7 tracked appearances — 2 plaintiff · 5 defendant.
Specialty & background
I'll research this attorney before drafting. Let me run several searches.
Let me dig deeper into her specific case roles and firm bio.
Professional Summary — Gabrielle L. Kiefer (Merchant & Gould P.C.)
Specialty / focus. Kiefer is an IP litigation and technology-law associate in Merchant & Gould's Minneapolis office. Her published practice description (University of Minnesota Law School adjunct profile; firm-related listings) emphasizes IP litigation, brand protection, and transactional/licensing work for consumer products and services companies, medical devices, and related industries. Her tracked patent litigation is concentrated in mechanical/electromechanical consumer products — chiefly the multi-patent dispute over dual-fuel portable generators between Champion Power Equipment and Generac Power Systems, which one E.D. Wis. opinion described as "mechanical systems rather than abstract subjects like software or drug delivery mechanisms." She has also appeared for plaintiff-side parties in a boat-lift patent case (Golden v. Neptune Boat Lifts, S.D. Fla. 2021) and for Fair Isaac Corporation in D. Minn. (2022). I did not find published descriptions tying her to Wi-Fi/standard-essential-patent, pharma, or life-sciences litigation.
Side preference. Her tracked record skews defense: 5 defendant-side versus 2 plaintiff-side appearances. Four of the seven tracked entries are variations of Champion Power Equipment Inc. v. Generac Power Systems Inc., where she represents the defendant, Generac — a Justia docket entry confirms her appearance for Generac in E.D. Wis. No. 2:24-cv-01281 (filed alongside Thomas J. Leach in December 2024). The plaintiff-side work is for operating companies (Fair Isaac; the Neptune boat-lift plaintiffs), not for NPEs/PAEs. On this record there is no evidence of a plaintiff/NPE monetization practice; the pattern is defense of operating companies with occasional plaintiff-side representation.
Firm context. All tracked appearances are at Merchant & Gould P.C., a national IP boutique headquartered in Minneapolis. I found no verified prior-firm history for her patent litigation work; she appears to have practiced at Merchant & Gould since being licensed (2021). She also serves as an adjunct instructor for the Intellectual Property Moot Court at the University of Minnesota Law School.
Notable cases / outcomes. The principal matter is the Champion–Generac generator campaign: parallel district court actions (E.D. Wis.) and a large set of related IPRs, with co-pending cases against Firman Power Equipment, Harbor Freight Tools, and Midwest Equipment Sales, and with inequitable-conduct and prosecution-bar issues litigated. The IPRs drew sua sponte Director Review (per a March 2026 Jones Day PTAB blog report) and, separately, the district court declined to exempt Champion's outside prosecution counsel from a patent prosecution bar — all context on the same dispute, though those rulings concern other counsel, not Kiefer. No verdict, settlement, or Federal Circuit outcome attributable to her personally was verifiable in the sources reviewed.
PTAB / IPR experience. I found no IPR or PGR proceeding in which Kiefer is listed as counsel of record. In the Champion–Generac/Firman/Harbor Freight IPRs, the PTAB filings name specialized firms (e.g., Perilla Knox & Hildebrandt; Ziolkowski Patent Solutions Group) rather than her. On the available record, she should not be characterized as a regular PTAB practitioner.
Bar / education. J.D., University of Wisconsin Law School (2020); B.S.E., Case Western Reserve University. Admitted in Minnesota (Bar No. 0402364) and Wisconsin (2021), and registered with the USPTO (Reg. No. 79271). (Bar admissions per Avvo and court filings; confirm current status against the state bars and USPTO roster.)
Sourcing note: the seven tracked appearances are largely duplicative of the same Champion–Generac caption from different records, and two entries are untitled in the underlying data, so the counts above are the best available read rather than a fully de-duplicated docket history. Details on her firm's or PatentBots' aggregate prosecution data were not attributed to her practice, as that data appears to be customer-number level rather than individual.
