73 Comptroller’s power to revoke patents on his own initiative.U.K.
(1)If it appears to the comptroller that an invention for which a patent has been granted formed part of the state of the art by virtue only of section 2(3) above, he may on his own initiative by order revoke the patent, but shall not do so without giving the proprietor of the patent an opportunity of making any observations and of amending the specification of the patent so as to exclude any matter which formed part of the state of the art as aforesaid without contravening section 76 below.
[F1(2)If it appears to the comptroller that a patent under this Act and a European patent (UK) have been granted for the same invention having the same priority date, and that the applications for the patents were filed by the same applicant or his successor in title, he shall give the proprietor of the patent under this Act an opportunity of making observations and of amending the specification of the patent, and if the proprietor fails to satisfy the comptroller that there are not two patents in respect of the same invention, or to amend the specification so as to prevent there being two patents in respect of the same invention, the comptroller shall revoke the patent.
(3)The comptroller shall not take action under subsection (2) above before—
(a)the end of the period for filing an opposition to the European patent (UK) under the European Patent Convention, or
(b)if later, the date on which opposition proceedings are finally disposed of;
and he shall not then take any action if the decision is not to maintain the European patent or if it is amended so that there are not two patents in respect of the same invention.
(4)The comptroller shall not take action under subsection (2) above if the European patent (UK) has been surrendered under section 29(1) above before the date on which by virtue of section 25(1) above the patent under this Act is to be treated as having been granted or, if proceedings for the surrender of the European patent (UK) have been begun before that date, until those proceedings are finally disposed of; and he shall not then take any action if the decision is to accept the surrender of the European patent.]
