Public register · revised 11 September 2026
Every grant in force naming Hemant K. Rohera as inventor, listed by jurisdiction with its grant number and date, so that any entry can be checked against the national register it came from.
How to read this register. Only grants that are in force are listed. Pending applications are named separately as pending, and filings that have lapsed or been abandoned are not listed at all, because a lapsed filing is not protection. Jurisdictions are named rather than counted: a count depends on what is included, while a list can be checked entry by entry.

| Eurasian — in force in Russia | EA 035682 | 24 Jul 2020 | In force |
The European grant is stated with its validation states rather than as "Europe" unqualified, because a European patent takes effect only in the states where it is validated. The Eurasian grant is stated the same way: EA 035682 is in force in Russia, having ceased in the other designated states.
A Power Generating System and Method for a Vehicle
PCT/IB2016/055563 · priority 25 September 2015. A power processing unit conditioning multiple onboard sources and routing traction power against a state-of-charge threshold, charging the store and driving the motor simultaneously.
| Jurisdiction | Grant number | Grant date | Status |
|---|---|---|---|
| India | IN 477613 | 6 Dec 2023 | In force |
| United States | US 11,117,476 | 14 Sep 2021 | In force |

| Eurasian — validated RU, KZ | EA 036594 | 27 Nov 2020 | In force |
The Japanese grant runs from a divisional application (2021-081109) of the parent — ordinary practice; the grant is what takes effect. A United States continuation, publication US 2024/0039430 A1, is pending.
Hybrid Power Pack · scope stated exactly
| Body | Report | Date | What was evaluated |
|---|---|---|---|
| Central Institute of Road Transport, Pune | B34000 | 20 Mar 2020 | Model HPP35A, cranking-battery life cycle: 10,000 cycles at 60 °C |
| DRDO R&DE (Engineers), Pune | 020623ESG/ETF | 21 Jun 2023 | Environmental discharge evaluation at +70 °C under sustained 450 A |
Both are single-configuration endurance and environmental evaluations. Neither was run against a battery-only control, and neither is a comparative life, efficiency or range measurement. The DRDO document is a test report — not a certification, endorsement or approval. Comparative type-testing to IEC 62619 and IEC 62133-2 against a defined duty cycle is the next stage. The full technical treatment is on the research page.
