Licences of Right
This page explains the consequences of a UK patent (whether owned by you or someone else) being endorsed “licences of right”. This also applies to UK patents which have been obtained via a European patent application.
For some patents, the proprietor may choose to have the official register marked (or “endorsed”) “licences of right”. This means that, if anyone wants a licence under the patent, the proprietor must grant them one. This will be an ordinary, commercial licence, on terms agreed between the proprietor and the licensee. However, if they cannot agree terms, the matter can be referred to the UK Intellectual Property Office, who will then decide on fair terms for the licence.
The renewal fees payable are only half what they would be otherwise. This is the main advantage to you. Such an endorsement may also help to attract licensees by indicating your willingness to grant a licence.
If you have a patent which you wish to have endorsed “licences of right”, it is necessary to apply to the UK Intellectual Property Office. The UK Intellectual Property Office then checks that there is no obvious reason why this should not be done (primarily that you have not already given someone an exclusive licence). If there are no problems, the Register is duly marked. Once this has been effected, future UK Intellectual Property Office renewal fees on the patent are reduced by half. In addition, our service charge is also reduced.
If you apply to have the register of a patent marked “licences of right”, it takes at least ten days for this to take effect. Therefore it is sensible to apply at least one month before a renewal fee is due, to ensure that the fee will be payable at the lower rate. The cost (approximately £110 plus VAT per patent) of the procedure of getting the endorsement made is such that there will certainly not be any saving in the first year. But if the entry remains in force for many years there can be appreciable savings.
You may approach the proprietor of a patent marked “licences of right” for a licence. The terms (e.g. royalty rate, duration, etc.) of the licence are subject to the usual commercial negotiation, but may be decided by the UK Intellectual Property Office on application by the proprietor or potential licensee if an agreement cannot be reached.
