In their long running battle, Mirror Worlds managed to obtain a $625 million verdict against Apple for infringement of U.S. Patent No. 6,006,227 (the " '227 Patent ") but Apple had the verdict vacated on appeal.
Under the terms of the agreement, Apple will receive a fully paid up non-exclusive license to the '227 Patent for its full term, which expired in 2016, along with certain rights to other patents in Network-1's portfolio. Network-1 will receive $25 million from Apple for the settlement and fully paid up license.
The '227 Patent was among 9 patents and 5 pending patent applications acquired by Network-1, through MWT, from Mirror Worlds, LLC on May 21, 2013. The '227 Patent entitled "Document Stream Operating System" relates to methods that enable unified search, indexing, displaying and archiving of documents in a computer system. The inventions described in the '227 Patent resulted from the work done by Yale University computer scientist, Professor David Gelernter, and his then graduate student, Dr. Eric Freeman, in the mid-1990s.
