Sorey & Gilliland

Sorey & Gilliland is a Texas-based law firm with its headquarters in Longview, Texas, and additional offices in Waco. The firm has been recognized by U.S. News & World Report and The Best Lawyers in America as among the "Best Law Firms" for its work on behalf of plaintiffs in personal injury cases in the Tyler metro area. While a specific AmLaw or Chambers ranking for their patent litigation practice or overall firm size (number of attorneys) is not publicly available, the firm describes itself as offering "Big Firm Experience. Small Firm Attention."

The firm's intellectual property litigation practice, overseen by Daniel L. G. Gilliland, primarily focuses on representing plaintiffs in patent infringement disputes. Their tracked cases indicate an involvement in technology areas such as web conferencing and software, as seen in Intent IQ, LLC v. Google LLC, which involved web conferencing systems with time-shifting capabilities. Another tracked case, Orthosie Systems, LLC v. IMETRIK, Inc., further highlights their plaintiff-side patent litigation work, though specific technology details for this case were not widely disclosed in the search results.

Sorey & Gilliland exclusively represents plaintiffs in its tracked patent litigation matters, serving as lead counsel in Intent IQ, LLC v. Google LLC and local counsel in Orthosie Systems, LLC v. IMETRIK, Inc. This aligns with the firm's broader focus on plaintiff-side litigation, including personal injury and commercial disputes.

A notable case outcome for the firm's IP practice involves Intent IQ, LLC v. Google LLC. In this matter, the U.S. Court of Appeals for the Federal Circuit affirmed the district court's dismissal of the patent infringement complaint, holding that the asserted patent claims were directed to patent-ineligible subject matter under 35 U.S.C. § 101. Prior to co-founding Sorey & Gilliland, key partner Daniel L. G. Gilliland achieved a significant $115 million biotech patent infringement verdict in Washington state in 2013, one of the largest patent infringement verdicts in the state's history at the time. Details regarding a public outcome for Orthosie Systems, LLC v. IMETRIK, Inc. were not readily available in public records.

Information regarding Sorey & Gilliland's specific practice volume or notable engagements before the Patent Trial and Appeal Board (PTAB) for Inter Partes Reviews (IPR) or Post-Grant Reviews (PGR) was not prominently detailed in the publicly available search results.

Key partners in the firm's patent litigation practice include Daniel L. G. Gilliland, who oversees the intellectual property litigation practice and is recognized as a veteran patent trial lawyer.
