Patent affirms technology leadership, spurs additional infringement litigation

Troy, Mich. – April 2, 2009 - ilumisys, Inc., developer and producer of next-generation solid-state lighting technology, announces on behalf of its parent company Altair Engineering, that Patent No. 7,510,299 was issued by the United States Patent and Trademark Office, thus adding to ilumisys’ foundational patent portfolio for the replacement of fluorescent tubes with light-emitting diodes (LEDs).

With the backing of Altair, its majority owner, ilumisys has a deep and substantial investment in research and development that includes more than 30 patent applications filed to date.
