Portfolio overview

Nippon ITF, Inc. has been granted 9 US utility patents between 2018 and 2023, placing Nippon ITF, Inc. at rank #29,543 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.2 claims per patent with primary concentration in C23C (COATING METALLIC MATERIAL; COATING MATERIAL WITH METALLIC MATERIAL; SURFACE TREATMENT OF METALLIC MATERIAL BY DIFFUSION INTO THE SURFACE, BY CHEMICAL CONVERSION OR SUBSTITUTION; COATING BY VACUUM EVAP). As a Foreign Corporation, Nippon ITF, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Nippon sits between Ningbo Sunfree Motor Technology Company Limited (9 patents, rank #29,539) and Nitero PTY Ltd (9 patents, rank #29,547) - the closest US assignees by grant volume. The composite Innovation Score of 34.3/100 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 5 grants, compared with 4 in the 2015–2019 window, a +25% 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. Nippon ITF, Inc.'s 13.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nippon ITF, Inc. 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.
