In the majority of smartphone/cell phone/mobile phone/mobile device matters that Cahn Litigation Services supports, the chosen expert witness has an advanced degree with extensive experience electrical engineering, cybersecuritywireless communicationcomputer science, computer forensicstelecommunications networks, software engineering, and/or cellular networks. A smartphone expert witness must possess the ability to explain technology and electronic evidence to lay people, such as a judge or juror. A smartphone expert witness should have an understanding not only of the technology, but also of the industry, market size, market share, market dynamics, market growth, market trends, and competitive landscape. In high profile cases, or litigation involving a significant financial stake, previous expert witness testimony experience is often a requirement.

Smartphone components include a central processing unit (CPU), display, sound/audio, batterycamera, accessories, and software (operating system and applications); and the credentials and background of a smartphone expert witness will vary depending on the specific technology in a litigation case. When a smartphone hits the market, the technology used could involve hundreds of thousands of patents. Samsung, Xiaomi, and Apple (iPhone) continue to dominate the global market. At Cahn Litigation Services, sourcing smartphone expert witnesses for patent litigation is a particular area of expertise.

Matters requiring smartphone technology expert witness services often involve intellectual property, such as patent infringement litigation or trade secrets. A subject matter expert in mobile phone technology could be called in to retrieve cell phone data or text messages to assist law enforcement. In a litigation scenario, an expert witness can expect courtroom testimony, as well as other expert witness services including reverse engineering, digital forensics, depositions, an expert report,  and related consulting activities. 

Cahn Litigation Services has a vast network of experts and often receives calls from an attorney firm, typically litigators, to help locate a technology expert that can support cases involving smartphone technology matters. Smartphone technology innovation continues to progress at an incredible pace, and it’s unlikely that the patent wars will slow down any time soon.
