Portfolio overview

Kansai COKE AND Chemicals Co., Ltd. has been granted 8 US utility patents between 2015 and 2025, placing Kansai COKE AND Chemicals Co., Ltd. at rank #32,203 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.9 claims per patent with primary concentration in C01P (INDEXING SCHEME RELATING TO STRUCTURAL AND PHYSICAL ASPECTS OF SOLID INORGANIC COMPOUNDS). As a Foreign Corporation, Kansai COKE AND Chemicals Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Kansai sits between KAIA Health Software Gmbh (8 patents, rank #32,199) and Kautex Maschinenbau Gmbh (8 patents, rank #32,207) - the closest US assignees by grant volume. The composite Innovation Score of 38.7/100 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 3 grants, compared with 5 in the 2015–2019 window, a -40% 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. Kansai COKE AND Chemicals Co., Ltd.'s 6.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kansai COKE AND Chemicals Co., 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.
