Tulloss Delk — patent litigation profile
Identity note. The tracked name "Tulloss Delk" corresponds to Rodham Tulloss Delk III of IBM Corporation (Armonk, NY), who appears in court and PTAB filings as "R. Tulloss Delk." He should not be confused with the several unrelated attorneys sharing the surname (e.g., the Nevada firm Thorndal, Armstrong, Delk, Balkenbush & Eisinger; McKool Smith's Jason Delk).
Specialty / focus. His publicly verifiable patent work sits in computer, software, and electronics-adjacent technologies. The most concrete data points are (a) gaming-machine and player-tracking technology in IGT v. Alliance Gaming Corp., and (b) computing/security subject matter at IBM — he executed the petitioner's power of attorney for IBM in IPR2020-00323, involving U.S. Patent No. 9,503,473, "Apparatus, System, and Method for Protecting Against Keylogging Malware." Nothing in the public record indicates pharma, life sciences, or mechanical-arts practice. There is no web-searchable practice description from a firm bio (he is in-house), so the technology picture is inferred from these filings rather than stated by the attorney.
Side preference and firm context. The structured data show a single tracked appearance, on the plaintiff side, in the in-house role — consistent with IBM's posture as a large patent owner that both asserts its portfolio and files IPRs. His earlier career was on the defense side: he was a Quinn Emanuel Urquhart Oliver & Hedges associate in the New York/San Francisco offices, where he briefed for defendants-appellees (Alliance Gaming / Bally Gaming) in the Federal Circuit appeal. So the evidence supports "both sides," with the defense work earlier and the owner/enforcement work now under the IBM umbrella. The tracked-case entry itself is untitled in the source data, so I cannot name the specific matter it reflects. He has also been active in the New York Intellectual Property Law Association (in-house corporate practice committee, 2013–14).
Notable matters and PTAB experience. The most prominent verifiable matter is IGT v. Alliance Gaming Corp., No. 2009-1110 (Fed. Cir. Oct. 22, 2009), where he was on the appellees' brief with Charles K. Verhoeven, Amy H. Candido, and Eric Wall; the Federal Circuit affirmed under Fed. Cir. R. 36 (nonprecedential), leaving the district court outcome — including an obviousness summary-judgment ruling and an enablement holding on the '985 patent in the underlying D. Nev. case (No. 2:04-cv-01676) — undisturbed. His PTAB presence is documented at least at the corporate-representation level (the IBM power of attorney in IPR2020-00323), but the public record does not show him as lead or backup counsel arguing IPRs, so I would not describe him as a regular IPR advocate on the available evidence.
Bar / education (partial). Princeton University, A.B. 1996; University of Virginia School of Law, J.D. (Martindale lists 2000; one directory lists 2003 — the year is inconsistent across sources). Admitted in Georgia (2000), California (2003; license now inactive), and New York (2009). USPTO registration status is not confirmed by any source I located.
