Portfolio overview

Nitto Denko Corporation has been granted 1,608 US utility patents between 2015 and 2025, placing Nitto Denko Corporation at rank #266 across all assignees tracked by PlainPatent. This portfolio spans 207 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.1 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a Foreign Corporation, Nitto Denko Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Nitto sits between Stryker Corporation (1,619 patents, rank #262) and HERE Global B.v. (1,589 patents, rank #270) - the closest US assignees by grant volume. The composite Innovation Score of 62.4/100 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 686 grants, compared with 922 in the 2015–2019 window, a -26% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Nitto Denko Corporation's 11.1 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 Nitto Denko Corporation 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.
