Truseal Files Patent Infringement Suit

October 9, 2008

Truseal Technologies Inc., the supplier of warm edge spacer systems for insulating glass, announced yesterday that it is pursing legal action, including a request for emergency relief, against a Chinese manufacturer of spacer systems. The action has been brought to protect Truseal’s intellectual property and to safeguard the quality of IG units produced in the marketplace, officials note. As a result of the emergency nature of this action, the court has temporarily barred sales, use and advertising of the alleged infringing spacer systems.

Truseal filed suit October 6, in U.S. District Court, District of Nevada–Las Vegas against Beijing Huali Architecture Decoration Co. Ltd. (doing business as Huali), Beijing, China. The suit alleges that HualiSeal has infringed on a Truseal patent for composite spacer/sealant products.  Huali sells the infringing spacer products under the name “EdgeMax Seal” and “HualiSeal.” Under the order issued by the court, Huali is now prohibited from selling, using, offering for sale, or advertising these products until the court makes a ruling on the merits, Truseal officials state.

“Truseal vigorously enforces its patents and trademarks throughout the world and takes all potential infringement matters seriously,” says August J. (Gus) Coppola, Truseal president. “More importantly, Truseal is taking this action to safeguard the industry against the mistaken use of inferior technologies that claim to offer the same level of quality and performance as Truseal’s spacer systems.”

In addition to the October 6 suit filed against HualiSeal, Truseal is also investigating a Texas-based distributor of HualiSeal products. The company will take appropriate action pending the results of that investigation, as it does with all instances in which its patents are infringed.

“The HualiSeal case is an unfortunate instance of a Chinese manufacturer attempting to capitalize on patented technology,” notes Coppola. “While insulating glass fabricators should beware of counterfeit products from overseas suppliers, this case is not representative of the majority of business performed in the region or the world. Truseal is actively engaged in conducting business in China and other countries, and we support efforts to increase business activities within these regions, as long as intellectual properties, including patents, are respected.”
