Sidense To Prove Kilopass Patent Invalid

Company taking actions to prove invalidity of Kilopass 1T patent infringement assertions

Ottawa, Canada – May 23, 2010 - Sidense Corp., a leading developer of Logic Non-Volatile Memory (LNVM) OTP IP cores, has announced it intends to prove that the only patent asserted against it by Kilopass Technology, Inc. in the United States District Court for the Northern District of California on May 14, 2010, is invalid.

“Last week Kilopass filed in the US a complaint alleging Sidense is violating only one of their 1T patents, U.S. patent-6,940,751.  We are absolutely convinced there is no infringement,” stated Sidense Corp. CEO Xerxes Wania.  “Sidense, being an intellectual property provider itself, fully respects the intellectual property of others.  We are confident that no products offered by Sidense, or their methods of operation, fall within the scope of the claims of this patent.  Furthermore, we believe the asserted patent is invalid and unenforceable and will undertake necessary actions to prove it,” he added.

Mr. Wania further commented that Sidense’s innovation has been confirmed by multiple patent offices and foundries worldwide by constantly growing patent portfolio and industry wide acceptance of Sidense technology. With superior OTP technology, Sidense is confident that none of their products or methods of operation violate Kilopass’ intellectual property rights.
