Portfolio overview

Hamm Ag has been granted 92 US utility patents between 2015 and 2025, placing Hamm Ag at rank #3,918 across all assignees tracked by PlainPatent. This portfolio spans 46 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.3 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 Foreign Corporation, Hamm Ag is one of the more focused assignees in the PatentsView dataset. By volume, Hamm sits between Essenlix Corporation (92 patents, rank #3,914) and Institut National DE LA Recherche Agronomqiue (92 patents, rank #3,922) - the closest US assignees by grant volume. The composite Innovation Score of 54.0/100 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 41 grants, compared with 51 in the 2015–2019 window, a -20% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The Foreign 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. Hamm Ag's 13.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 46 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hamm Ag 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.
