Mark Fowler

I'll research this attorney before drafting.

Now let me verify specific case outcomes and IPR work.

Let me check prior firm history, PTAB work, and the remaining tracked cases.

Mark D. Fowler — Patent Litigation Practice Summary

Focus areas. Fowler is a patent trial lawyer whose docket is concentrated in electronics and semiconductor technology: semiconductor memory and SRAM, bus termination circuitry, silicon TV tuners, optical disc drives, enterprise storage, mobile power management and touchscreens, media/streaming delivery over Wi-Fi networks, and consumer smart-device features. The tracked case list reflects this — the Maxell, SoftView, and VB Assets matters all involve consumer electronics, smartphone functionality, or voice-assistant software — and DLA Piper's own experience list adds ITC Section 337 work on semiconductor and display technologies. His practice is primarily defense-side district court and ITC litigation rather than Hatch-Waxman/pharma or mechanical work.

Side preference and firm context. Of six tracked appearances, five are on the defendant side and one on the plaintiff side, and the defendant work is overwhelmingly representation of large operating companies (Samsung, Toshiba, Apple, GSI Technology, Silicon Laboratories, Sun Microsystems, CSR) against NPE/PAE plaintiffs. The lone plaintiff-side entry, Samsung Electronics Co., Ltd. v. Maxell, Ltd., is still an operating company asserting against another operating company, not NPE prosecution — so the profile is a defense-oriented practice that will take the plaintiff's side in a commercial dispute. Fowler is a partner in DLA Piper's Palo Alto (East Palo Alto) office, co-chair of the firm's global IP and technology group, and a member of the firm's Global Board and Executive Committee. Chambers USA/Global ranks him Band 3 for ITC Section 337 work and Band 4 for California patent litigation; he also appears on Patexia's top-100 patent litigator and ITC lists. All six tracked appearances are DLA Piper; no prior-firm history was reliably sourced, and I did not find a verifiable pre-DLA Piper affiliation.

Notable cases and outcomes. The most prominent tracked matter is Maxell, Ltd. v. Samsung Electronics Co., Ltd. (E.D. Tex.), where Fowler was on the DLA Piper trial team that defended Samsung against a May 2025 jury verdict of roughly $111.7 million. In September 2025 Judge Robert Schroeder III granted Samsung's motion for judgment as a matter of law, finding insufficient evidence of infringement on all three asserted patents and invalidating claims in two of them, and denying Maxell's requests for enhanced damages, interest, and a permanent injunction (the opinion explaining the ruling was unsealed September 29, 2025). Law.com's "Litigator of the Week" column recognized the DLA Piper Samsung team in November 2025. Parallel PTAB proceedings went largely Samsung's way. On the Federal Circuit side, Fowler led the Apple trial team in Aylus Networks, Inc. v. Apple Inc., culminating in the precedential 2017 decision (856 F.3d 1359) holding that patent-owner statements made in IPR preliminary responses can support prosecution disclaimer in district court — a ruling the firm's bio reasonably describes as the wireless-communication defense that produced summary judgment of non-infringement. His firm bio also reports a successful defense against a $500 million streaming-media claim in the Northern District of California (jury non-infringement, affirmed on appeal) and multiple ITC no-violation outcomes (Cresta Technology, Cypress v. GSI, Freescale v. Zoran/CSR, TPL v. Samsung). Those firm-bio descriptions are not independently verified here; I did not find court records confirming the specific party names in the $500 million matter.

PTAB/IPR experience and credentials. The tracked appearance data is district-court/ITC focused and does not itself show IPR proceedings, so his PTAB footprint should be treated as moderately rather than firmly sourced: DLA Piper filings in Qualcomm Inc. v. Monterey Research LLC (IPR2020-01492) list Fowler among patent-owner counsel, indicating he has appeared in IPR proceedings on the patent-owner side, and the Maxell/Samsung disputes he litigates have run parallel PTAB campaigns. He is admitted in California (State Bar No. 124235, admitted December 1986) and holds a J.D. from Stanford (1986) and an A.B. from U.C. Berkeley (1983).
