Nadia Haghighatian

I'll research this attorney's background before drafting.

Let me dig into specific cases and outcomes.

Professional Summary — Nadia E. Haghighatian (Winstead PC, Austin)

Specialty / focus. Haghighatian is a patent litigator whose practice, per her Winstead bio, spans software, telecommunications, wireless/data-encoding systems, electrical and mechanical technologies, and semiconductors — grounded in an undergraduate electrical engineering background. Her representative matters she describes include cybersecurity/anti-malware software, video streaming and CDN technologies, mobile device and authentication patents, audio/video codec and graphics processing patents, and semiconductor fabrication (including physical vapor deposition). She also handles patent and trade-secret disputes in the oil and gas sector and maintains a trademark practice (district court and TTAB). No pharma/life-sciences work appears in either the tracked list or her published practice description.

Side preference. The tracked docket is small (two appearances, both plaintiff-side, at Winstead) and both records are unnamed, so the structured data alone would misleadingly suggest a plaintiff-only practice. Her broader, verifiable record is genuinely mixed: the largest publicly documented patent campaign she worked on — Webroot, Inc. / Open Text Inc. v. AO Kaspersky Lab (W.D. Tex., Waco Div., No. 6:22-cv-00243) — was plaintiff-side, while her firm bio describes substantial defense work for operating companies (a global semiconductor equipment maker and chip manufacturer, an international oilfield services company, a major airline, and consumer electronics companies). She is best characterized as a two-sided IP litigator rather than an NPE/PAE-specialist, though her tracked appearances currently skew plaintiff.

Firm context. Shareholder in Winstead's Business Litigation / IP Litigation group, which she joined in July 2024 in the Austin office. She began her career at Thompson & Knight in 2013 and remained there until 2022, then moved to Holland & Knight (following the Thompson & Knight combination), and subsequently to Kirkland & Ellis, where she was a partner immediately before joining Winstead. Court filings confirm the progression: she appeared under tklaw.com, hklaw.com, and kirkland.com addresses before the current Winstead affiliation. Some third-party aggregator profiles list these dates inconsistently; the firm announcement and Texas Lawbook reporting are the reliable sources.

Notable matters / outcomes. The most prominent documented matter is the Webroot/Open Text cybersecurity campaign, in which she served on plaintiffs' side at Kirkland against Kaspersky, CrowdStrike, Forcepoint, Sophos, and Trend Micro across consolidated W.D. Tex. cases and parallel IPRs; those disputes resolved through stipulations of dismissal and settlement, with the Kaspersky IPR terminated by joint motion in April 2024. On the trademark side, she asserted claims for plaintiff eCU Technology LLC against CU Direct Corp. (N.D. Tex.) and for The Container Store against Clever Container Co. Her bio credits her with being part of the trial team that obtained a take-nothing judgment against what the firm characterizes as the largest patent damages claim in U.S. history — I could not independently verify the case name, so that claim should be treated as firm-reported.

PTAB / IPR experience. She appears in IPR proceedings, principally on the patent-owner side (e.g., the Open Text/Webroot defensive IPRs arising from the cybersecurity litigation). No USPTO registration number for her was found in the sources reviewed, so it is not established that she is a registered patent practitioner.

Bar / education. Admitted in Texas since 2013 (SBN 24087652); J.D., Texas Tech University School of Law (2013); B.S., electrical engineering, University of Texas at Austin. Repeatedly named a Texas Super Lawyers Rising Star in IP litigation (2018–2023, 2025, 2026).

Note: No disambiguation issue arose — only one attorney practicing under this name appears in the relevant Texas IP litigation sources. Contact details and personal information found in data-broker listings were disregarded.
