How Judge Vyskocil decides
Patterns drawn from this judge's own signed orders. Every observation links to the order it came from.
What persuades
On summary judgment in fact-intensive areas (here a multi-factor trademark likelihood-of-confusion analysis), she will deny the motion where the non-movant raises genuine disputes across the governing factors rather than resolve confusion as a matter of law.
“Because Groq raises disputes of material fact as to virtually all of the factors set forth in”
Procedural preferences
On a Rule 12(b)(6) motion she holds parties to the four corners of the pleadings: she denied a motion to dismiss outright where the defendant's only argument relied on a document outside the complaint, declining to convert or consider extrinsic material. A movant before her should ground a dismissal argument in the pleading itself, not in attached evidence.
“Defendant’s sole argument for dismissal is based entirely on a document outside”
She enforces arbitration agreements and the delegation of arbitrability to the arbitrator, and where claims are arbitrable she stays the case pending arbitration rather than dismissing it.
“case is stayed pending arbitration”

Caseload & timing
From public federal docket records for this judge.
- A case-level sample of 21 dockets, dominated by very recent (2026) filings still pending, so this reflects her current intake, not a tenure-wide mix or grant context.
- A notable 2026 cluster is alien-detainee habeas corpus (28 U.S.C. 2241) and other immigration actions, which terminate fast: Arellano v. Warden (1:26-cv-03433, filed 2026-04-24, terminated 2026-05-06, ~12 days), Gomez-Gomez v. Mullin (1:26-cv-03427, filed 2026-04-26, terminated 2026-04-28, 2 days), Doe v. Borgen (1:26-cv-03718, filed 2026-05-05, terminated 2026-05-29, 24 days).
- These fast procedural terminations are not a basis for grounded dispositive-motion latency.
- Separately, a set of her 2019-2020 terminated civil dockets was reviewed to build the motion timeline below; those older commercial, securities, and defamation cases are where her contested dispositive rulings sit.
