PRESS RELEASE
April 6, 1999
Fairfax, Virginia--AAROFLEX, Inc. filed motions for summary judgment in the
Federal Court to invalidate four of the primary patents of 3D Systems, Inc.
The motions contend that that the patents are invalid because of the known
prior art in the industry and the doctrine of double patenting. A court in
Japan recently over turned many of the same 3D patent claims that AAROFLEX
seeks to invalidate in the US District Court.
History and a written paper trail clearly shows that long before 3D secured
its first license to produce stereolithography units the process had been
placed in the public domain. Many of the original claims licensed by 3D for
its first units were overturned during a reexamination requested by DuPont.
The Motions allege that 3D slipped these overturned claims into new patent
applications one-by-one. This procedure is called double patenting and is a
violation of the U.S. Patent Office rules and regulations.
If the motions are granted, 3D’s ability to limit competition by threatening
others with suits for patent infringement will be substantially reduced.
“Once the summary judgments are awarded AAROFLEX will move forward with
greater determination for producing the best line of machines in the market
with its patented features” Mr. Albert C. Young, Jr., the CEO of AAROFLEX
responded to questions about AAROFLEX’s future. “I wish to bring to the
market a new and revolutionary machine that I have designed to further
enhance our product line.”
