Portfolio overview

Cnam—conservatoire National Des Arts At Metier has been granted 6 US utility patents between 2015 and 2020, placing Cnam—conservatoire National Des Arts At Metier at rank #39,397 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.0 claims per patent with primary concentration in C22F (CHANGING THE PHYSICAL STRUCTURE OF NON-FERROUS METALS AND NON-FERROUS ALLOYS). As a Foreign Corporation, Cnam—conservatoire National Des Arts At Metier is one of the more focused assignees in the PatentsView dataset. By volume, Cnam—conservatoire sits between CMMB Vision USA Inc. (6 patents, rank #39,393) and Cnsystems Medizintechnik Ag (6 patents, rank #39,401) - the closest US assignees by grant volume. The composite Innovation Score of 30.0/100 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 5 in the 2015–2019 window, a -80% 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. Cnam—conservatoire National Des Arts At Metier's 16.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Cnam—conservatoire National Des Arts At Metier against peers pursuing similar technology classes.
