Where does Ecole Polytechnique rank among US patent assignees?

According to USPTO PatentsView (2015–2025 granted utility patents), Ecole Polytechnique ranks #5,205 of 49,997 assignees by granted-patent volume, the same sort as the companies listing and top-holders ranking. See /methodology/#corpus-placement.

How many patents does Ecole Polytechnique hold?

Ecole Polytechnique holds 66 US utility patents granted between 2015 and 2025, spanning 63 technology areas.

What is Ecole Polytechnique's Innovation Score?

Ecole Polytechnique has an Innovation Score of 55.3 out of 100 (top 7% of the corpus). This composite metric weighs portfolio volume (40%), grant velocity (20%), technology breadth (25%), and claim depth (15%).

Is Ecole Polytechnique's patent grant rate increasing or decreasing?

Ecole Polytechnique's recent grant velocity is -39% compared to the prior five-year period (grant years, not application filing dates). Grant activity has slowed relative to earlier years.

What does claim depth mean for Ecole Polytechnique's patents?

Ecole Polytechnique's patents average 17.3 claims each. This is an aggregate descriptive count from the grant record; it does not establish claim scope, legal strength, enforceability, or design-around risk.

How is the Ecole Polytechnique patent data sourced?

All patent data comes from USPTO PatentsView, a public research dataset maintained by the United States Patent and Trademark Office covering US granted utility patents from 2015 to 2025.

What this shows Ecole's Innovation Score is 55.3/100 (top 7% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

How Ecole's grant cadence moved

Between 2020–2024, Ecole Polytechnique received 23 grants versus 38 in 2015–2019 (-39% equal-window velocity, below median growth). Across complete PatentsView years, output peaked in 2016 at 12 grants and bottomed in 2019 at 4. Lead class G01N accounts for 24.2% of the portfolio across 63 subclasses. Volume neighbours: Central Japan Railway Comany (#5,201) and HP Scitex Ltd. (#5,209).

Ecole's three-year grant acceleration

Ecole Polytechnique shows 12 grants in 2022–2024 against only 15 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
