Portfolio overview
Massachusetts Eye and Ear Infirmary has been granted 166 US utility patents between 2015 and 2025, placing Massachusetts Eye and Ear Infirmary at rank #2,361 across all assignees tracked by PlainPatent. This portfolio spans 47 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.0 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a US Corporation, Massachusetts Eye and Ear Infirmary is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 56.5/100 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 103 grants, compared with 63 in the 2015–2019 window — a +63% 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. Massachusetts Eye and Ear Infirmary's 16.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 47 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Massachusetts Eye and Ear Infirmary against peers pursuing similar technology classes.
