Dr. Yu has over ten years of experience in patent law, primarily focusing on patent prosecution and counseling. He drafts and prosecutes patent applications in a wide range of technologies across mechanical art and electrical art. 

Examples of the technologies in which Dr. Yu has expertise include light-emitting diode (LED) manufacturing apparatus and processes, telecommunications and networks (e.g., LTE, 4G, 5G New Radio), computer software (e.g., desktop and mobile applications, business methods), automotive (conventional cars, electrical cars, hybrid cars), heavy machinery (e.g., construction vehicles), optical imaging apparatus (e.g., scanners, printers, and cameras), information processing systems (e.g., encryption, decryption), medical and surgical devices (e.g., medical robotics, catheters, operational beds, ultrasonic scalpels), medical diagnostic and detection systems (e.g., patient health monitoring methods and apps), clean energy and renewables (e.g., solar cell, fuel cell, wind power), aerospace and aviation (e.g., airships), robotics (e.g., automated guided vehicle (AGV), drones), consumer products (e.g., vending machines, refrigerators, cosmetic product packaging, sports and fitness equipment), railroad technology, acoustics (e.g., speakers). 

Dr. Yu manages patent portfolios for clients ranging from start-ups to large corporations. He counsels clients on strategic planning of patent landscape and assists clients with patent portfolio development, especially for high-tech start-ups. He provides opinions on patentability, invalidity, non-infringement, and freedom-to-operate. Dr. Yu also has experience with post grant procedures, such as ex parte reexamination and inter partes review (IPR). 

While earning his Ph.D. degree in mechanical engineering at Penn State University, Dr. Yu worked as a research assistant in the Structural Dynamics and Controls Laboratory at the Center of Acoustics and Vibration. There he developed novel piezoelectric transducer networks coupled with electrical circuitry for controlling vibrations of turbine blades. During his undergraduate studies in China, Dr. Yu studied theories in mechanics, materials, and controls.
