Our Firm does not provide U.S. patent maintenance fee payment services or foreign annuity fee payment services. There are a number of vendors who provide these services. You may wish to contact multiple vendors to compare services or pricing. We do not endorse or recommend any particular vendor and cannot accept any liability or responsibility for your choice of vendor or its services. If you so request, we would be happy to provide you with a list of vendors as a courtesy and for your convenience.
