A Boston court ruled in Blizzard's favor last week
against a lawsuit brought on by Worlds Inc.
(aka Worlds.com) that claimed the studio infringed on four patents that Worlds Inc. made in the mid-1990s.
This ruling is the latest development in a case that spans back to 2012, when Worlds Inc. filed the suit. The company claimed that Blizzard
violated patents that showed the invention of "a method for enabling a first user to interact with other users in a virtual space," among other items. A U.S. District Judge ruled that these patents are invalid because those inventions already existed prior to the filings.
This isn't Worlds' first attempt to sue an MMO studio over these allegations, as it went after (and lost to) NCsoft
and Linden Lab
several years ago.
