Portfolio overview

Ewald Dörken Ag has been granted 21 US utility patents between 2015 and 2025, placing Ewald Dörken Ag at #13,978 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 28 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.1 claims per patent with primary concentration in B32B (LAYERED PRODUCTS, i.e. PRODUCTS BUILT-UP OF STRATA OF FLAT OR NON-FLAT, e.g. CELLULAR OR HONEYCOMB, FORM). As a Foreign Corporation, Ewald Dörken Ag is one of the more focused assignees in the PatentsView dataset. By volume, Ewald sits between Emergency Alert Solutions Group, Llc (21 patents, rank #13,960) and Elsevier Inc. (21 patents, rank #13,968) - the closest US assignees by grant volume. The composite Innovation Score of 51.7/100 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 12 grants, compared with 8 in the 2015–2019 window, a +50% 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 Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Ewald Dörken Ag's 17.1 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 28 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
