How Judge Lee decides

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

What persuades

On the threshold question of the standard of proof in a patent-eligibility challenge, he held that the clear-and-convincing evidentiary standard governs only factual disputes and has no role in the purely legal Section 101 inquiry.

“the Court is persuaded that the clear-and-convincing standard has no role to play in the § 101 determination at issue in this case”

As a Rule 702 gatekeeper in a toxic-tort case, he required expert causation testimony tied to the plaintiff's own exposure level, treating a wholesale failure to quantify individual dosage as fatal to admissibility even where the general theory was theoretically possible.

“In contrast to the plaintiff in Schultz, Krik does not offer any expert testimony as to how much asbestos exposure he experienced and whether that dosage of exposure was sufficient to cause his lung cancer.”
