USPTO PatentsView assignee record - 10 granted patents across 5 technology areas, active 2015–2017. 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
Stein holds 10 US patents across 5 technology areas, rank #27,393 of 50,000 tracked assignees.
Stein & Co. Gmbh has been granted 10 US utility patents between 2015 and 2017, placing Stein & Co. Gmbh at rank #27,393 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.8 claims per patent with primary concentration in A47L (DOMESTIC WASHING OR CLEANING ; SUCTION CLEANERS IN GENERAL). As a Foreign Corporation, Stein & Co. Gmbh is one of the more focused assignees in the PatentsView dataset. By volume, Stein sits between Stafast Products, Inc. (10 patents, rank #27,389) and Streamline Innovations, Inc. (10 patents, rank #27,397) - the closest US assignees by grant volume. The composite Innovation Score of 22.7/100 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 0 grants, compared with 10 in the 2015–2019 window, a -100% 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. Stein & Co. Gmbh's 10.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Stein & Co. Gmbh against peers pursuing similar technology classes.

How to use this portfolio
Stein's 10 grants land it in the top 89% 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.
