Portfolio overview

Kabushiki Kaisha Kawai Gakki Seisakusho has been granted 41 US utility patents between 2015 and 2025, placing Kabushiki Kaisha Kawai Gakki Seisakusho at rank #7,869 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.9 claims per patent with primary concentration in G10C (PIANOS, HARPSICHORDS, SPINETS OR SIMILAR STRINGED MUSICAL INSTRUMENTS WITH ONE OR MORE KEYBOARDS). As a Foreign Corporation, Kabushiki Kaisha Kawai Gakki Seisakusho is one of the more focused assignees in the PatentsView dataset. By volume, Kabushiki sits between Inventec Appliances (shanghai) Co., Ltd. (41 patents, rank #7,865) and KYE Systems Corp. (41 patents, rank #7,873) - the closest US assignees by grant volume. The composite Innovation Score of 37.1/100 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 20 grants, compared with 21 in the 2015–2019 window, a -5% 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 Kawai Gakki Seisakusho's 6.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 21 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kabushiki Kaisha Kawai Gakki Seisakusho 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.
