Litigation

Phillip J. Wiese advises and defends clients on complex and rapidly evolving privacy and cybersecurity matters. He works with companies in the technology, retail, and healthcare sectors to navigate legal issues involving facial recognition, biometrics, wiretapping, artificial intelligence, and website tracking technologies, and he develops practical, creative strategies to resolve high-stakes privacy disputes. Phillip is certified by the International Association of Privacy Professionals (IAPP) as a Certified Information Privacy Professional for United States (CIPP/US).

Phillip counsels clients on compliance with data privacy and cybersecurity requirements, information security policies, and incident response planning. He advises clients regarding the California Consumer Privacy Act (CCPA) and other U.S. state privacy laws, the California Invasion of Privacy Act (CIPA), the Video Privacy Protection Act (VPPA), the Illinois Biometric Information Privacy Act (BIPA), state data breach notification statutes, and related federal and state regulations.

Phillip represents clients in federal and state courts at all stages of litigation, from early case assessment and
pre-trial strategy through trial and appeal. While he frequently resolves matters through favorable settlements, he is equally prepared to take cases to trial when the circumstances require.

Phillip maintains an active pro bono practice. His experience includes helping a transgender inmate obtain the first court-ordered sex reassignment surgery in the country and working with the ACLU to support indigent criminal defense efforts throughout California.

Prior to joining Coblentz, Phillip was an associate with Morgan Lewis in San Francisco.

Phillip is a member of the American Bar Association and serves on the Executive Committee of the Cybersecurity and Privacy Section of the San Francisco Bar Association.

Phillip earned his J.D., cum laude, from Northwestern University School of Law in 2013. While in law school, Phillip served as a judicial extern for Judge Virginia M. Kendall in the Northern District of Illinois. He received his B.S. in Journalism from Northwestern University in 2006.
