About Us


Roaring Fork Research helps professional investors identify and stay on top of intellectual property disputes that may have a material impact on public companies. We use proprietary data analytics to pinpoint signal from noise across all global patent litigation. While the vast majority of patent disputes are immaterial to investors, certain cases present a legitimate risk or opportunity for a public company. We shed light on such cases — illuminating complex situations and environments, and prepping the investor for a range of outcomes.
