Portfolio overview

HARMONIC DRIVE SYSTEMS INC. has been granted 150 US utility patents between 2015 and 2025, placing HARMONIC DRIVE SYSTEMS INC. at rank #2,591 across all assignees tracked by PlainPatent. This portfolio spans 29 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.5 claims per patent with primary concentration in F16H (GEARING). As a Foreign Corporation, HARMONIC DRIVE SYSTEMS INC. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 43.6/100 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 78 grants, compared with 72 in the 2015–2019 window — a +8% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. HARMONIC DRIVE SYSTEMS INC.'s 6.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 29 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark HARMONIC DRIVE SYSTEMS INC. against peers pursuing similar technology classes.
