Summary

You cannot get money for patent infringement that happened more than six years before you file a lawsuit or a counterclaim, unless another law says otherwise. If you sue the United States for using your patented invention, up to six years of time between when the agency got your written claim for payment and when the agency mailed you a denial notice does not count toward that six-year limit.

Except as otherwise provided by law, no recovery shall be had for any infringement committed more than six years prior to the filing of the complaint or counterclaim for infringement in the action. In the case of claims against the United States Government for use of a patented invention, the period before bringing suit, up to six years, between the date of receipt of a written claim for compensation by the department or agency of the Government having authority to settle such claim, and the date of mailing by the Government of a notice to the claimant that his claim has been denied shall not be counted as part of the period referred to in the preceding paragraph.
