PowerDsine has settled its litigation with System Engineering International Inc. As part of the settlement, PowerDsine granted SEI a license to use its U.S. patent number 6,476,608 in connection with the manufacture and sale of midspan PoE products.

PowerDsine had commenced an action before the Federal District Court for the Southern District of New York alleging that certain products produced and/or sold by SEI infringe PowerDsine’s midspan technology patent. Following settlement discussions, the two companies reached an amicable settlement.

“We are very pleased to reach an amicable settlement with SEI,” said Simon Kahn, PowerDsine’s director of intellectual property. “This settlement is part of PowerDsine’s intellectual property strategy of providing licenses to companies that want to take an active role in the Power over Ethernet market.”

PowerDsine’s U.S. patent 6,476,608 addresses an Ethernet LAN, in which “power enabled” elements are detected so that current limited power can be distributed safely via spare pairs of the data Ethernet cabling infrastructure to those elements without affecting legacy devices. The patent covers PoE midspan products that connect to an Ethernet switch in order to PoE-enable an enterprise network.

PowerDsine has been granted similar patents in China, Taiwan, Singapore, Australia, New Zealand and South Africa. These patents protect the same claims covered by the foregoing U.S. patent. In addition, PowerDsine has patent applications covering this technology pending in five countries and Europe.
