The IP-litigation evidence platform for boutique firms. Discover infringement with autonomous investigation. Capture it with court-ready chain of custody. Monitor it continuously.
The problem
Today, boutique IP firms lose billable hours, and sometimes cases, to the laborious, error-prone process of manually capturing and archiving digital evidence. Screenshots lack legal weight. Web content disappears overnight. Courts increasingly scrutinise chain of custody.
Counterfeit listings, infringing posts, and domain content disappear within hours of detection, often before you can capture it.
Courts and opposing counsel increasingly challenge unverified screenshots. You need timestamped, cryptographically sealed capture.
Paralegals spend 3–5 hours per matter manually documenting, formatting, and organising evidence packages. Perdura does it in minutes.
Perdura organises every IP-litigation engagement around three equal-weight workflows. Use them on their own or stitch them together. Discoveries flow into evidence, evidence flows into monitoring.
Autonomous investigation across the open web. A planner/executor agent searches, opens pages, pivots off WHOIS and certificate-transparency signals, runs reverse image search against suspect product photos, and surfaces a triaged list of Targets (sites, listings, accounts) for your team to review. Investigates using your team's own authenticated accounts through shared firm Personas, every session logged.
Point-in-time, court-ready evidence. Every capture is cryptographically sealed with an RFC 3161 timestamp from an accredited TSA the moment it's taken: full-page screenshot, HTML source and network video, assembled into a verifiable bundle ready to file.
Continuous watchers with Change Detection. Schedule recurring captures on infringing URLs, marketplaces, and social accounts; Perdura alerts you the moment a page changes, a listing reappears, or new evidence surfaces, and re-captures it on the spot.
Targets are the cross-pillar currency. Anything Discover surfaces can be promoted to Capture for court-ready evidence, or to Monitor for ongoing surveillance, with full provenance from artifact back to the original discovery.
Built specifically for IP attorneys and their paralegals, not generic web archiving.
Describe a goal in plain English; the agent plans, executes, and replans. Eleven tools across discovery (web, shopping, news, images), reading (HTTP and full browser), and pivoting (reverse image search, RDAP/WHOIS, certificate transparency). Parallel execution opens up to ten browser sessions at once. Shared firm Personas let the agent investigate using your team's own authenticated accounts, with every session logged in the audit trail.
Every capture is cryptographically sealed with a trusted RFC 3161 timestamp the moment it's taken. Tamper-evident, verifiable, and designed to satisfy the evidentiary standards of FRE 901 and 902 in the US and the eIDAS framework in the EU.
Generate formatted PDF bundles with embedded metadata, hash verification, and chain-of-custody documentation, ready to file or send to opposing counsel in one click.
Recurring capture schedules with Change Detection between runs. When a watched listing changes price, a takedown gets reversed, or a counterfeit reappears under a new URL, Perdura alerts you, and re-captures the new state with a fresh TSA-stamped seal.
Every engagement lives inside a Matter, the container that ties together its discoveries, captures, and watchers. Search, tag, and export across matters; purpose-built for litigation boutiques running 10–50 in parallel.
Every capture, export and access is logged in a tamper-proof audit record. Full traceability from collection through to courtroom, with no gaps in the chain.
State the goal in plain English, for example "Find counterfeit Acme handbags on EU marketplaces and map the operators behind them", and the agent plans, executes, and replans across the open web. Every step is visible: search queries, pages opened, WHOIS pivots, certificate transparency lookups. Discoveries land as triaged Targets in the matter.
Investigation Agent · TargetsOne click promotes a Target to a Capture run. Full-page screenshot, HTML source, and network video are acquired through a clean browser session, optionally using a Persona so logged-in views are preserved, then cryptographically sealed with a SHA-256 hash and an RFC 3161 timestamp from an accredited TSA the moment the capture completes.
RFC 3161 · SHA-256 · PersonasPut any Target, or any standalone URL, on a recurring schedule. Perdura compares each run against the last and surfaces structural changes: price moves, content swaps, takedown reversals, new listings on the same seller. Material changes trigger an alert and an immediate fresh capture, sealed and added to the matter.
Change Detection · Alerts · Auto re-captureReview the matter's captures, add metadata, and export a formatted PDF with every artifact, hash, timestamp, and chain-of-custody record, including provenance back through the Target that produced it. Ready to file, serve, or present in discovery.

Perdura was designed from the ground up to meet the evidentiary standards of IP litigation, not retrofitted from a generic archiving tool.
Designed with practising IP litigators during the design partner programme.
Perdura is built by Daniel Grech, a software engineer and founder with 15 years in software and AI, including years building online brand protection and merchant monitoring systems. He started Perdura after watching law firms lose time and cases to evidence that could not prove its own integrity.
