Facts:

The parties are both limited liability companies. Sometime in 1989 the plaintiff/respondent initiated a trading venture with an Italian company to manufacture grinding stones for the washing of terrazzo floors. The plaintiff/respondent adopted the trade mark ‘Super Rocket’ for the grinding stones which it registered in Nigeria under No. 51136 in class 19 with effect from 10th October, 1991 and the trade mark was inscribed on all the grinding stones ordered and supplied to the plaintiff. The plaintiff had in the course of the trading venture sold substantial quantities of ‘Super Rocket’ grinding stones all over Nigeria and had acquired substantial reputation and good will in the trade mark.
