AMESBURY — A local manufacturer specializing in door and window components has sued a New York-based company, saying that it stole its idea for a window-lock mechanism and then selling it as its own invention.
Amesbury Group, on South Hunt Road, filed the claim against The Caldwell Manufacturing Company of Rochester, N.Y., on March 5 at the United States District Court in Boston.
In addition to seeking an immediate halt to the production and sale of a locking balance shoe and system for a pivotable window, Amesbury Group is looking to be awarded an unknown amount of money in damages.
Amesbury Group's attorney, Douglas Kline of Goodwin Proctor in Boston, did not return a phone call seeking information on a possible monetary award or what led to the discovery of the alleged patent infringement.
According to the complaint, the U.S. Patent and Trademark Office issued two patents to Stewart Uken, Gary Newman and Lawrence VerSteeg of the Amesbury Group for the locking balance shoe first in 2005 and then in 2007.
It was discovered later that The Caldwell Manufacturing Group began marketing a similar product, using ideas from the two patents as part of the manufacturing process, according to the complaint.
"Amesbury is without an adequate remedy at law, because Caldwell's infringement will irreparably harm Amesbury unless Caldwell is enjoined by the court from the actions complained of herein," the complaint reads.
The Amesbury Group was purchased by Lupus Capital of London in 1981. In 1985, The Amesbury Group, known then as Amesbury Industries, invented a type of foam weather seal that came to define the company's Amesbury location. In January, The Amesbury Group opened its newest production facility in Covington, Ga., extending its capabilities to even more parts of the United States.
