For example, she can select a map location A by activating or clicking on the A icon. Once she selects the map location A, the map information communication interface 300 then highlights the map location A on the reviews section (e.g., search results area 306), displays the A icon on the interactive map display area 308, and displays more detail information about the map location A on the detail location information area 320...” [para 27, 28, 44]; and displaying the local chat page, comprising a chat view and a map view, as a response to a request of the local chat page “...The interactive map display area 204 presents a map showing the location of the meeting place such as a restaurant or shopping center. The interactive map display area 204 may also show approach roads or alternative meeting locations. The interactive map display area 204 includes user and buddy chat bubbles (e.g., buddy chat bubble 212 and user chat bubble 214) as explained below. The interactive map may be dynamically rendered, and furthermore, may be dynamically rendered to show a map area that is under discussion...” [para 39]; the map view is generated based on local map information corresponding to a query based on meta information of the local chat page “...The interactive map may be dynamically rendered, and furthermore, may be dynamically rendered to show a map area that is under discussion...the search area 311 the search term "San Francisco, Calif." is entered into a search field 314 and a search is initiated by activating or clicking on the search button 316...” [para 39, 44]; and the chat view is generated based on chat information linked with the local chat page “...The comment log area 206 (also referred as a chat log) lists the comments by the user and any buddies in a time sequential order, such as user comment 208 and buddy comment 210.

Claim Rejections - 35 USC § 103 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 (i.e., changing from AIA to pre-AIA ) 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. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claims 5, 10, and 17 are rejected under 35 U.S.C. 103 as being unpatentable over Churchill et al. (US 20090254840 A1) in view of Jones (US 20090106040 A1). Claims 5 and 17: Churchill et al. teaches an operating method of a server that provides an instant messaging service “...server...instant message...” [para 28-29] and a server that provides an instant messaging service, the server comprising a processor configured to (“...processing unit...”) [para 25], as in claims 1 and 12 above, further comprising, determining a chatroom mapped to the local chat page as the target chatroom “...The interactive map display area 204 includes user and buddy chat bubbles (e.g., buddy chat bubble 212 and user chat bubble 214) as explained below. The interactive map may be dynamically rendered, and furthermore, may be dynamically rendered to show a map area that is under discussion...The user chat bubble 214 is displayed on the interactive map display area 204 pointing to the location of interest on the map, as specified by the user. The user chat bubble 214 also includes a text bubble displaying the text entered by the user...” [FIGs 2, 3A, 3B illustrate chat records created for specific chats for specific locations; para 39-40]; and determining a chatroom, comprising local information corresponding to the local chat page as a keyword, as the target chatroom “...in the search area 311 the search term "San Francisco, Calif." is entered into a search field 314 and a search is initiated by activating or clicking on the search button 316. Jane is not familiar with the city, but Joseph is. Jane types in "Sushi" in the search window 312 to search the local information database 118, and selects one of the possible locations shown in the search results area 306...” [para 44]; but Churchill et al. does not teach, the determining the target chatroom comprises: determining the target chatroom based further on the chat participation history of a user account However, Jones teaches, “...Implicit preferences can be inferred by the present disclosure by analyzing current behavior and/or historical user behavior. Such user behavior can be dynamic, such as the locations where a user goes in real-time in a social interaction environment, or asynchronous, such as slowly-changing user profile information including, but not limited to, individuals' likes and/or dislikes, social network ties information, and other information...” [para 26]; Therefore, it would have been obvious to one of ordinary skill in the art at the time of applicants' filed invention to incorporate the teachings of Jones into that of Churchill et al. in order to further tailor chat results to a user’s interests. Jones’ teachings leverage a user’s chat and other history as part of a recommendation system that utilizes “...behavior...by the system of the present disclosure to infer that the user is searching for an available social interaction space that readily engages new users. Further, the type of chat channels already sampled in this manner by the user could be utilized to suggest preferences relating to the type and/or topic of chat channels that are best to recommend to the user...” [Jones para 26] thereby expanding the relevant map view results in Churchill et al. to be more relevant to the user’s desired input query. Claim 10: Churchill et al. teaches an operating method of a terminal configured to execute an instant messenger (“...FIG. 3A is an illustration of an exemplary map information communication interface 300, which shows how a map information communication interface might appear on a display of a client 102 device...comments chat log area 302...a comments chat log area 302, an interactive map display area 308,a chat bubble 330, a new map view 332, a chat number 334, and a chat history area 326...”) [FIGs 3A, 3B illustrate an interface on a client for instant messaging with a map view; para 42, 50], as in claim 8, but Churchill et al. does not teach, the requesting the local chat page comprises: requesting the local chat page through an interfacing object provided based on whether a position of the terminal corresponds to the local chat page However, Jones teaches, “...the user's state is monitored. The state could include information about the user's location and/or the user's engagement in an activity. This information could be acquired by monitoring the user's actions in an electronic communications system (such a chat channel), or by remotely monitoring the user's physical actions using sensors (e.g., using a door sensor for monitoring the number of individuals within a room, remotely monitoring the user's presence through tracking of cell phone signals, or other suitable type of remote sensing system/device, etc.). In step 56, the monitored state is stored in a user profile database 58...” [para 26]; Therefore, it would have been obvious to one of ordinary skill in the art at the time of applicants' filed invention to incorporate the teachings of Jones into that of Churchill et al. in order to further tailor chat results to a user’s interests. Jones’ teachings leverage a user’s location and other history as part of a recommendation system that “...analyzing current behavior and/or historical user behavior. Such user behavior can be dynamic, such as the locations where a user goes in real-time in a social interaction environment, or asynchronous...the type of chat channels already sampled in this manner by the user could be utilized to suggest preferences relating to the type and/or topic of chat channels that are best to recommend to the user...” [Jones para 26] thereby expanding the relevant map view results in Churchill et al. to be more relevant to the user “...if a user belongs to a social group that typically goes to football matches an implicit preference for places where football is seen or discussed could be inferred...” [Jones para 26]. Claims 7 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Churchill et al. (US 20090254840 A1) in view of Kwon (US 20230308406 A1). Claims 7 and 19: Churchill et al. teaches an operating method of a server that provides an instant messaging service “...server...instant message...” [para 28-29] and a server that provides an instant messaging service, the server comprising a processor configured to (“...processing unit...”) [para 25], as in claims 1 and 12 above, but Churchill et al. does not teach, the generating the chat view comprises at least one of: generating the chat view in which messages transmitted in a chatroom linked with the local chat page are sorted in order of the most recently transmitted messages and generating the chat view in which the messages transmitted in a chatroom linked with the local chat page are sorted in order of importance However, Kwon does teach, “...when there is a plurality of recent messages sent within a predetermined (or, alternatively, desired) time range, the processor 220 may select a portion of the recent messages based on ranking of the OpenChat chatroom and may display corresponding message information. If a plurality of OpenChat chatrooms is associated with the same metadata, that is, the same area, the processor 220 may select a recent message of an OpenChat chatroom with relatively high ranking and may provide the selected recent message as message information. If a plurality of recent messages is present in the same OpenChat chatroom, the processor 220 may select a most recently sent message or a message that includes a main keyword related to a subject or an area and may provide the selected message as message information...” [para 59]; “...A message that satisfies a predetermined (or, alternatively, desired) condition in consideration of a text length or a message type may be selected as an important message as a message highly likely to be a valid message in terms of information in addition to up-to-dateness of a message...determine message rankings based on at least one of information of a chatroom in which a message is sent such as the number of members of the chatroom in which the message is sent and message information such as correlation between the message and a corresponding area, a sender of the message, a time at which the message is sent, a message length, and/or the like, and then may configure and display the list of recent messages 1180...” [para 93-95]; Therefore, it would have been obvious to one of ordinary skill in the art at the time of applicants' filed invention to incorporate the teachings of Kwon into that of Churchill et al. in order to present a user with the most recent and most relevant messages. Kwon’s teachings provides for the prioritization of the most recent and most relevant messages for a user based on their query. This is advantageous as a modification to Churchill et al. due to the nature of large volumes of chat messages being posted and shown on the map view. Kwon would allow for the most recent and relevant messages to be displayed on the user client display as taught by Churchill et al., thereby focusing the chat that is most relevant to the user based on their query.
