As a patent agent, Dr. Yau performs various tasks related to patent prosecution including all aspects of preparing and prosecuting patent application as well as conducting novelty and infringement searches in Physics patents, Materials patents, and Engineering patents. His experience includes product evaluation, marketing photonic, electrical, sensor, biomedical, and nanotechnological devices. Dr. Yau is also the author of numerous publications, presentations and awarded proposals.

    Prior to joining Pillsbury, Dr. Yau worked as a patent agent for an Intellectual Property law firm. He handled patent prosecution in electronics such as:

    • Operation method and system of electronic device such as display device, computer system, etc,
    • various electronic devices (semiconductors, liquid crystal or organic light emitting display panel, touch panel, x-ray sensor array, etc.),
    • electronic materials (organic light emitting materials, doping of materials, rechargeable battery electrolyte component, active electrode materials, nano materials, etc.),
    • manufacturing methods and manufacturing apparatus (e.g. thin film deposition techniques, UV lithography, nozzle spraying, vacuum chamber, furnace, etc.),
    • circuitry (circuit design and components such as thermistor and stress sensing capacitor), and
    • mechanical engineering (e.g. computer stand, display frame, water distillation system, etc.), etc.
