Eric Hansen

I'll research this attorney before drafting.

Let me verify the tracked case and check for PTAB work.

Let me verify the 5G FRAND verdict and the Nokia v. HP lead counsel role.

Eric S. Hansen — McKool Smith (Dallas) | Patent Litigation

Focus areas. Hansen's practice is concentrated in electronics, telecommunications, and standards-driven patent litigation — 4G/LTE/5G cellular SEPs, 802.11 Wi-Fi, H.264/H.265 video coding, semiconductor manufacturing, flash memory, and software — with secondary work in mechanical and chemical arts (downhole oilfield tools, composite parts). He handles matters from pre-suit diligence through discovery, claim construction, trial, and appeal, and also appears before the ITC in Section 337 investigations. The Nokia v. HP, Inc. et al. matter in the tracked list fits this profile: Nokia's video-coding (H.264/H.265) patent assertions against HP in the District of Delaware and a parallel ITC complaint against laptop, tablet, and television respondents.

Side preference. The tracked dataset shows 2 plaintiff-side appearances and 0 defendant-side, with Hansen listed as lead counsel in Nokia v. HP and local counsel in an unidentified second matter — but that sample is thin and likely skewed. His documented trial record is predominantly defense-side, and his firm bio states he represents companies "as both plaintiffs and defendants." Notably, he has acted for both SEP owners and implementers: he was part of the McKool Smith team that defended AT&T, Verizon, T-Mobile, Ericsson, and Nokia in the ASUS/Celerity IP 4G/5G SEP case, while also representing Nokia as patent owner in video-coding IPRs and representing NPE-side clients such as MOSAID, Negotiated Data Solutions, and Solid State Storage Solutions.

Firm context and notable matters. Hansen has been at McKool Smith since before 2014 (first tracked appearance there in the ContentGuard Holdings matters) and was promoted to Principal effective January 1, 2022; his earlier roles at the firm included director. Before McKool Smith he clerked for Magistrate Judge Chad Everingham in the Eastern District of Texas. His most prominent recent results: the August 26, 2026 consolidated EDTX defense verdict in ASUS Technology Licensing Inc. v. AT&T Inc., No. 2:23-cv-00486 (E.D. Tex.), where the jury found no infringement of all nine asserted claims, invalidated all three patents, rejected the plaintiffs' $436 million damages demand, and found the plaintiffs had breached their own FRAND obligations; and the July 11, 2025 verdict in Daingean Technologies Ltd. v. T-Mobile, No. 2:23-cv-00347 (E.D. Tex.), where the jury found no infringement via Nokia base stations and awarded only $2 million against Ericsson base stations versus the $245 million sought. He was also named in the Patexia ITC Intelligence Report rankings (2023–2026) among the most active and highest-performing attorneys representing complainants.

PTAB / IPR experience. Hansen is a registered patent practitioner (Reg. No. 63,095) and does appear in PTAB proceedings, including as backup counsel for patent owner Nokia Technologies Oy in the video-coding IPRs (e.g., IPR2021-00038) and on Ericsson-side IPR work against Sol IP (IPR2020-00239). Available sources do not show him as lead counsel in a large volume of IPR filings, so his PTAB practice appears to be regular but secondary to his district court and ITC work.

Bar and education. Admitted in Texas (2008) and before the USPTO; J.D., Northwestern University Law School (2007); M.S., Electrical Engineering, University of Texas at Dallas (2010); B.S., Materials Science and Engineering and B.S., Mathematics, MIT (2003).

Note: the second tracked appearance is listed only as "Untitled case" (McKool Smith, plaintiff side, local counsel), so no details can be attributed to it. Firm bio and press releases are the primary sources here; the Delaware docket entries confirm McKool Smith's representation of Nokia Technologies Oy in the HP matter.
