Reliance Industries Limited

Reliance Industries Limited (RIL) is a publicly traded Indian multinational conglomerate headquartered in Mumbai, Maharashtra. Founded in 1958 by Dhirubhai Ambani, RIL has grown to become India's largest public company by market capitalization and revenue, with a market capitalization of approximately $185 billion as of June 30, 2026, and trailing twelve-month revenues of $120 billion as of March 31, 2026. The company employs over 404,500 people as of March 31, 2026.

RIL operates a highly diversified portfolio of businesses spanning multiple sectors. Its core operations include hydrocarbon exploration and production, petroleum refining and marketing, and petrochemical manufacturing, notably operating the world's largest integrated, single-location refining complex in Jamnagar, India. Beyond energy, RIL is India's largest retailer, with extensive retail store formats, and a major player in telecommunications through Jio Platforms, offering Jio Fiber and Jio Mobile (Jio True 5G). The company also has significant interests in new energy, including solar energy systems, battery manufacturing, and hydrogen production, as well as media and entertainment, and financial services.

Reliance Industries Limited demonstrates an active, albeit limited, patent litigation posture as an operating company. The company has been involved in one tracked case, appearing as a plaintiff in a Patent Trial and Appeal Board (PTAB) proceeding. With zero defendant cases, this indicates RIL's focus on asserting or challenging patent rights rather than being a frequent target of infringement suits.

The single tracked case, "REC Solar Holdings AS et al. v. Maxeon Solar Pte Ltd.," filed on February 14, 2025, is an Inter Partes Review (IPR) at the PTAB. In this proceeding, Reliance Industries Limited, alongside REC Solar Holdings AS, is challenging a patent (US11251315B2) held by Maxeon Solar Pte Ltd. This patent pertains to TOPCon (Tunnel Oxide Passivated Contact) solar cell technology, aligning with RIL's strategic investments and operations in the new energy and solar sector.
