Recognition Highlights Individual Excellence in High-Stakes PTAB Proceedings

Alberti Lim & Tonkovich LLP, and co-founder and partner David Alberti, have earned recognition in Patexia’s recently published Insight 261, “Leading PTAB Practitioners by Activity and Performance.”

Analyzing over 5,650 attorneys active in Inter Partes Review, Post-Grant Review, and related proceedings from July 2020 through June 2025, the report ranks David in the top 4% of all evaluated practitioners based on a combination of activity and performance metrics.

The Insight focuses on individual attorneys who combine significant caseload volume with consistent results — emphasizing the strategic demands of drafting petitions/responses, navigating PTAB panels, and coordinating with parallel litigation. David’s recognition reflects his deep technical mastery and client-focused approach to protecting patent owners in complex proceedings.

“These rankings from Patexia underscore the value of experience-driven, technically rigorous advocacy on behalf of patent owners, which our team provides” said Mr. Alberti. “It’s rewarding to see our team’s commitment to every case reflected in independent, data-driven analysis.”

“Every recognition we earn from Patexia is a reflection of the same commitment — technically rigorous representation, built entirely around the patent owner. That is the standard this firm was built on and what we bring to every matter,” said Russell Tonkovich, a partner at Alberti Lim & Tonkovich LLP.
