CONCORD, Mass., Sept. 2 /PRNewswire/ -- Starmet Corporation (Nasdaq: STMT)
announced today that it had received notification from the United States
Patent and Trademark Office of an Office Action issued in the reexamination of
Brush Wellman's United States Patent No. 5,642,773 rejecting all the claims of
the subject patent. Brush Wellman has two months within which to respond to
the USPO Office Action. The Office Action is in response to the Company's
request for reexamination filed January 22, 1998 and granted March 28, 1998.
On December 9, 1997, after Starmet refused a request for cross-licensing
of Starmet's patented Beralcast(R) technology, Brush Wellman, Inc. instituted
suit alleging that investment casting of beryllium aluminum alloys by the
Company and its subsidiaries infringed the Brush Wellman patent described
above. On July 30, 1998 the United States District Court in Massachusetts
dismissed this suit without prejudice.
Starmet Commercial Castings LLC and Starmet Aerocast LLC, wholly-owned
subsidiaries of Starmet Corporation, manufacture advanced metal products for
government, aerospace and commercial applications using Starmet's patented
Beralcast(R) alloys and related patented and proprietary technology.
Starmet's products are produced by a variety of techniques, including
investment and permanent mold casting techniques. Its Beralcast(R) beryllium
aluminum alloys are 22% lighter and provide more than 300% greater stiffness
than aluminum. The material is ideally suited to certain demanding commercial
and aerospace applications.
