Chemists think in formulas. For most chemists, drawing a structure is easier than naming it. Of course, this language of formulas is also used in the field of patents.
Compounds explicitly mentioned in the claim or in the examples are registered as defined structures by e.g. CAS, Thomson or Elsevier. A special feature of patents, however, are the generically defined claims.
These are often referred to as “Markush structures” after Eugene Markush, the first inventor who claimed a generic definition for a group of possible substances in a US patent in 1923.
For a professional search it is necessary to search for defined chemical compounds as well as for generically defined claims. The latter searches are not exactly easy and require an experienced searcher!
Effective searches for chemical information can only be performed in appropriately designed databases, since the recording of the chemical structures is very time-consuming.
We offer you professional search in relevant chemical databases such as Registry, REAXYSFILESub and MARPAT. Such very specific structural searches are absolutely necessary at various points in the development process!
Such very specific structural searches are absolutely necessary at various points in the development process!
It is certainly much cheaper to perform a solid search at the beginning of the development than to find out later when filing a patent application that the in-house development is already known or falls under a generic claim of the competition.
