Portfolio overview

Hazen Paper Company has been granted 11 US utility patents between 2015 and 2025, placing Hazen Paper Company at rank #24,434 across all assignees tracked by PlainPatent. This portfolio spans 14 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 US Corporation, Hazen Paper Company is one of the more focused assignees in the PatentsView dataset. By volume, Hazen sits between Hangzhou Valgen Medtech Co., Ltd. (11 patents, rank #24,430) and Heidelbergcement Ag (11 patents, rank #24,438) - the closest US assignees by grant volume. The composite Innovation Score of 38.7/100 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 5 grants, compared with 6 in the 2015–2019 window, a -17% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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. Hazen Paper Company's 17.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hazen Paper Company against peers pursuing similar technology classes.
