EV Powertrain LCA Patent Snapshot 2026
The patent corpus for EV powertrain life-cycle assessment contains only 2 patent families, split evenly between a single individual inventor and an academic foundation, making this one of the least-contested technical spaces in the broader EV domain. Activity is nascent and highly concentrated, with effectively no established corporate incumbents and wide-open adjacencies across every major IPC branch.
Two filers hold the entire known corpus — the field is essentially uncontested
The ranked applicant list comprises exactly two entities — NISHANT SHIVAJIRAO PATIL and the Ohio State Innovation Foundation — each holding one patent family, together accounting for the entire corpus.
The top five filers’ share of the ranked applicants visible in this query stands at 100%, reflecting a two-player corpus with no tier gap to speak of: there is no second tier at all. No automotive OEM, Tier-1 supplier, or major battery maker appears in the ranking.

The absence of corporate incumbents implies that the foundational IP positions in EV powertrain LCA methodology have not yet been claimed by the organizations most likely to eventually commercialize or regulate around them — leaving the field structurally open.
The two most recent filing years are subject to normal publication lag and may undercount actual activity; the true corpus size should be treated as a floor, not a ceiling. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Sporadic filings since 2023 and a narrow IPC footprint signal an early-formation stage
The annual trend and the technology-composition breakdown both point to a field that has only just begun to coalesce around formal patent protection. The two charts below show when activity appeared and which technical branches have been touched.
Annual filing trend
Filings were zero across every year from 2017 through 2022, with a single family appearing in 2023 and another in 2025. The 2024 and 2026 bars are subject to publication lag and should not be read as confirming zero activity in those years.

The visible IPC class is B60L (electric vehicle propulsion), which appears across both families. B32B (layered products and laminates), B60H (vehicle heating and. A/C), and H01M (batteries, cells, and fuel cells) each appear once, suggesting that the small corpus already touches thermal management and energy-storage sub-systems alongside core powertrain control.

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
NISHANT SHIVAJIRAO PATIL
An individual inventor holding 1 patent family, with a technology focus spanning B32B layered products and laminates, B60H vehicle heating and A/C, and B60L electric vehicle propulsion. Applicant momentum is flagged as a new entrant, consistent with the first filing appearing in 2025. The cross-branch focus suggests an interest in multi-material powertrain thermal architecture rather than a narrow control-algorithm approach.
families: 1Ohio State Innovation Foundation
The Ohio State Innovation Foundation holds 1 patent family concentrated entirely within B60L — specifically sub-classes covering electric vehicle propulsion control, energy supply, and battery monitoring (B60L15, B60L50, B60L58). No separate momentum trend is available beyond the single filing. As an academic technology-transfer entity, its route to commercialization would typically run through licensing rather than direct product development.
families: 1Frequently asked questions
The current corpus contains 2 patent families in scope, held by two separate applicants — one individual inventor and one academic foundation. This is an unusually small corpus and should be treated as a floor, since recent filings may not yet have published.
No corporate entity appears in the ranking. The two known filers are NISHANT SHIVAJIRAO PATIL (one patent family, filed in India) and the Ohio State Innovation Foundation (one patent family, filed in the United States). No automotive OEM, battery manufacturer, or Tier-1 supplier is present.
Based on the available trend data, the first filing appeared in 2023, with a second in 2025. No filings were recorded in any year from 2017 through 2022. The field has only just begun to generate formal patent activity.
Four IPC classes appear across the corpus: B60L (electric vehicle propulsion, present in both families), B32B (layered products and laminates), B60H (vehicle heating and A/C), and H01M (batteries, cells, and fuel cells). B60L is the visible class.
One family designates India and one designates the United States. Major EV markets including China, Germany, Japan, South Korea, and the European Patent Office are not represented in the current corpus.
The extremely small corpus and the absence of major corporate filers suggests a relatively open landscape, but a formal freedom-to-operate opinion requires full claim-level analysis of the two existing families (US20250353380A1 and IN202321015571A) as well as a broader prior-art search beyond this patent corpus. This landscape report identifies structural sparsity, not legal clearance.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
