R&D & Intellectual Property

Su-vastika is serious about technology patents.

Invention isn't a slogan here — it's the business model. Su-vastika has filed 25 patents (11 already granted by the Indian Patent Office) across lithium energy storage, BESS, solar-hybrid power, IoT-based control and lift-rescue safety. Every granted patent below is backed by an official government certificate.

Why Patents Matter to Us

Built on invention, not imitation

Most of India's power-backup industry competes on price. Su-vastika competes on invention. Since 2019 the company has filed 25 patent applications — covering lithium Battery Energy Storage Systems (BESS), solar-hybrid power conditioning, intelligent battery equalization and management, IoT-based real-time monitoring, and emergency lift-rescue systems. 11 have already been granted by the Indian Patent Office; the rest are published and pending examination.

Our mentor, Kunwer Sachdev, holds the highest patent record in India's power backup and solar industry — the full story is at SolarManOfIndia.com.

We publish this record in full because intellectual property only matters if it can be checked. Every granted patent carries an official Indian Patent Office certificate (below), and every application number can be verified on the IPO public search portal. This is what taking R&D seriously looks like — protected, documented, and verifiable.
