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 The response filed 4/22/2026 was received and considered. Claims 1-23 are pending. Response to Arguments Applicant's arguments filed 4/22/2026 have been fully considered but they are not fully persuasive. Applicant’s remarks (p. 8, 1) discuss amendments to the claims addressing the rejections under 35 U.S.C. §112(b). In view of the amendments, the rejections are withdrawn. Applicant’s remarks (p. 9, 2h) suggest that the specification supports the term “secure chat portal (SCP)”, citing the specification at ¶81 (“The Secure Chat Portal 930 is web accessible on the Public Cloud 900 between any combinations of the user-1 Endpoint 5 devices, a VR goggle 961, a smart phone 963, a Tesla dashboard 964, a pair of AR glasses 965 and user-2 Endpoint devices, a VR goggle 951, a smart phone 953, a Tesla dashboard 954, a pair of AR glasses 955 through the network connection 982 and 981 respectively”), Fig. 9 (“Secure Chat Portal 930”) and that “Wikipedia dated 2007/11/19” discussing secure messaging and a definition of “portal” as a website or page on the Internet enabling access to information to an interested group of people. Applicant argues that these sources together would enable a skilled artisan to deduce the metes and bounds of the claimed element. The Examiner respectfully disagrees. The skill level of an artisan in the art in question is generally high and the prior art comprises separate examples of implementations of, for example, chat programs, P2P communication, authentication, etc. However, the original disclosure provides no specific description of how the claimed secure chat portal is constructed or operated, no protocols or standards used to achieve the claimed SCP, no protocols or standards by which the claimed P2P communication channel “through the SCP” is achieved, no authentication mechanisms used for signing in with the claimed client credential and no examples of existing implementations of those elements such that an ordinarily skilled artisan could make and use the claimed SCP in the context of the claimed invention without undue experimentation. Further, the Examiner respectfully maintains that while “Secure messaging” and web sites acting as a portal to additional information as concepts were generally taught by Wikipedia and known in the art, such a teaching was not sufficient to enable the claimed SCP to be made and used in the manner claimed as the scope of the claimed “secure chat portal (SCP)” is indetermined. The Examiner suggests clarifying, using the claim language, the scope of the claimed secure chat portal (SCP) such that the metes and bounds are clear to the reader. Further, the Examiner suggests clarifying how the peer-to-peer (P2P) communication channel is established “between the host and the at least one invitee through the SCP”. Applicant’s remarks (p. 10, 2i) argue the publication US20230106531A1 teaches “Virtual Network Router”, which provides a sufficient definition of the term being a term of art. Initially, the Examiner notes that the cited publication is not assigned to the assignee of the instant application and is not within the same family as the instant application. Regarding the term being a term of art, the Examiner respectfully disagrees. The Examiner appreciates that the term “virtual LAN” was known in the art prior to the invention as a mechanism for organizing network traffic. However, the original disclosure provides no specific description of how the claimed “virtual LAN router” is constructed or operated, does not teach the nature of the linking (“linked”) with the claimed “LAN mode secure chatroom” and “virtual machine server” such that the linking could have been used by a skilled artisan to deduce the metes and bounds of the terms “virtual LAN router” or “LAN mode secure chatroom” and no description of how the claimed element functions within the claimed invention such that an ordinarily skilled artisan could make and use the recited virtual LAN router within the invention as a whole without undue experimentation. Applicant’s remarks (p. 10, 2j) argue that the disclosure supports the term “linked” because the claimed elements are intangible elements linked by a virtual or real path. The argument is persuasive. Applicant’s remarks (p. 10, 2i) argue that (1) “Paragraph [0081] of the present application recites "The LAN mode Secure Chat is conducted via the two smart VPN tunnels through connections 984, 988, and 982 and 20 then teleported to a Virtual Private Metaverse-1 950 underneath its virtual LAN 904. It is therefore private and secure. What happens in secure chat, stays in secure chat.” (specification at ¶81) and (2) publication US20160364368A1 teaches “chat room” and that by combining “LAN mode secure chat” and “chatroom”, a skilled artisan would have been able to implement “LAN mode secure chatroom”. Initially, the Examiner notes that the cited publication is not assigned to the assignee of the instant application and is not within the same family as the instant application. The Examiner appreciates the plain and ordinary definition of “chatroom”, local area network (“LAN”) and “secure”, as it applies to the art in question and appreciates the relatively high level of skill and predictability in the art. However, the Examiner respectfully maintains that the disclosure’s recitation that the “LAN mode Secure Chatroom mechanism” is insufficient in describing the metes and bounds of the claimed “LAN mode Secure Chatroom” to said ordinarily skilled artisan, so as to enable the artisan to make and use the recited LAN mode Secure Chatroom in the manner claimed without undue experimentation. The Examiner suggests clarification in the claim language describing the nature and construction of the LAN mode secure chatroom. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1-23 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the enablement requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to enable one skilled in the art to which it pertains, or with which it is most nearly connected, to make and/or use the invention. Regarding claims 1, 9 and 21, the claims recite “secure chat portal” “(SCP)”. However, the specification does not describe the SCP such that a skilled artisan could make or use the invention. The disclosure does not enable one of ordinary skill in the art to practice the invention without the structure and functionality of the claimed secure chat portal. Claims 2-8, 10-20 and 22-23 inherit the deficiency. Regarding claims 1, 9 and 21, the claims recite “virtual LAN router”. However, the specification does not describe the virtual LAN router such that a skilled artisan could make or use the invention. The disclosure does not enable one of ordinary skill in the art to practice the invention without the structure and functionality of the claimed virtual LAN router. Claims 2-8, 10-20 and 22-23 inherit the deficiency. Regarding claims 1, 9 and 21, the claims recite “LAN mode secure chatroom”. However, the specification does not describe the LAN mode secure chatroom such that a skilled artisan could make or use the invention. The disclosure does not enable one of ordinary skill in the art to practice the invention without the structure and functionality of a LAN mode secure chatroom. Claims 2-8, 10-20 and 22-23 inherit the deficiency. Prior Art The closest prior art: “Peer-to-peer communication in web browsers using WebRTC A detailed overview of WebRTC and what security and network concerns exists” (Jakobsson, Christer) teaches a host (peer) establishing a peer-to-peer (P2P) communication channel between the host and the at least one invitee (another peer) through the SCP (STUN server provides IP and port and a first peer passes connection information to another peer via a signaling server, p. 5, §2.4);the host launching a secure application (peers exchange multimedia information, p. 7, §2.6); the host starting the LAN mode secure application (peers exchange multimedia information, p. 7, §2.6) ; the at least one invitee launching a secure chat application and the at least one invitee signing in the LAN mode secure application with the chatroom credential (peers exchange multimedia information, p. 7, §2.6). US 20130191896 A1 (Adderly; Darryl M. et al.) teaches method for establishing a secure collaboration in a public cloud network (conferencing via clout, Fig. 4, including conferencing system 78, scheduler 80, clients 76 and 90),the public cloud network comprising a an internet ecosystem comprising a secure chat portal (SCP) (conferencing system 78, Fig. 4, N virtual machine servers (VMS) linked to the SCP (virtualization layer uses virtual servers as part of the cloud computing system, ¶53, ¶24), the method comprising: a host sending a client credential (login information sent in a meeting invitation,¶66, ¶¶76-77; credential is required for client to establish a connection, ¶66) to the at least one invitee (sent to output devices, ¶76) through a VMS of the N virtual machine servers (virtualization layer uses virtual servers as part of the cloud computing system, ¶53, ¶24); the host and the at least one invitee signing in with the client credential to the SCP (login information sent in a meeting invitation ,¶66, ¶¶76-77; credential is required for client to establish a connection, ¶66); the host launching a secure chat application (cloud system comprises cloud computing nodes 10, including application programs for their functionality, ¶48); the host starting the LAN mode secure chatroom with a chatroom credential of the LAN mode secure chatroom (start of presentation, ¶67; meeting data includes URL/credential, ¶74); the host sending the chatroom credential to the at least one invitee (login information sent in a meeting invitation, (chatroom identification and chatroom passcode) ¶¶76-77; see also ¶114); the at least one invitee launching a secure chat application (cloud system comprises cloud computing nodes 10, including application programs for their functionality, ¶48); the at least one invitee signing in the LAN mode secure chatroom with the chatroom credential (providing credential for verification, ¶113; URL, credentials and password information is set for an output device/client and a particular meeting, ¶74); and the host authenticating the at least one invitee with the chatroom credential; wherein N is a natural number (verifying credential, ¶113). “Cisco WebEx Meetings” (Verizon) teaches clients logging (using a client credential) into a chat portal (Webex meetings application SignIn, p. 1) and teaches joining a meeting by providing a meeting number to search for a meeting (p. 3, step 2), which can require a password (chatroom credential) to join (p. 5, step 6). US 20230216947 A1 (BERNARDI; ROBERT) teaches establishing a WebRTC P2P connection between peers (Figs. 21-23 and ¶¶451-455). US 8375421 B1 (Shigapov; Andrey et al.) teaches establishing virtual meetings, including a host requesting a virtual meeting room and credentials, the host providing the credentials to a recipient (col. 2, line 50 – col. 3, line 10; see Figs. 1-2 for architecture), where the meeting participants can establish a connection with the virtual meeting room server with using a VPN and virtual IP addresses (col. 6, lines 5-13). Shigapov teaches a public cloud network comprising: a host (master device, col. 2, lines 61-63)); at least one invitee (guest client devices, col. 3, lines 1-2); a public cloud comprising an internet ecosystem comprising: at least one secure chat portal (SCP) (virtual meeting room server, Fig. 2) linked to the host and the at least one invitee (VRS linked to client devices, Fig. 2);; and at least one virtual private metaverse (VPM) comprising: at least one virtual local area network (LAN) router (virtual meeting room server, Fig. 2); and at least one LAN mode secure chatroom linked to the virtual LAN router (virtual meeting room linked to virtual meeting room server, Fig. 2); a peer-to-peer (P2P) communication channel is established between the host and the at least one invitee through the SCP (peer to peer communications through VRS, col. 3, lines 31-36), the host launches a secure chat application, the host starts the LAN mode secure chatroom with a chatroom credential of the LAN mode secure chatroom (master client device requests a virtual meeting room, col. 2, lines 61-63), the host sends the chatroom credential to the at least one invitee (col. 2, line 66 – col. 3, line 2), the at least one invitee launches a secure chat application (guest device receives virtual meeting room client, col. 3, lines 2-5), the at least one invitee signs in the LAN mode secure chatroom with the chatroom credential (devices use credential to authenticate to VRS, col. 3, lines 2-5), and the host authenticates the at least one invitee with the chatroom credential (secure communications are established, col. 3, lines 6-9). US 20210075748 A1 (Agarwal; Pavan et al.) teaches a chat server implemented on a virtual machine server (¶32). US 20230308446 A1 (Tong; Dan et al.) teaches a conferencing server implemented on a virtual machine server (¶37). US 20150092603 A1 (Aguayo; Dan et al.) teaches using virtual LAN routers with a VPN to partition local area networks into VLANs (¶68, ¶¶72-73). Potential Allowable Subject Matter Claims 1-23, as best understood in view of the rejections under 35 U.S.C. 112(a), could be allowable if clarified to overcome the rejections. Particularly, it is suggested that some combination of the structure and functionality of the claimed components be recited so as to clarify the metes and bounds of each element of the claims. Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action.
