Effect of non-registration on infringement proceedings

Where by virtue of a transaction, instrument or an event to which section 30 applies, a person becomes the owner or one of the owners or an exclusive licensee of a patent and the patent is subsequently infringed, the Court shall not award him damages or order that he be given an account of the profits in respect of such subsequent infringement occurring before the transaction, instrument or event is registered unless– (a) the transaction, instrument or event is registered within the period of six months beginning with its date; or 43 (b) the Court is satisfied that it was not practicable to register the transaction, instrument or event before the end of that period and that it was registered as soon as was practicable thereafter.
