Appeal No. 2001-1057
Application No. 08/741,470
For their part, appellants contend, at page 7 of the brief, that Anupam teaches
that a change in the URL being displayed in one user’s, i.e, the session leader’s, web
browser initiates the change to a new URL being displayed in the browser of other
collaborators, and that with regard to chat sessions, Anupam discloses only that the
users participating in the coordinated browsing session may concurrently establish chat
sessions with one another. While this may or may not be the case, it is unclear to us
how the instant claims preclude such teachings since appellants point to no claim

to a request originating from a chat session as recited in Claims 5, 21 and 37.” [brief-
page 8]. In fact, argue appellants, Anupam “does not disclose any operation being
performed in response to a chat session request” [brief-page 8].
We agree with the examiner that, in Anupam, when surrogates of collaborators’
computers receive a new URL during a chat session, each of the surrogates directs, or
requests, its respective browser to open the Hypertext Markup Language (“HTML”)

creator of the session may “request” a new URL while he/she is chatting with other
