Portfolio overview

Mainstay Medical Limited has been granted 35 US utility patents between 2015 and 2025, placing Mainstay Medical Limited at rank #9,080 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 23.3 claims per patent with primary concentration in A61N (ELECTROTHERAPY; MAGNETOTHERAPY; RADIATION THERAPY; ULTRASOUND THERAPY). As a Foreign Corporation, Mainstay Medical Limited is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 41.7/100 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 20 grants, compared with 15 in the 2015–2019 window, a +33% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Mainstay Medical Limited's 23.3 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Mainstay Medical Limited against peers pursuing similar technology classes.
