"Our policy is to aggressively enforce our patents, with a proven track record of doing so," Rogers president and CEO Robert Wachob said.
"We learned of Rogers' concerns ... several months ago and we were doing everything in our power to demonstrate that our IS640 product cannot infringe their patents." said Isola Group chief executive Ray Sharpe, in a statement. "Rogers feigned cooperation with our attempts to resolve the issues amicably through showing that we do not infringe, I was disappointed when they served the complaint and issued a press release without the courtesy of giving us advance notice."
Isola USA Corp. has a patent
pending on the product in question.
The patents in question are U.S. Patent nos. 5,571,609 and 5,972,811,
which cover polybutadiene and polyisoprene thermoset laminates. Rogers
