Abstract: A domain protected marks list (DPML) blocks domain name registrations that contain validly registered trademarks. When a request is received from a requestor for a DPML registration for a string comprising a trademark, it is verified to ensure the validity of the trademark and to further ensure that a prior block on the string does not already exist in one or more registries. Upon the verification, a DPML block is registered across the registries which do not comprise a domain name that corresponds to the string. This prevents domain name registrations for the string within the registries by parties other than the requestor.

Abstract: A system and method are directed towards identifying advertisement keywords within a variety of content types, identifying similarity rankings of advertisements based on the keywords, and to the guiding of keyword purchases. In one embodiment, a search is performed based in part on defined selection criteria, and/or scheduling rules. Content that may include advertisements is processed to identify advertisement keywords. A similarity ranking of different advertisements based on keywords therein may be determined. The similarity rankings may be used, with keyword pricing data, to identify instances of keyword arbitrage, guide purchase of keywords, and to control traffic flow to and from advertisements to obtain a benefit from price differentials between what one keyword seller charges for a keyword and what a click buyer will, pay for traffic directed to advertisements with the same or related keyword.

Abstract: Enabling a user of a video chat application to a virtual video message answering machine to contextually provide a video message to at least one other user of the video chat application for play back if the user is unavailable. The video message can be arranged to be played when another user attempts to initiate a video communication session with the unavailable user or during an existing video chat session after the user becomes unavailable. Also, the user can choose one or more contexts for playing back a video message to one or more other users that are likely to be participants in a future video communication session. The other user is provided with a user interface that enables the other user to record a video message reply for subsequent playback by the unavailable user.
