Via Licensing Issues Patent Call for Power over Ethernet

Via Licensing Corporation issued a call for patents that are essential to the practice of Power over Ethernet (PoE). Via Licensing is seeking to identifying the owners of patents that are determined to be essential to the practice of the IEEE 802.3af standard and IEEE P802.3at draft standard. A patent is essential if it contains at least one independent claim that is necessarily infringed by the implementation or use of the standard.


PoE technology enables a system to transfer electrical power along with data to a wide range of remote devices, including IP telephones, wireless LAN access points, network cameras, network switches, embedded computers, and other devices. PoE uses standard twisted-pair cable on an Ethernet network to deliver power in situations where it is impractical or expensive to use a separate power source.
