Across all tracked assignees
USPTO PatentsView assignee record - 10 granted patents across 4 technology areas, active 2024–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: C08K (Use of inorganic or non-macromolecular organic substances as compounding ingredients).
The verdict
Staedtler holds 10 US patents across 4 technology areas, rank #27,388 of 50,000 tracked assignees.
Staedtler SE has been granted 10 US utility patents between 2024 and 2025, placing Staedtler SE at rank #27,388 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 2.3 claims per patent with primary concentration in C08K (Use of inorganic or non-macromolecular organic substances as compounding ingredients). As a Foreign Corporation, Staedtler SE is one of the more focused assignees in the PatentsView dataset. By volume, Staedtler sits between SPP Technologies, Co., Ltd. (10 patents, rank #27,384) and Statoil ASA (10 patents, rank #27,392) - the closest US assignees by grant volume. The composite Innovation Score of 23.4/100 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. Historical data spans 2024 through 2025, with 10 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Staedtler SE's 2.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Staedtler SE against peers pursuing similar technology classes.

How to use this portfolio
Staedtler's 10 grants land it in the top 88% 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.
