Kunzler Bean & Adamson

I'll verify the firm's profile and practice details before drafting.

Let me dig into the specific cases and the firm's IP practice pages.

Kunzler Bean & Adamson, PC — Patent Litigation Practice Summary

Firm overview. Kunzler Bean & Adamson, PC ("KB&A"), founded in 2000, is a Salt Lake City–headquartered boutique with its principal office at 50 West Broadway, Suite 1000. A June 2021 firm press release announcing the addition of litigation partners Chad Pehrson and Paul Sampson also references a La Jolla, California office, though the US News law-firm directory currently lists only one U.S. location — so the current scope of the California footprint is not reliably confirmed. Third-party business databases (PitchBook, Salary.com) put the firm at roughly 50–60 total employees and describe it as a boutique; no AmLaw or Chambers ranking for the firm was located, and I found no verifiable revenue or attorney-count figures from a primary source. The firm self-describes as a "boutique law firm with world-class capabilities in litigation, intellectual property, and venture capital transactions," and US News lists corporate, IP, labor and employment, and litigation as its practice areas. Treat it as a regional IP-and-corporate boutique, not BigLaw.

IP litigation specialty. The firm's IP work skews toward electrical, computer, and software technologies rather than pharma or life sciences. Its prosecution client base, visible in USPTO practitioner data, is heavy on computer hardware and software — Lenovo entities (by far the largest volume), SambaNova Systems, LONGITUDE FLASH MEMORY SOLUTIONS, MONTEREY RESEARCH, Proofpoint, and The Boeing Company, plus Glycom A/S in the chemistry space. On the litigation side, the most visible public matter is the Modern Font Applications LLC campaign asserting U.S. Patent No. 9,886,421 ("Allowing operating system access to non-standard fonts in a network document") — a software/font-rendering patent asserted against restaurant and retail mobile apps, including Modern Font Applications LLC v. PetSmart, Inc. and v. Domino's Pizza (D. Utah), with KB&A attorneys signing the complaints. The '421 patent traces to a 2001 priority application filed by an "Adamson," per the complaint's own recitation, though I have not verified that this is a firm-affiliated individual.

Side preference. The tracked dataset is thin and points one direction: a single appearance, on the plaintiff side, with Chad S. Pehrson as counsel. Public records show the same plaintiff-side orientation in the Modern Font Applications matters, where KB&A served as counsel to a Utah patent assertion entity — an NPE/PAE enforcement posture rather than operating-company defense. That said, the firm does litigate both sides: Chambers-adjacent docket sources show Pehrson representing Atmos Fragrance, Inc. and an individual defendant in Pura Scents, Inc. v. Atmos Fragrance, Inc. (D. Utah, 2:24-cv-00958), a patent infringement defense, and Capana Swiss Advisors AG v. Rymark Inc. (D. Utah) shows the litigation group handling complex commercial and counterclaim work outside patents. Net: the tracked record says plaintiff-side only, but the public record is more balanced than the one-appearance count suggests. The single tracked case is listed without a caption, so no case name can be attributed to it.

PTAB / IPR practice. I found no evidence of a meaningful IPR or PGR practice — no petitions or patent-owner defenses attributable to the firm surfaced in searches. The closest PTAB-adjacent item is Ex parte Dopker (Appeal 2022-000424), an ex parte prosecution appeal on a Boeing aircraft stringer-frame application that KB&A prosecuted to a decision affirming-in-part — that is appellate prosecution work, not AIA trial practice. If the firm conducts IPR work, it is not publicly visible at any scale. Additionally, the firm's TTAB activity is documented (e.g., a 2023 notice of appearance for Maduro Distributors in Monster Energy Co. v. Maduro Distributors, Opp. No. 91286741), so the contested-proceedings work it does show sits at the trademark, not patent-trial, end.

Key partners. Four names are reasonably sourced. Brian C. Kunzler is the founder, a registered patent attorney and electrical-engineering background, repeatedly listed in Super Lawyers for IP (most recently 2026). Chad S. Pehrson leads litigation/patent disputes — a registered patent attorney admitted in Utah, California, and Colorado, with an M.S. in chemistry and a Vanderbilt J.D. (2008); he joined from Parr Brown Gee & Loveless in 2021 and is the sole attorney in the tracked appearance. Paul Sampson joined the litigation section the same year from a D.C. trial boutique and a top-10 "big law" firm, with biotech, pharma, and consumer-products experience. Marcia Fuller Durkin is a litigation partner who previously practiced at a national firm in Washington, D.C. and New York. R. Jeremy Adamson and Scott Hilton also appear as litigation/prosecution partners, and Perry S. Clegg, a registered patent attorney, signed KB&A complaints in the Modern Font Applications matters in 2019 — though by 2022 some of that work was being handled through Johnson & Martin, P.A., so his current affiliation with KB&A should be confirmed before relying on it.

Caveat on sourcing. The authoritative case list here contains only one appearance, so it understates the firm's public litigation footprint; conversely, the public matters I found (Modern Font Applications, Pura Scents, Capana Swiss) are drawn from dockets and trade press, not from the tracked dataset, and the firm does not appear on AmLaw or Chambers rankings. Rankings noted above are individual attorney recognitions (Super Lawyers), not firm-level rankings.
