Editorial Summary

AI-assisted editorial summary; not attorney-reviewed. Verify against the opinion itself before relying on any characterization of the holding.

Following a District of New Jersey jury verdict that claims 14 and 15 of Mondis's U.S. Patent No. 7,475,180 were not proven invalid and were infringed by LG, the district court denied LG's motion for judgment as a matter of law. The Federal Circuit reversed, holding claims 14 and 15 invalid for lack of an adequate written description. That holding mooted infringement as well as the remaining issues — including the damages retrial, the refusal to declare the case exceptional, enhancement, and interest — and LG was held entitled to entry of judgment in its favor.
