Ifti has litigated technical subject matter spanning myriad technology areas, including media servers, self-balancing smartboards, large-scale servers and databases, automotive design and parts, vision science and related telemedicine, polymer chemistry, and dental healthcare products. He has a proven capability to acclimate to and quickly become fluent in virtually all types of technical subject area, enabling him to operate effectively in a wide variety of patent and trade secret contexts.
