KOHLER, Wis. -

The Kohler Co. has been ordered to pay $9.6 million to a marine engine and generator manufacturer in Massachusetts for infringing on two of its patents.

A jury in U.S. District Court in Boston found Kohler willfully infringed on patents owned by the Westerbeke Corp. which cover components that reduce exhaust emissions in its generators.

Kohler spokesman Todd Weber told The Sheboygan Press the technology used in Westerbeke's generators is "well known and in the public domain."

Weber says the company will ask the court to modify the jury's verdict.

Court records say jurors found that Westerbeke was due royalties worth 13.5 percent of Kohler's gross sales on its marine generators.
