His firm biography describes a practice that includes representing both plaintiffs and defendants in patent disputes. His work for plaintiffs has involved representing patent holding companies in litigation concerning technologies such as online dating and image compression. On the defense side, he has represented international manufacturers in lawsuits involving wireless communication standards like GSM, WCDMA, Wi-Fi, and Bluetooth, as well as manufacturers of other technology products. The single tracked case in the authoritative data, Vannisi et al. v. LiPang et al., was a defense representation.

Mr. Ni’s experience spans federal district courts and the International Trade Commission (ITC). While his firm profile lists a number of representative litigation matters resulting in favorable confidential settlements or findings of non-infringement, specific public details on verdicts or appeals are not available in the sources reviewed. There is no record of Mr. Ni appearing in inter partes review (IPR) or other post-grant proceedings before the Patent Trial and Appeal Board (PTAB) in publicly available data. In March 2025, the U.S. Patent and Trademark Office issued a public reprimand to Mr. Ni and placed him on probation for issues related to his trademark practice, specifically for violating USPTO trademark signature rules on a large number of applications for foreign-domiciled clients.

Prior to co-founding his current firm, Mr. Ni was an attorney at the national firms Patton Boggs, LLP, and McKool Smith, P.C. He earned his J.D. from The University of Texas School of Law in 2003 and was admitted to the Texas bar in 2004. He is also registered to practice before the U.S. Patent and Trademark Office.
