Publicly traded Health Discovery Corporation (HDC) has sued Intel (6:20-cv-00666) over four pattern recognition patents identified as teaching “Support Vector Machine-Recursive Feature Elimination” (SVM-RFE) methods. Intel is accused of infringement through the provision of certain processors, Field Programmable Gate Arrays (FPGAs), Systems-on-Chip (SoCs), and software that are “tested, validated, verified, and optimized” allegedly using the “SVM-RFE” method. HDC and Intel have a history, with the Patent Trial and Appeal Board (PTAB) presiding over a near decade long interference between the two.
