Making observations

Anyone can make observations on a request for an opinion. Observations need to be filed within 4 weeks of the date of the advertisement of the request on our website and must be confined to the issues raised in the request. An observer may file a reason as to why he thinks we should refuse a request.

Observations should preferably be sent to us by email. Our email address is opinions@ipo.gov.uk. A copy of the observations must also be sent to the person who filed the request, the patent owner and any exclusive licensee.

Extensions of time

The opinions process is quick - lasting no more than 3 months. Because of this time periods are short. Extensions of time may be requested, but very good reasons for the request will be required. Any extension is unlikely to be for more than a few days.

What if someone makes observations?

If someone makes observations, then within two weeks observations in reply may be made.

What if no-one makes observations?

If no-one makes observations, we will base the opinion on the documents we have already received.
