Osmose grants patent licenses to Arch

A patent dispute between two suppliers of wood-preserving technologies has led to a licensing agreement. 

Griffin, Ga.-based Osmose has agreed to grant a worldwide license to Arch Treatment Technologies to practice under certain patents owned by Osmose. The patents cover the use of micronized wood preservatives, including the patent that was the subject of a previous dispute between the two companies.

Terms of the licensing agreement were not disclosed.

Arch Treatment Technologies is a subsidiary of Arch Chemicals.

Micronized wood preservatives are utilized to pressure-treat wood products commonly used in decks, fences, landscaping, agricultural, house framing and other general construction uses.

Both companies will continue to supply their portfolios of preservative products to consumers, contractors and builders, according to a release announcing the licensing agreement.
