Of course, Brompton's fold isn't protected under any intellectual property rights, but they claimed the reason their knickers were in a twist because the unfolded profile with it's curved top tube - which the Oyama shares - was copyrighted as an iconic look.

Of course since, as coolio points out, the unprotected and superior fold isn't cloned, none of us here in the real world think Brompton will waste a farthing going after this bike for copyright infringement.
