A news release issued today by Brinks Hofer Gilson & Lione (Brinks) reveals the U.S. Patent and Trademark Office (USPTO) has granted the firmâs requests for reexamination of Trading Technologies International, Inc.âs (TTâs) U.S. Patent Nos. 6,766,304 and 6,772,132. The alleged prior art cited in the Brinks reexamination request does not present any new arguments. In early 2005, the Court considered this same prior art and found that TT showed a very strong likelihood of success on the issue of validity. Statistically, the overwhelming majority of reexamination requests are granted and TT is confident that the validity of its patents will be upheld.
