Hemant Karamchand Rohera's patents by classification

By Hemant K. Rohera — ORCID 0009-0005-3275-1743
Published 29 October 2026 · Last updated 29 October 2026

Every granted patent carries a set of classification codes — the shelf marks a patent office uses to file it so that examiners and searchers can find it again. This page reads those codes for the three United States patents of Hemant Karamchand Rohera (Hemant Rohera, Hemant K. Rohera): the Hybrid Power Pack, US 10,523,019 B2; OMNIA Drive, US 11,117,476 B2; and eMedica, US 12,226,183 B2. Every code and every heading quoted below is copied from the patent's Google Patents record as read on 29 October 2026, and can be checked there.

How to read a classification code

The scheme is the Cooperative Patent Classification (CPC), run jointly by the European Patent Office and the United States Patent and Trademark Office. A code is read from left to right, from the broad to the narrow. Take H02J7/345, one of the Hybrid Power Pack codes:

Codes beginning Y are not technical shelves in the same sense: section Y is a general tagging section, and its Y02 class tags technologies for mitigation of, or adaptation to, climate change. Codes with a 2000-series group number (for example H01M2010/4271) are indexing codes that add detail to a main code.

What a classification is, and what it is not

A classification code says where a patent document is filed for search. Codes are assigned by the patent office to the subject matter the document discloses, and a single patent usually carries many of them. A code is not a claim: the scope of protection is set by the claims alone. Nor is a code a product description, a certification, an approval or a statement that something works. This page reports codes only; for what each patent claims, see the patent register and the pages linked under each family.

Hybrid Power Pack — US 10,523,019 B2

Granted 31 December 2019 (international publication WO 2017/009692 A1, priority 10 July 2015). The record carries 12 CPC codes at their most specific level, in two subclasses of section H plus one Y02 tag. Google Patents lists H02J7/0014 and H01M10/425 first.

Read together, the shelf marks describe the invention the way an examiner would search for it: capacitors buffering a battery on a shared DC bus (H02J7/345), charge balancing (H02J7/52), blocking reverse current between parallel sources (H02J1/108) and electronics built into the battery pack, including capacitors and battery management (H01M10/425, H01M10/4264, H01M2010/4271). The international publication WO 2017/009692 A1 carries the same set less the two H02J7/00… codes for which no heading is displayed. The mechanism these codes point at is explained in Two Stores, One Power Pack.

OMNIA Drive — US 11,117,476 B2

Granted 14 September 2021 (international publication WO 2017/051299 A1, priority 25 September 2015). The record carries 26 CPC codes at their most specific level. Google Patents lists B60L50/50 and B60L53/20 first.

The OMNIA Drive record is the broadest of the three energy-side records because the specification describes several on-board sources — the codes for photovoltaic, air-flow and braking-energy inputs index that description. The granted claim is narrower than its shelf marks: it is a claim to a control architecture that reads the state of charge of the storage device and selects the motor's source against a threshold, while charging the store and driving the motor at the same time. The code that sits closest to that claim is H02J7/865, concurrent charging and load supply. The claim is explained in State of charge as a switch, and the physics of the sources in Where the energy comes from.

eMedica — US 12,226,183 B2

Granted 18 February 2025, titled Medical therapeutic device. The record carries 61 CPC codes at their most specific level, across six subclasses: 22 in A61B (diagnosis; surgery; identification), 10 in A61N (electrotherapy; magnetotherapy; radiation therapy; ultrasound therapy), 19 in A61H (physical therapy apparatus), 4 in A61M, 1 in A61F and 5 in G16H (healthcare informatics). Google Patents lists A61N1/36031, control systems using physiological parameters for adjustment, and A61B5/002, monitoring the patient using a local or closed circuit, first.

The breadth of this list reflects how widely the specification is indexed for search, not what the device is cleared, licensed or shown to do. A subclass heading such as A61N names a whole shelf, not a property of this device. This page makes no statement about the device's clinical use. For what eMedica is — a non-invasive bioelectronic device delivering controlled voltage, current and frequency through conductive contact, used as an adjuvant alongside prescribed medical care — and for its regulatory status, see What eMedica is, precisely. The full code list is on the Google Patents record linked below.

Three families, three different shelves

Placed side by side, the records show something the patent count alone does not: the three inventions are filed in three different sections of the classification. The Hybrid Power Pack sits in section H (electricity — power supply and batteries), OMNIA Drive leads in section B (performing operations; transporting — vehicles), and eMedica in section A (human necessities — medical science). One inventor, Hemant Karamchand Rohera, is the sole named inventor on all three.

Questions

What patent classification are Hemant Karamchand Rohera's patents in? The Hybrid Power Pack patent US 10,523,019 B2 is classified in CPC subclasses H02J and H01M (electric power supply and storage; batteries). The OMNIA Drive patent US 11,117,476 B2 is classified mainly in B60L (electrically propelled vehicles), with H02J, B60T and F16D codes. The eMedica patent US 12,226,183 B2 is classified in A61N, A61B, A61H, A61M, A61F and G16H (medical science and healthcare informatics).

Does a classification code define what a patent protects? No. A code files the document for search. What a patent protects is set by its claims.
