USPTO PatentsView assignee record - 192 granted patents across 33 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: G06F (ELECTRIC DIGITAL DATA PROCESSING).
The verdict
Quantum holds 192 US patents across 33 technology areas, rank #2,066 of 50,000 tracked assignees.
Quantum Corporation has been granted 192 US utility patents between 2015 and 2025, placing Quantum Corporation at rank #2,066 across all assignees tracked by PlainPatent. This portfolio spans 33 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.2 claims per patent with primary concentration in G06F (ELECTRIC DIGITAL DATA PROCESSING). As a US Corporation, Quantum Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Quantum sits between FMC Technologies, Inc. (192 patents, rank #2,062) and Zhejiang Sunny Optical Co., Ltd (192 patents, rank #2,070) - the closest US assignees by grant volume. The composite Innovation Score of 56.6/100 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 92 grants, compared with 100 in the 2015–2019 window, a -8% 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. Quantum Corporation's 18.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 33 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Quantum Corporation against peers pursuing similar technology classes.

How to use this portfolio
Quantum's 192 grants land it in the top 6% 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.
