Motor Control Patents: Top Companies & Filing Trends 2026
Motor control patents: who leads, where filing is slowing, and where the claim space is still open
13.3% concentration at the top. The five leading assignees hold 19,697 of 148,148 records in scope — a real lead, but nowhere close to lock-up. Annual filings ran from 784 in 2017 to a peak of 1,152 in 2018, then declined to 337 by 2024 — a 52% drop across the 2021-to-2024 window. Years from 2025 onward are still filling in and should not be read as a continued fall.

Common questions about the motor control patent landscape
Who holds the most motor control patents?
Filing in this corpus is led by a mix of diversified industrials and automotive-electronics suppliers, with the leading assignee holding 4,728 of the 148,148 records in scope. The gap from first to fifth place (3,302 records) and again to tenth (1,612) shows a step-down rather than a tight cluster, meaning no single company holds a dominant share. The top five combined account for 13.3% of all records, and the top ten for 20.4% — real leadership, but a long tail of smaller filers still covers the majority of the field.
Is motor control patent filing growing or shrinking?
Filings peaked in 2018 at 1,152 and have declined since, falling from 700 in 2021 to 337 in 2024 — a documented 52% drop across that window. Publication lag means 2025 and 2026 figures are still incomplete and should not yet be read as confirming a continued fall. Based on complete-year data, the trend through 2024 is a genuine pullback from the 2018 peak rather than steady growth.
What technology areas dominate motor control patents?
H02P, covering control of motors and generators, is the largest single class, appearing in 5.9% of all 148,148 records — more than triple the next most common class. Power conversion (H02M) and surgical/diagnostic applications (A61B) follow at around 1% each, with EV propulsion (B60L), electric motor hardware (H02K), and protective circuits (H02H) trailing further behind. Because a single record can carry several IPC classes, these percentages describe overlapping coverage rather than a strict partition of the field.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
