Relating to creating a private cause of action for bad faith claims of patent infringement.

HB 5543 creates a legal remedy for people or businesses using patented products who face patent infringement claims made in bad faith. It allows courts to order the party making the false claim to post a bond covering the defendant's legal costs - up to $500,000 - to protect against frivolous lawsuits. The bill directly affects patent holders who file questionable infringement claims and the end users who get sued. It becomes effective September 1, 2025, if passed.
