Where does ECE rank among US patent assignees?

According to USPTO PatentsView (2015–2025 granted utility patents), ECE ranks #35,111 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 ECE hold?

ECE holds 7 US utility patents granted between 2015 and 2017, spanning 14 technology areas.

What is ECE's Innovation Score?

ECE has an Innovation Score of 27.2 out of 100 (23rd percentile of the corpus). This composite metric weighs portfolio volume (40%), grant velocity (20%), technology breadth (25%), and claim depth (15%).

What technology areas does ECE focus on?

ECE's top technology area is H02H (Emergency Protective Circuit Arrangements) with 2 patents, ranking #325 of 814 assignees active in that subclass. Grants appear in 14 CPC subclasses total.

Is ECE's patent grant rate increasing or decreasing?

ECE's recent grant velocity is -100% 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 ECE's patents?

ECE's patents average 11.3 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 ECE 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 ECE's Innovation Score is 27.2/100 (23rd percentile 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.

Does more volume mean deeper claims for ECE?

Each dot is one of ECE’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). ECE’s own 11.3 claims/patent is ABOVE the 10.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
