In the table below we provide you with information about applications we have received to amend the specification of a patent under sections 27 and 75 before the court and the Office. The table also includes information about when you need to file an opposition if you wish to oppose the application to amend.
Where amendments have been filed electronically, you can obtain full details by selecting the patent number. If you are the patent owner(s), you should check these details carefully and inform us if there are any problems. Where amendments have been filed in paper form only, the symbol * appears in the table after the patent number.

You can obtain reasons for the amendments and full details of any amendments filed in paper form by contacting Litigation Section (telephone: +44 (0)1633 814334).
