Judge Theodore C. Zayner

Judge Theodore C. Zayner sits on the Santa Clara County Superior Court, having been appointed by Governor Gavin Newsom in 2020. A Stanford Law School graduate with a background in private practice in Woodside, California, Judge Zayner brings a sophisticated civil litigation perspective to the bench. His pre-bench career as a private attorney — rather than a career prosecutor — suggests a judicial temperament shaped by adversarial civil practice, familiarity with complex commercial disputes, and an appreciation for the procedural and evidentiary nuances that private litigators navigate. This background distinguishes him from judges who came up through the DA's office and may translate into greater patience with complex civil motions and commercial litigation arguments. The notable cases associated with Judge Zayner reveal a docket that skews toward high-stakes, sophisticated commercial and technology disputes. His handling of the Tesla v. Rivian trade secrets case — ordering the matter to proceed to trial as of July 2024 — signals a willingness to let complex commercial disputes be resolved on the merits rather than disposed of on pretrial motions. His routing of Tencent/WeChat California privacy claims to arbitration in May 2025 demonstrates familiarity with arbitration clauses and a disposition to enforce contractual dispute resolution mechanisms. His administrative role in issuing COVID-19 public access protocols in January 2022 further suggests he has taken on leadership responsibilities within the court. With limited ruling data and no attorney observations in the current dataset, confidence in behavioral predictions remains moderate. However, the profile data — Stanford pedigree, Newsom appointment, Silicon Valley private practice background, and a docket featuring major tech-sector litigation — paints a picture of a judge comfortable with complex commercial matters, likely analytically rigorous, and attentive to procedural compliance. Attorneys appearing before Judge Zayner should expect a well-prepared bench with high expectations for counsel.

Given Judge Zayner's Stanford Law background and private civil practice career, attorneys should approach arguments with analytical precision and doctrinal rigor. Stanford-trained jurists tend to respond well to well-structured legal arguments that engage directly with the controlling authority, distinguish adverse precedent explicitly, and avoid rhetorical overreach. Avoid advocacy that relies heavily on emotional appeals or policy arguments untethered to legal doctrine — lead with the law, then support with equitable considerations. The Tesla v. Rivian trade secrets ruling and the Tencent arbitration decision together suggest that Judge Zayner takes contractual and statutory frameworks seriously. In trade secrets matters, expect the judge to scrutinize whether the alleged secrets are adequately identified and whether misappropriation is sufficiently pleaded or proven. In cases involving arbitration clauses, do not assume you can avoid arbitration on policy grounds — come prepared with specific legal arguments if you are opposing enforcement of an arbitration agreement, as the data suggests he is inclined to enforce such provisions. For motion practice, prepare thorough, well-organized briefs. A Stanford-trained judge with a civil litigation background will likely read the papers carefully and may arrive at hearings with pointed questions. Do not rely on oral argument to fill gaps in your briefing. Anticipate the weaknesses in your position and address them proactively in writing. If your case involves technology, intellectual property, or privacy law — areas prominent in his known docket — ensure your counsel or supporting experts can speak to technical nuances with precision.

• ›Arrive fully prepared on the law — a Stanford-trained judge with civil litigation experience will likely have read the briefs and may ask pointed, specific questions from the bench. Do not expect to educate the court on basic doctrine during argument.
• ›Be precise and concise in oral argument. Lead with your strongest legal authority and the dispositive issue. Avoid lengthy factual recitations unless specifically invited by the court.
• ›Treat opposing counsel professionally and avoid ad hominem attacks or hyperbolic characterizations of the other side's position — a civil litigator-turned-judge will likely view such tactics as unprofessional and counterproductive.
• ›Comply strictly with all procedural deadlines, page limits, and formatting requirements. His administrative leadership role suggests an organized judicial temperament that values procedural compliance.
• ›If you do not know the answer to a question from the bench, say so clearly and offer to submit supplemental briefing rather than speculating — intellectual honesty is likely valued by a Stanford-trained jurist.
