Difficulty: Moderately Challenging
Things You’ll Need:
Step1
Know that there is no "patent infringement" board within any of the world's patent offices. Patent infringement is not within their spheres of influence. Infringement is essentially a private matter that must be handled through legal channels.
Step2
Contact a patent attorney or litigation attorney as soon as you note what you believe to be an infringement of your patent.
Step3
Understand that many patent suits can cost hundreds of thousands of dollars and take 2 to 3 years to settle. If your business does not have in-house counsel that can pursue litigation for you, consider asking an attorney to take your case on contingency.
Step4
Work with your patent attorney to bring the lawsuit to federal district court, which is the judicial level for patent-infringement cases. You must bring a suit within 6 years of the date of infringement. You may also need to defend the validity of your patent, which means you should gather any evidence that proves your original patent application is true and correct.
