Portfolio overview
Massachusetts General Hospital has been granted 11 US utility patents between 2015 and 2024, placing Massachusetts General Hospital at rank #24,733 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.1 claims per patent with primary concentration in G01R (MEASURING ELECTRIC VARIABLES; MEASURING MAGNETIC VARIABLES). As a US Corporation, Massachusetts General Hospital is one of the more focused assignees in the PatentsView dataset. By volume, Massachusetts sits between Manta Sleep Llc (11 patents, rank #24,729) and Mbrico, Llc (11 patents, rank #24,737) - the closest US assignees by grant volume. The composite Innovation Score of 28.4/100 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 2 grants, compared with 9 in the 2015–2019 window, a -78% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Massachusetts General Hospital's 14.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Massachusetts General Hospital against peers pursuing similar technology classes.

How to use this portfolio
Massachusetts's 11 grants land it in the top 73% by Innovation Score, but volume alone doesn't tell you where the strength sits.
- Read that count against the largest US assignees before treating it as dominance - Massachusetts ranks #24,733 of 50,000. Top 50 holders
- Most of this portfolio concentrates in G01R - see who else leads that technology area. G01R 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.
