Portfolio overview
Vision RT Limited has been granted 42 US utility patents between 2015 and 2025, placing Vision RT Limited at #7,798 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.8 claims per patent with primary concentration in A61N (ELECTROTHERAPY; MAGNETOTHERAPY; RADIATION THERAPY; ULTRASOUND THERAPY). As a Foreign Corporation, Vision RT Limited is one of the more focused assignees in the PatentsView dataset. By volume, Vision sits between University Of Strathclyde (42 patents, rank #7,792) and Wind River Systems, Inc. (42 patents, rank #7,800) - the closest US assignees by grant volume. The composite Innovation Score of 40.2/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 23 grants, compared with 14 in the 2015–2019 window, a +64% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.
Claim depth and technology breadth describe this aggregate record. Vision RT Limited's 13.8 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 9 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

- Most of this portfolio concentrates in A61N - see who else leads that technology area. A61N leaders
- Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works
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.
