Headnote: If a product is required to manifest a particular property (in this case a highly fungicidal effect) under various conditions, the superiority of the invention will depend on whether or not that property is improved under all conditions liable to be encountered in practice and particularly under the various conditions evolved in order to test it (in this case exposure to water and wind). If comparative tests are cited in support of that superiority, it is their combined results that have to be considered. The decisive factor is whether the invention out-performs the substance used for comparison in the tests as a whole (in this case, results in the need to use a significantly lower concentration of the pollutant substance), even if the substance used for comparison proves better in one of the tests.
Relevant legal provisions:
European Patent Convention 1973 Art 56
Keywords: Inventive step
Basis of comparison for substantiating an improvement
Admissible comparison of values from different tests
Comparison of values from different tests
