Wirtgen America, Inc. has been granted 8 US utility patents between 2017 and 2024, placing Wirtgen America, Inc. at rank #33,896 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.3 claims per patent with primary concentration in E01C (CONSTRUCTION OF, OR SURFACES FOR, ROADS, SPORTS GROUNDS, OR THE LIKE; MACHINES OR AUXILIARY TOOLS FOR CONSTRUCTION OR REPAIR). As a US Corporation, Wirtgen America, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Wirtgen sits between William Evans Retail Ltd (8 patents, rank #33,892) and Wood Stone Corporation (8 patents, rank #33,900) - the closest US assignees by grant volume. The composite Innovation Score of 32.0/100 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 4 grants, compared with 4 in the 2015–2019 window, a +0% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Wirtgen America, Inc.'s 12.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Wirtgen America, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Wirtgen's 8 grants land it in the top 60% 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.
