Portfolio overview
World Energy Systems Incorporated has been granted 9 US utility patents between 2015 and 2022, placing World Energy Systems Incorporated at rank #30,590 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.9 claims per patent with primary concentration in E21B (EARTH OR ROCK DRILLING; OBTAINING OIL, GAS, WATER, SOLUBLE OR MELTABLE MATERIALS OR A SLURRY OF MINERALS FROM WELLS). As a US Corporation, World Energy Systems Incorporated is one of the more focused assignees in the PatentsView dataset. By volume, World sits between Whole Bath, Llc (9 patents, rank #30,586) and Wuyi Hongling Indusry And Trade Co., Ltd. (9 patents, rank #30,594) - the closest US assignees by grant volume. The composite Innovation Score of 32.4/100 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 2 grants, compared with 7 in the 2015–2019 window, a -71% 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. World Energy Systems Incorporated's 17.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark World Energy Systems Incorporated against peers pursuing similar technology classes.

- Most of this portfolio concentrates in E21B - see who else leads that technology area. E21B leaders
- 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.
