Portfolio overview

Kärcher North America, Inc. has been granted 31 US utility patents between 2015 and 2021, placing Kärcher North America, Inc. at #10,084 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.3 claims per patent with primary concentration in A47L (DOMESTIC WASHING OR CLEANING ; SUCTION CLEANERS IN GENERAL). As a US Corporation, Kärcher North America, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Kärcher sits between Kent Displays, Inc. (31 patents, rank #10,080) and Larson Manufacturing Company Of South Dakota, Llc (31 patents, rank #10,088) - the closest US assignees by grant volume. The composite Innovation Score of 31.4/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 3 grants, compared with 28 in the 2015–2019 window, a -89% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The US Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Kärcher North America, Inc.'s 10.3 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 14 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
