The Arrow design is like Setpoint's in so far as it has seats on the outsides of the track, sure, but I doubt there's enough similarities for it to infringe on Seizmic's patents. First of all, from what we know, the Arrows don't "race" -- they're connected, aren't they? Also, I mean, Arrow's spin, for god's sake. If you ask me, that's enough difference right there, not to mention the track is completely different.
And if Arrow had started work on their new idea before Setpoint released plans for Seizmic and applied for the patent, wouldn't that justify it all?
