Expert Witness #212686

This expert has many years of experience in software and hardware development for embedded systems, and has served as an Expert Witness. This expert has hands-on experience developing software on portable wireless communications devices, including the development of over 30 smartphone applications, generating over 50 million user installs. This expert has worked on numerous embedded systems projects which have included wireless communications, including game consoles, handheld gaming devices, first generation (J2ME/Brew) "feature" phones, present day smartphone devices and browser-based online games. As an expert in over 20 computer software languages, including assembly language [TMS1000, AMI S2000, 6502, 65816, 6800, Z80, 8080, etc], C, C++, Java, Javascript, Objective C, Lingo, Swift, and others, this expert has performed extensive source code analysis and reverse engineering from object code to source code. This expert has development experience with embedded systems utilizing ROM-based software. As an early pioneer in the handheld electronic toy and video game industries, this expert designed software on systems where the delivery mechanism was ROM-based cartridges. This expert also has strong knowledge of microprocessor and microcontroller architectures used in embedded systems, having designed the hardware and software of early microcontroller-based handheld electronic products. This expert designed, developed and coded one of the earliest tokenized interpretive languages for a commercially released software product. The architecture of the language was based on processor-independent, bytecode "object code," which was compiled on-the-fly during program design and interpreted in real-time by an assembly language-based virtual machine. The language was highly optimized, allowing for the development of real-time, graphic-intensive applications executing at 15 frames per second (on 8-bit hardware). This expert has been retained as an expert and accepted by the court in over 25 patent infringement cases, on both the plaintiff and defendant sides. This expert has written numerous reports on patent infringement and non-infringement, validity/invalidity and claim construction, been deposed over 25 times and has testified in court or at an arbitration hearing seven times. Outside of this expert's expertise in video games, this expert has worked on numerous other cases involving software development for general applications, including image processing, vector graphics, virtual reality, embedded control systems for location-based amusement machines, and a handheld language translator.
