Judge Evette D. Pennypacker

Judge Evette D. Pennypacker brings a distinctive intellectual property and technology law background to the Santa Clara County Superior Court bench, having been appointed by Governor Jerry Brown in June 2018 specifically because of her reputation as one of Silicon Valley's foremost IP experts. This pre-bench specialization is highly significant: she is not a generalist who learned technology law on the bench, but rather a practitioner who spent her career immersed in the precise legal and technical disputes that define Silicon Valley litigation. Attorneys should expect a judge who can parse technical arguments with sophistication and who will not be easily impressed by superficial or oversimplified explanations of complex technology or IP concepts. The two most notable public cases associated with Judge Pennypacker reveal a judge willing to impose substantial consequences for non-compliance and to engage with cutting-edge evidentiary and factual disputes. Her $1.2 million sanction against Calvary Chapel San Jose for defying COVID-19 public health restrictions — a ruling upheld on appeal as of April 2025 — signals a judge who takes court orders and regulatory compliance seriously and is not reluctant to impose significant monetary penalties when parties defy legal mandates. Her handling of Tesla litigation involving Elon Musk's Autopilot statements and a novel deepfake defense argument further illustrates her comfort with technologically complex, high-profile, and legally novel disputes. With no analyzed rulings or attorney observations in the current dataset, the confidence level for this profile is necessarily limited, and practitioners should treat these inferences as directional rather than definitive. The profile warrants ongoing monitoring as additional rulings and practitioner feedback become available.

Given Judge Pennypacker's deep IP and technology background, attorneys appearing before her — particularly in technology, patent, trade secret, or complex commercial matters — should resist the temptation to over-simplify technical arguments. She will likely appreciate precise, technically accurate briefing and may be skeptical of attorneys who gloss over technical details or rely on analogies that obscure rather than illuminate. Conversely, attorneys in non-IP matters should not assume she lacks rigor; her background suggests a disciplined, analytically demanding approach across subject matter areas. The Calvary Chapel sanction ruling is a critical data point for compliance and procedural strategy. Judge Pennypacker has demonstrated willingness to impose large monetary sanctions when parties defy court orders or regulatory mandates, and that ruling survived appellate review, suggesting her legal reasoning was well-grounded. Attorneys should ensure their clients are in strict compliance with any outstanding orders before appearing, and should not counsel clients to test the boundaries of court directives. Any argument that a party was substantially compliant or had good-faith reasons for non-compliance should be supported by detailed factual records. For novel or emerging legal issues — such as the deepfake defense argument raised in the Tesla litigation — Judge Pennypacker appears willing to engage with cutting-edge arguments rather than reflexively dismissing them. Attorneys with innovative legal theories should brief them thoroughly and anchor them in existing doctrine, as a judge with her background will probe both the novelty and the legal foundation of any argument.

  Audit Client Compliance with All Outstanding Orders

  Before any appearance, confirm that your client is in full compliance with all court orders, discovery obligations, and any applicable regulatory mandates. Given the $1.2 million Calvary Chapel sanction, Judge Pennypacker has demonstrated she will impose and defend substantial penalties for non-compliance. Any compliance gaps should be remediated and disclosed proactively.

  Prepare Technically Precise Briefing

  In any matter involving technology, IP, software, AI, or complex commercial products, ensure that technical facts are stated accurately and that legal arguments are grounded in precise technical understanding. Judge Pennypacker's IP background means she will scrutinize technical claims closely. Retain qualified experts early and ensure expert declarations are technically rigorous.

  Research Local Rules and Courtroom Practices

  With no attorney observation data available, directly research Judge Pennypacker's specific courtroom preferences, tentative ruling practices, oral argument procedures, and any standing orders. Contact the clerk's office and consult practitioners who have appeared before her recently to fill this intelligence gap.

  Anchor Novel Arguments in Existing Doctrine

  If raising cutting-edge or novel legal theories, prepare comprehensive briefing that traces the argument from established precedent to the novel application. Do not rely on the novelty itself as persuasive — demonstrate why existing legal principles compel or support the new argument.

• important

  Prepare for Substantive Oral Argument

  Given her sophisticated background, Judge Pennypacker is likely to engage substantively during oral argument rather than simply accepting prepared remarks. Attorneys should be prepared to answer detailed technical and legal questions and should not rely solely on written submissions.

  Monitor Appellate Decisions Involving Her Rulings

  Track any appellate decisions reviewing Judge Pennypacker's rulings, as these provide the clearest window into her legal reasoning and judicial philosophy. The Calvary Chapel appeal (upheld April 2025) is one confirmed data point; additional appellate outcomes will sharpen the profile significantly.

• ›Demonstrate technical precision: do not approximate or generalize technical facts, particularly in IP, software, or AI-related matters. Judge Pennypacker's background means she will notice inaccuracies that a generalist judge might miss.
• ›Comply strictly with all court orders and deadlines before appearing. Any history of non-compliance should be addressed proactively and with a detailed explanation — do not assume it will go unnoticed or be treated leniently.
• ›Be prepared for substantive judicial engagement on complex issues. Do not deliver a rote presentation; anticipate detailed questions on both technical facts and legal doctrine and have authoritative answers ready.

• ›Maintain professional decorum consistent with a high-profile, sophisticated court. Judge Pennypacker has presided over significant public interest and technology cases and will expect counsel to match the gravity of the proceedings.
