Daniel S. Shuminer

I'll research this attorney's background and practice.

Daniel S. Shuminer — Patent Litigation Practice Summary

Focus areas. Shuminer's practice centers on electronics- and software-adjacent patent litigation rather than the life sciences. His Winstead bio lists medical devices, cybersecurity, computer networking, wireless communications, LEDs, photovoltaics, and semiconductors; his earlier Norton Rose Fulbright bio lists computer networking, semiconductors, photovoltaics, medical devices, and autonomous vehicles. His listed matter work includes firewall technology, microcontroller/semiconductor patents, and flare-gas resource management (mechanical/upstream energy), and his technical background is a BS in materials science and engineering. I found no indication of pharmaceutical, biologics, or standards-essential Wi-Fi/FRAND work.

Side preference and firm context. Both tracked appearances are plaintiff-side, at Winstead PC (Austin), where he is listed as Associate on one matter and Attorney on the other. The verified assertion work is patent-owner/monetization-side: he is counsel for MOSAID Technologies Inc., a wholly owned subsidiary of the WiLAN/Quarterhill patent licensing group, i.e., an NPE/PAE plaintiff. That said, his firm bios describe defense work (representing a large cybersecurity company in a firewall case in the E.D. Va.), and a docket search shows a defense-side appearance for Zhuhai CosMX Battery in Ningde Amperex Technology Ltd. v. Zhuhai CosMX Battery Co. (E.D. Tex. 2:22-cv-00232, appeared Nov. 2022) during his Norton Rose Fulbright tenure (listed there as an associate). Before Winstead he was a patent litigation associate at Norton Rose Fulbright and earlier an associate at Sheridan Ross; court records also list him as a law clerk to Magistrate Judge Roy S. Payne in the E.D. Tex. Marshall Division (2020–2022). One business-data aggregator (RocketReach) lists a current in-house "Patent Counsel" role at WiLAN starting in 2026; I could not independently verify that move, and the tracked data still reflects Winstead.

Notable matters and PTAB experience. The most prominent tracked matter is MOSAID Technologies Inc. v. Infineon Technologies AG (W.D. Tex. Nos. 1:25-cv-00358 and 1:25-cv-00436), where he appears on MOSAID's infringement contentions asserting U.S. Patent Nos. 7,111,179, 7,051,306, and 7,349,448 against Infineon's PSoC, TRAVEO, and XMC microcontroller product families. Infineon filed petitions for inter partes review (IPR2025-01487 and IPR2025-01489, Aug. 2025) and stipulated to forgo duplicative district-court §102/§103 grounds if instituted — so his IPR exposure here is as patent owner's counsel responding to petitions, not as petitioner. His Norton Rose Fulbright bio states that post-grant practice before the PTAB is a focus, and his name appears as counsel of record on PTAB filings, but I did not verify a substantial body of personally argued IPR/PGR proceedings. I found no reported verdicts, damages awards, or Federal Circuit decisions attributable to him personally.

Bar and education. Admitted in Texas (2021) and Colorado (2019); JD, Emory University School of Law (2019, TI:GER intellectual property certificate); BS, Materials Science and Engineering, University of Florida (2015).

Note on sourcing: the tracked case list contains two Winstead plaintiff-side appearances without case names, so the specific matters above were matched from public court and PTAB records. The reported WiLAN in-house move is from a business-data aggregator only and is flagged as unverified.
