Where does SEM AB rank among US patent assignees?

According to USPTO PatentsView (2015–2025 granted utility patents), SEM AB ranks #20,386 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 SEM AB hold?

SEM AB holds 14 US utility patents granted between 2015 and 2025, spanning 12 technology areas.

What is SEM AB's Innovation Score?

SEM AB has an Innovation Score of 39.4 out of 100 (top 38% of the corpus). This composite metric weighs portfolio volume (40%), grant velocity (20%), technology breadth (25%), and claim depth (15%).

Is SEM AB's patent grant rate increasing or decreasing?

SEM AB's recent grant velocity is -50% 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 SEM AB's patents?

SEM AB's patents average 13.1 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 SEM AB 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 SEM's Innovation Score is 39.4/100 (top 38% 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 SEM?

Each dot is one of SEM’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). SEM’s own 13.1 claims/patent is at or below the 13.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where SEM's grants concentrate

SEM AB is a focused PatentsView assignee: 12 CPC subclasses with 78.6% of grants classified under F02P (Ignition, Other Than Compression Ignition, FOR Internal-combustion ENGINES; Testing OF Ignition Timing IN Compression-ignition Engines). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2015. By volume, SEM sits between Scivax Corporation and Sernet (SUZHOU) Technologies Corporation.

SEM's three-year grant acceleration

SEM AB shows 3 grants in 2022–2024 against only 2 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.
