Portfolio overview

Ichikoh Industries, Ltd. has been granted 128 US utility patents between 2015 and 2025, placing Ichikoh Industries, Ltd. at rank #2,968 across all assignees tracked by PlainPatent. This portfolio spans 27 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.4 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, Ichikoh Industries, Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Ichikoh sits between GAS Technology Institute (128 patents, rank #2,964) and NCR Voyix Corporation (128 patents, rank #2,972) - the closest US assignees by grant volume. The composite Innovation Score of 50.6/100 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 77 grants, compared with 51 in the 2015–2019 window, a +51% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Ichikoh Industries, Ltd.'s 8.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 27 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ichikoh Industries, 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.
