How Judge Donato decides

Patterns drawn from this judge's own signed orders. Every observation links to the order it came from.

What persuades

In antitrust cases he denies a motion to dismiss where the complaint's monopolization theory raises factual disputes that cannot be resolved on the pleadings.

“The parties' familiarity with the record is assumed, and the motion is denied. ... Facebook's contentions to the contrary raise factual disputes that are not amenable to resolution in a motion to dismiss.”

In data-privacy class actions he grants a motion to dismiss only as to the legally deficient claim (such as a Stored Communications Act count) and lets the remaining claims proceed.

“Defendant Flo Health's motion to dismiss the consolidated complaint is granted for the Stored Communications Act claim and denied for all other claims.”

Procedural preferences

He applies Daubert rigorously and case-dispositively: excluding a plaintiff's essential expert opinion can leave no triable issue, and he then grants summary judgment for the defendant.

“Dr. Economides' opinions are excluded, and summary judgment is granted in favor of Meta.”

He excludes expert opinions when a necessary analytical link depends on an assumption that is not supported by record evidence.

“The expert's opinion must rest on actual data, not unfounded assumptions.”

Cautions

He treats a post-trial motion to decertify the class as an improper attempt to reconsider the certification order and denies it; he does not readily disturb a jury verdict on renewed JMOL or new-trial motions.

“Meta's request is nothing more than an improper attempt to seek reconsideration of the certification order. ... This is enough to deny the request without further discussion. ... Meta's post-trial motions for decertification, judgment as a matter of law, or for a new trial are denied. Dkt. Nos. 765, 766.”

In a patent case, Donato issued a second claim-construction order to resolve a dispute that surfaced during a Rule 702 challenge. Reading the claim language, Federal Circuit precedent, and dictionary definitions together, he construed the word "set" to mean "two or more."

Caseload & timing

From public federal docket records for this judge.

Donato's San Francisco docket includes criminal matters, prisoner and civil-rights cases, consumer and contract disputes, and major multidistrict and class litigation. In Cleaves v. Sopha, he dismissed a lengthy pro se complaint after screening and adopting the conclusion that it still did not state a claim. That disposition arose from statutory screening rather than a motion filed by a party.
