Headnote
1. Observations submitted as filed after the "adjournment" of
the oral proceedings, which means the closing of the debate (in
French "prononcer la clôture des débats" and in German "die
sachliche Debatte für beendet erklären") are disregarded by the
Board unless it reopens the debate. The reopening depends on the
Board's discretion (point 1 of the Reasons).
2. A product which can be envisaged as such with all the
characteristics determining its identity including its
properties in use, i.e. an otherwise obvious entity, may become
non-obvious and claimable as such, if there is no known way or
applicable (analogy) method in the art to make it and the
claimed methods for its preparation are the first to achieve
this and do so in an inventive manner (point 5 of the reasons).
