The verdict
Pruftechnik holds 9 US patents across 9 technology areas, rank #29,764 of 50,000 tracked assignees.
Pruftechnik Dieter Busch Ag has been granted 9 US utility patents between 2015 and 2017, placing Pruftechnik Dieter Busch Ag at rank #29,764 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.7 claims per patent with primary concentration in G01B (MEASURING LENGTH, THICKNESS OR SIMILAR LINEAR DIMENSIONS; MEASURING ANGLES; MEASURING AREAS; MEASURING IRREGULARITIES OF SURFACES OR CONTOURS). As a Foreign Corporation, Pruftechnik Dieter Busch Ag is one of the more focused assignees in the PatentsView dataset. By volume, Pruftechnik sits between Project Affinity, Inc. (9 patents, rank #29,760) and PTC Innovations, Llc (9 patents, rank #29,768) - the closest US assignees by grant volume. The composite Innovation Score of 26.8/100 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 0 grants, compared with 9 in the 2015–2019 window, a -100% 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. Pruftechnik Dieter Busch Ag's 13.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Pruftechnik Dieter Busch Ag against peers pursuing similar technology classes.

How to use this portfolio
Pruftechnik's 9 grants land it in the top 79% 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.
