Portfolio overview

Environmental Dynamics International, Inc. has been granted 8 US utility patents between 2015 and 2023, placing Environmental Dynamics International, Inc. at rank #31,516 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.1 claims per patent with primary concentration in C02F (TREATMENT OF WATER, WASTE WATER, SEWAGE, OR SLUDGE). As a US Corporation, Environmental Dynamics International, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Environmental sits between ENK Wireless, Inc. (8 patents, rank #31,512) and Epalex Corporation (8 patents, rank #31,520) - the closest US assignees by grant volume. The composite Innovation Score of 39.9/100 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 2 grants, compared with 6 in the 2015–2019 window, a -67% 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. Environmental Dynamics International, Inc.'s 17.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Environmental Dynamics International, Inc. against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
