In Zup v. Nash Manufacturing, ZUP filed suit, alleging contributory infringement and induced infringement of the patent-at-issue, trade secret misappropriation under Virginia law, and breach of contract.  Nash counterclaimed, seeking declaratory judgment as to non-infringement and invalidity… Prior art references aiming to overcome problems similar to those addressed by a patent can support a motivation to combine invalidating references, and for evidence of a long-felt but unresolved need to be considered, the need must be solved by an invention that is more than minimally different from the prior art… Judge Newman dissented, finding that the majority applied an incorrect analysis of the obviousness factors. In her view, the prior art provides no suggestion to make the specific modifications made by the patent-at-issue, and the only source of those modifications is judicial hindsight.
