The verdict
Eyebright holds 8 US patents across 10 technology areas, rank #31,538 of 50,000 tracked assignees.
Eyebright Medical Technology (beijing) Co., Ltd. has been granted 8 US utility patents between 2018 and 2025, placing Eyebright Medical Technology (beijing) Co., Ltd. at rank #31,538 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.5 claims per patent with primary concentration in A61F (FILTERS IMPLANTABLE INTO BLOOD VESSELS; PROSTHESES; DEVICES PROVIDING PATENCY TO, OR PREVENTING COLLAPSING OF, TUBULAR STRUCTURES OF THE BODY, e.g. STENTS; ORTHOPAEDIC, NURSING OR CONTRACEPTIVE DEVICE). As a Foreign Corporation, Eyebright Medical Technology (beijing) Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Eyebright sits between Evonetix Ltd (8 patents, rank #31,534) and Eastman Outdoors, Llc (8 patents, rank #31,542) - the closest US assignees by grant volume. The composite Innovation Score of 48.7/100 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 7 grants, compared with 1 in the 2015–2019 window, a +600% 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. Eyebright Medical Technology (beijing) Co., Ltd.'s 16.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Eyebright Medical Technology (beijing) Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Eyebright's 8 grants land it in the top 16% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
