The Challenge
When every case is similar but none are identical.
Mass tort litigation involves hundreds or thousands of individual claims that share common defendants, products, or injuries — but each plaintiff has unique facts, medical records, and jurisdictional considerations. Managing this complexity at scale requires tools purpose-built for volume and pattern recognition.
Analyzing hundreds of similar cases
Mass tort dockets can include hundreds or thousands of individual claims. Each case must be evaluated for shared liability theories and individual merit, requiring analysis at a scale that overwhelms manual review processes and traditional document management.
Extracting patterns across plaintiff documents
Medical records, exposure histories, and product usage timelines must be extracted and compared across the entire plaintiff population. Identifying common injury patterns, causation timelines, and damages ranges requires structured analysis that goes far beyond keyword search.
Research across multiple jurisdictions
Mass tort cases are often filed in multiple state and federal courts, each with distinct procedural rules, Daubert standards, and substantive law. Keeping track of developments across jurisdictions and adapting arguments to local authority is a constant challenge.
Maintaining consistency across filings
When your firm files similar motions across dozens of courts, inconsistencies between filings can be exploited by opposing counsel. Maintaining uniform arguments, consistent fact characterizations, and aligned legal theories requires rigid quality control at scale.
How Irys One Helps
Analyze at scale. Litigate with precision.
Irys One combines multi-document analysis, cross-jurisdictional research, and organized matter workspaces to give mass tort teams the structure they need without losing the detail each individual case requires.
Multi-Doc Analysis
50 documents at once, structured output
Analyze up to 50 plaintiff files simultaneously against the same question set. Extract injury types, exposure dates, medical providers, and product identification across the entire corpus — with citations to source text in every answer.
Deep Research
Cross-jurisdictional legal research
Run Deep Research queries filtered by jurisdiction across 50M+ cases. Produce memo-quality reports comparing how different circuits handle causation standards, preemption arguments, or class certification criteria in your specific product area.
Matters
Matter organization at mass tort scale
Create separate matter workspaces for each bellwether case, MDL coordination, or state-court docket. Each workspace preserves its own documents, research, and drafts while the Library maintains shared resources that every matter can access.
AI Assistant
Pattern identification across cases
Ask the AI Assistant to identify commonalities across plaintiff documents — similar injury timelines, shared medical providers, overlapping exposure windows. The assistant works from the full context of every document in the matter workspace.
Template Builder
Consistent filings from master templates
Build master templates for complaints, discovery responses, and standard motions that maintain uniform legal theories and fact characterizations. The AI customizes each filing with case-specific details while preserving the core structure.
Cite Check
Verified citations across every filing
Before filing in any jurisdiction, Cite Check verifies that every citation is current, has not been overruled, and is valid authority in the target court. Avoid the risk of citing bad law across dozens of simultaneous filings.
Day-to-Day
Built for mass tort workflows.
From plaintiff intake to bellwether trial, Irys One supports the workflows mass tort teams rely on every day.
Plaintiff intake and case evaluation
A mass tort firm signs a new cohort of plaintiffs in a pharmaceutical litigation. The team uploads intake questionnaires and medical records into matter workspaces and uses Multi-Doc Analysis to extract key data points — diagnosis dates, prescribing physicians, dosage histories, and reported side effects. The structured output creates a case-strength matrix that helps the firm prioritize resources across the entire portfolio.
Bellwether preparation and research
The firm is preparing three bellwether cases for trial in an MDL. For each case, Deep Research produces jurisdiction-specific memos on causation standards, expert qualification requirements, and relevant jury verdict data. The AI Assistant identifies the strongest factual parallels between the bellwether plaintiffs and the broader population, helping the team select cases that will set favorable precedent for the rest of the docket.
Multi-jurisdiction motion practice
Opposing counsel files Daubert motions in four different federal districts. The team uses the Template Builder to create a master opposition brief with the firm's core arguments on reliability and methodology. For each jurisdiction, Deep Research identifies district-specific authority and the Drafting Assistant customizes the opposition with local citations and procedural requirements. Cite Check verifies every reference before filing in each court.
