Multi-in-One Electric Drive Patents: Who Leads, Where the Gaps Are 2026
- Filing has already peaked. the trend rose to 24 records in 2022 and has since flattened, with 2026 figures still partial due to publication lag.
- The top of the field is thin. the top 5 assignees hold 39.9% of all 188 records, and the top 10 hold 56.9% — concentration exists, but a long tail of single- and few-filing entrants fills the rest.
- The IPC spread is unexpectedly broad. wireless communication (H04W) leads at 18.6% of records, ahead of body-fluid devices, digital processing and power conversion classes — a sign the search space spans several distinct engineering problems, not one tight cluster.
What the dataset covers
This landscape covers 188 published records matching multi-in-one electric drive integration terms — shared housing, cooling circuit design, electromagnetic compatibility, efficiency map improvement and volume reduction — filed between 2015 and mid-2026. The scope is defined by title and abstract/claim text matching rather than a single IPC class, which is why the resulting technology composition spans wireless communication, body-fluid devices, digital processing and power conversion subclasses rather than one dedicated drive-unit classification.
Coverage runs to the 2026-07-31 data cut-off. Because publication typically lags filing by around 18 months, the most recent one to two years of the trend understate actual filing activity and should be read as provisional.
Filing trend and technology composition
Two views of the same 188-record dataset: the year-by-year filing count, and the distribution of records across IPC subclasses. Because a single record can carry multiple IPC classes, the subclass shares add up to more than 100% of the record total.
Filings rose to a 2022 peak, then flattened
Annual filings climbed from 10 in 2017 to a peak of 24 in 2022, then leveled off. The 2026 figure of 2 is a partial-year count, not a genuine collapse — the 18-month publication lag means recent-year totals will keep rising as later filings publish.
Eight subclasses, no single dominant one
H04W (wireless communication networks) is the largest single subclass at 18.6% of the 188 records, followed by A61M and G06F tied at 9.6% each. No subclass clears 20%, meaning claim activity is dispersed across communication, sensing, digital-processing and power-conversion angles rather than concentrated on a drive-unit-specific classification.
Shares are the percentage of the 188 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Three findings a reader could not get from skimming the ranking table alone.
The top of the field is real but not dominant
The top 5 assignees combined account for 39.9% of all 188 records in scope, and the top 10 for 56.9%. That leaves close to half the dataset spread across a long tail of 46 further ranked assignees, many with only a handful of filings — the field has leaders but no single gatekeeper.
Growth has flattened since the 2022 peak
Filings rose steadily from 10 in 2017 to 24 in 2022, then plateaued. Recent-year momentum data for the leading assignees shows most at zero filings in the latest year, which combined with the flat trend suggests the current wave of filing has largely run its course — though publication lag means the newest filings are still arriving.
No single IPC subclass dominates
The largest subclass, H04W (wireless communication networks), covers only 18.6% of the 188 records. Power conversion (H02M), switches and relays (H01H), and protective circuit arrangements (H02H) each sit near 6%, meaning the field distributes claim activity across communication, protection and conversion functions rather than concentrating on one engineering axis.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to multi-in-one electric drive integration, with the prior art for and against each one.
Who is filing, and what is still open
The ranked list spans 56 companies counted by patent family, with filing concentrated among a handful of large-portfolio holders and a long tail of occasional filers.
One assignee holds the largest single share
The leading assignee in the ranking holds 28 of the 188 records — well ahead of the fifth-place holder at 10 — but still short of a majority, leaving room for challengers to build a comparable position through focused filing in the less-crowded subclasses.
The gap between first and fifth place is wide
Fifth place sits at 10 records, well under half the leader's count. That drop-off between the top assignee and the rest of the top 5 suggests the leading position was built early and has not been closely contested since.
Most assignees hold small, defensive-looking portfolios
Once the top 10 (56.9% of records) are set aside, the remaining assignees split the rest of the field in small increments — consistent with defensive or opportunistic filing rather than sustained platform investment.

Where to take this analysis
The ranking, trend and IPC breakdown answer the where and who. The next step is usually claim-level: what specific language is already occupied, and what is left to claim.

The ranking covers 56 companies counted by patent family, and the field is moderately concentrated: the top 5 assignees together hold 39.9% of all 188 records in scope, and the top 10 hold 56.9%. The leading assignee alone accounts for 28 records, well ahead of the fifth-place holder at 10, but the remaining 46 assignees in the ranking each hold small numbers of filings, so no single company controls the space outright. Anyone assessing freedom to operate should check both the top 10 and the specific sub-area they intend to claim, since concentration varies a lot by technical branch.
Filings rose from 10 in 2017 to a peak of 24 in 2022, then flattened. The 2026 count of 2 looks like a sharp drop, but that is mostly an artifact of the roughly 18-month lag between filing and publication — the most recent one to two years in any patent trend are always understated. Taken together, the pattern points to a filing wave that peaked in 2022 and has since plateaued rather than one that is still accelerating.
Based on IPC subclass distribution across the 188 records, the largest share sits in H04W (wireless communication networks) at 18.6%, followed by A61M (body fluid devices) and G06F (digital data processing) at 9.6% each, with H04L, H05K, H01H, H02H and H02M each between roughly 6% and 7.5%. Because a record can carry multiple IPC codes, these shares sum to more than 100% of the record total. The spread shows the search scope captures integration work touching communication, control electronics and power conversion rather than a single narrow drive-unit classification.
The IPC composition shows no subclass above 18.6% of records, and several specific sub-areas — shared-housing thermal isolation, EMC shielding at module boundaries, cooling-circuit efficiency mapping, volume-reduction packaging and cross-domain power-conversion protection — show comparatively low density relative to the core search terms. That does not guarantee an open field, since density alone does not capture claim scope, but it flags where a first claim is less likely to run into dense prior art immediately. Any white-space assessment should be followed by a claim-level check against the top assignees' existing filings before drafting.
The most-cited records in this corpus, including the lidar and photonic-integration filings at the top of the list, are older documents that have had more years to accumulate citations — not necessarily the most technically central patents to multi-in-one electric drive integration today. Citation count inside a searched corpus is a signal of historical influence and visibility, not of current importance to the field. For assessing what matters now, filing recency and claim scope are more reliable indicators than citation count alone.
