VANCOUVER, BC / ACCESS Newswire / June 4, 2026 / Redwood AI Corp. (CSE:AIRX)(OTCQB:RDWCF)(Frankfurt:Y0N, WKN: A422EZ) ("Redwood" or the "Company") is pleased to announce that it has filed a provisional patent application with the United States Patent and Trademark Office (USPTO) for technology related to an optimization module within Reactosphere, titled "Method of Chemical Experimental Optimization with Predictive-Accuracy-Based Sample-Size Planning." The filing represents an important step in protecting technology designed to support experimental planning, model-guided chemical optimization, and more efficient decision-making in chemistry-focused research and development activities.

The provisional patent application supports Redwood's intellectual property portfolio and relates to technology designed to address a practical challenge in chemical experimentation, namely determining how much initial experimental data may be needed before a predictive model can provide useful guidance. In many chemistry research and development activities, researchers must decide how many experiments to run based on available time, materials, cost, or laboratory capacity. Redwood's technology is designed to support a more structured approach by helping estimate whether a proposed experimental plan is likely to generate enough data to support reliable model-guided optimization.

The invention is intended to work as part of an integrated experimental planning and optimization workflow. At a general level, the technology aims to help researchers define an experimental space, plan an initial set of experiments, evaluate the expected usefulness of the resulting data, and then use experimental results to guide future recommendations. This approach is designed to help research teams make better use of laboratory resources by providing clearer insight into whether an experimental plan is likely to support meaningful predictive modelling before significant time and materials are committed.

By incorporating predictive-accuracy-based sample-size planning, Redwood believes the technology may help users avoid underpowered experimental plans that can lead to weaker model performance and less reliable recommendations. The system is designed to support situations where a researcher has a target level of predictive confidence and needs to estimate the number of experiments required, as well as situations where a researcher has a fixed experimental budget and needs to understand the likely modelling limitations of that dataset.

Redwood believes the technology may be applicable across a range of chemistry-driven industries, including pharmaceutical development, specialty chemicals, materials science, and defense-related chemistry applications where efficient experimental decision-making is important. The Company views the filing as part of its broader strategy to build and protect a differentiated AI-powered chemistry platform that supports practical, real-world research and development workflows.

"Chemical optimization can be one of the most time-consuming and resource-intensive parts of research and development. This patent filing is intended to protect technology designed to help researchers make better decisions before and during experimentation by connecting experimental planning with model-guided optimization. We believe this capability can strengthen Reactosphere's value as a practical platform for chemistry teams seeking to reduce unnecessary experimentation, improve the quality of their data, and move toward better outcomes more efficiently," said Louis Dron, CEO of Redwood AI.
