This week on IPWatchdog Unleashed our conversation is with Judge John Holcomb of the United States Federal District Court for the Central District of California, which took place March 4, 2025, at IPWatchdog LIVE.

Judge Holcomb is one of us. He was a patent professional—a patent litigator—before he joined the federal judiciary. He was appointed by President Donald J. Trump during his first term. And he serves in the Central District of California, with his courthouse located in Santa Ana, California. Early in his career Judge Holcomb was an attorney for Irell & Manella, which is a familiar name to many of us, and then also a partner for many years with Knobbe Martens.

We began our conversation with the story about how John Holcomb the patent litigator went from private practice to becoming Judge John Holcomb of the U.S. Federal District Court for the Central District of California. As we pivot from the nomination and confirmation process, I asked Judge Holcomb: Does it surprise you what you are seeing as a district court judge, or were you prepared for the wide array of different issues?

 And then we pivot to discussing patent litigation, the makeup of the Central District of California, advice for litigators, experts, the new Rule 702 and Daubert hearings and rulings on expert testimony, we discussed the role of the jury and how Judge Holcomb divides time for trial, as well as the number of patents and claims best suited for a single trial, we also discussed Judge Holcomb’s practice relating to summary judgment motions. As our conversation wound down, we ended on the topic of his judicial philosophy, and to make the point Judge Holcomb told the story of three umpires. Holcomb explains that he believes there is an objectively correct answer and that he is doing his very best to get it right.
