Portfolio overview

Walter Maschinenbau Gmbh has been granted 10 US utility patents between 2016 and 2024, placing Walter Maschinenbau Gmbh at rank #27,794 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.3 claims per patent with primary concentration in B23Q (DETAILS, COMPONENTS, OR ACCESSORIES FOR MACHINE TOOLS, e.g. ARRANGEMENTS FOR COPYING OR CONTROLLING ; MACHINE TOOLS IN GENERAL CHARACTERISED BY THE CONSTRUCTION OF PARTICULAR DETAILS OR COMPONENTS; CO). As a Foreign Corporation, Walter Maschinenbau Gmbh is one of the more focused assignees in the PatentsView dataset. By volume, Walter sits between Voxel Rad, Ltd. (10 patents, rank #27,790) and WEB Spark Ltd. (10 patents, rank #27,798) - the closest US assignees by grant volume. The composite Innovation Score of 31.9/100 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 3 grants, compared with 7 in the 2015–2019 window, a -57% 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. Walter Maschinenbau Gmbh's 15.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Walter Maschinenbau Gmbh 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.
