inward bars are just another example of the standard bar, which is the simply T style. designs like wing bars, slayers, crows, tanks etc are all unique, and yours is a blatant copy, you didn't think of that idea, you took it and made slight changes in the hope people wouldn't call you, pathetic, think of something new
also, you're right, there is virtually no way to make them noticeably different, and they aren't trying to, now if you exactly copied crows and made it public that you did in order to offer more of a market of them, that would be mildly respectable, but you tried to hide your unoriginality
