Portfolio overview

Ecole Superieure DE Chimie Physique Electronique DE LYON has been granted 7 US utility patents between 2015 and 2025, placing Ecole Superieure DE Chimie Physique Electronique DE LYON at rank #35,103 across all assignees tracked by PlainPatent. This portfolio spans 22 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.4 claims per patent with primary concentration in C08F (MACROMOLECULAR COMPOUNDS OBTAINED BY REACTIONS ONLY INVOLVING CARBON-TO-CARBON UNSATURATED BONDS). As a Foreign Corporation, Ecole Superieure DE Chimie Physique Electronique DE LYON is one of the more focused assignees in the PatentsView dataset. By volume, Ecole sits between Eckerle Technologies Gmbh (7 patents, rank #35,099) and Edgewater Wireless Systems Inc. (7 patents, rank #35,107) - the closest US assignees by grant volume. The composite Innovation Score of 39.7/100 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 6 grants, compared with 1 in the 2015–2019 window, a +500% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Ecole Superieure DE Chimie Physique Electronique DE LYON's 15.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 22 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ecole Superieure DE Chimie Physique Electronique DE LYON against peers pursuing similar technology classes.
