In the latest bit of DMCA lunacy, copyright guru David Nimmer turned me onto a case that his firm is defending, where a garage door opener company (The Chamberlain Group) has leveled a DMCA claim (among other claims) against the maker of universal garage door remotes (Skylink). Yet another case where the anti-circumvention provisions of the DMCA are being used to impede legitimate competition, similar to the Lexmark case. Not, I think, what Congress had in mind when enacting the DMCA.
