Detail

Do not use this form to either:

  • request to inspect a file at the office in Newport or London, (but please check with the office by telephone or letter in advance because it may take several days to make a file available in the Public Search Rooms)
  • request certified copies of European patent applications, (you can only get these from the European Patent Office)
