USPTO PatentsView assignee record - 50 granted patents across 29 technology areas, active 2018–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: A47L (DOMESTIC WASHING OR CLEANING ; SUCTION CLEANERS IN GENERAL).
The verdict
Alfred holds 50 US patents across 29 technology areas, rank #6,614 of 50,000 tracked assignees.
Alfred Kärcher SE & Co. KG has been granted 50 US utility patents between 2018 and 2025, placing Alfred Kärcher SE & Co. KG at rank #6,614 across all assignees tracked by PlainPatent. This portfolio spans 29 distinct Cooperative Patent Classification (CPC) subclasses, averaging 27.6 claims per patent with primary concentration in A47L (DOMESTIC WASHING OR CLEANING ; SUCTION CLEANERS IN GENERAL). As a Foreign Corporation, Alfred Kärcher SE & Co. KG is one of the more focused assignees in the PatentsView dataset. By volume, Alfred sits between Yoshino Gypsum Co., Ltd. (51 patents, rank #6,610) and Axell Corporation (50 patents, rank #6,618) - the closest US assignees by grant volume. The composite Innovation Score of 50.5/100 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 32 grants, compared with 18 in the 2015–2019 window, a +78% 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. Alfred Kärcher SE & Co. KG's 27.6 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 29 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Alfred Kärcher SE & Co. KG against peers pursuing similar technology classes.

How to use this portfolio
Alfred's 50 grants land it in the top 13% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
