Portfolio overview

Kabushiki Kaisha Kinki has been granted 6 US utility patents between 2016 and 2020, placing Kabushiki Kaisha Kinki at rank #41,138 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.5 claims per patent with primary concentration in B02C (CRUSHING, PULVERISING, OR DISINTEGRATING IN GENERAL; MILLING GRAIN). As a Foreign Corporation, Kabushiki Kaisha Kinki is one of the more focused assignees in the PatentsView dataset. By volume, Kabushiki sits between K.u. Leuven Research & Development (6 patents, rank #41,134) and KAHA PTE. Ltd. (6 patents, rank #41,142) - the closest US assignees by grant volume. The composite Innovation Score of 23.0/100 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 1 grants, compared with 5 in the 2015–2019 window, a -80% 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. Kabushiki Kaisha Kinki's 8.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kabushiki Kaisha Kinki against peers pursuing similar technology classes.
