Background
Keezio Group began this patent litigation by seeking declaratory relief after SlumberPod accused Keezio’s product of infringement. SlumberPod responded with patent-infringement counterclaims. Pretrial rulings eliminated Keezio’s affirmative claims, leaving only SlumberPod’s infringement claims for trial. That created a presentation problem: Keezio remained the named plaintiff and ordinarily would proceed first, while SlumberPod carried the burden on the claims the jury would actually decide.
The parties briefed whether their trial designations should be changed. The court granted SlumberPod’s request in an August 2026 text order, then issued this memorandum to explain the ruling. The question was not whether SlumberPod had proved infringement or whether Keezio’s invalidity position had merit. It was the narrower matter of party alignment and order of presentation at the upcoming jury trial.
The Court’s Holding
Magistrate Judge Peter H. Kang exercised the court’s discretion to realign the parties. SlumberPod will be the named plaintiff at trial and Keezio the named defendant. The court reasoned that the new alignment tracks the case that remains: SlumberPod is the natural plaintiff because it asserts the only live causes of action and bears the burden of proving patent infringement.
Jury comprehension was central to the ruling. Presenting the dispute as an infringement action with an invalidity defense is easier to follow than presenting it as an invalidity action with infringement counterclaims, particularly after the declaratory claims have disappeared. The court noted that patent-trial guidance and other decisions similarly favor having the patentee proceed first when that structure reflects the issues and burdens the jury must resolve.
The court rejected Keezio’s reliance on a prior Northern District decision that had declined realignment. In that earlier case, summary judgment had already established infringement of claims from two patents, making invalidity the heart of the remaining trial. No comparable infringement ruling had been made here. Keezio’s burden on invalidity also did not alter the primary purpose of this trial, because invalidity ordinarily operates as a defense and could become immaterial if the jury finds no infringement.
The order changes labels and presentation sequence, not substantive rights. It does not decide infringement, invalidity, or any defense. Its effect is to place the party pressing the remaining affirmative patent claims first before the jury.
Key Takeaways
- Federal courts have discretion to realign parties for trial when the original caption no longer reflects the claims that remain after pretrial rulings.
- In a declaratory-judgment patent action, the patentee may become the trial plaintiff when only its infringement counterclaims remain and it bears the principal burden of proof.
- Clear jury presentation can justify realignment; courts may prefer an infringement case with an invalidity defense over the procedural reverse.
- A decision declining realignment after infringement was established on summary judgment does not control when infringement remains wholly unresolved.
- Realignment determines trial labels and order of presentation. It does not establish liability or alter the parties’ substantive burdens.
Why It Matters
Patent litigants should revisit trial alignment after dispositive motions and claim narrowing. The party that filed first may not retain the practical advantages of opening presentation if its affirmative claims are gone and the counterclaimant is now the only party seeking relief. Requests for realignment should focus on the live claims, burdens, and the simplest narrative for jurors.
The order is also a reminder to distinguish procedural precedent by the actual posture at trial. A prior infringement ruling can make validity the center of a case; without such a ruling, infringement remains the natural starting point. Counsel preparing pretrial statements, jury instructions, and exhibit sequences should account for that difference early.
