Keywords: Normal and special meaning of terms used in patent documents
Novelty (yes)
Catchwords:

Terms used in patent documents should be given their normal meaning in the relevant art, unless the description gives the terms a special meaning. The patent document may be its own dictionary (T 523/00, T 311/93, neither published in the OJ EPO).

Thus, if a special meaning can be derived from the patent document, only this meaning is ultimately decisive.
