Experience

Marcus Thorne is a specialist in Semiconductor and hardware engineering law. His practice covers the entire lifecycle of silicon innovation, from initial chip architecture patents to complex Section 337 investigations before the International Trade Commission (ITC). Marcus is a "technical" lawyer who spent five years as a patent examiner before entering private practice.

Representative Matters:

  • Foundry Trade Secret Theft: Represented a major semiconductor manufacturer in a trade secret misappropriation case involving 7nm node fabrication processes. After a three-week trial, secured a permanent injunction against a competitor’s use of the stolen blueprints.

  • Mobile Processor Litigation: In a multi-patent suit involving power management in ARM-based chips, Marcus served as lead trial counsel. He successfully invalidated three out of four asserted patents via Inter Partes Review (IPR) proceedings, forcing a settlement on highly favorable terms for his client.

  • ITC Investigation: Defended a consumer electronics giant in an ITC "Fast Track" investigation involving Wi-Fi 6 chipset patents. Marcus successfully argued for a "No Violation" finding, preventing an exclusion order that would have halted the client’s North American imports.
