The patent was valid, but not infringed

Foster J has ruled that Bitech’s patent for an apparatus that simulates log flames or coal fire in electric or gas fired domestic room heaters is valid, but not infringed.

An essential feature of the patent was that the simulated flames resulted from reflected light, however, the alleged infringements used directly projected light, not reflected light and consequently did not infringe.

The novelty attack failed because the relevant prior art did not possess all the features claimed. The attack on obviousness failed because s 7(3) was not available – the complete specification was filed before the 1990 Act came into force and so the Alphapharm rules were all that was relevant.

Of potentially greater interest, if there had been infringement, Foster J would have found the importer and retailer (Bunnings) were engaged in a common design.

Somewhat bizarrely, on of the respondents denied it had imported the allegedly infringing products, but led no evidence on the point. As a result, Foster J has foreshadowed some consequences in costs for putting the applicant to proof on this point.
