AI copilot for patent drafting, prior art search, and office action responses
Generates jurisdiction-aligned claims and specifications from an invention disclosure, keeping figure references, chemical structures, and biological sequences consistent and giving attorneys full review and edit control.
Summarizes examiner objections per claim, maps each cited reference to claim elements, detects 101/102/103 issues, and drafts first-pass arguments, amendments, and interview guidance from the full application history.
Searches patent and non-patent literature across 100+ jurisdictions with filtering by jurisdiction, CPC/IPC class, assignee, and publication, returning similarity scores and AI novelty summaries.
Simulates an attorney-inventor interview with structured, context-aware questions so complete technical details and alternative embodiments are captured early and filings move faster.
Real-time AI answer engine and research workspace combining live web citations with frontier reasoning models.
Executes multi-step iterative web and document research across hundreds of sources, cross-checking facts and generating structured, citation-backed analytical reports that can be exported as PDFs or shared as interactive Perplexity Pages.
Lets Pro and Max subscribers switch dynamically between Perplexity's in-house Sonar models and top external models (including Claude 4, o3-pro, and Gemini) or compare multi-model reasoning outputs side by side.
Provides dedicated project workspaces where users upload local PDFs, spreadsheets, and text files, configure custom assistant instructions, and run queries that combine private document retrieval with live internet search.
Extends Perplexity from passive Q&A into agentic execution, turning high-level user requests into completed workflows, multi-tab browser actions, and automated data synthesis via the Comet ecosystem.
