Jonathan Auerbach — Patent Litigation Practice Summary

Specialty / focus. Jonathan Auerbach is an IP litigator whose practice centers on patent litigation in federal district courts, the International Trade Commission (ITC), and the PTAB. His technology exposure is concentrated in LED/lighting systems (including the tracked matter, Jesco Lighting Group v. AGS Lighting Management, LLC, which concerns linear LED lighting apparatus patents and is tied to a related Delaware action and IPR2025-01328), with additional experience in pharmaceuticals (Hatch-Waxman/ANDA work) and financial services, per his firm biography.

Side preference. Auerbach works both sides. His one tracked appearance is plaintiff-side in the Jesco/AGS dispute (Radulescu LLP represents Jesco), but his broader docket is mixed: he has represented patent owners/plaintiffs (Cephalon, OSRAM, Bridgelux, Merck, Lambeth Magnetic Structures) and defendants/respondents (WAC Lighting, MaxLite, Teva). No clear operating-company-versus-NPE orientation is evident.

Firm context & notable matters. He is Of Counsel at Radulescu LLP (New York), a boutique patent litigation firm, and was previously an associate at Goodwin Procter LLP (2008–2016), where he worked on the In re Bendamustine Consolidated Cases (D. Del.), in which Cephalon's TREANDA® patents were found valid and infringed after a two-week bench trial. Other notable matters include the OSRAM v. LG ITC investigation (complainant-side, initial determination of violation against LG), the Philips v. WAC Lighting district court and ITC cases (defense-side), and defense of Bridgelux in four Everlight IPRs.

PTAB/IPR experience. Auerbach appears regularly before the PTAB on both sides — for patent owners (Everlight v. Bridgelux, IPRs 2018-1482–1485; Minka Lighting v. Wangs Alliance, IPR2024-01027; Lite-On v. Sensor Electronic Technology, IPR2022-00780) and as petitioner-side counsel (Jesco v. AGS Lighting, IPR2025-01328).

Bar / education. J.D., George Washington University Law School (2008, George Washington Law Review); B.S. Biological Engineering, Cornell (2005); New York bar (2009); admitted S.D.N.Y., E.D.N.Y., Court of Federal Claims, Second Circuit; registered before the USPTO (Reg. No. 59,193). Note: Jonathan N. Auerbach, a partner at Stikeman Elliott in Montréal, is a different individual with a separate Canadian IP practice.
