1/ The Bow wings respecting  Diamond White’s Intellectual Property rights have a concave trailing edge, and bear a Certificate of Authenticity on one of their tips.
2/ The wings having a concave trailing edge when they are flying, seen from above, but which don’t bear a Certificate of Authenticity are probably infringing wings. The manufacturers, distributors, sellers and owners of such wings are likely to be prosecuted.
3/ The true hybrid wings have a straight or convex trailing edge when the kite is flying, viewed from above. They don’t fall under the “concave trailing edge”  patent but possibly under  other Diamond White’s patents.
