| Headnote: | 1. Claims have to be clear for the sake of legal certainty (Nos. 2.2 to 2.4). 2. Since, in the absence of any unambiguous reference point, a relative term such as "lower alkyl" in the field of organic chemistry does not have a generally accepted meaning with respect to its maximum number of carbon atoms, such a term is ambiguous and therefore not suitable for clearly defining the subject-matter for which protection is sought in a claim which is directed to a group of organic compounds per se (No. 2.8). | ||||||||
| Relevant legal provisions: |
|
||||||||
| Keywords: | Clarity of claims for compounds per se Meaning of 'lower alkyl' unclear |
