Narrative Opinion Summary
In this patent infringement case, Funai Electric Company, Ltd. pursued legal action against Daewoo Electronics Corp. and affiliates, alleging infringement of multiple patents, resulting in a jury finding of willful infringement of three patents. The case involved complex issues of claim construction, the doctrine of equivalents, and patent validity under 35 U.S.C. § 112. Daewoo contested the jury's verdict by filing a motion for judgment as a matter of law (JMOL) and a motion for a new trial, both of which were denied by the court. The court upheld the jury's damages award, which included both lost profits and reasonable royalty theories, despite Daewoo's challenges based on the marking requirement and the absence of non-infringing alternatives. The court granted Funai a permanent injunction, citing ongoing infringement concerns and rejecting Daewoo's claims of voluntary compliance. Funai's motions for enhanced damages and attorneys' fees were partially granted, with the court emphasizing Daewoo's willful infringement and litigation conduct. Ultimately, the court ordered both parties to confer on attorneys' fees and prejudgment interest calculations, setting deadlines for further submissions and hearings if necessary. The decision underscores the complexities involved in patent litigation, particularly in interpreting claim language and assessing damages.

Enhanced Damages under 35 U.S.C. § 284subscribe to see similar legal issues
Application: The court denied Funai's request for enhanced damages, finding insufficient evidence of egregious conduct by Daewoo.

Indefiniteness under 35 U.S.C. § 112subscribe to see similar legal issues
Application: The court addressed Daewoo's challenge to the indefiniteness of claims in the '538 patent, rejecting claims of ambiguity.
Reasoning: Daewoo contends that claims 1, 3, and 4 are indefinite for two reasons: the construction of 'series junction point' is grammatically incorrect, and the doctrine of claim differentiation indicates that the scope of claim 2 overlaps with claim 1.
