Programmable Logic Controller Expert Witnesses
Start Programmable Logic Controller Expert Search
A Programmable Logic Controller (PLC) is an industrial computer which is adapted for the control of manufacturing processes, such as assembly lines or robotic devices. A programmable logic controller expert witness is typically an electrical engineer or mechanical engineer with an advanced degree and extensive experience. Cahn Litigation Services is often called upon to locate expert witnesses that can support programmable logic controller matters to present evidence to support a case on behalf of the plaintiff or defendant.
Often, matters requiring product design expert witness services involve intellectual property, such as a patent infringement case or trade secrets dispute. A programmable logic controller subject matter expert could also be instrumental in a product liability case.
Litigation support by a programmable logic controller expert witness could include analysis, expert report, expert opinion, expert witness testimony, and trial testimony in court. In a high-profile case, or litigation involving a significant financial stake, counsel may request an engineer with prior expert witness experience. Programmable logic controller expert witnesses must have a deep understanding not only of the target technology, but also of the major players in the industry, market growth, market share, market dynamics, and competitive landscape. It is also essential that an expert witness possess the ability to provide expert testimony in such a manner that a jury and judge can understand the factual evidence.
Whether the case involves a distributed control system, microprocessor, industrial controls or industrial automation, Cahn Litigation Services has the experience required to turn an expert witness search around quickly and provide the right balance of expertise and testimony to support each unique project and its nuances.
