Portfolio overview

Entsorgafin S.p.a. has been granted 5 US utility patents between 2015 and 2021, placing Entsorgafin S.p.a. at rank #46,433 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.8 claims per patent with primary concentration in Y02W (CLIMATE CHANGE MITIGATION TECHNOLOGIES RELATED TO WASTEWATER TREATMENT OR WASTE MANAGEMENT). As a Foreign Corporation, Entsorgafin S.p.a. is one of the more focused assignees in the PatentsView dataset. By volume, Entsorgafin sits between Enscp—chimie Paristech—ecole Nationale Superieure DE Chime DE Paris (5 patents, rank #46,429) and Envistacom, Llc (5 patents, rank #46,437) - the closest US assignees by grant volume. The composite Innovation Score of 25.4/100 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. Between 2020 and 2025 the company received 1 grants, compared with 4 in the 2015–2019 window, a -75% 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. Entsorgafin S.p.a.'s 10.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Entsorgafin S.p.a. against peers pursuing similar technology classes.
