How do I challenge a patent?

If you believe that a patent in Washington is being used in a way that violates your rights, you can challenge the patent in a process known as a patent reexamination. This process involves filing a written petition with the United States Patent and Trademark Office (USPTO) that includes information about why you believe the patent is invalid. If the USPTO determines your petition is valid and finds other evidence to support your challenge, then the USPTO will schedule an ex parte reexamination. During this process, a patent examiner will review any evidence and look at the prior art that you provided. If the examiner decides that the patent is invalid, then the patent will be canceled and the public record will be updated. On the other hand, if the examiner finds that your challenge is not valid, then you may have the opportunity to appeal the decision. An appeal would then be filed with the Board of Patent Appeals and Interferences. The board will review your evidence and determine if the patent should be canceled, upheld, or amended. Overall, challenging a patent is a complex process and it is important to ensure that all information is accurate and that you provide the necessary evidence to support your claim. If you believe your rights are being infringed upon, then seeking legal advice is highly recommended.
