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

Let me dig deeper on case outcomes and credentials.

Let me verify a few remaining details on recent matters and IPR activity.

Professional Summary — Jonathan K. Waldrop

Specialty / focus. Waldrop is a patent litigator whose docket centers on software, internet and communications technologies rather than life sciences or mechanical arts: interactive web technologies, video streaming and video-on-demand, cable/telecom, mobile wallets and digital payments, and computer-assisted sales processes. Firm and ranking profiles (Kasowitz, Legal 500, IAM Patent 1000, BTI) describe him as chairing Kasowitz's IP group with additional experience in medical devices, gaming systems, cooking ovens, and complex financial-transaction technologies, plus some commercial and antitrust work. His tracked caseload matches that profile — in-flight connectivity and airline systems (Intellectual Ventures' 2024–25 campaigns against American Airlines, Southwest and others), mobile-wallet patents (Fintiv/Apple), browser interactivity (Eolas/Google), and semiconductor/streaming assertions (Greenthread, AlmondNet, Radiant Patents).

Side preference — both sides, with a tilt toward patent owners. The tracked data show 29 plaintiff-side versus 14 defendant-side appearances, but those plaintiff entries are dominated by repeat patent-owner clients (Intellectual Ventures, Fintiv, AlmondNet, Greenthread) rather than a broad NPE book of business. His most-cited defense work is for operating companies — Google/YouTube against Eolas, Roku in MV3 Partners v. Roku, and IV's adversaries in declaratory-judgment actions (Viasat, Munich Re, Home Depot). In practice he is a both-sides trial lawyer with a substantial affirmative-assertion practice.

Firm context. He is a partner at Kasowitz Benson Torres LLP, head of its Intellectual Property group, and managing partner of the firm's Silicon Valley/San Francisco office (Redwood Shores). He came to Kasowitz in 2012 as part of a six-lawyer IP team from Sutherland Asbill & Brennan (he had joined Sutherland in 2009 as an associate in Atlanta); earlier stops include Greenberg Traurig, Kilpatrick Stockton and Fried Frank. The tracked one-off appearances at Susman Godfrey and Caldwell Cassady & Curry appear to be isolated co-counsel roles, not prior employers of record.

Notable matters and outcomes.

• Fintiv, Inc. v. Apple Inc. — Represented patent owner Fintiv. Won a May 2020 PTAB discretionary denial of Apple's IPR petition based on the advanced stage of the parallel district court case, the first such denial; the underlying order became the precedential "Fintiv Rule" and was named a top patent ruling of 2020 by Law360. On May 16, 2025, the Federal Circuit reversed summary judgment of non-infringement for Apple and remanded for trial on the '125 patent.
• Eolas Technologies v. Google/YouTube (E.D. Tex.) — Jury verdict of invalidity defeating claims for hundreds of millions in damages; affirmed by the Federal Circuit in July 2013. The related Eolas II dispute produced a rare Federal Circuit writ of mandamus transferring the case to the Northern District of California.
• Intellectual Ventures v. Tesla and the 2024–25 IV airline/aviation campaign (American Airlines, Southwest, Viasat) — lead or lead-trial counsel for IV in parallel district court and PTAB proceedings.
• MV3 Partners v. Roku (W.D. Tex.) — Tried to a defense verdict for Roku; a loss on the plaintiff side, though he has publicly described it as one of the first pandemic-era patent jury trials.
• Firm profiles also credit him with defeating five writs of mandamus seeking transfer of patent cases out of the Western District of Texas (2022).

PTAB / IPR experience. He appears regularly in PTAB proceedings, both as patent-owner counsel (Fintiv IPRs; IV as patent owner in Tesla v. Intellectual Ventures II, IPR2025-00343, and American Airlines v. Intellectual Ventures II, IPR2025-00782) and in related district-court/PTAB coordination. His PTAB filings list him as a registered practitioner, USPTO Registration No. 50,334.

Bar / education. J.D., University of Virginia School of Law, 2000; B.S. with honors in mechanical engineering and materials science, Harvard University, 1997. Licensed in California (admitted 2000–01); registered to practice before the USPTO. I did not verify Georgia or other state admissions from a primary source, so those are omitted.
