Unified Patents Approved for OpenAI Zero Data Retention; Equivalent Zero-Retention Configuration Confirmed for Gemini

Unified Patents, LLC secured approval from OpenAI for Zero Data Retention (ZDR) following an individual review process. ZDR removes OpenAI’s standard API log retention for our approved use cases. In parallel, our Gemini integrations on Google Cloud are configured for an equivalent zero-retention posture, including disabling context caching and avoiding features that store prompts or responses. These additional protections apply to Unified’s Portal tools: Pearl, Precision, and Ask Patty.

To our members, customers, and users in the legal community: we built these controls to reinforce the confidentiality. With these zero retention configurations, provider systems do not retain the prompts or outputs our tools send for approved endpoints and configurations—and neither provider uses our API data to train their models. These measures complement our internal safeguards and procedures designed to protect work product.

What this means for you

  • Zero provider-side retention by OpenAI: OpenAI does not retain inputs or outputs.

  • Gemini set to zero retention: Our Gemini integrations are configured to avoid provider retention (e.g., disabling context caching) and to exclude stored modes that could keep data.

  • No training on our business/API data: Our AI usage is implemented so that model providers do not use our prompts or responses to train their models.

  • Aligned with confidentiality: Our approach is designed to minimize provider-side exposure and help maintain the confidentiality of sensitive matters.

Defensive Alliance to Shield AI Companies from Patent Troll Litigation

Unified Patents is happy to launch the Artificial Intelligence (AI) Zone. This new Zone will deter patent abuse and bring together a large and growing network of members to address non-practicing entities that assert vague software patents.

The Zone combines ex parte reexamination challenges, litigation trend monitoring, ownership intelligence, prior‑art workflows, and USPTO challenges to change trolls’ cost–benefit calculus across AI domains.

Members gain access to shared data on litigation trends, patent ownership changes, and aggressive actors in the AI patent space. As part of the AI Zone, Unified Patents has developed the first-ever GenAI patent landscape.  This landscape, OPAL for GenAI, will help companies identify and mitigate risk, plan their legal strategies, grow their portfolios, and understand their own value.

This tool, available exclusively to the members of Unified Patents’ new Zone, allows for a new way to identify and value patents, analyze risk, and determine the total top-down patent landscape quickly and easily—and be more prepared and better value the competition and litigations of tomorrow.
