Portfolio overview

Amril Ag has been granted 5 US utility patents between 2016 and 2020, placing Amril Ag at rank #44,539 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.6 claims per patent with primary concentration in C08K (Use of inorganic or non-macromolecular organic substances as compounding ingredients). As a Foreign Corporation, Amril Ag is one of the more focused assignees in the PatentsView dataset. By volume, Amril sits between AMP Llc (5 patents, rank #44,535) and Anadolu Universitesi Rektorlugu (5 patents, rank #44,543) - the closest US assignees by grant volume. The composite Innovation Score of 30.3/100 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. Amril Ag's 16.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 16 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Amril Ag against peers pursuing similar technology classes.

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.
