Catchwords:
|
|
Substantiation of an allegation that something is common general
knowledge is only required if this is challenged by another
party or the EPO (reasons 8.1) - Information has usually not
become common general knowledge because it was published in any
particular handbook or textbook, but rather it appears in
handbooks or textbooks because it was already common knowledge,
thus such a publication is evidence both that the information is
known and that it is common general knowledge (reasons 8.2).
