Profile

Samuel Drezdzon is an associate in the Intellectual Property Practice Group in the Dallas-North office of Haynes and Boone.

Sam’s practice focuses on patent litigation and inter partes review (IPR) proceedings before the U.S. Patent and Trademark Office. He has experience with over 30 IPR proceedings defending Fortune 500 companies in disputes involving complex technologies such as cellular standards (3G, LTE, 5G), audio/video codecs (AVC, HEVC, AMR), wireless communications (Wi-Fi, Bluetooth, antenna arrays), internet protocols (IPv6, IP tunneling, VPN), and semiconductor chip fabrication (flash, DRAM, FinFET).

Sam also litigates patent cases before U.S. District Courts and the U.S. International Trade Commission, including asserting and defending infringement claims, managing e-discovery, taking and defending depositions, source code analysis, expert testimony, and all phases of trial. He has litigated patent disputes involving television and smartphone hardware, graphics processing, telecommunications, semiconductors, and medical devices. 

Sam’s practice further includes negotiating licensing agreements for patent portfolios of technology declared standard-essential to cellular and video technology. He also drafts and prosecutes patents directed to the 5G standard in patent offices around the world. He is a member of the Dallas Volunteer Attorney Program, providing pro bono assistance for family law and estate matters.

During law school, Sam served as a judicial intern to the Honorable Chief ALJ Charles E. Bullock at the U.S. International Trade Commission and as a legal intern at the U.S. Federal Communications Commission. Before law school, he received his master’s degree in electrical and computer engineering from Duke University, where he received the John T. Chambers Scholarship for graduate research in photonics. He served as a research assistant studying nano-scale photonic devices, including writing source code for computer simulations, clean-room fabrication of silicon-chip devices, and optical table experimentation. He is a co-author/inventor of journal publications and U.S. patents directed to magnetic optical waveguides.

Presens Precision Sensing, Nos. 2016-2745, 2017-1057 (Nov. 3, 2017) (nonprecedential), the Federal Circuit affirmed the U.S. Patent and Trademark Office Patent Trial and Appeal Board’s inter partes re-examination decision that found U.S. Patent No. 6,673,532 (“the ’532 patent”) invalid as obvious over two prior art references.
