System on Chip (“SoC”) is also referred to as a system-on-a-chip. It is an integrated circuit that contains many components of a larger system (like a computer, for example). A System on Chip expert witness must have a deep understanding, not only of the components, but also of the chip market, market share and the developing technologies of the industry’s leading players, such as Qualcomm, Samsung, IBM, Broadcom, Texas Instruments, Nokia and others that round out the field.
Typical SoC configurations can include a CPU, storage, signal processing, semiconductor memory blocks and I/O ports. They are often used in embedded systems found in smartphones and in other mobile computing devices.
Basic information on technology and SoC supply chain is available through a chip market report from Baker Tilly or another similar industry analysis provider. But a System on Chip expert witness must have a deeper understanding of the chip market, the history, the progression of the technology and often an understanding of which competitors were working on various designs at different points of time during the initial development stage.
As technologies have progressed and evolved over the years, other types of semiconductor systems performing similar tasks, have landed in the same general space as the System on Chip. A consulting expert would typically be an electrical engineer with an advanced degree, familiar with computer science and possessing extensive experience in semiconductors to contrast the SoC with the ASIC, ASSP, and FPGA. And while many competent consultants have the basic knowledge to get that part of the job done, the expert witness carries the additional responsibility of providing testimony before the court, in a manner whereby lay people (the judge and every juror) can understand the technical nuances, such to make an informed decision.
An expert witness in this field will typically provide his or her expertise in intellectual property matters — a patent litigation in the federal court. It could be a patent infringement case in the District Court, an Inter Partes Review (IPR) in the PTAB (where the only expert testimony is through a deposition), or a patent case or proceeding in the International Trade Commission (ITC). Less frequently, an expert of this kind might provide testimony in a torts matter like a personal injury case involving the failure analysis of a consumer electronics or medical device.
A testifying expert, or expert witness, is generally the only one in the court who is allowed to provide testimony as to his or her opinion — because it is an expert opinion. Regardless of whether this takes the form of testimony in a deposition or trial, or in an expert report, the engineering component will provide credibility to his or her analysis and allow the jury to consider the expert’s opinion with the weight it deserves.
