I was browsing through Bodum's 2009 catalogue and came across a redesign of the filter assembly on their French press. Look at page 10-11 of http://tinyurl.com/55779m
It says the whole filter can be lifted out with 'no coffee grounds left in the glass' and the filter can be opened at the bottom to 'release the grounds easily into the trash.
Did a quick google but couldn't find anything else on it.
