Headword: I. An amendment to a patent by the introduction of a "negative"
technical feature into a claim resulting in the exclusion of
certain embodiments is, regardless of the name "disclaimer",
none the less an amendment governed by Articles 123(2) and (3)
EPC (point 2.2 of the Reasons for the Decision).
II. The practice of permitting disclaimers having no support in
the application as filed to make a claimed subject-matter novel
by delimiting it against an accidental anticipation cannot be
maintained in the light of the Enlarged Board of Appeal's
opinion G 0002/98 (point 2.3 and 2.4 of the Reasons for the
Decision).
III. Any amendment of a claim not having support in the
application as filed and aiming at distancing the claimed
subject-matter further from the state of the art, in particular
by way of a disclaimer, contravenes Article 123(2) EPC (point
2.5 of the Reasons for the Decision). |
