Polyform and Nudura File Patent Infringement Suit Against Airlite Plastics Co.'s Fox Blocks Products

TORONTO--(Marketwire - June 21, 2010) - Nudura Corporation today announced that it has filed a patent infringement lawsuit against Airlite Plastics Co. in the United States District Court for the Middle District of Georgia. Nudura's ICF products are produced in Columbus, GA by ICForm, Inc.

In the filing, Nudura (along with Polyform A.G.P. Inc. and Plastiques Cellulaires Polyform, Inc.) alleges that Airlite infringes claims that have issued from the United States Patent & Trademark Office after reexamination of the claims of United States Patent No. 6,401,419. The newly issued patent claims, set forth in detail in a certificate of correction issued by the Patent Office on March 23, 2010, were granted over prior art that was not before the patent examiner when the original claims of the '419 patent issued in June of 2002. The newly issued claims cover various aspects of the stackable construction panels and the reversible design of the recesses and projections that can be found in Polyform and Nudura's highly successful and innovative line of NUDURA® Insulated Concrete Form (ICF) products.

Polyform and Nudura seek injunctive relief against Airlite Plastics to prohibit the manufacture, sale, distribution, and use of Airlite Plastics' Fox Blocks line of ICF products in the United States. 

Polyform, A.G.P., Inc., through its subsidiary Plastiques Cellulaires Polyform Inc., manufactures the NUDURA® line of ICF products in Quebec and in the United States. Nudura Corporation is the exclusive distributor of NUDURA® ICF products in the United States and throughout the world. 

Polyform and Nudura are represented by Merchant & Gould, one of the largest law firms in the United States with an exclusive focus on the creation and enforcement of intellectual property rights. Merchant & Gould is based in Minneapolis, Minnesota and has nine offices, including one in Atlanta, GA.
