SAN FRANCISCO, USA: The legal diatribe between Fairchild and Power Integrations (PI) is back again.

Back in 2006, PI dismissed the suit filed against it by Fairchild and in 2010, Fairchild planned to appeal PI patent ruling. While the two companies have been into this legal battle, each accusing the other, both of them have been found to infringe patents.

A federal jury found that, PI infringes a U.S. patent held by Fairchild and found that Fairchild infringes two patents held by PI. According to Fairchild, The jury in the District court in Delaware found that PI products infringe the patent, U.S. No. 7,259,972. Some of those PI products included some LinkSwitch II and LinkSwitch-CV products.

At the same time, the jury also found that, some of Fairchild's pulse width modulation (PWM) controllers infringe on two patents held by Power Integrations, reports Dylan McGrath of EETimes.

Fairchild said, the jury found that Fairchild did not infringe on two other patents Power Integrations had asserted against the company.

The litigation began in 2008 and the verdict concluded the first phase of the trial. The second phase will determine the wilfulness and damages in the case and it may occur after appeals of the first phase, said Fairchild.

Tom Yang, senior vice president of technology for Fairchild’s Power Conversion, Industrial and Automotive products division, who is the inventor of the patent found to be infringed, said, "I am delighted and gratified that the jury has affirmed the validity of our patents.”

There are three other patent lawsuits in which PI and Fairchild are involved. Fairchild is asserting patent infringement claims against PI in China. The two companies are awaiting a ruling from the U.S. Court of Appeals for the Federal Circuit in their appeal of a 2004 lawsuit. In a case scheduled for trial, next year in Federal court in San Francisco, the companies are assessing patent infringement claims against each other.
