Portfolio overview

Ushio Denki Kabushiki Kaisha has been granted 267 US utility patents between 2015 and 2025, placing Ushio Denki Kabushiki Kaisha at rank #1,556 across all assignees tracked by PlainPatent. This portfolio spans 96 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.1 claims per patent with primary concentration in H01J (ELECTRIC DISCHARGE TUBES OR DISCHARGE LAMPS). As a Foreign Corporation, Ushio Denki Kabushiki Kaisha is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Ushio sits between Fujikin Incorporated (267 patents, rank #1,552) and Sumitomo Electric Device Innovations, Inc. (266 patents, rank #1,560) - the closest US assignees by grant volume. The composite Innovation Score of 58.4/100 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 135 grants, compared with 132 in the 2015–2019 window, a +2% 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. Ushio Denki Kabushiki Kaisha's 11.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 96 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ushio Denki Kabushiki Kaisha against peers pursuing similar technology classes.
