Pre-Alice Finding of Validity Collaterally Estops Defendant From Challenging Validity Under 35 U.S.C. § 101

The court granted plaintiff's motion for summary judgment that defendant's challenge under 35 U.S.C. § 101 was barred by collateral estoppel because a jury found the patent-in-suit valid in the parties' prior action. "While the Federal Circuit has yet to address squarely whether multiple theories of invalidity constitute 'different' issues for collateral estoppel purposes, the majority of courts that have considered the question view patent validity as a single issue. . . . [E]ven if [Alice Corp. Pty. v. CLS Bank Int’l, 134 S. Ct. 2347 (2014)] had constituted a change in the law, [defendant] does not explain how pre-Alice law would have precluded [it] from bringing a Section 101 defense. . . . There is no evidence that a Section 101 defense was completely unavailable to [defendant] under the framework set out in [Mayo Collaborative Servs. v. Prometheus Labs., Inc., 132 S. Ct. 1282 (2012)], or that such a challenge would have been futile prior to Alice."
