The verdict
Bolton holds 99 US patents across 9 technology areas, rank #3,673 of 50,000 tracked assignees.
Bolton Medical, Inc. has been granted 99 US utility patents between 2015 and 2025, placing Bolton Medical, Inc. at rank #3,673 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.5 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 US Corporation, Bolton Medical, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Bolton sits between Technische Universitaet Dresden (100 patents, rank #3,669) and Corteva Agriscience Llc (99 patents, rank #3,677) - the closest US assignees by grant volume. The composite Innovation Score of 55.0/100 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 70 grants, compared with 29 in the 2015–2019 window, a +141% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The US 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. Bolton Medical, Inc.'s 15.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Bolton Medical, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Bolton's 99 grants land it in the top 7% 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.
