Nov 20 Microsoft Corp filed a lawsuit
against Acacia Research Corp on Wednesday, charging
that Acacia broke a contract to license various smartphone and
mobile computing technologies to Microsoft.
The lawsuit, filed under seal in New York federal court,
follows a number of patent infringement lawsuits brought by
Acacia subsidiaries against Microsoft in October in Texas,
Delaware and Illinois.
In 2010, Microsoft agreed to pay an Acacia subsidiary to
license a portfolio of patents related to smartphones and
tablets ultimately owned by Tokyo-based web browser firm Access
In October, various Acacia subsidiaries filed lawsuits
against Microsoft, charging that the software company had
infringed more than a dozen patents.
Microsoft's lawsuit is a response to those actions, but
further details were unavailable as the lawsuit was sealed.
"Acacia's lawsuits are the worst kind of abusive litigation
behavior, attempting to extract payment based on litigation
tactics and not the value of its patents," said David Howard,
Microsoft's deputy general counsel, in an emailed statement.
A representative for Acacia did not immediately return a
call seeking comment.
The case is Microsoft Corp vs. Acacia Research Corp,
13-8275, U.S. District Court, Southern District of New York.
