Darren's focus is technology – he is interested in deep dives into electronic devices and using that understanding to provide clients with legal advice specific for the technology at issue. Darren's background includes a Master's degree in materials engineering and a Doctorate degree in electrical engineering. He performed research related to materials science and semiconductor manufacturing, and has past experience working as a programmer. With this technical background and over ten years of legal experience, he can interface with engineers, inventors, experts, and other lawyers to counsel regarding intellectual property, transactions, and litigation issues and their impact on the overall business.
Darren's technical expertise includes semiconductor devices, semiconductor packaging techniques, semiconductor fabrication processes, circuit design and simulation, magnetic devices, processor architecture, dynamic random access memory (DRAM) and flash memory design, wireless devices, and computer software. Darren has knowledge and experience with standards-based technologies, including 2G, 3G, 4G, Bluetooth, JDEC standards, ITU standards, and MPEG standards.
In addition to counseling and litigation, Darren assists clients before the U.S.P.T.O. in obtaining patents and around the world to obtain international patent protection. Darren focuses his practice by leveraging his own technical background in electrical engineering to assist clients in interacting with inventors to obtain clearly written and detailed descriptions of inventions. Darren's work has included preparing patent applications in a diverse range of technical fields, but focusing on telecommunications, circuitry, medical devices, and semiconductor devices and manufacturing.
Previously, Darren conducted research in the field of magnetic storage and magnetic devices. His research focused on developing new lithography and etching techniques for massively parallel processing at sizes smaller than 25 nm. These new techniques were used in fabricating and studying bit patterned media, a technology for expanding magnetic recording capabilities. During his research he authored or co-authored over a dozen peer-reviewed journal articles in engineering and science journals and presented at several magnetic materials and nanotechnology conferences.

Representative litigation experience:
Represented a major mobile device chip provider in defending a four-patent investigation brought at the International Trade Commission, where Complainant alleged that three patents covered various aspects of graphical processing units (GPUs) and one patent covered DDR memory controllers. After the claim construction hearing, the case favorably settled.
Represented a major mobile device chip provider in defending a seven-patent investigation brought at the International Trade Commission. The Complainant alleged that the seven patents covered various aspects of graphical processing units (GPUs) contained within accused smartphones. After accelerated discovery and a multi-day evidentiary hearing, the ALJ determined that no violation of section 337 had been established. Over Complainant's objections, the full International Trade Commission declined to review the ALJ's initial determination of no violation. Complainant appealed to the Federal Circuit, but subsequently dismissed the appeal as well as a parallel district court action.
Defended a large manufacturer of LCD displays in a patent litigation suit filed in the Eastern District of Texas; we led the joint defense group during both claim construction and summary judgment and obtained a summary judgment of non-infringement; the case later settled while on appeal.
Represented leading telecommunications provider in defending patent litigation suit in the Eastern District of Texas related to automated messaging.
Represented major technology company in defending patent litigation suit in Eastern District of Texas related to a semiconductor structure found in microprocessors.
