Patents Act 1990

The respondent in proceedings under section 128 may apply, by way of counter‑claim, for relief to which the respondent would be entitled in separate proceedings for an infringement by the applicant of the patent to which the threats relate.

Where the respondent applies by way of counter‑claim, the applicant may, without making a separate application under Chapter 12, apply in the proceedings for the revocation of the patent.

The provisions of this Act relating to infringement proceedings apply, with the necessary changes, to a counter‑claim.

Infringement proceedings cannot be commenced in respect of an innovation patent unless the patent has first been certified (see subsection 120(1A)).

The provisions of this Act relating to proceedings under section 138 for the revocation of a patent apply, with the necessary changes, to an application under subsection (2).

Revocation proceedings under section 138 cannot be commenced in respect of an innovation patent unless the patent has first been certified (see subsection 138(1A)).
