Portfolio overview

Whirlpool S.a. has been granted 91 US utility patents between 2015 and 2024, placing Whirlpool S.a. at rank #3,993 across all assignees tracked by PlainPatent. This portfolio spans 47 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.3 claims per patent with primary concentration in F04B (POSITIVE-DISPLACEMENT MACHINES FOR LIQUIDS; PUMPS). As a Foreign Corporation, Whirlpool S.a. is one of the more focused assignees in the PatentsView dataset. By volume, Whirlpool sits between Transdermal Biotechnology, Inc. (91 patents, rank #3,989) and BWXT Mpower, Inc. (90 patents, rank #3,997) - the closest US assignees by grant volume. The composite Innovation Score of 47.5/100 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 6 grants, compared with 85 in the 2015–2019 window, a -93% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Whirlpool S.a.'s 10.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, 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 Whirlpool S.a. against peers pursuing similar technology classes.

How to use this portfolio

Whirlpool's 91 grants land it in the top 18% 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 - Whirlpool ranks #3,993 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in F04B - see who else leads that technology area. F04B 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.
