This morning the Federal Circuit issued one nonprecedential opinion in a patent case. Here is the introduction.
Mirror Worlds Technologies, LLC v. Facebook, Inc. (Nonprecedential)
Mirror Worlds Technologies, LLC owns U.S. Patent Nos. 6,006,227, 7,865,538, and 8,255,439, which describe and claim systems and methods for presenting and storing data in time-ordered streams on a computer system. Mirror Worlds brought the present action against Facebook, Inc., alleging that Facebook’s making, selling, using, and other actions involving various Facebook systems infringed the ’227, ’538, and ’439 patents. Facebook filed a motion for summary judgment of non-infringement before discovery ended, and the district court granted it. Mirror Worlds appeals.
We agree with Mirror Worlds that the district court’s judgment must be reversed. The district court relied for its decision on an erroneous conclusion that there is no genuine dispute about certain facts. Facebook defends the summary judgment on alternative grounds. We will not affirm on those alternative grounds. We reverse the court’s judgment and remand for further proceedings.
