Company patents

STMICROELECTRONICS (ROUSSET) SAS

STMICROELECTRONICS (ROUSSET) SAS's patent strategy shows a broad decline across its core semiconductor categories, with significant year-over-year drops in key areas like Transistor & Device Structure (-81.8% in 2025) and Memory & Storage (Static) (-42.1% in 2025), indicating a potential shift away from foundational semiconductor component innovation. The consistent decline in all listed categories, including a -90.9% drop in Computer Security patents so far in 2026, suggests a company-wide re-evaluation of its patenting priorities, with no emerging areas of rapid growth evident in its current portfolio.
