IPO Proceedings

Professional Service


The UK IPO offers an opinion service, allowing interested parties to ask a UK IPO Examiner to indicate whether a UK patent, or a European patent having effect in the UK, is valid and/or infringed by a particular act. The UK IPO aims to issue opinions within about 3 months, and the cost of requesting an opinion is relatively low. This means the opinion service provides a quick and low-cost means of obtaining an official view on the validity and/or infringement of a UK or European patent.

To request a UK IPO opinion, it is necessary to notify the UK IPO of the question on which an opinion is sought (validity or infringement), the requester’s position on that question, and the evidence upon which that position is based. The request will then be published by the UK IPO so third parties, including the patent proprietor (if the proprietor is not the party requesting the opinion), can file observations in reply within a 4-week period. The requester will then be notified of any observations filed and will be given a further 2-week period to file observations in response. The UK IPO will then issue its opinion shortly afterwards.

For those wishing not to disclose their identity to the patent proprietor, it is possible to remain anonymous by allowing us to request the opinion in our name.

Additionally, if a UK (or European) patent is found to be invalid by the Examiner and the UK IPO is sufficiently confident in this conclusion, the UK IPO may (at its discretion) revoke the UK patent (or the UK designation of a European patent), allowing costly revocation proceedings before the UK courts to be avoided.

Despite the clear value and advantages of the UK IPO opinion service, it is often overlooked, with fewer than 30 opinions typically being requested each year. We have direct experience of requesting UK IPO opinions and are happy to work with you to get an opinion on a patent you are interested.


UK IPO Hearings

Examination of a UK patent application may involve a hearing before a Hearing Officer at the UK IPO. Hearings may also be held at the UK IPO at the end of a trade mark opposition, and in cases where there is a dispute over ownership of and/or entitlement to a patent or patent application.

Whatever the reason for the hearing, it is vital to present and argue the best case carefully, clearly, and in close alignment with the most recent law and procedures. We can take these cases, presenting at the hearing ourselves and, importantly, knowing when at other times to work directly with specialist counsel.

We also provide pre-hearing advice on strategy, prospects, and costs to plan for all eventualities.
