Jason Sheasby – Building Big Ideas Into Courtroom Results

Jason Sheasby has built a career around taking complex ideas and making them work in the real world. In his case, that world is the courtroom. Over more than two decades, he has become one of the most respected trial lawyers in intellectual property law. His path shows how curiosity, discipline, and long-term thinking can shape a career with real impact.

Early life and curiosity

Sheasby grew up in San Bernardino County, California. He has said that his early years taught him that people see problems differently. “I learned early on that perspective matters,” he has shared. “Where you stand often shapes how you think.”

That interest in how people think led him to study philosophy at Pomona College. He earned his BA there and graduated summa cum laude, with Phi Beta Kappa honors. Philosophy may seem far from patent trials, but Sheasby sees a direct link. “Philosophy trains you to break down ideas,” he has said. “Law is about doing that under pressure.”

Education that shaped a trial lawyer

After Pomona, Sheasby went to Harvard Law School. He earned his JD cum laude in 1999. At Harvard, he sharpened the skills that would later define his career. He learned how to argue clearly, write precisely, and think several steps ahead.

Looking back, he often points to law school as a place where theory met practice. “You learn that big ideas only matter if you can apply them,” he has said. That belief would guide his work as a trial attorney.

Building a career at the trial table

Sheasby is now a partner at Irell & Manella LLP, a firm known for high-stakes litigation. His role is clear. He is a trial lawyer. He focuses on cases involving deep technology, significant business risk, and intense scrutiny.

In a short span of time, his trial record has stood out. In less than two years, he took more than 10 complex cases to trial and won each. These were not simple disputes. They involved patents, contracts, and billions of dollars in potential exposure.

One of the most notable matters involved memory technology company Netlist and Samsung. In multiple trials between 2023 and 2025, juries found infringement, willful conduct, and major damages. In March 2025, as co-lead counsel, Sheasby secured a key victory confirming that Netlist had properly terminated a license Samsung relied on as a defense.

“What matters most is clarity,” Sheasby has said about trial work. “You have to help a jury understand why the facts and the law fit together.”

Turning complex technology into clear stories

Sheasby’s work often sits at the intersection of law and technology. He has handled cases involving computer memory, data storage, USB chargers, and medical devices. In each case, the challenge is the same. Translate complex systems into simple stories.

In 2024, he co-led a trial against Anker Innovations for Fundamental Innovation Systems. The jury found willful infringement and awarded damages higher than requested. That same year, he helped secure major verdicts for G+ Communications and StreamScale.

Sheasby credits preparation and teamwork. “Trials are never about one person,” he has said. “They are about teams that respect the details.”

Recognition without distraction

The legal industry has taken notice. Sheasby has been named Litigator of the Year by The American Lawyer. He has been recognized by Chambers USA, Law360, Managing IP, and the Daily Journal. He has also been selected for lists like the Lawdragon 500 Leading Global IP Lawyers.

Still, he avoids focusing on awards. “Recognition is nice,” he has said. “But it’s not why you show up every day.”

Beyond the courtroom

Outside of litigation, Jason Sheasby brings his ideas to life in other ways. He is a founder of TORL Biotherapeutics, reflecting his interest in science and innovation. He also serves on the board of Pomona College, giving back to the institution that shaped his early thinking.

Service matters to him. “Institutions last when people invest in them,” he has said. His board work reflects a long-term view of impact beyond any single case.

A career built on big ideas and discipline

From philosophy student to leading trial lawyer, Jason Sheasby’s career follows a clear line. He takes big, complex ideas and works patiently to make them understandable and effective. Whether in a courtroom, a boardroom, or a startup, his approach stays the same.

“You don’t need to be flashy,” he has said. “You need to be prepared and honest about the work.”

That mindset has helped him shape outcomes, influence an industry, and build a career defined by substance over spectacle.
