Lone Star v. Nanya: Judge Alsup denied dismissal, realigned AMD as a co-plaintiff, and allowed Lone Star to drop a patent claim.
Lone Star's patent-infringement case continued; AMD was realigned as an involuntary co-plaintiff, and the Nanya defendants' motion to dismiss was denied.
What happened
In Lone Star Silicon Innovations LLC v. Nanya Technology Corporation, Lone Star sued the Nanya defendants for patent infringement. The dispute concerned whether Lone Star had enough rights in the patents to bring the case and whether AMD needed to join it.
The defendants asked the court to dismiss the case, arguing that Lone Star lacked standing, AMD could not be forced to join as a plaintiff, and Lone Star improperly dropped a claim involving one patent. The court found that Lone Star had the kind of exclusive rights that allowed it to sue with the patent owner, as the appeals court had previously determined.
Judge William Alsup denied the motion to dismiss, realigned AMD as an involuntary co-plaintiff, and allowed the amendment dropping the challenged claim. The case therefore continued with Lone Star and AMD aligned as co-plaintiffs.

Background
Lone Star brought this patent-infringement action involving United States Patent Nos. 6,097,061 and 6,388,330. AMD had transferred patent rights to Lone Star under an agreement that gave Lone Star rights to sue for infringement, while retaining certain restrictions on Lone Star's enforcement and transfer of rights. An earlier order dismissed the action because Lone Star did not have all substantial rights in the patents.
The court of appeals agreed that Lone Star did not have all substantial rights, but held that Lone Star appeared to be an exclusive licensee with exclusionary rights. Such a licensee may sue with the patent owner. The appeals court therefore vacated the earlier dismissal and required that Lone Star be given an opportunity to join AMD as a necessary party.
On remand, Lone Star amended its complaint and named AMD as a defendant. AMD answered that it had declined to join voluntarily as a plaintiff. Lone Star alleged that AMD should be joined under Rule 19, which governs required parties. The amended complaint also dropped a claim under the '330 patent.
Arguments and analysis
The Nanya defendants again moved to dismiss under Rule 12(b)(6), arguing that Lone Star lacked standing, that AMD could not be involuntarily joined as a co-plaintiff, and that Lone Star exceeded the court's permission to amend by dropping the '330-patent claim.
The court held that the same patent-transfer agreement had already been determined by the court of appeals to give Lone Star enough rights to qualify as an exclusive licensee, provided AMD was made a party. Because AMD had been served and had answered, it was already a party, but it had been placed on the wrong side of the case.
The court explained that courts may look beyond how the complaint labels the parties and realign them according to their positions in the dispute. Because AMD was the patent owner, was within the case, and had declined to join voluntarily, the court held that AMD had to be lined up as an involuntary co-plaintiff alongside Lone Star.
The court also allowed Lone Star to drop the challenged '330-patent claim. Lone Star explained that the claim had been held unpatentable by the Patent Trial and Appeal Board. Although the amendment went slightly beyond the earlier order's stated permission to add AMD, the court allowed it.
Disposition
The court denied the motion to dismiss. It also realigned AMD as a co-plaintiff and allowed the amendment dropping the '330-patent claim. This order addressed standing, party alignment, and amendment issues; it did not decide whether the asserted patent was infringed.
