JPSA succeeds in invalidating QMC’s Korean scribing and lift-off patents

Manchester, N.H. – JP Sercel Associates Inc. (JPSA), a manufacturer of laser micromachining systems for LED production, has announced that the Korean Intellectual Property Tribunal has ruled in favor of JPSA's claims, invalidating two of QMC’s Korean patents dealing with scribing and lift-off (LLO).

The invalidated Patents are No. 724540, “Laser Beam transmission system and method of the same and lift-off process method,” and No. 588459, “An adjustable laser beam delivery system and method for forming the same.” Patent No. 588459 was invalidated on June 23rd, 2010, and Patent No. 724540 on July 8th, 2010.

JPSA contended that QMC’s patent claims were invalid over various prior art references including JPSA’s Korean Patent No. 0849779, “Method for separating layers of material," and Korean Patent No. 790644, “System and method for cutting using a variable astigmatic focal beam spot."

“Prior to developing laser systems, QMC was a former Korean sales and service representative of JPSA; therefore, they had key information about our technology and methods," said JPSA chairman, Jeffrey Sercel. "We were surprised and disappointed to find QMC filing for patents that we already had Patents for. Despite our disappointment, we continue to invest valuable time and money to protect our highly advanced laser technology, and our years of experience and development work have resulted in JPSA’s strong market presence in scribing and LLO of LEDs.”

QMC has already appealed the invalidation decisions, but JPSA is confident that the Korean Patent Court will agree with the findings made by the Intellectual Property Tribunal on June 23rd and July 8th, 2010.
