Portfolio overview

Sakai Chemical Industry Co., Ltd. has been granted 64 US utility patents between 2015 and 2025, placing Sakai Chemical Industry Co., Ltd. at rank #5,400 across all assignees tracked by PlainPatent. This portfolio spans 47 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.8 claims per patent with primary concentration in C01P (INDEXING SCHEME RELATING TO STRUCTURAL AND PHYSICAL ASPECTS OF SOLID INORGANIC COMPOUNDS). As a Foreign Corporation, Sakai Chemical Industry Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 48.0/100 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 27 grants, compared with 37 in the 2015–2019 window — a -27% 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. Sakai Chemical Industry Co., Ltd.'s 9.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 47 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sakai Chemical Industry Co., Ltd. against peers pursuing similar technology classes.
