Portfolio overview

Koito Manufacturing Co., Ltd. has been granted 902 US utility patents between 2015 and 2025, placing Koito Manufacturing Co., Ltd. at rank #496 across all assignees tracked by PlainPatent. This portfolio spans 118 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.1 claims per patent with primary concentration in F21S (NON-PORTABLE LIGHTING DEVICES; SYSTEMS THEREOF; VEHICLE LIGHTING DEVICES SPECIALLY ADAPTED FOR VEHICLE EXTERIORS). As a Foreign Corporation, Koito Manufacturing Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Koito sits between Mcafee, Llc (906 patents, rank #492) and Arkema France (892 patents, rank #500) - the closest US assignees by grant volume. The composite Innovation Score of 59.3/100 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 475 grants, compared with 427 in the 2015–2019 window, a +11% 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. Koito Manufacturing Co., Ltd.'s 9.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, 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 Koito Manufacturing Co., Ltd. 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.
