Portfolio overview

Dr. Hielscher Gmbh has been granted 11 US utility patents between 2015 and 2021, placing Dr. Hielscher Gmbh at rank #24,221 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.4 claims per patent with primary concentration in B06B (METHODS OR APPARATUS FOR GENERATING OR TRANSMITTING MECHANICAL VIBRATIONS OF INFRASONIC, SONIC, OR ULTRASONIC FREQUENCY, ; e.g.; FOR PERFORMING MECHANICAL WORK IN GENERAL). As a Foreign Corporation, Dr. Hielscher Gmbh is one of the more focused assignees in the PatentsView dataset. By volume, Dr. sits between Dolphin N2 Limited (11 patents, rank #24,217) and Dutton-lainson Company (11 patents, rank #24,225) - the closest US assignees by grant volume. The composite Innovation Score of 28.9/100 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 2 grants, compared with 9 in the 2015–2019 window, a -78% 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. Dr. Hielscher Gmbh's 13.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Dr. Hielscher 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.
