Jiaxiao "Jason" Zhang

Jiaxiao "Jason" Zhang is an Of Counsel attorney at Womble Bond Dickinson (US), where his patent litigation practice focuses on representing plaintiffs in intellectual property disputes. His experience, as evidenced by his tracked case, involves complex technology related to advertising technology and cross-device tracking.

His primary experience to date includes serving as Of Counsel for Intent IQ LLC in their patent infringement litigation against Viant Technology LLC. This case specifically addresses methods and computer systems for measuring ad effectiveness across devices by correlating online devices with set-top boxes to enable targeted television advertising.

While no direct PTAB appearances are explicitly attributed to Mr. Zhang in the search results, the Intent IQ LLC v. Viant Technology LLC matter has generated significant activity before the Patent Trial and Appeal Board (PTAB). Several inter partes review (IPR) proceedings have been filed against Intent IQ LLC's patents involved in the litigation, including IPR2026-00330, IPR2025-00128, and IPR2024-00421. One IPR resulted in a finding of unpatentability for challenged claims and is currently on appeal to the Federal Circuit. His representation of the patent owner in related district court litigation indicates his practice encompasses matters subject to active post-grant review.

Mr. Zhang is admitted to practice in California.
