Mondis Technology Ltd. v. LG Electronics Inc., No. 20-1812 (Fed. Cir. 2021)
Annotate this Case
Limited is the assignee of the 180 patent, which is directed generally to a display unit configured to receive video signals from an external video source. Limited sued LG for patent infringement. After the district court granted Limited leave to join Hitachi as plaintiffs to address a standing challenge brought by LG, the case proceeded to trial. The jury found that the accused LG televisions infringed two claims of the patent, that the claims were not invalid, and that LG’s infringement was willful, and awarded Plaintiffs $45 million in damages.
In September 2019, the district court denied LG’s post-trial motions regarding infringement, invalidity, and willfulness but ordered further briefing on damages. On April 22, 2020, the district court granted LG’s motion for a new trial on damages. On May 8, 2020, LG filed a notice of interlocutory appeal, seeking to challenge the denials of LG’s post-trial motions regarding infringement, invalidity, and willfulness, all of which were decided in the September Order. LG also challenged the pretrial joinder decision, arguing that, without such joinder, Limited lacked statutory authority to bring suit. The Federal Circuit dismissed for lack of jurisdiction. LG’s notice of appeal was not filed within 30 days of the date at which the liability issues became final except for an accounting.
The court issued a subsequent related opinion or order on December 23, 2021.
