Portfolio overview

Nitto Boseki Co., Ltd. has been granted 54 US utility patents between 2015 and 2025, placing Nitto Boseki Co., Ltd. at rank #6,261 across all assignees tracked by PlainPatent. This portfolio spans 45 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.8 claims per patent with primary concentration in C03C (CHEMICAL COMPOSITION OF GLASSES, GLAZES OR VITREOUS ENAMELS; SURFACE TREATMENT OF GLASS; SURFACE TREATMENT OF FIBRES OR FILAMENTS MADE FROM GLASS, MINERALS OR SLAGS; JOINING GLASS TO GLASS OR OTHER MA). As a Foreign Corporation, Nitto Boseki Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Nitto sits between Mojo Mobility Inc. (54 patents, rank #6,257) and Progress Profiles SPA (54 patents, rank #6,265) - the closest US assignees by grant volume. The composite Innovation Score of 50.3/100 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 34 grants, compared with 20 in the 2015–2019 window, a +70% 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. Nitto Boseki Co., Ltd.'s 7.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 45 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nitto Boseki Co., Ltd. against peers pursuing similar technology classes.
