ALEXANDRIA, Va., Feb. 5, 2013

ALEXANDRIA, Va., Feb. 5, 2013 /PRNewswire/ -- The global law firm Fish &
Richardson has filed a patent infringement lawsuit in a Virginia federal court
on behalf of Rembrandt Social Media LP based on claims that Facebook Inc.
(NASDAQ: FB) and Add This Inc. used two Rembrandt patents without permission
to help build the world's largest social media web site.

"We believe Rembrandt's patents represent an important foundation of social
media as we know it, and we expect a judge and jury to reach the same
conclusion based on the evidence," says attorney Tom Melsheimer, counsel for
Rembrandt and managing principal of Fish & Richardson's Dallas office.

Rembrandt Social Media, an affiliate of Rembrandt IP Management LLC, filed the
lawsuit Feb. 5, 2013, in the U.S. District Court for the Eastern District of
Virginia. The lawsuit says Menlo Park, Calif.-based Facebook has infringed two
Rembrandt patents, U.S. Patent No. 6,415,316 and No. 6,289,362. Vienna,
Va.-based social media company Add This Inc. is accused of infringing the '362
patent. Both patents originally were issued to inventor "Jos" van der Meer
more than 10 years ago.
