Portfolio overview

Edwards Japan Limited has been granted 120 US utility patents between 2015 and 2025, placing Edwards Japan Limited at rank #3,130 across all assignees tracked by PlainPatent. This portfolio spans 36 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.3 claims per patent with primary concentration in F04D (NON-POSITIVE-DISPLACEMENT PUMPS). As a Foreign Corporation, Edwards Japan Limited is one of the more focused assignees in the PatentsView dataset. By volume, Edwards sits between Shukla Medical (121 patents, rank #3,126) and Ixia (120 patents, rank #3,134) - the closest US assignees by grant volume. The composite Innovation Score of 53.6/100 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 89 grants, compared with 31 in the 2015–2019 window, a +187% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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 Japan Limited's 9.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 36 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Edwards Japan Limited against peers pursuing similar technology classes.

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.
