Portfolio overview

Tokyo Parts Industrial Co., Ltd. has been granted 30 US utility patents between 2015 and 2023, placing Tokyo Parts Industrial Co., Ltd. at rank #10,488 across all assignees tracked by PlainPatent. This portfolio spans 28 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.5 claims per patent with primary concentration in H02K (DYNAMO-ELECTRIC MACHINES). As a Foreign Corporation, Tokyo Parts Industrial Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 38.0/100 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 11 grants, compared with 19 in the 2015–2019 window, a -42% 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. Tokyo Parts Industrial Co., Ltd.'s 9.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 28 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Tokyo Parts Industrial Co., Ltd. against peers pursuing similar technology classes.
