Marshall J. Gillam

I'll research this attorney before drafting.

Attorney Summary: Marshall J. Gillam

Identity verification note. I was unable to verify a licensed attorney named "Marshall J. Gillam" in any public source (firm websites, court dockets, Law360, Justia, State Bar listings, PTAB filings). The tracked record attributes the single appearance to "Gillam & Smith," a small Marshall, Texas IP boutique whose name partner is Harry Lee "Gil" Gillam, Jr. No attorney by the name "Marshall J. Gillam" appears on that firm's roster or in its public filings. The entry may be a data artifact (e.g., a conflation of the firm's Marshall, Texas location with the Gillam surname). Everything below is therefore sourced at the firm level and should not be attributed to this individual without confirmation.

Firm context and specialty. Gillam & Smith LLP maintains offices in Marshall and Tyler, Texas (303 S. Washington Ave., Marshall; 102 N. College Ave., Suite 800, Tyler). The firm was established as a partnership in 2004 by Gil Gillam and Melissa Richards Smith, who have practiced together since 1997. It is best known as a patent litigation shop concentrated in the Eastern District of Texas — Marshall Division, handling local-counsel and trial roles across electronics, semiconductor/display, software, and consumer-device patent disputes. Reported technology coverage in the firm's docket is broad and electronics-heavy rather than pharma or life sciences.

Side preference. The tracked data show one appearance, on the plaintiff side, as trial counsel. That single data point is too thin to establish a practice pattern, and it sits in tension with the firm's public profile: Gillam & Smith is widely described as a defense-side and local-counsel firm in EDTX patent cases, with substantial work for operating companies. Secondary reporting (Asian Economy, June 2024) identified the firm as the second most frequently appointed firm by Samsung Electronics and LG Electronics in their U.S. patent litigation, with roughly 95 combined appointments. Firm materials also state that the attorneys represent both plaintiffs and defendants in IP and commercial matters, so the record supports a two-sided practice rather than a dedicated NPE/PAE prosecution model.

Notable matters, PTAB, and credentials. The firm's most prominent publicly reported patent result is its long-running role for Apple in the Optis Wireless Technology litigation before Chief Judge Rodney Gilstrap in Marshall, where the defense prevailed at a third trial following two earlier nine-figure plaintiff verdicts; Melissa Smith of Gillam & Smith was named an Am Law "Litigator of the Week" for that outcome. Gil Gillam obtained a $55 million verdict in MaximiCER v. Pepsi (2003), reported as the largest of its kind in Marshall federal court at the time. Firm attorneys appear in PTAB proceedings (e.g., CBM2016-00055, IPR2023-01268), though those appearances are attributed to Smith and Gillam, not to the name in the tracked record. Bar admissions and education for the individual "Marshall J. Gillam" are not reliably sourced and are omitted; the tracked case itself is unnamed in the underlying data.
