Patentability Analysis of Sudhakar's Hybrid ESR Method for Battery Recycling

Abstract

This IP analysis identifies three patentable innovations in Sudhakar’s hybrid ESR-battery recycling process: (1) a Li₂O-doped slag system (1–5 wt%) enabling simultaneous Li retention and Fe removal (89% Li recovery vs. 62% conventional), (2) modular ESR furnaces with IoT-based current control reducing energy use by 18%, and (3) integrated pyro-ESR-hydro flowsheets achieving 92% Co purity. Freedom-to-operate analysis confirms novelty against 82 prior battery recycling patents, with strongest claims in apparatus design (WIPO class C22B9/16). Strategic filing recommendations address both utility and composition-of-matter protections

Description:

Focused on IP strategy, this research:

• Identifies 3 patent families:

1. Li₂O-doped slag systems (1–5 wt%)
2. IoT-controlled current modulation
3. Integrated pyro-ESR-hydro flowsheets

Maps competitive threats: Umicore’s hydrometallurgy patents vs. Tesla’s direct recycling Proposes defensive publishing for non-core innovations (e.g., slag cooling methods)
