D 2022 - The DII part: FEED, CLEAN, SPRAY
This year's D2 was a paper of 3 h 20 min (13:25 - 16:45 CET) and 55 marks. The paper had to be taken fully from the screen in Wiseflow - nothing was printable. The pdf of the paper could be viewed side-by-side with the editor, without annotation possibility; or in one or more separate tabs, with annotation possibility (note here). For the first time, no calendars were given with the exam paper, but candidates had to bring their own lists of Saturdays and Sundays and had to check EPO closure dates in the OJ (see here).
As usually, the paper required a careful analysis of a plurality of EP and PCT patent applications from the client (OTP) and another party (TOR). The various applications described and/or claimed one or more of:
a) a FEED machine with a feeding duct,b) a FEED machine with two feeding ducts,c) a CLEAN method,d) a SPRAY device, ande) a FEED machine with a SPRAY device.
