Samuel W. Riebe

I'll research this attorney's professional background and patent litigation practice.

Let me verify the firm affiliations and dig into the tracked cases and PTAB work.

Samuel W. Riebe — Winston Taylor LLP (Dallas) | Patent Litigation

Specialty / focus. Riebe is an intellectual property litigator working mainly on complex, technology-heavy patent disputes. His tracked matters are the SAP–Valtrus litigation, where the asserted patents cover enterprise computing subject matter — database and middleware messaging architecture, networking/network-security messaging, and multiprocessor/cache-memory design. That fits an engineering profile: he holds a B.S. in mechanical engineering and, before and during his legal career, worked as a field engineer and later prosecuted domestic and international applications in oil and gas, semiconductors, biomedical devices, power generation and storage, electronics, and computer software, per his firm bio. Search results show no Wi-Fi/SEP standards or Hatch-Waxman pharma practice.

Side preference. He works both sides, though the tracked data tilts defense-of-operating-company: 1 defendant-side and 1 plaintiff-side appearance, and the two are the same dispute — Valtrus's NPE infringement suit against SAP in E.D. Tex. (where he appeared for SAP as counsel) and SAP's parallel Delaware declaratory-judgment action (back-up counsel). His reported matter list confirms the split: he defended U.S. Well Services against Halliburton in a hydraulic-fracturing case (resolved by settlement), appeared for Qualcomm in Xueshan Technologies v. Qualcomm (W.D. Tex. 2025), and represented patent owner/app developer Flypsi (Flyp) against Google.

Firm context. He is currently at Winston Taylor LLP's Dallas office; the firm's Texas practice was renamed from Winston & Strawn LLP to Winston Taylor LLP effective June 1, 2026, with the same Dallas address, so his tracked Winston & Strawn appearances are continuous with his present firm. Before private practice he was a law clerk to the Honorable Roy S. Payne of the Eastern District of Texas, managing a share of that patent docket and supporting dozens of Markman hearings and trials, and he earlier prosecuted patents at a boutique IP firm. Note: a King & Spalding bio PDF under the same name and credentials also appears in search results; I could not verify whether that reflects a prior, current, or unrelated affiliation, so I treat it as unconfirmed.

Notable matters, PTAB, bar/education. His most prominent reported result is the firm-reported $12 million jury verdict for Flypsi (Flyp) against Google in W.D. Tex. over mobile-device technology; a favorable U.S. Well Services settlement is also reported (both are firm descriptions, not independently verified in my searches). In the SAP–Valtrus dispute he is a named PTAB back-up counsel on multiple SAP petitions (e.g., IPR2025-00416/-00418/-00420) and appears as lead attorney on at least one related petition, so he has repeat IPR experience. Education/admissions: J.D., Case Western Reserve University (2020); B.S., mechanical engineering, Colorado State University (2014); admitted in Texas and Utah and registered with the USPTO (Reg. No. 78,044).
