Gemfarm Investments (Pty) Ltd v Trans Hex Group Ltd and Another ([P] I 445 of 2005) [2009] NAHC 134 (7 April 2009)

Case summary

The plaintiff claimed that it was patentee and registered proprietor of an invention for the "method of, and apparatus for, underwater mining of mineral deposits known as a "pebble jetting system.” The plaintiff alleged that the defendants infringed on its patent by using integers of its invention in another invention, resulting in financial loss to the plaintiff. The defence argued that the Patents and Designs Proclamation, No. 17 of 1923 upon which the plaintiff relied for the registration of its patent had been repealed by the South African Patents Act, No 37 of 1952 and was therefore no longer in force in Namibia and that the union Act in s18 of the proclamation was to become main legislative piece for patents.

The court therefore had to decide whether the Patent proclamation was still in force and determine the legitimacy of the granting of the patent and the meaning of Union Act in the proclamation.

The court found that that the provisions of the proclamation under which the patent in issue had been granted, were not repealed or amended by the 1952 Act and were valid by virtue of Article 140(1) of the Constitution. Secondly, that the extent to which the Union Act had been applied to the law of patents in the Territory stemmed from s.5 of the Proclamation and, although it applied the Union Act to a wide range of specified matters, it did not apply to applications for the granting of patents. The matter was dismissed with costs.
