Example cases requiring 3G expert witness service involve intellectual property, such as patent infringement litigation, inter partes review in the PTAB, or trade secret disputes. Forensic engineering of components can prove (or disprove) intellectual property infringement or theft. A 3G expert witness typically has an advanced degree and extensive experience in electrical engineering, wireless communication, software engineering, network architecture, and/or cellular networks.

3G is the third generation of wireless mobile telecommunication technology, with its predecessor being 2.5G and 2.5G GPRS networks. 3G provided faster access for applications in wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV. The first commercial 3G networks were introduced in mid-2001.

Its successor, 4G LTE technology, brought us increased data transfer speeds over 3G, and enabled the adoption of cloud and media streaming services, video conferencing, and a wide range Internet of Things devices. Today, wireless communication network technology is moving to 5G.

Litigation support by a 3G expert may include courtroom expert testimony, as well as other expert witness services including depositions, expert opinion, an expert report, infringement analysis, and related consulting activities. Clients may also seek a wireless industry expert for pre-litigation consulting work. In a high profile case, or litigation involving a significant financial stake, previous expert testimony experience is often a requirement. A 3G expert witness needs to not only have extensive knowledge in the subject, a wireless expert must also possess the ability to explain evidence to a jury.

Cahn Litigation Services has a vast network of experts and often receives calls from an attorney firm, typically litigators, to help locate a wireless network technology expert that can support cases involving 3G matters. At Cahn Litigation Services, sourcing wireless technology expert witnesses for patent litigation is a particular area of expertise.
