Summary

analyze_single_patent constructs the path patents/{patent_id}.pdf and reads from disk, but does not download the PDF first. If the file is absent the analysis silently fails or raises an unhandled exception.

What to do

  • Check whether patents/{patent_id}.pdf exists before attempting to read it.
  • If the file is absent, call the existing PDF download step (from serp_api.py or wherever the download logic lives) to fetch it first.
  • If the download fails, surface a clear error rather than proceeding with a missing file.
  • Add a brief docstring documenting the expected preconditions.

Acceptance criteria

  • Calling analyze_single_patent for a patent not yet on disk triggers a download automatically.
  • A missing patent that also cannot be downloaded raises a descriptive exception (not a silent failure).
  • An existing PDF is not re-downloaded unnecessarily.
  • Covered by at least one test (mock the download call).

Triage: RESOLVED

This issue has been fully implemented in the fork main branch (merged via PR #55).

Evidence:

  • analyzer.py analyze_single_patent() (line 109-161) checks if the PDF exists on disk, looks up cached metadata for the PDF link, downloads if available, and raises a descriptive FileNotFoundError if download is not possible.
  • The method has a full docstring documenting preconditions and raises.

All acceptance criteria are met. Recommending closure.
