Interdigital Technology Corporation & Ors. v. Guangdong Oppo Mobile Telecommunications Corp. Ltd. & Ors.

In the high-stakes world of standard-essential patents (SEPs), the most valuable evidence isn't always the patent itself—it's the secret deals struck around it. When a confidential Patent License Agreement (PLA) becomes the linchpin of a billion-dollar dispute, can a third party successfully keep it hidden from the very parties fighting over its terms? A recent ruling in the InterDigital vs. Oppo battle answered that question with a resounding "no"—and reshaped what founders need to understand about confidentiality in patent litigation.

The dispute unfolded between InterDigital Technology Corporation and Guangdong Oppo Mobile, a clash rooted in the complex world of standard-essential patents and FRAND (Fair, Reasonable, and Non-Discriminatory) licensing. At the heart of the controversy was a Patent License Agreement dated 1st June, 2014, originally signed between Samsung Electronics and the InterDigital Group Companies. Samsung, though not a direct party to the InterDigital vs. Oppo fight, had a powerful interest in keeping the terms of that 2014 agreement under wraps. The court had established a confidentiality club to manage sensitive documents in the case, and the question became: should the PLA be shared with Oppo's in-house representatives inside that club? Samsung intervened aggressively, arguing that disclosure would expose commercially sensitive terms to a direct competitor and undermine the very purpose of confidentiality protections.

Samsung Electronics argued forcefully that the PLA contained commercially sensitive terms that, if disclosed—even within a tightly controlled confidentiality club—would cause irreparable competitive harm. The company insisted that Oppo's in-house representatives, as employees of a direct rival in the mobile technology space, could not be trusted with such sensitive information, regardless of any safeguards. On the other side, the defendants (including Oppo) contended that the PLA was essential to fairly adjudicating the SEP/FRAND dispute at hand. Without access to the actual licensing terms Samsung had agreed to, they argued, they could not meaningfully assess whether InterDigital's offers to them were truly FRAND-compliant. The legal friction was clear: Samsung's right to commercial secrecy versus the defendants' right to a fair hearing on critical evidence.

On 14 October, 2024, the court sided with the need for fair adjudication. The court ultimately directed that the Patent License Agreement must be shown to the defendants' representatives, subject to specific restrictions designed to balance both interests. While the court did not ignore Samsung's concerns about confidentiality, it ruled that the necessity of disclosure for proper adjudication outweighed absolute secrecy. The outcome was plaintiff-favorable, meaning InterDigital's position was strengthened by the disclosure—because the PLA's terms would now serve as a benchmark in evaluating the FRAND nature of InterDigital's licensing offers to Oppo. The court's reasoning reflected a pragmatic principle: in SEP/FRAND disputes, comparable license agreements are often indispensable evidence, and confidentiality clubs exist precisely to enable controlled disclosure rather than to block it entirely.

For founders, IP professionals, and startup leaders operating in technology spaces governed by standard-essential patents, this case delivers a critical lesson: confidential third-party agreements can and will be disclosed by courts when necessary for fair adjudication. If your business model depends on SEP licensing or you are entering into Patent License Agreements, do not assume that confidentiality clauses will shield those deals from judicial scrutiny in related disputes. Build your legal strategy with the assumption that comparable license terms may eventually be exposed to competitors under court-supervised safeguards. More importantly, structure your confidentiality clubs and protective orders proactively—anticipating that "specific restrictions" will be the court's
