Good luck with that one ! There are so many sevenesque designs out there both past and present, its pretty much a generic shape in its own right now. The Westfield situation proved a point and set a precedent, all that was back in the 1980's !. A few slight changes by Westfield and all was good, I don't think there are any like for like copies out there apart from those " pre litigation" cars prior to that case.

Do you mean the new owner of Caterham? The comments above are of relevance. I can't imagine anyone being able to prohibit the competitive manufacture of 'a 4 wheeled car with front cycle wings and a flat screen.' The Westfield case was a little different, being almost identical, and ISTR they used the word 'Seven', but I could be wrong.
