A.L.M. Holding Company v. Zydex Industries Private Ltd.

A.L.M. Holding Company v. Zydex Industries Private Ltd. A patent owner that retains a right to sue, a sublicensing veto (with pass-through royalties), and royalty interests retains a non-illusory exclusionary right sufficient for Article III constitutional standing, even after granting an exclusive license to commercialize the patents. The district court applied too demanding a threshold by treating the retained right to sue as insufficient standing alone, without accounting for the combined effect of the sublicensing veto and royalty interests that prevented the licensee from unilaterally extinguishing the owner's enforcement right. Patent owners who retain a right to sue paired with sublicensing veto rights and royalty interests have Article III standing even under a broad exclusive license—and statutory standing cases like Mann remain instructive on the constitutional standing inquiry, contrary to the approach some district courts had taken of treating the two analyses as entirely separate. Reversed and remanded; costs to appellant. Patent owner A.L.M./Ergon licensed exclusive commercialization rights to Ingevity but retained: (1) the right to sue third-party infringers (with shared or sole control depending on whether Ingevity elects to join), (2) a veto over Ingevity's sublicenses (not to be unreasonably withheld, but requiring consent and pass-through royalties), and (3) royalty interests including from sublicensees. The Federal Circuit held these retained rights collectively constitute a non-illusory exclusionary right for Article III purposes because Ingevity cannot unilaterally grant a royalty-free sublicense to an accused infringer and thereby moot the patent owner's suit—the key distinction from Morrow, where the plaintiff held only a bare contractual right to sue stripped of all other patent rights. The court clarified that statutory standing cases (particularly Mann) are instructive—though not controlling—on the constitutional standing inquiry: the factual question of whether a licensee's powers render the patent owner's enforcement right illusory arises under both analyses, and Zebra Technologies had already cited Mann approvingly in a constitutional standing context. The court rejected the district court's bright-line separation of constitutional and statutory standing precedents, holding that the same facts bearing on 'all substantial rights' can also bear on whether the owner retained a concrete exclusionary interest, though the two legal standards remain distinct. Morrow distinguished: Morrow involved a non-owner licensee holding only a bare right to sue, where the patent owner could moot any suit by granting a royalty-free sublicense; here, the plaintiff is the patent owner and Ingevity's sublicensing right is constrained by consent and royalty obligations that preserve the owner's enforcement interest. standing / jurisdiction infringement remand precedential standing / jurisdiction infringement remand precedential standing / jurisdiction remand precedential
