Summary

The Analytics page shows current aggregate metrics but has no time-series view. Trend charts showing filing frequency and technology category distribution over time would reveal innovation momentum.

Roadmap Reference

P3 Nice to Have -- Patent trend charts. See ROADMAP.md.

What to Do

Backend:

  1. Add a GET /analytics/{company}/trends endpoint returning time-bucketed data: patent counts by filing year and tech category breakdown per year.
  2. Query from existing patent/analysis records in PostgreSQL (group by filing_year).

Frontend:

  1. Install a chart library (Recharts is compatible with the existing React/Tailwind stack).
  2. Add a Trends tab or section within the Analytics page.
  3. Render a line chart for filing frequency over time.
  4. Render a stacked bar or area chart for tech category distribution over time.
  5. Support filtering by date range.

Acceptance Criteria

  • Filing frequency chart shows patent counts per year for the selected company.
  • Tech category chart shows the distribution of categories per year.
  • Charts render with accessible labels and tooltips showing exact values.
  • The trends section gracefully handles companies with fewer than 2 years of data.
