Prof. Mehdi's U.S. Patent Granted for EMG-Based Neuromuscular Diagnosis

An important research milestone from Prof. Mehdi Hasan Chowdhury’s earlier CALAS work has now been formally recognized with a granted U.S. patent. According to the public U.S. patent record, U.S. Patent No. 12,539,070 B2, titled “Perceptron-based EMG processor for neuropathy and myopathy diagnosis”, was granted on February 3, 2026.

The public patent record lists the inventors as Mehdi Hasan Chowdhury, Ray Chak Chung Cheung, Muhammad Irfan, Abdurrashid Ibrahim Sanka, and Siu Ying Patrick Hung, with City University of Hong Kong as the assignee. The application was filed on September 23, 2021, reflecting several years of sustained work from initial filing to final grant.

This patent highlights meaningful progress in biomedical hardware design, particularly in developing a hardware-friendly point-of-care framework for distinguishing between neuropathy and myopathy using EMG signals. It is a strong example of how research in reconfigurable computing and health technology can translate into protected intellectual property with practical value.

As Prof. Ray noted, quality work takes time, and this achievement is a good reminder that long-term planning and persistence matter in research and innovation. Congratulations to Prof. Mehdi and the full inventor team on this well-deserved U.S. patent grant.
