T 1809/17 - Essential features and Art. 100(b)

 Key points

  • This is an opposition appeal. The opponent argues that claim 1 is insufficiently disclosed by not specifying all essential features.
  • The  Board considers claim 1 to be sufficiently disclosed: “Maßgeblich ist hierbei nicht, ob der unabhängige Anspruch alle wesentlichen Merkmale definiert, sondern ob die gesamte Patentschrift dem Fachmann wenigstens ein gangbares Ausführungsbeispiel aufzeigt, wie die in Anspruch 1 definierte Erfindung umsetzbar ist.” (emphasis added)
  • The patent teaches at least one way for “Umsetzung der Erfindung” (German original) so that the invention is sufficiently disclosed, Article 100(b) EPC.
