LexData-driven PTAB rankings — coming 2026.
PTAB rankings covering petitioner-side and patent-owner-side representation across IPR, PGR, and CBM proceedings. Built on the full PTAB E2E dataset with institution and final-written-decision outcome tracking. The first edition publishes in 2026.
Methodology in draft. First edition: 2026.
Built on PTAB E2E data.
Every signal is computed from the full PTAB E2E dataset across all IPR, PGR, and CBM proceedings. Petitioner and patent-owner counsel are tracked separately, with institution decisions, Fintiv denials, FWD outcomes, and rehearing patterns all extracted.
Ranked on activity. Measured on performance.
Six performance signals across both petitioner-side and patent-owner-side practice. Each signal accounts for the unique dynamics of the PTAB — discretionary denials, Sotera stipulations, MTA practice, and the appeal-to-CAFC arc.
Petition volume
Weighted participation across all IPR, PGR, and CBM petitions — petitioner and patent-owner sides tracked separately.
Institution rate
Petitioner-side: rate of institution. Patent-owner-side: rate of successful POPR denial.
FWD outcomes
Petitioner: unpatentable-claim rate at FWD. Patent owner: claim-survival rate. Both weighted by claim count.
Procedural strategy
Use of Fintiv, Sotera stipulations, General Plastic, and other discretionary mechanisms.
Joinder & multi-petitioner
Joinder strategy and outcomes in multi-petitioner proceedings.
Appeal to CAFC
Outcomes when PTAB decisions reach the Federal Circuit — affirmance, reversal, and remand patterns.
Rankings backed by the public record.
Most rankings ask you to make a case for yourself. We already have the evidence.
