Because Apple has been inspired by them, not out-right copied them.

Apple take ideas from Braun and put them into different contexts (products). Samsung have taken Apple’s ideas and put them into the exact same context (or so the argument goes).

Another reason: The Braun designs that Apple have been inspired by are decades old by this point. Most of the Braun products don’t have these designs anymore (Aside: IMHO I think they current design is inferior to a lot of their older stuff.)

EDIT: Removed something that I don’t think was accurate.

Vast majority of the "copies" that Apple is accusing Samsung of doing in the exhibits Apple has shown so far are in the UI.

I do not think Apple has grounds in accusing Samsung of Hardware "copying". Design is nothing but organised copying and perhaps a little improv as well.

"Apple take ideas from Braun and put them into different contexts" -> that nailed it.
