Context

Roadmap item: P2 Backend — analyze_single_patent prerequisite

analyze_single_patent constructs the path patents/{patent_id}.pdf and reads from disk, but does not first download the PDF. If the file is absent (e.g. first-time analysis), the call fails silently or raises an unhandled file-not-found error.

What to do

  1. At the start of analyze_single_patent, check whether patents/{patent_id}.pdf exists.
  2. If the file is absent, call the appropriate download function to fetch and save it before proceeding.
  3. If a download function does not yet exist, create a minimal one that retrieves the PDF from SerpAPI or a stored URL and writes it to the expected path.
  4. Add error handling for download failures (network error, PDF unavailable) with a clear exception message.
  5. Add a unit test (with mocked download) confirming the download step is triggered when the file is absent.

Acceptance criteria

  • analyze_single_patent downloads the PDF if it is not already on disk
  • Download failures raise a descriptive exception
  • Existing on-disk PDFs are not re-downloaded
  • Unit test covers the missing-file path

[Repo Manager] This issue is already resolved. analyzer.py:analyze_single_patent() checks if the PDF exists on disk, and if not, looks up the cached PDF link from the database and downloads it automatically before reading. Closing as complete.
