Portfolio overview
Cambridge Sound Management, Inc. has been granted 11 US utility patents between 2015 and 2023, placing Cambridge Sound Management, Inc. at rank #24,108 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.2 claims per patent with primary concentration in H04R (LOUDSPEAKERS, MICROPHONES, GRAMOPHONE PICK-UPS OR LIKE ACOUSTIC ELECTROMECHANICAL TRANSDUCERS; DEAF-AID SETS; PUBLIC ADDRESS SYSTEMS). As a US Corporation, Cambridge Sound Management, Inc. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 34.5/100 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 5 grants, compared with 6 in the 2015–2019 window — a -17% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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. Cambridge Sound Management, Inc.'s 19.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Cambridge Sound Management, Inc. against peers pursuing similar technology classes.
