Portfolio overview

Sinox Company Ltd. has been granted 36 US utility patents between 2015 and 2025, placing Sinox Company Ltd. at rank #8,916 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.0 claims per patent with primary concentration in E05B (LOCKS; ACCESSORIES THEREFOR; HANDCUFFS). As a Foreign Corporation, Sinox Company Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Sinox sits between Sanuwave, Inc. (36 patents, rank #8,912) and Swiss Krono Tec Ag (36 patents, rank #8,920) - the closest US assignees by grant volume. The composite Innovation Score of 52.2/100 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 26 grants, compared with 10 in the 2015–2019 window, a +160% 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. Sinox Company Ltd.'s 10.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sinox Company Ltd. 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.
