Core Wireless Licensing S.A.R.L. v. Apple, Inc.

Core’s 143 patent recites a mobile station, such as a mobile telephone, that is connected to a cellular system or network. It is directed to means for sending packet data from the mobile station to the network using a selected channel. In prior art, the mobile station would send the network information about the data packet so that the network could make the channel selection decision. Selection by the network wastes system resources, because it requires the mobile station to send a message to the network regarding the data packet the mobile station wants to transmit, and then requires the network to make the channel selection decision. The 143 patent describes the mobile station, not the network, making the uplink channel selection decision; the network provides the mobile station with parameters that the mobile station applies in determining whether to use a dedicated channel or a common channel, which reduces “the signaling load associated with the allocation of packet data transfer” and “the delay associated with the starting of data transfer.” The Federal Circuit affirmed a verdict that Apple did not infringe, based on a holding that the claim requires that the mobile station “must have the capability to perform ‘channel selection,’ even if that capability was not used during the actual alleged performance of the claimed method.” View "Core Wireless Licensing S.A.R.L. v.
