Ex Parte

Ex Parte is an agentic litigation-intelligence platform for finding vulnerabilities in federal legal matters. It suits law firms, corporate counsel, litigation finance, insurers, hedge funds, and universities that need research tied to underlying records. The strongest case for it is source-linked forensic analysis; the main qualification is that trial access is restricted and every generated conclusion requires independent verification.

Overview

Ex Parte gives each matter a secure, permissioned workspace. Reports connect findings to source pages, lines, and citations, so a lawyer or analyst can follow an assertion back to the record instead of accepting an unexplained summary. That audit path is particularly useful when a finding must be reviewed by several people or defended in an investment or litigation decision.

Its corpus spans USPTO file wrappers, PTAB proceedings, PACER filings, court opinions and dockets, IEEE Xplore, ACM Digital Library, PubMed, and SEC EDGAR. Ex Parte describes an entity graph containing more than 2 billion entities and a knowledge graph mapping more than 2 billion relationships among patents, parties, counsel, judges, and outcomes. Such breadth is relevant to matters that combine legal, technical, scientific, and financial context, although graph size by itself does not establish that a particular finding is correct.

Key features

Forensic case analysis

Domain-specific agents examine examiner search logs, prosecution-history amendments, and mismatches between complaint allegations and patent specifications. These checks target weaknesses that broad document search can miss, making the platform more relevant to patent and complex commercial disputes than to casual case lookup.

Quality review and traceability

A dedicated QA agent checks each finding against primary sources before delivery, while the report's page, line, and citation links support human review. This is a meaningful control for teams that need an evidentiary trail, but it remains a review aid rather than a substitute for legal judgment.

Analytics across matters

Ex Parte covers judge analytics, outcome analytics, attorney and party data, and case-trend analytics within a federal jurisdiction scope. The mapped relationships between judges, counsel, parties, patents, and outcomes can help teams frame litigation strategy or evaluate exposure alongside the underlying filings.

Pricing

Ex Parte uses paid, custom pricing, with pricing available on request. Enterprise subscriptions are governed by a separately negotiated Master Services Agreement, so buyers should expect commercial, seat, usage, and service terms to be settled during that process rather than through a public self-serve checkout.

Free trial

A free trial requires no credit card, and verified law-firm and corporate domains receive immediate approval. It is for internal evaluation only: access may be rate-limited or suspended, with no service levels or support. Trial users must not submit sensitive or regulated data; no data-processing addendum or security warranty applies, and customer input may be permanently deleted after the trial period. Generated outputs are probabilistic, may contain errors, are not legal advice, and must be independently verified. Those conditions make the trial suitable for controlled, non-sensitive evaluation—not live matter data or unsupervised work product.

Platforms

Ex Parte is delivered through the web, which fits teams working from browser-based matter workspaces but does not provide a native desktop or mobile platform.

Who it's for

Law firms and corporate legal departments are the clearest fit when they need a repeatable way to investigate case vulnerabilities and inspect the supporting record. Litigation-finance teams, hedge funds, insurers, and universities may benefit when legal outcomes must be assessed alongside technical, scientific, or financial evidence. It is a poor choice for users seeking a lightweight public-docket viewer, a consumer legal app, or analysis that can be accepted without attorney review.

Pros and cons

Pros

• Source-linked findings: Page, line, and citation references make conclusions easier to audit against primary material.
• Focused forensic agents: Examination of search logs, prosecution amendments, and pleading-to-specification mismatches addresses concrete litigation vulnerabilities.
• Broad cross-domain graph: Legal, technical, scientific, and financial sources support matters that cross conventional research boundaries.
• Dedicated quality check: A QA agent provides an additional primary-source review before delivery.
• Permissioned matter workspaces: Separating work by matter supports controlled collaboration.

Cons

• Custom pricing: Buyers cannot compare a published subscription price or plan limits before engaging sales.
• Trial restrictions: No support or service levels, possible suspension or rate limits, and deletion of trial input limit what can be evaluated safely.
• Data restrictions: The trial excludes sensitive and regulated information and carries no data-processing addendum or security warranty.
• Probabilistic output: Findings can be wrong and require independent verification, so the platform cannot replace legal review.
