SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill eliminates slow, fragmented manual research when you need authoritative USPTO data for patents and trademarks, such as prior art discovery, prosecution history, ownership changes, and citation intelligence.

Core Features & Use Cases

  • Patent discovery with USPTO PatentSearch: Search granted patents and relevant pregrant publications by keywords, inventors, assignees, date ranges, and classifications to quickly build a prior-art set.
  • Prosecution history with PEDS: Retrieve transaction timelines and office-action-related events (including examination status and outcomes) to understand how claims evolved.
  • Trademark status & documents with TSDR: Look up trademark case status and prosecution details by serial or registration number for tracking and portfolio management.
  • Ownership and citation intelligence: Use USPTO assignment, citation, office-action, litigation, and PTAB-related APIs to support IP analysis and landscape assessment.
  • Use Case: You are performing IP due diligence for a technology area—start with PatentSearch to find relevant patents, then use PEDS to analyze prosecution outcomes and finally check assignments/citations to assess strength and relationships.

Quick Start
