Schedule 1paragraph 9, sub-paragraph (4) Section 9 – Co-ownership
60.This section amends section 36(3) in order to clarify the rights of co-owners in respect of amendment and revocation of their patent, in the circumstances in which they make no agreement between themselves on these matters. Unless the co-owners have agreed otherwise, they must act jointly if they wish the patent to be amended. Thus one co-owner cannot act unilaterally to amend the patent without the agreement of the others. Similarly, unless the co-owners agree that it should be possible, one co-owner cannot seek revocation of the patent against the wishes of the others.
