Portfolio overview

Kabushiki Kaisha Isowa has been granted 30 US utility patents between 2015 and 2025, placing Kabushiki Kaisha Isowa at rank #10,372 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.9 claims per patent with primary concentration in B31B (MAKING CONTAINERS OF PAPER, CARDBOARD OR MATERIAL WORKED IN A MANNER ANALOGOUS TO PAPER). As a Foreign Corporation, Kabushiki Kaisha Isowa is one of the more focused assignees in the PatentsView dataset. By volume, Kabushiki sits between Knipex-werk C. Gustav Putsch KG (30 patents, rank #10,368) and Kolcraft Enterprises, Inc. (30 patents, rank #10,376) - the closest US assignees by grant volume. The composite Innovation Score of 35.7/100 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 13 grants, compared with 17 in the 2015–2019 window, a -24% 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 Isowa's 9.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 16 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kabushiki Kaisha Isowa 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.
