FREDERICK, Md. -- SEI, Inc, a leader in inline telecommunications powering, has received a non-exclusive license to manufacture and market Power over Ethernet (PoE) solutions under U.S. patent number 6,476,608 from PowerDsine. This patent forms the basis of the IEEE 802.3af powering standard both for the powering algorithms inherent in the standard and also for the delivery of device power over the Ethernet in using the spare pair.

As part of the license agreement, SEI, is authorized to manufacture and sell Midspan PoE and related products utilizing the intellectual property referenced in the patent, both in the US and internationally. Additionally, this license extends to the further resale, installation, and use of the intellectual property in US patent number 6,476, 608 with SEI licensed products.

“It is vital that our distribution channel and end users understand the breadth and scope of the license in that they are now protected against any potential infringement suits in the deployment of the SEI Juice Box PoE units by a third party patent holder in this rapidly growing market,” said Martin Grolnic, President of SEI.

This patent 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 effecting legacy devices. The patent covers PoE Midspan products that connect to an Ethernet switch in order to PoE-enable an enterprise network.
