Problem
Patent disputes often hinge on evidence buried deep in prosecution histories, where a single scope-narrowing statement can shrink a claim at trial and collapse damages. Attorneys also miss contradictions between arguments made at the PTAB versus district court, losing settlement leverage. Reconstructing the full record across multiple venues is time-consuming and error-prone, leading to millions in trial exposure and wasted effort per matter.
Solution
LexDana provides a semantic memory layer for patent litigation, enabling attorneys to ask natural-language questions and receive cite-anchored answers drawn from the full prosecution and litigation record. The platform reads and indexes filings across ANDA/Hatch-Waxman, PTAB, district court, ITC, and Federal Circuit proceedings, resolving parties, attorneys, and arguments into a unified claim graph. Deep Research capabilities go beyond structured fact tables to read the actual filings, extracting what each side argued and how claim terms were construed across venues. Every answer is cited to the specific document, page, and line, allowing attorneys to verify the source and trust the result. The platform also offers analytics on filing trends, win rates, judge patterns, and expert declarants, plus a live demo showing a complete Hatch-Waxman matter spanning prosecution, district court, and the Federal Circuit.
Target Audience
Primary customers are patent litigators, patent prosecution attorneys, and in-house IP counsel at pharmaceutical companies and law firms handling high-stakes patent disputes, particularly those involved in Hatch-Waxman and PTAB proceedings.
