Portfolio overview

YOKOWO CO., LTD. has been granted 114 US utility patents between 2015 and 2025, placing YOKOWO CO., LTD. at rank #3,296 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.6 claims per patent with primary concentration in H01Q (ANTENNAS, i.e. RADIO AERIALS). As a Foreign Corporation, YOKOWO CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 48.3/100 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 87 grants, compared with 27 in the 2015–2019 window — a +222% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. YOKOWO CO., LTD.'s 13.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, 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 YOKOWO CO., LTD. against peers pursuing similar technology classes.
