English Headnotes:

1. A linguistic error, a spelling mistake or any other inaccuracy in a patent claim can only be corrected by way of interpretation of the patent claim if the existence of an error and the precise way to correct it are sufficiently certain to the average skilled person on the basis of the patent claim, taking into account the description and the drawings and using common general knowledge. 2. The patent claim must be interpreted from the perspective of the person skilled in the art. The applicant’s assertions during the grant proceedings, and in particular the TBA’s endorsement thereof, can be seen as an indication of the view of the person skilled in the art at the filing date.
