Microsoft loses appeal of Enfish case at CAFC
From the decision:
Enfish, LLC owns U.S. Patent Nos. 6,151,604 and
6,163,775, which describe and claim methods and apparatuses
for storing and retrieving data using assertedly
improved database techniques. In September 2013,
Microsoft Corp. filed five petitions for inter partes review
of the ’604 and ’775 patents. After instituting review
based on those petitions, the Patent Trial and Appeal
Board concluded, in five final written decisions, that
some, but not all, of the challenged claims were unpatentable.
Microsoft and Enfish cross-appeal from selected
adverse portions of the Board’s decisions. We affirm.
