Where does EMPA rank among US patent assignees?

According to USPTO PatentsView (2015–2025 granted utility patents), EMPA ranks #26,222 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 EMPA hold?

EMPA holds 10 US utility patents granted between 2017 and 2022, spanning 16 technology areas.

What is EMPA's Innovation Score?

EMPA has an Innovation Score of 36.6 out of 100 (top 46% of the corpus). This composite metric weighs portfolio volume (40%), grant velocity (20%), technology breadth (25%), and claim depth (15%).

What technology areas does EMPA focus on?

EMPA's top technology area is Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution) with 7 patents, ranking #1,663 of 5,963 assignees active in that subclass. Grants appear in 16 CPC subclasses total.

Is EMPA's patent grant rate increasing or decreasing?

EMPA's recent grant velocity is -75% 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 EMPA's patents?

EMPA's patents average 19.9 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 EMPA 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 EMPA's Innovation Score is 36.6/100 (top 46% 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 EMPA?

Each dot is one of EMPA’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). EMPA’s own 19.9 claims/patent is ABOVE the 14.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where EMPA's grants concentrate

EMPA is a focused PatentsView assignee: 16 CPC subclasses with 70% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2020. By volume, EMPA sits between Electro Terminal GMBH & Co KG and ENN Science AND Technology Development Co., Ltd.

EMPA's three-year grant acceleration

EMPA shows 1 grants in 2022–2024 against only 3 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.
