TUC Found to Infringe Isola Patents


Reading time ( words)

Isola Group announced today that a jury in the U.S. District Court for District of Arizona found that Taiwan Union Technology Corporation (TUC) had directly and indirectly infringed key patents held by its U.S.-based subsidiary, ISOLA USA Corp. The products found to infringe were TUC’s TU-872 laminate and prepreg products. The jury also unanimously found that Isola’s patents were valid and that TUC’s infringement was willful.

Pursuant to the verdict, the jury awarded Isola damages of $11.5 million for lost profits and reasonable royalty damages. The jury’s unanimous finding of willful infringement also means the Court has discretion to treble the damages awarded to Isola, and to award attorney’s fees and costs to the company.  

“We are extremely pleased with the jury’s verdict,” stated Jeff McCreary, Isola’s President and CEO. “The jury’s verdict is the culmination of more than three years of litigation by Isola. It reaffirms the strength of our patents and the company’s commitment to protecting and defending our intellectual property.”

The Isola patents at issue in the case were United States Patent Nos. 6,509,414 (“Epoxy Resin, Styrene-Maleic Anhydride Copolymer and Co-Crosslinking Agent”) and 8,022,140 (“Copolymer of Styrene and Maleic Anhydride Comprising an Epoxy Resin Composition and A Co-Cross-Linking Agent”).

While there are many Chinese companies now selling in the United States, I wanted to find one in Taiwan that is penetrating the U.S. market. I was delighted to come across EISO Enterprise Co. Ltd., a printed circuit board fabricator located in Taiwan. I know that the American companies are usually looking for PCB global partners in countries other than China, which made my conversation with Gary (Jung Kun) Chien all the more interesting, especially when he shared his thoughts on the U.S-China trade wars.
