The verdict
Stion holds 11 US patents across 11 technology areas, rank #25,300 of 50,000 tracked assignees.
Stion Corporation has been granted 11 US utility patents between 2015 and 2015, placing Stion Corporation at rank #25,300 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.9 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a US Corporation, Stion Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Stion sits between Starpharma Pty Ltd. (11 patents, rank #25,296) and Strehl, Llc (11 patents, rank #25,304) - the closest US assignees by grant volume. The composite Innovation Score of 32.3/100 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 0 grants, compared with 11 in the 2015–2019 window, a -100% 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. Stion Corporation's 19.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Stion Corporation against peers pursuing similar technology classes.

How to use this portfolio
Stion's 11 grants land it in the top 59% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
