Clause 29

Notwithstanding section 27, a registered trade mark is not infringed by the use of the trade mark in relation to goods which have been put on the market, whether in Singapore or outside Singapore, under that trade mark by the proprietor of the registered trade mark or with his express or implied consent (conditional or otherwise).

Subsection (1) does not apply where the condition of the goods has been changed or impaired after they have been put on the market, and the use of the registered trade mark in relation to those goods is detrimental to the distinctive character or repute of the registered trade mark.
