Seoul Semiconductor signs patent license with US inventor

The Korean LED manufacturer has signed a license agreement to avoid a complaint filed with the International Trade Commission.

LED manufacturer Seoul Semiconductor signed a license agreement with Professor Gertrude Neumark Rothschild in early April 2008. Rothschild, formerly with Columbia University, filed a complaint in the United States International Trade Commission (US ITC) against 30 companies on February 19, 2008 (see Patent complaint targets LED makers, consumer electronics industry).

Several other LED makers have settled legal actions filed by Rothschild against them, although in these case there was no specific reference to a licensing agreement.

"With the license agreement, Seoul Semiconductor is able to provide unrestricted sales of LED products in the U.S. market, providing further assurance to our vendors and customers,” according to a spokesperson for Seoul Semiconductor. Of course, the term "unrestricted" only refers specifically to the small piece of intellectual property owned by Rothschild.

The spokesperson further added that “Seoul Semiconductor is a strong proponent of protecting its intellectual property rights and respects the intellectual property right of other companies. This is evidenced by our recent successes in protecting our IP rights in number of lawsuits in Korea and by us signing a patent license agreement with Itswell Co., Ltd. just last month.” (See Seoul wins LED patent case against AOT, licenses Itswell).

Seoul Semiconductor says that it possesses approximately 2,000 LED-related patents worldwide, and has signed numerous license agreements and strategic partnership with universities, laboratories and companies in the LED industry.
