Portfolio overview

Anaergia Inc. has been granted 33 US utility patents between 2015 and 2024, placing Anaergia Inc. at rank #9,424 across all assignees tracked by PlainPatent. This portfolio spans 30 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.3 claims per patent with primary concentration in C02F (TREATMENT OF WATER, WASTE WATER, SEWAGE, OR SLUDGE). As a Foreign Corporation, Anaergia Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Anaergia sits between Advanced Technology & Materials Co., Ltd. (33 patents, rank #9,420) and Ai Cure Technologies Llc (33 patents, rank #9,428) - the closest US assignees by grant volume. The composite Innovation Score of 44.0/100 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 12 grants, compared with 21 in the 2015–2019 window, a -43% 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. Anaergia Inc.'s 12.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 30 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Anaergia Inc. 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.
