This was a patent infringement case related to technology "related to patient slippage within the context of the Trendelenburg position for surgery—when using a viscoelastic foam." Justin Blok was the defendants’ damages expert. The plaintiffs sought to exclude Blok’s testimony on the reasonable royalty because they contended he used unreliable and irrelevant documents to support his opinion. The defendants argued, and the court agreed, that Blok’s opinions go to the weight and not to the admissibility of his opinions.
