Seattle-based Modumetal Inc. has reached an agreement with Toronto-based Integran Technologies Inc. to end litigation in a patent dispute.

The companies “came to an agreement regarding Modumetal’s research and commercial activities relating to its nanolaminate technology,” according to a joint statement.

Terms of the agreement were confidential.

5 Patents at Issue

The settlement followed a patent infringement lawsuit that Integran filed in October 2010 against Modumetal in U.S. District Court in Seattle. The lawsuit included claims related to five patents, including some coating-related, owned and controlled by Integran.

Integran’s products include Nanovate NS, a nanocrystalline metal coating that protects carbon composites from impact and erosion.

Modumetal, founded in 2006, uses nanotechnology to develop new metals. The company is currently working on corrosion-resistant coatings for the oil and gas industry (for refinery and power plant equipment and pipelines) as well as cars, airplanes and military vehicles.

Integran is a global developer of advanced metallurgical nano-technologies, with more than 100 patents dealing with the structure, composition, processing and application of its materials.

Coatings Technologies

The claims against Modumetal involved five patents dating to 1994.

Two patents relate to fine-grained metallic coatings, which Integran says are “significantly harder and stronger than conventional coatings of the same chemical composition.”

One is a patent for a polymeric material partially coated with a fine-grained metallic material that is lightweight, strong and ductile, for aerospace and other applications.

Two relate to a process for producing nanocrystalline materials, which can be used for wear-resistant coatings and other applications.
