Babak Tehranchi

I'll research this attorney's professional background before drafting.

Let me verify the specific tracked cases and outcomes.

Babak Tehranchi, Ph.D. — Perkins Coie (San Diego, CA)

Babak Tehranchi is a Perkins Coie partner whose practice sits at the intersection of patent prosecution, PTAB post-grant work, and patent litigation support. His technical focus, per the firm's own practice description, runs to semiconductor devices, wireless communications, cloud systems, optics/photonics, AI and software, electronics, and medical devices — a range consistent with the tracked docket, which spans OLED display technology (BOE/Samsung Display), LTE/5G standard-essential and implementation patents (OnePlus/Pantech), enterprise cybersecurity (Netskope/Fortinet), printing and wireless-printing patents (Lexmark/Flexiworld), and oil-and-gas fluid-handling control systems (TankLogix/SitePro). His background is unusually deep on the technical side: he holds a Ph.D. in Optical Sciences and an M.S. in Electrical Engineering (University of Arizona) and worked as a research scientist/engineer at Eastman Kodak R&D and Verance Corporation before practicing law, and he is listed as an inventor on 49 U.S. and international patents.

On side preference, the structured list shows four plaintiff-side and two defendant-side appearances, but the practical pattern is that he represents technology operating companies rather than NPEs/PAEs. He has been the petitioner's lead counsel for OnePlus in a multi-patent IPR campaign against Pantech's wireless patents, lead counsel for BOE in its PTAB challenges to Samsung Display's OLED patents, and counsel for Netskope in its affirmative case against Fortinet. On the defense side he has appeared for Lexmark against Flexiworld and for SitePro as patent owner/defendant in the TankLogix dispute — i.e., he works both sides of the "v.," but the clients are product companies (display makers, handset makers, security software, printers, industrial equipment), not assertion entities.

Firm context. He is at Perkins Coie, where he serves as co-chair of the firmwide Post-Grant Practice. Earlier in his career he was an attorney, patent agent, and law clerk at Foley & Lardner in San Diego, preceded by in-house/industry roles as a senior staff engineer and patent agent at Verance and a senior research scientist at Eastman Kodak.

Notable matters and PTAB experience. Post-grant work is his signature: his firm bio states he has participated in more than 125 IPRs, PGRs, and CBM reviews since 2012 for clients including BOE Technology Group, Netflix, Hulu, Microsoft, Tyco, Lexmark, HTC, Netskope, and Peloton, on both petitioner and patent-owner sides, and he was recognized in Patexia's 2021 IPR Intelligence Report for patent-owner-side performance. In the tracked matters he is docketed as IPR lead counsel for OnePlus against Pantech and for BOE against Samsung Display, and as patent-owner-side counsel for SitePro in the TankLogix IPR/PGR family (including a related § 325(d) discretionary denial). On outcomes: the underlying BOE–Samsung Display OLED dispute (ITC Section 337 plus parallel E.D. Tex. actions) settled in November 2025 with all suits and ITC investigations withdrawn; a March 2025 ITC final determination had found BOE infringed three Samsung Display patents but declined an exclusion order on domestic-industry grounds. Note that the OnePlus/Pantech IPRs run parallel to a separate E.D. Tex. jury trial in which Pantech obtained roughly $10.26M in damages ($7.41M on SEPs plus $2.85M on non-essential patents); I could not verify from available sources whether Tehranchi's team handled the district-court defense, only his role as IPR lead counsel for OnePlus/Pantech Wireless.

Bar and education. Admitted to the State Bar of California (December 2009); registered with the USPTO (Reg. No. 55,937). J.D., University of San Diego School of Law; Ph.D. and M.S. in Optical Sciences and M.S./B.S. in Electrical Engineering, University of Arizona.

Sourcing note: the technical focus, post-grant volume, and education details come from his firm biography; case roles and outcomes come from PTAB filings/dockets, court records, and contemporaneous press coverage of the BOE–Samsung Display settlement. Details of confidential settlements and any district-court roles beyond the tracked docket were not independently verifiable.
