Portfolio overview

Yokogawa Electric Corporation has been granted 788 US utility patents between 2015 and 2025, placing Yokogawa Electric Corporation at rank #572 across all assignees tracked by PlainPatent. This portfolio spans 126 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.4 claims per patent with primary concentration in G05B (CONTROL OR REGULATING SYSTEMS IN GENERAL; FUNCTIONAL ELEMENTS OF SUCH SYSTEMS; MONITORING OR TESTING ARRANGEMENTS FOR SUCH SYSTEMS OR ELEMENTS). As a Foreign Corporation, Yokogawa Electric Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Yokogawa sits between Bally Gaming, Inc. (792 patents, rank #568) and Osram OLED Gmbh (781 patents, rank #576) - the closest US assignees by grant volume. The composite Innovation Score of 62.3/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 448 grants, compared with 340 in the 2015–2019 window, a +32% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Yokogawa Electric Corporation's 12.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Yokogawa Electric Corporation against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
