Section 38: Effect of transfer of patent under section 37

Property in patents and applications, and registration.

  1. (1) Where an order is made under section 37 above that a patent shall be transferred from any person or persons (the old proprietor or proprietors) to one or more persons (whether or not including an old proprietor), then, except in a case falling within subsection (2) below, any licences or other rights granted or created by the old proprietor or proprietors shall, subject to section 33 above and to the provisions of the order, continue in force and be treated as granted by the person or persons to whom the patent is ordered to be transferred (the new proprietor or proprietors).

(2) Where an order is so made that a patent shall be transferred from the old proprietor or proprietors to one or more persons none of whom was an old proprietor (on the ground that the patent was granted to a person not entitled to be granted the patent), any licences or other rights in or under the patent shall, subject to the provisions of the order and subsection (3) below, lapse on the registration of that person or those persons as the new proprietor or proprietors of the patent.

(3) Where an order is so made that a patent shall be transferred as mentioned in subsection (2) above or that a person other than an old proprietor may make a new application for a patent and before the reference of the question under that section resulting in the making of any such order is registered, the old proprietor or proprietors or a licensee of the patent, acting in good faith, worked the invention in question in the United Kingdom or made effective and serious preparations to do so, the old proprietor or proprietors or the licensee shall, on making a request to the new proprietor or proprietors or, as the case may be, the new applicant within the prescribed period, be entitled to be granted a licence (but not an exclusive licence) to continue working or, as the case may be, to work the invention, so far as it is the subject of the new application.

(4) Any such licence shall be granted for a reasonable period and on reasonable terms.

(5) The new proprietor or proprietors of the patent or, as the case may be, the new applicant or any person claiming that he is entitled to be granted any such licence may refer to the comptroller the question whether that person is so entitled and whether any such period is or terms are reasonable, and the comptroller shall determine the question and may, if he considers it appropriate, order the grant of such a licence.
