Sun Electric Pte Ltd v Sunseap Group Pte Ltd

The High Court has original jurisdiction to revoke a patent only where revocation is sought by way of counterclaim in patent infringement proceedings (or in a declaration-of-non-infringement action), and not in free-standing/independent revocation proceedings, which must instead be brought before the Registrar of Patents. NOTE: the corpus 'existing_principle' for this id (winding up on the just and equitable ground / quasi-partnership) is WRONG - [2019] SGCA 4 / [2019] 1 SLR 645 is a PATENT REVOCATION JURISDICTION case (captioned Sunseap Group Pte Ltd v Sun Electric Pte Ltd on appeal), not a winding-up case.
