Portfolio overview

Brüel & Kjær Sound & Vibration Measurement A/s has been granted 7 US utility patents between 2015 and 2023, placing Brüel & Kjær Sound & Vibration Measurement A/s at rank #34,485 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.6 claims per patent with primary concentration in G01H (MEASUREMENT OF MECHANICAL VIBRATIONS OR ULTRASONIC, SONIC OR INFRASONIC WAVES). As a Foreign Corporation, Brüel & Kjær Sound & Vibration Measurement A/s is one of the more focused assignees in the PatentsView dataset. By volume, Brüel sits between BRP Finland OY (7 patents, rank #34,481) and BWDT, Llc (7 patents, rank #34,489) - the closest US assignees by grant volume. The composite Innovation Score of 33.8/100 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 1 grants, compared with 6 in the 2015–2019 window, a -83% 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. Brüel & Kjær Sound & Vibration Measurement A/s's 14.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Brüel & Kjær Sound & Vibration Measurement A/s against peers pursuing similar technology classes.
