Portfolio overview

Neturen Co., Ltd. has been granted 86 US utility patents between 2015 and 2025, placing Neturen Co., Ltd. at rank #4,165 across all assignees tracked by PlainPatent. This portfolio spans 38 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.3 claims per patent with primary concentration in H05B (ELECTRIC HEATING; ELECTRIC LIGHT SOURCES NOT OTHERWISE PROVIDED FOR; CIRCUIT ARRANGEMENTS FOR ELECTRIC LIGHT SOURCES, IN GENERAL). As a Foreign Corporation, Neturen Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Neturen sits between Kent State University (86 patents, rank #4,161) and ROBE Lighting S.r.o. (86 patents, rank #4,169) - the closest US assignees by grant volume. The composite Innovation Score of 45.9/100 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 46 grants, compared with 40 in the 2015–2019 window, a +15% 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. Neturen Co., Ltd.'s 7.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 38 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Neturen 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.
