Portfolio overview

Ahlstrom OYJ has been granted 18 US utility patents between 2023 and 2025, placing Ahlstrom OYJ at #15,799 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 26 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.9 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, Ahlstrom OYJ is one of the more focused assignees in the PatentsView dataset. By volume, Ahlstrom sits between Admatechs Co., Ltd. (18 patents, rank #15,789) and Anexa LABS Llc (18 patents, rank #15,797) - the closest US assignees by grant volume. The composite Innovation Score of 59.6/100 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. Historical data spans 2023 through 2025, with 18 total grants over that period. 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. Ahlstrom OYJ's 18.9 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 26 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
