Timothy Tiewei Wang

Practice focus and side. Timothy ("Tim") T. Wang is a Dallas-based IP litigator and partner at Ni, Wang & Massand, PLLC, a boutique intellectual-property firm. His litigation docket centers on district-court patent disputes over imported consumer products — LED/solid-state lighting, consumer electronics, and e-commerce goods — frequently involving Chinese manufacturers and importers defending against U.S. patent holders. His two tracked appearances are both defense-side (Elong International USA, Inc. and Xiamen Longstar Lighting Co.), and publicly available dockets show comparable defense work for companies such as RugGear GmbH, alongside plaintiff-side enforcement matters (e.g., Netvue Technologies, Semisilicon). I found no evidence of pharma, biotech, or standard-essential-patent (Wi-Fi/SEP) work.

Firm context and notable matter. Wang has practiced at Ni, Wang & Massand since at least 2013 (records show him at the firm in cases from 2013 through 2026), with a practice the USPTO has described as focused primarily on IP litigation plus a large foreign-domiciled trademark prosecution docket (he was attorney of record on ~2,987 USPTO trademark applications as of August 2024). His most prominent tracked matter is Feit Electric Co. v. Elong International USA, Inc. et al. (3:24-cv-01089, N.D. Tex.), where he appeared as counsel of record for Elong and Xiamen Longstar in a dispute over Feit's LED-filament patent (U.S. 8,604,678). That case ended in a joint dismissal without prejudice in January 2026, with no merits ruling. The dispute also generated parallel PTAB proceedings, including IPR2024-01357 (instituted March 2025) and IPR2025-00258, whose Director-level denial — involving joinder and discretionary-denial timing — was designated precedential in January 2026.

PTAB/IPR exposure. Wang does not appear regularly as lead counsel in IPR/PGR petitions based on available records; his PTAB footprint is mostly indirect — service/contact listings on patent-owner sides (e.g., IPR2024-00173) and the parallel challenges tied to the Feit/Elong district-court fight.

Professional conduct flag. A public USPTO Office of Enrollment and Discipline final order (D2025-21, 2025) resolved stipulated misconduct in his trademark practice: he permitted a paralegal to sign his name to USPTO trademark submissions (including sworn declarations) and share his USPTO.gov account. Practitioners should be aware of this order when evaluating his fitness for USPTO-related work. Bar/credentials: Texas bar (2009, No. 24067927); USPTO Reg. No. 61,554 (registered as agent 2007, as attorney 2009). Education not reliably sourced and omitted.
