The U.S. Court of Appeals for the Federal Circuit on Friday affirmed a grant of summary judgment of noninfringement in a patent case involving fluorescence detection technology. The decision upholds a ruling from the U.S. District Court for the Northern District of California.
The appeal was brought by the Regents of the University of Michigan, who had sued over alleged infringement. The Federal Circuit agreed with the lower court's claim construction, which was the basis for finding no infringement.
The ruling highlights the importance of claim construction in patent litigation, as the case was resolved on those grounds without a trial on the merits.
