Harry Winston SA

Harry Winston SA has been granted 876 US utility patents between 2015 and 2025, placing Harry Winston SA at rank #513 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.2 claims per patent with primary concentration in G04B (MECHANICALLY-DRIVEN CLOCKS OR WATCHES; MECHANICAL PARTS OF CLOCKS OR WATCHES IN GENERAL; TIME PIECES USING THE POSITION OF THE SUN, MOON OR STARS). As a Foreign Corporation, Harry Winston SA is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 52.0/100 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 609 grants, compared with 267 in the 2015–2019 window — a +128% 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. Harry Winston SA's 1.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Harry Winston SA against peers pursuing similar technology classes.
