Stephanie Sivinski

I'll research this attorney before drafting.

Specialty / focus areas. Stephanie Sivinski is a Dallas-based patent trial lawyer whose practice spans semiconductor manufacturing, pharmaceuticals (including Hatch-Waxman/ANDA), wireless/network technology, thermodynamics, and mechanical arts; she also handles copyright and trade-secret litigation. Her bio cites genetic-science background (B.S., Genetics). Her two tracked appearances both arise from a mechanical/refrigeration patent dispute: ControlTec, LLC v. Anthony, Inc., No. 1:24-cv-00883 (D. Del.), asserting U.S. Patents 7,207,181 and 7,421,847 ("Refrigeration Unit Condensation Prevention," directed to frame and door heating in refrigerated display cases) against Anthony, Inc. and Hill Phoenix, Inc. (Dover Corporation subsidiaries).

Side preference. The tracked data show 2 of 2 appearances on the plaintiff/patent-owner side, both for ControlTec, LLC, and both entered pro hac vice through Haynes and Boone. That is a narrow snapshot rather than a genuine side preference: her published representative matters are weighted toward defense work for operating companies — MediaTek (seven patents, W.D. Tex. No. 6:20-cv-1210, resolved after Markman), a Korean semiconductor-equipment manufacturer and its founder (defense verdict, E.D. Tex.), an oil-and-gas operator sued by an NPE (summary judgment of non-infringement), and a generic drugmaker in an ANDA case (settled). She also appeared for Western Digital Corporation and Western Digital Technologies in a C.D. Cal. patent action (No. 2:24-cv-02864). Net: a genuine two-sided practice, not an NPE/PAE specialist.

Firm context. She is a partner at Haynes and Boone, LLP in Dallas and appears to have spent her patent litigation career there; no prior firm history surfaced in public sources. The tracked matters and the related PTAB filings list her alongside Haynes Boone colleagues Robert P. Ziemian, Ian Rainey, and Charles M. Jones II. No in-house affiliation.

Notable cases / outcomes. Verified per the firm bio and PTAB filings: second-chair defense verdict for a Korean semiconductor-equipment manufacturer and its founder (E.D. Tex.) where plaintiffs sought over $100M and the jury awarded only $622,000 on one contract claim plus $1.36M on the founder's counterclaim (Law360 "Legal Lion," 2019); jury verdict of invalidity for a WAN technology company (E.D. Tex.); a dispositive claim construction for a semiconductor manufacturer affirmed by the Federal Circuit. The most prominent tracked matter is the ControlTec/Antony refrigeration-display-case dispute, which generated parallel IPRs (IPR2025-00559 and IPR2025-00636; institution granted, Director denied discretionary denial) with Anthony as petitioner and ControlTec as owner — Haynes Boone representing ControlTec, though the IPR filings list other Haynes Boone attorneys as of record.

PTAB / IPR experience. Yes, she appears regularly in PTAB work. Public PTAB records show her as Haynes Boone counsel for petitioner Apple in the Apple v. Corephotonics camera-lens IPRs (IPR2020-00487 line), where she took and defended expert depositions, and she is listed as PTAB counsel on other petitions; she has also published and spoken on Federal Circuit appeals from the PTAB and on trial strategy when IPR is unavailable. Unresolved item: I could not locate a public docket for a proceeding captioned Anthony, Inc. v. ControlTec, LLC; it appears to be a related action or appeal in the same dispute rather than an independent matter.

Bar / education. Admitted in Texas (2010) and registered with the USPTO (2018); also admitted to the U.S. Supreme Court, Federal Circuit, and the E.D./N.D./S.D./W.D. Tex. J.D., University of Texas School of Law (2010, high honors, Order of the Coif); B.S., Genetics, Texas A&M University (2007); law clerk to Judge Mark E. Fuller, M.D. Ala. (2010–2011).
