it (4) without authorization in a way that (5) infringes rights protected by the Copyright Act due to a product created, advertised, or provided by the defendant Skylink. Once the plaintiff proves those five they must also prove that the defendant trafficked in a product which was (i) designed or produced primarily for circumvention; (ii) made available despite only limited commercial significance other than circumvention; or (iii) marketed for use in circumvention of the controlling technological measure. Chamberlain never claimed that Skylink infringed its copyrights or contributed to third-party infringement nor did it show that its users were unauthorized to use the product. As Chamberlain failed to show the fourth and fifth requirements to prove their claim, the Federal Circuit affirmed the District Court's grant of summary judgment to Skylink, writing, Chamberlain, however, has failed to show not only the requisite lack of authorization, but also the necessary fifth element of its claim, the critical nexus between access and protection. Chamberlain neither alleged copyright infringement nor explained how the access provided by the Model 39 transmitter facilitates the infringement of any right that the Copyright Act protects. There can therefore be no reasonable relationship between the access that homeowners gain to Chamberlain's copyrighted software when using Skylink's Model 39 transmitter and the protections that the Copyright Act grants to Chamberlain.
