In chemistry, the right approach to the definition of the invention is a particular challenge. For example, if a new compound can be characterized by a chemical formula, the claims should not only mention the new compound itself, but also all possible structural variants of the new compound. In cases where an exact structural definition of the compound is not possible, particularly in the polymer field, it is of crucial importance to find alternative ways of defining the compound such as by a set of parameters or other features, e.g. by a product-by-process definition, in order to achieve the justified scope of protection.

Our attorneys have long-standing know-how in this respect and a broad scientific background from our research work in industry and academic institutions. In complex cases such as opposition and infringement cases, we co-operate with university professors who specialize in the relevant scientific field. We also have access to several non-public databases, enabling us to carry out prior art and freedom-to-operate searches.
