Questions Presented

  1. Whether summary judgment is proper on the patent infringement and breach‑of‑contract claims
  2. Whether the liquidated‑damages provision of $250 per unit is enforceable
  3. Whether a permanent injunction should be issued

Holdings

  1. Summary judgment is appropriate because there is no genuine dispute of material fact and Bayer is entitled to judgment as a matter of law.
  2. The $250 per unit liquidated‑damages provision is enforceable as a reasonable forecast of damages under Missouri law.
  3. A permanent injunction is appropriate to enjoin Duffy from making, using, selling, or transferring the patented seed and from applying unapproved herbicides.

Key quotations

Summary judgment is appropriate where the movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law. (at 792)
The liquidated‑damages provision of $250 per unit is enforceable if the amount is a reasonable forecast of just compensation for the harm caused by the breach. (at *2)
A plaintiff seeking a permanent injunction must demonstrate irreparable injury, inadequacy of monetary damages, a balance of hardships favoring the plaintiff, and that the public interest is not disserved. (at 391)

Factual background
