating on the second endpoint device (¶¶ 74, 88); receive, by the first endpoint device from the second endpoint device, in response to the resolution query, an available resolution for at least one system service available to the second endpoint device (¶¶ 76, 90); and execute one or more applications associated with a functionality, wherein executing the one or more applications comprises transmitting, from the first endpoint device to the second endpoint device, data implementing the functionality using at least one available system service from the list of available system services based on use of the communication protocol and the addressable location of the available resolution (¶ 92). Summers does not expressly disclose but Burch teaches or suggests the available resolution comprises an addressable location usable by a communication protocol (¶ 2). It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to combine Summers’ system and Burch’s addresses because a user may not know the correct address. Regarding claim 6, the aforementioned combination teaches or suggests and receiving, by the first endpoint device from the second endpoint device, resolution service data associated with the second endpoint device (Burch ¶ 2). The teachings and suggestions of the references would have been combined for the same rationale as explained for claim 22. Regarding claim 7, Summers teaches or suggests receiving, from the second endpoint device, a list of available system services available to the second endpoint device via a communication protocol of a plurality of communication protocols based on the resolution service data (¶¶ 110, 121). Regarding claims 1, 8, and 9, the aforementioned combination teaches or suggests the limitations of the claims as explained supra, mutatis mutandis. Claims 2 and 11 are rejected under 35 U.S.C. 103 as being unpatentable over US 20160006800 (Summers) in view of EP 2391087 (Burch) further in view of US 20110113142 (Rangegowda). Summers does not expressly disclose but Rangegowda teaches or suggests receiving, by the first endpoint device, a plurality of available resolutions from the second endpoint device based on at least the one available system service from the list of available system services, and wherein the available resolution is one of the plurality of available resolutions (¶ 43 available protocols). It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to combine Summers’ system, Burch’s addresses, and Rangegowda‘s plurality to accommodate different versions of IP addressing. Claims 3, 10, and 20 are rejected under 35 U.S.C. 103 as being unpatentable over US 20160006800 (Summers) in view of EP 2391087 (Burch) further in view of US 20130185647 (Yu). Regarding claims 3, and 10, Summers does not expressly disclose but Yu teaches or suggests receiving, by the first endpoint device, a plurality of available resolutions from the second endpoint device based on at least the one available system service from the list of available system services, and wherein the available resolution is one of the plurality of available resolutions (¶ 43 available protocols). It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to combine Summers’ system, Burch’s addresses, and Rangegowda‘s plurality to accommodate different versions of IP addressing. Regarding claim 20, Summers does not expressly disclose but Yu teaches or suggests the second endpoint device is proximate to the first endpoint device (Yu ¶ 48 range, ¶ 49 WLAN proximity). It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to combine Summers’ system, Burch’s addresses, and Yu’s proximity because devices may be near each other. Claims 4 and 5 are rejected under 35 U.S.C. 103 as being unpatentable over US 20160006800 (Summers) in view of EP 2391087 (Burch) further in view of US 20160066048 (Ashbrook) and US 20140189117 (Niimura). Regarding claim 4, Summers does not expressly disclose but Ashbrook teaches or suggests receiving, by the first endpoint device from the second endpoint device, a second list of available system services associated with a third endpoint device communicatively coupled to the second endpoint device (claims 32-33). It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to combine Summers’ system, Burch’s addresses, and Ashbrook’s second list to gain access to further services. Summers does not expressly disclose but Niimura teaches or suggests requesting, by the first endpoint device from the second endpoint device, a second available resolution for a system service from the second list of available system services (¶¶ 61-62). It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to combine Summers’ system, Burch’s addresses, Ashbrook’s second list, and Niimura’s requesting to be able to use a different version of IP. Regarding claim 5, the latter combination teaches or suggests transmitting, by the first endpoint device to the third endpoint device, data implementing the functionality using the system service from the second list of available system services based on the second available resolution (Ashbrook claims 32-33, Niimura ¶¶ 61-62). The teachings and suggestions of the references would have been combined for the same rationale as explained for claim 5. Claim 12 is rejected under 35 U.S.C. 103 as being unpatentable over US 20160006800 (Summers) in view of EP 2391087 (Burch) further in view of US 20170324790 (Li). Summers does not expressly but Li teaches or suggests a detection protocol and a communications protocol (¶ 41). It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to combine Summers’ system, Burch’s addresses, and Li’s protocols so the second endpoint device is detected by a first communication protocol and the available resolution is received by a second communication protocol. A rationale to so would have been to combine the familiar elements from the references according to known methods to yield the predictable result of using protocols. Claims 13-15 are rejected under 35 U.S.C. 103 as being unpatentable over US 20160006800 US 20160006800 (Summers) in view of EP 2391087 (Burch) further in view of US 20080256607 (Janedittakarn). Regarding claim 13, Summers does not expressly disclose but Janedittakarn teaches or suggests in response to detecting the second endpoint device, requesting, by the first endpoint device, access to a discovery service engine of the second endpoint device (¶¶ 36-37 and 52 request, 46 integral). It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to combine Summers’ system, Burch’s addresses, and Janedittakarn’s requesting for in response to detecting the second endpoint device, requesting, by the first endpoint device, access to a discovery service engine of the second endpoint device. A rationale to so would have been to combine the familiar elements from the references according to known methods to yield the predictable result of preceding access with a request therefor. Claim 13 is rejected under 35 U.S.C. 103 as being unpatentable over US 20160006800 (Summers) in view of EP 2391087 (Burch) further in view of US 20080256607 (Janedittakarn). Summers does not expressly disclose but Janedittakarn teaches or suggests in response to detecting the second endpoint device, requesting, by the first endpoint device, access to a discovery service engine of the second endpoint device (¶¶ 36-37 and 52 request, 46 integral). It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to combine Summers’ system, Burch’s addresses, and Janedittakarn’s requesting to combine the familiar elements from the references according to known methods to yield the predictable result of preceding access with a request therefor. Claims 14-15 are rejected under 35 U.S.C. 103 as being unpatentable over US 20160006800 US 20160006800 (Summers) in view of EP 2391087 (Burch) further in view of US 20030123419 (Ragnekar) and US 20080256607 (Janedittakarn). Regarding claim 14, Summers does not expressly disclose but Ragnekar teaches or suggests receiving, at the first endpoint device, a resolution service data associated with the discovery service engine of the second endpoint device (¶ 34 available protocols); and accessing the discovery service engine of the second endpoint device based on the resolution service data (¶ 37 and 54 access). It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to combine Summers’ system, Burch’s addresses, Janedittakarn’s requesting, and Ragnekar’s resolution to discover engines Regarding claim 15, the latter combination teaches or suggests accessing the discovery service engine of the second endpoint device by a communication protocol of a plurality of communication protocols based on the resolution service data (Ragnekar ¶ 37 and 54 access). Claims 16 and 17 are rejected under 35 U.S.C. 103 as being unpatentable over US 20160006800 (Summers) in view of EP 2391087 (Burch) further in view of US 20160066134 (Rybak). Regarding claim 16, Summers does not expressly disclose but Rybak teaches or suggests the one or more applications are configured to render one or more notifications ( ¶ 9). It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to combine Summers’ system, Burch’s addresses, and Rybak’s notification so the one or more applications are configured to render one or more notifications. A rationale to so would have been to combine the familiar elements from the references according to known methods to yield the predictable result of informing a user of something that needs to be known. Regarding claim 17, the latter combination teaches or suggests executing the one or more applications comprises rendering one or more notifications on a display electronically coupled to the second endpoint device (Id.). The teachings and suggestions of the references would have been combined for the same rationale as explained for claim 16. Claims 18 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over US 20160006800 (Summers) in view of EP 2391087 (Burch) further in view of US 20190028414 (Walker). Regarding claim 18, Summers does not expressly disclose but Walker teaches or suggests the first endpoint device has a first operating system and the second endpoint device has a second operating system distinct from the first operating system ( ¶ 54 different OSs). It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to combine Summers’ system, Burch’s addresses, and Walker’s OSs so the first endpoint device has a first operating system and the second endpoint device has a second operating system distinct from the first operating system. A rationale to so would have been to combine the familiar elements from the references according to known methods to yield the predictable result of taking advantages of the features of different OSs. Regarding claim 19, the latter combination teaches or suggests the second operating system has at least one different interface, language, memory management technique, communication protocol, encryption, or network stack from the first operating system (id. 54 different languages). The teachings and suggestions of the references would have been combined for the same rationale as explained for claim 19. Claim 21 is rejected under 35 U.S.C. 103 as being unpatentable over US 20160006800 (Summers) in view of EP 2391087 (Burch) further in view of US 20170153694 (Baldwin). Summers does not expressly disclose but Baldwin teaches or suggests the second endpoint device includes a device ID data of a third endpoint device (claim 1 third device identifier). It would have been obvious to a person of ordinary skill in the art, before the effective filing date of the claimed invention, to combine Summers’ system, Burch’s addresses,, and Baldwin’s identifier so the second endpoint device includes a device ID data of a third endpoint device. A rationale to so would have been to combine the familiar elements from the references according to known methods to yield the predictable result of one device being aware of another. Response to Arguments The arguments have been fully considered. The Examiner has withdrawn the prior rejections and instituted the aforementioned ones. Other Art The prior art made of record and not relied upon is considered pertinent to the instant disclosure. For example, US 20200204598 allows a communication session to be transferred between endpoints.
