One case that has cast some light on co-ownership of trade marks in Singapore is Ng Chu Chong (trading as Grand Am Fashion Enterprise) v Ng Swee Choon & Ors (Suit No 1108 of 2001/E). Here the plaintiff and his sister, the first defendant, entered into a partnership called Grand Am Fashion Enterprise (Grand Am) to manufacture and sell fashion apparel under the trademark, McBlue. The trademark was created by the first defendant for the partnership and was registered in their joint names, trading as Grand Am. Subsequently, the first defendant withdrew from the partnership due to an impending bankruptcy but continued to work for the plaintiff as an employee. The plaintiff thereafter discovered that another partnership belonging to the first defendant's sister-in-law, named GA Fashion Apparel (GA) was marketing goods bearing the McBlue trade mark. The plaintiff brought an action against the defendants for trade mark infringement and applied for permanent injunction. The first defendant argued that she was entitled as a joint proprietor to authorize GA to purchase and deal with goods bearing the McBlue trade mark.
