In a statement, TUC demanded Isola USA Corp. immediately retract its allegations and related legal procedures and “stop harassing TUC customers and interested companies at once.”
 
Last week, Isola alleged that TUC product numbers TU-662 and TU-752 infringe China patent no. 123529. 
 
“TUC believes that Isola’s allegation of patent infringement is groundless,” TUC said in a press statement. Extensive testing show the composition of TU-662 and TU-752 laminates by TUC and outside experts and scholars are outside of the scope of the patent, the company asserted. On advice of legal counsel, TUC declined to disclose the name of the outside testing facilities, the company told PCD&F.
 
The company further stated it would will take “all available legal actions” to protect it from damages to its business and reputation. 
 
Isola also filed claims against ITEQ; that company has not publicly responded.
