Context

Roadmap item: P2 Backend - analyze_single_patent assumes local file path

analyze_single_patent constructs patents/{patent_id}.pdf and reads from disk, but does not first download the PDF. Callers that invoke the method on a patent that has not been previously fetched will silently fail or raise an unhelpful file-not-found error.

What to do

Option A (preferred): Before attempting to read patents/{patent_id}.pdf, check whether the file exists; if not, trigger the download step automatically.

Option B (acceptable): Raise a clear, descriptive exception (e.g. PatentNotDownloadedError) with instructions, and document the prerequisite in the method docstring.

Acceptance criteria

  • Calling analyze_single_patent on a patent with no cached PDF does not raise an unhandled FileNotFoundError.
  • If Option A: the PDF is downloaded transparently before analysis.
  • If Option B: the exception message clearly describes how to obtain the PDF first.
  • The method has an updated docstring describing the prerequisite or the auto-download behaviour.

Resolved -- already implemented in the codebase.

analyzer.py's analyze_single_patent() already checks if the PDF exists on disk, and if not, looks up the cached PDF link from the database and downloads it via SERP.save_patents() before proceeding with analysis.

Closing as already resolved.
