| Headnote: | 1. The polymer product of a known chemical process is not new automatically as a result of the said process being modified. 2. If such a chemical product cannot be defined by structural characteristics (substance parameters) but only by its method of manufacture (process parameters), novelty can be established only if evidence is provided that modification of the process parameters results in other products. It is sufficient for this purpose if it is shown that distinct differences exist in the properties of the products. 3. This evidence may not include properties which cannot be due to the product's substance parameters (in this case, absence of monomer impurities with an unwanted odour). |
