The verdict
Hefei holds 9 US patents across 12 technology areas, rank #28,927 of 50,000 tracked assignees.
Hefei CAS ION Medical AND Technical Devices Co., Ltd. has been granted 9 US utility patents between 2019 and 2023, placing Hefei CAS ION Medical AND Technical Devices Co., Ltd. at rank #28,927 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.2 claims per patent with primary concentration in H05H (PLASMA TECHNIQUE ; PRODUCTION OF ACCELERATED ELECTRICALLY-CHARGED PARTICLES OR OF NEUTRONS; PRODUCTION OR ACCELERATION OF NEUTRAL MOLECULAR OR ATOMIC BEAMS). As a Foreign Corporation, Hefei CAS ION Medical AND Technical Devices Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Hefei sits between HEAT AND Control, Inc. (9 patents, rank #28,923) and HERO Scientific Ltd. (9 patents, rank #28,931) - the closest US assignees by grant volume. The composite Innovation Score of 26.4/100 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 6 grants, compared with 3 in the 2015–2019 window, a +100% 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. Hefei CAS ION Medical AND Technical Devices Co., Ltd.'s 7.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hefei CAS ION Medical AND Technical Devices Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Hefei's 9 grants land it in the top 80% 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.
