Wyoming Law Against Bad Faith Patent Claims

Last scannedOct 18, 2026, 2:19 AM

In one sentence

This law prohibits making dishonest claims that others are infringing on patents and allows people harmed by these claims to sue for damages.

What it does

  • Prohibits making bad faith assertions of patent infringement.
  • Lists factors courts may consider to determine if a claim was made in bad faith, such as sending demand letters that lack specific patent details or threatening lawsuits that cannot be legally taken.
  • Lists factors that may show a claim was not made in bad faith, such as having made a substantial investment in the patent or being the inventor.
  • Allows people harmed by bad faith claims to sue in court for equitable relief, damages, costs, and attorney fees.
  • Allows courts to award exemplary damages of $50,000 or three times the total of damages, costs, and fees, whichever is greater.
  • Allows the state attorney general to enforce the law and seek injunctive relief or restitution for violations.

Who it affects

  • People or companies that send demand letters or threaten lawsuits about patent infringement.
  • Businesses or individuals who receive these patent infringement claims or are threatened with lawsuits.
  • Courts that decide if a patent claim was made in bad faith.
  • The state attorney general and district attorneys who can enforce the law.

Limits and unknowns

  • The law does not apply to patent owners notifying others of their rights, seeking reasonable compensation, or licensing patents.
  • The law does not apply to demand letters sent by patent owners actively using the patent in business or by universities and technology transfer organizations.
  • The specific determination of 'bad faith' is made by courts based on the listed factors, not by a single fixed rule.
