Kramer Alberti Lim & Tonkovich

I'll research this firm before drafting.

Note on firm name: The case list is under Kramer Alberti Lim & Tonkovich LLP. As of March 2026 the firm announced a name change to Alberti Lim & Tonkovich LLP (branded "Alberti Lim"); the substantive entity is the same, so tracked appearances under the former name still apply.

Firm overview. Kramer Alberti Lim & Tonkovich LLP (now Alberti Lim & Tonkovich LLP) is a patent litigation boutique founded in 2010, headquartered in Silicon Valley (Burlingame/Foster City, CA) with additional attorneys in Austin, Texas, New York, and Washington, D.C. Its own announcements describe a team of roughly 20 technically trained patent litigation attorneys — a true IP boutique, not BigLaw and not a general-practice regional firm. The most concrete independent ranking I could verify is Patexia's 2023 Patent Litigation Intelligence Report (covering 2017–2022), which placed the firm among the top 50 most active and best-performing firms representing plaintiffs, and named partners Dave Alberti, Sal Lim, and Russell Tonkovich among the top 50 plaintiff-side patent litigators. I found no AmLaw or Chambers firm-level ranking for this outfit; treat size/attorney-count figures as firm-supplied.

IP litigation specialty. The firm's docket skews toward electrical engineering and computer-science arts rather than life sciences: mobile application development and testing software (Wapp Tech), wearable/head-worn electronics and audio devices (IngenioSpec), broadband and Wi-Fi/DSL network management (Adaptive Spectrum and Signal Alignment v. Charter, E.D. Tex.), LED backlighting and consumer displays (Polaris PowerLED v. VIZIO), semiconductors, streaming/VOD, cryptography, and microprocessor/memory architecture — the last several of which appear in the firm's own practice description and partner bios. It also advertises university and research-institution representation (University of Michigan, University of Virginia), a common patent-monetization client profile.

Side preference. Overwhelmingly patent-owner/plaintiff side. The tracked list shows 3 plaintiff-side and 3 defendant-side appearances, but the defendant-side entries are all the same dispute — Google LLC v. Wildseed Mobile — where the firm represented Wildseed, a patent owner defending against Google's declaratory judgment action and parallel IPRs. Read functionally, all six tracked appearances are patent-enforcement work (owner or plaintiff). The firm's own materials state it is "a firm of choice for plaintiffs seeking large recoveries in patent monetization," so practitioners should not expect a defensively oriented operating-company practice at scale. Notably, all six tracked appearances involve pro hac vice or local-counsel coordination, meaning the firm often teams with local counsel in venue.

Notable matters. Wapp Tech v. Capital One is the flagship tracked case; the broader Wapp campaign produced a reported $172.5 million jury verdict against Micro Focus (described in Wapp's own court filings as 100% of requested damages, with JMOL on validity) and a confidential settlement with JPMorgan Chase (E.D. Tex., dismissed with prejudice March 2025). I could not independently verify that this firm was trial counsel in the Micro Focus verdict — Sal Lim's bio lists Wapp Technologies as a former client, and the firm claims Top Verdicts recognition from the National Law Journal and Texas Lawyer, but the link is not documented in public sources I found. IngenioSpec v. Apple (W.D. Tex.) asserts head-worn/wearable device patents against AirPods and iPhone and has drawn multiple Apple IPR petitions; ASSIA v. Charter Communications (E.D. Tex.) is a pending plaintiff-side action. Firm-filed matters have also drawn E.D. Tex. § 101 motions to dismiss, so eligibility risk is a live issue in its campaigns.

PTAB / IPR practice. The firm works both sides of the Board at a boutique scale: it appeared as patent owner counsel in Google v. Wildseed Mobile IPRs (e.g., IPR2023-00246, with Andrew Hamill as back-up counsel, Sal Lim and David Alberti on mandatory notices) and defends the IngenioSpec patents in Apple's IPR2026-00142/143/144 filings. I found no public report establishing a specific IPR filing volume for the firm, so any "hundreds of petitions" characterization would be unsupported. Post-grant work appears to be a supporting capability rather than a volume-driven practice.

Practice leaders. David (Dave) Alberti and Sal Lim are the most visible names across tracked filings and PTAB papers — both co-founders, both named in Patexia's top-50 plaintiff list, with Lim also recognized in the 2025 Best Lawyers in America for IP litigation and holding an M.S. in electrical engineering. Russell S. Tonkovich is the third named partner and a frequent PTAB and E.D. Tex. signatory. Robert F. Kramer remains an active litigator whose name was removed in the 2026 rebrand.
