Mark R. Bagley

Specialty / focus areas. Mark R. Bagley is a Chicago-based litigator whose patent work sits within a broader IP practice spanning patent, trademark, copyright, and unfair-competition litigation. His tracked patent matter involved software/e-commerce technology: in Linfo IP, LLC v. The Gap, Inc. (E.D. Tex. 6:23-cv-00635), he defended against infringement claims over U.S. Patent No. 9,092,428, directed to text-content discovery in digital retail interfaces. His firm bio also cites patent work for an Italian manufacturer of performance automotive tools and design-patent defense for an internet retailer against a fashion eyewear maker, suggesting a mix of mechanical and design-patent matters rather than a concentration in Wi-Fi standards, pharma, or other single technology silos.

Side preference. Based on the tracked case list (one appearance, all defendant-side), Bagley appears to practice primarily on the defense side, representing operating companies against NPE/PAE plaintiffs. In Linfo IP, he defended retailer The Gap against a patent assertion entity (plaintiff's counsel William Ramey). His broader portfolio also includes trademark and copyright defense for national and international operating companies, consistent with a defendant-oriented practice.

Firm context. Bagley is of counsel at Tolpin Law (Tolpin & Partners PC) in Chicago, where he appears to have practiced since at least 2018 (court filings list Tolpin & Partners). No prior-firm history beyond Tolpin was verifiable in public sources.

Notable cases or outcomes. The most prominent tracked case is Linfo IP, LLC v. The Gap, Inc., which ended in a procedural win for the defense: the parties jointly moved under 28 U.S.C. § 1404(a), and the E.D. Tex. court transferred the case to the Southern District of Texas, Houston Division, without a merits ruling on infringement or validity. Per his firm profile, Bagley has also obtained a successful jury-trial verdict in a trademark infringement case for a tax preparation firm and has litigated patent, copyright, and trade-secret matters through trial. No Federal Circuit appeals or reported verdicts in patent cases were independently verified.

PTAB / IPR experience. No evidence of regular IPR/PGR practice was found. His USPTO administrative experience is in trademark opposition/cancellation proceedings (TTAB-type work), not patent post-grant review.

Bar / education. Admitted Missouri (1999) and Illinois (2000); U.S. District Courts for N.D. and C.D. Illinois and E.D. Missouri; Seventh Circuit and Federal Circuit (per firm bio). Harvard A.B. (1996, cum laude) and University of Chicago J.D. (1999, Law Review).
