Or perhaps not. Dan's views of what facts are obvious for patents are irrelevant to whether or not someone would want to challenge a patent-holder in a costly patent fight; my view are equally irrelevant. If Dan's views are correct, many developers who stayed away from implementing EC due to patent concerns would have now started using EC with his curve due to EC's positive properties (faster, less CPU intensive, smaller messages, and so on). A look at the market in the three years since Dan introduced Curve25519 will show that there has been essentially no significant increase. This does not mean that Dan's views of the patent are wrong; it shows that vendors are so risk-averse that his views (and my views...) are irrelevant to the market. --Paul Hoffman, Director --VPN Consortium _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
