Portfolio overview

Edwards Limited has been granted 173 US utility patents between 2015 and 2025, placing Edwards Limited at rank #2,266 across all assignees tracked by PlainPatent. This portfolio spans 75 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.5 claims per patent with primary concentration in F04C (ROTARY-PISTON, OR OSCILLATING-PISTON, POSITIVE-DISPLACEMENT MACHINES FOR LIQUIDS ; ROTARY-PISTON, OR OSCILLATING-PISTON, POSITIVE-DISPLACEMENT PUMPS). As a Foreign Corporation, Edwards Limited is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Edwards sits between Beckhoff Automation Gmbh (173 patents, rank #2,262) and The Government Of The United States Of America, As Represented By The Secretary Of Homeland Security (173 patents, rank #2,270) - the closest US assignees by grant volume. The composite Innovation Score of 60.1/100 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 99 grants, compared with 74 in the 2015–2019 window, a +34% 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. Edwards Limited's 14.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 75 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Edwards Limited against peers pursuing similar technology classes.

How to use this portfolio

Edwards's 173 grants land it in the top 4% 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 - Edwards ranks #2,266 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in F04C - see who else leads that technology area. F04C 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.
