Portfolio overview

Workhorse Group Inc. has been granted 60 US utility patents between 2018 and 2025, placing Workhorse Group Inc. at rank #5,727 across all assignees tracked by PlainPatent. This portfolio spans 27 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.6 claims per patent with primary concentration in B60K (ARRANGEMENT OR MOUNTING OF PROPULSION UNITS OR OF TRANSMISSIONS IN VEHICLES; ARRANGEMENT OR MOUNTING OF PLURAL DIVERSE PRIME-MOVERS IN VEHICLES; AUXILIARY DRIVES FOR VEHICLES; INSTRUMENTATION OR DASHB). As a US Corporation, Workhorse Group Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Workhorse sits between Wowza Media Systems, Llc (60 patents, rank #5,723) and [24]7.ai, Inc. (60 patents, rank #5,731) - the closest US assignees by grant volume. The composite Innovation Score of 63.7/100 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 59 grants, compared with 1 in the 2015–2019 window, a +5800% 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. Workhorse Group Inc.'s 18.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 27 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Workhorse Group Inc. against peers pursuing similar technology classes.

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.
