Use Case

Patent research involves analyzing multiple patent documents to understand prior art, technology landscapes, and competitive IP positions. Cowork can help organize and extract key information from patent files.

Example Prompt

I have downloaded 25 patents in ~/Patents/BatteryTech/ related to solid-state battery technology. Please:

1. Extract key information from each patent:
   - Patent number and filing date
   - Assignee/inventor
   - Abstract summary
   - Key claims (first 3 independent claims)
   - Technology classification

2. Create a patent landscape analysis:
   - Timeline of filings
   - Top assignees by patent count
   - Technology clusters
   - Potential white spaces

3. Generate patents_analysis.md report

What Cowork Does

Document Parsing: Extracts structured data from patent PDFs
Metadata Extraction: Identifies patent numbers, dates, assignees
Claim Analysis: Summarizes independent claims
Classification Mapping: Groups by technology area
Landscape Visualization: Creates timeline and cluster analysis
Report Generation: Compiles comprehensive analysis document
