Form 23

Details

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)

Do not ask for uncertified and certified copies on a single form. For certified copies you should also use a separate form for each patent application or patent.

All Intellectual Property Office fee bearing forms should be filed with the appropriate fee.
