On Thursdays the USPTO publishes new pending patent applications. Both of today's Spotlight applications address various aspects of DRM and copyright protection in mobile contexts. Assigned to NetBarrage (IL), the first application discloses a Peer to Peer file sharing mobile system with copyright protection. Assigned to Samsung, the second application discloses techniques for managing digital rights management contents in portable terminal.
The present invention relates a peer to peer system for enabling a mobile device user to legally search and only legally download content items by his mobile device, comprising: (a) a user software having a user interface at the mobile device for connecting to a peer to peer network, searching for a content item according to a user query, introducing the results to the user, and enabling a conditional downloading only upon ensuring payment for items that are found to be copyright protected; (b) an identification server for receiving identification information relating to a selected right protected item from said user software, searching for at least meta data and price corresponding to said item, and forwarding the found meta data and price to the user software; (c) a module within said user software for, upon receipt of said meta data and price, suspending the conditional downloading, prompting the user to appropriately pay at a billing server if the item is copyright protected, and resuming the download only upon clearing said payment; and (d) billing server for receiving payment from the user, and upon completion of same, sending payment clearance to said user software, which in turn resumes downloading of the item.
