USPTO PatentsView assignee record - 10 granted patents across 8 technology areas, active 2015–2020. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H01M (PROCESSES OR MEANS, e.g. BATTERIES, FOR THE DIRECT CONVERSION OF CHEMICAL ENERGY INTO ELECTRICAL ENERGY).
The verdict
Quallion holds 10 US patents across 8 technology areas, rank #27,207 of 50,000 tracked assignees.
Quallion Llc has been granted 10 US utility patents between 2015 and 2020, placing Quallion Llc at rank #27,207 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.8 claims per patent with primary concentration in H01M (PROCESSES OR MEANS, e.g. BATTERIES, FOR THE DIRECT CONVERSION OF CHEMICAL ENERGY INTO ELECTRICAL ENERGY). As a US Corporation, Quallion Llc is one of the more focused assignees in the PatentsView dataset. By volume, Quallion sits between Quixant Plc (10 patents, rank #27,203) and Quintar, Inc. (10 patents, rank #27,211) - the closest US assignees by grant volume. The composite Innovation Score of 29.6/100 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 9 in the 2015–2019 window, a -89% 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. Quallion Llc's 18.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Quallion Llc against peers pursuing similar technology classes.

How to use this portfolio
Quallion's 10 grants land it in the top 69% 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.
