David Alberti — Patent Litigation Practice Summary
Focus areas. Alberti's patent work centers on electrical engineering and computer technology: wireless and networking standards (3G/4G/5G essentiality analysis, Wi-Fi, radio transceivers), software and mobile application design/testing tools, semiconductors, and, through his firm's broader docket, medical devices and life sciences. His background is technical (B.S.E.E., University of Michigan), and the firm's Chambers profile describes a team of technically trained trial lawyers in software, hardware, semiconductors, wireless/networking, and medical devices. His tracked matters span mobile app software (Wapp Tech), consumer devices (IngenioSpec v. Apple), Wi-Fi/wireless SEP work (Google v. Wildseed Mobile), and financial-services software (Intellectual Ventures v. PNC and co-defendants).
Side preference. He is predominantly a plaintiff-side patent litigator. Of five tracked appearances, four are on the plaintiff/patent-owner side and one as back-up counsel on the defense side. His firm is explicitly built around representing patent owners in monetization litigation, and his D&O role description is consistent with that orientation; the single defense-side appearance (back-up counsel in the Google/Wildseed Mobile dispute) is the outlier and may reflect related IPR/district-court posture rather than a general defense practice. He does represent operating companies when they are the plaintiff (e.g., Google as a petitioner/plaintiff against Wildseed Mobile).
Firm context. Alberti is a founding partner of the Silicon Valley patent-litigation boutique now known as Alberti Lim & Tonkovich LLP (announced a name change from Kramer Alberti Lim & Tonkovich LLP in March 2026; the firm also previously operated as Kramer Day Alberti Lim Tonkovich, Kramer Day Alberti Lim Tonkovich & Belloli, and Feinberg Day Alberti & Thompson LLP, and related Feinberg Day Alberti Lim & Belloli names). Before that boutique lineage he practiced in the Feinberg Day orbit; the firm reports offices in Silicon Valley, New York, Washington, D.C., and Austin.
Notable matters. The most prominent result is Wapp Tech Ltd. Partnership v. Seattle SpinCo, Inc. (E.D. Tex., No. 4:18-cv-469): a March 2021 jury returned a $172,554,269 verdict on willful infringement of three mobile app-design patents — reported as the largest verdict in the Sherman Division's history — with Alberti named on the trial team (Law360; National Law Journal "100 Largest Verdicts"). The court later declined to enhance damages, and the case reportedly settled for a high-eight-figure sum. He was also trial counsel on the Intellectual Ventures I & II v. PNC Financial Services Group bank-defendant litigation (E.D. Va. and W.D. Pa.), one strand of IV's multi-defendant bank campaign. On the defense-leaning side, he appeared for Apple in IngenioSpec v. Apple and for Leica Microsystems in Regents of the University of Michigan v. Leica Microsystems (N.D. Cal.), which ended in a January 2025 judgment of non-infringement for Leica.
PTAB / IPR. He appears in PTAB proceedings — typically as back-up counsel of record for patent owners and petitioners in IPR matters (USPTO Reg. No. 43,465) — including filings in the Google/Wildseed Mobile and Adaptive Spectrum/Charter-related disputes. The firm advertises consecutive IPR victories and regular PTAB, Federal Circuit, ITC, and district-court appearances; the record here supports recurring PTAB involvement rather than a claim of first-chair lead status in every proceeding.
Bar and education. Admitted in Michigan (1996) and California (2002); registered to practice before the USPTO; admitted to the Federal Circuit. B.S.E.E., University of Michigan (1993); J.D., Wayne State University Law School (1996).
Note on sourcing: biographical details come from the State Bar of California profile, Martindale, and the firm's own materials. The firm's public descriptions vary as to its founding year (2010 vs. 2011). I did not find a reliable public source quantifying the number of IPRs in which he personally served as lead counsel, so that point is stated conservatively.
