  How long will my patent last?
 


It depends. If you file your patent application today, your patent (if issued) will expire 20 years from the earliest U.S. filing date (excluding provisional applications). For applications that were pending on June 8, 1995, and for patents that were still in force on June 8, 1995, the patent term is 17 years from the issue date or 20 years from the earliest U.S. filing date, whichever is longer. The above assumes that all maintenance fees are timely paid and no terminal disclaimers were filed. U.S. design patents do not require maintenance fees, and expire 14 years from issuance.

Of course, there are often specific exceptions to the above. If you have any questions or wish to discuss how this may impact your company, please contact an attorney at Wood Phillips.
