Section 67: Proceedings for infringement by exclusive licensee

Sections (67.01 - 67.06) last updated: July 2010.


This section lays down the position of an exclusive licensee under a patent with regard to infringement of that patent. The exclusive licensee has the same right as the proprietor of the patent to bring infringement proceedings in respect of acts committed after the date of the licence (subsection (1)) and may be awarded damages or other relief by the court or the comptroller in respect of infringement of his rights as exclusive licensee (subsection (2)). The proprietor must be made a party to any such proceedings (subsection (3)).


In accordance with s.69, references in this section to a patent and the proprietor of a patent are to be respectively construed as including references to an application which has been published but not yet granted and the applicant.


For the applicability of s.67 in relation to European patents, see 60.02.

Section 67(1)
Subject to the provisions of this section, the holder of an exclusive licence under a patent shall have the same right as the proprietor of the patent to bring proceedings in respect of any infringement of the patent committed after the date of the licence; and references to the proprietor of the patent in the provisions of this Act relating to infringement shall be construed accordingly.


s.130(1) is also relevant

An exclusive licence is a licence from the proprietor of or applicant for a patent conferring on the licensee, or on him and persons authorised by him, to the exclusion of all other persons (including the proprietor or applicant), any right in respect of the invention to which the patent or application relates. Multiple exclusive licences may be granted under a single patent or application if those licences relate to distinct rights in respect of the invention (this fact was acknowledged in Courtauld’s Application [1956] RPC 208). For example, separate exclusive licences could be granted to different parties for the respective rights of manufacturing the invention and using the invention, or to confer the rights in different geographical areas.


In Morton-Norwich Products Inc and others v Intercen Ltd [1981] FSR 337 the Patents Court held that the corresponding provisions of the 1949 Act were to be intended to give a licensee, who has stepped into the shoes of the patentee so as to be able to exercise any right in respect of the invention for his own benefit to the exclusion of all others including the patentee, exactly the same right as the patentee would have had. It was held that there was no requirement for any particular document or form of grant as being necessary to constitute an exclusive licence and that the position was a mixed question of law and fact.


The consequences of non-registration of the licence on infringement proceedings are laid down by s.68.

Section 67(2)
In awarding damages or granting any other relief in any such proceedings the court or the comptroller shall take into consideration any loss suffered or likely to be suffered by the exclusive licensee as such as a result of the infringement, or, as the case may be, the profits derived from the infringement, so far as it constitutes an infringement of the rights of the exclusive licensee as such.
Section 67(3)
In any proceedings taken by an exclusive licensee by virtue of this section the proprietor of the patent shall be made a party to the proceedings, but if made a defendant or defender shall not be liable for any costs or expenses unless he enters an appearance and takes part in the proceedings.
