Problem

The Analytics page shows aggregate metrics but no time-series view. Users cannot identify whether a company is accelerating or slowing its patent activity, or how its technology focus is shifting.

Work

  • Backend: add a GET /analytics/{company}/trends endpoint that returns patent counts grouped by filing year and technology category.
  • Frontend: add two charts to the Analytics page using a charting library (Recharts or Chart.js — whichever is already in the project or lighter to add):
    1. Line chart: patent filing count per year.
    2. Stacked bar or pie chart: technology category distribution per year.

Acceptance Criteria

  • The Analytics page shows a filing frequency line chart for the selected company.
  • The Analytics page shows a category distribution chart.
  • Charts update when the selected company changes.
