USPTO PatentsView assignee record - 137 granted patents across 54 technology areas, active 2018–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: E21C (MINING OR QUARRYING).
The verdict
Joy holds 137 US patents across 54 technology areas, rank #2,809 of 50,000 tracked assignees.
Joy Global Underground Mining Llc has been granted 137 US utility patents between 2018 and 2025, placing Joy Global Underground Mining Llc at rank #2,809 across all assignees tracked by PlainPatent. This portfolio spans 54 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.2 claims per patent with primary concentration in E21C (MINING OR QUARRYING). As a US Corporation, Joy Global Underground Mining Llc is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Joy sits between HI Llc (137 patents, rank #2,805) and Salomon S.a.s. (137 patents, rank #2,813) - the closest US assignees by grant volume. The composite Innovation Score of 56.8/100 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 89 grants, compared with 48 in the 2015–2019 window, a +85% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Joy Global Underground Mining Llc'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 54 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Joy Global Underground Mining Llc against peers pursuing similar technology classes.

How to use this portfolio
Joy's 137 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.
