USPTO PatentsView assignee record - 66 granted patents across 63 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: G01N (INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES).
The verdict
Ecole holds 66 US patents across 63 technology areas, rank #5,205 of 50,000 tracked assignees.
Ecole Polytechnique has been granted 66 US utility patents between 2015 and 2025, placing Ecole Polytechnique at rank #5,205 across all assignees tracked by PlainPatent. This portfolio spans 63 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.3 claims per patent with primary concentration in G01N (INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES). As a Foreign Corporation, Ecole Polytechnique is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Ecole sits between Central Japan Railway Comany (66 patents, rank #5,201) and HP Scitex Ltd. (66 patents, rank #5,209) - the closest US assignees by grant volume. The composite Innovation Score of 55.3/100 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 28 grants, compared with 38 in the 2015–2019 window, a -26% 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. Ecole Polytechnique's 17.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 63 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ecole Polytechnique against peers pursuing similar technology classes.

How to use this portfolio
Ecole's 66 grants land it in the top 7% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
