## Error Handling

All errors return JSON with `error` and `code` fields. No exceptions thrown.

| Code | Meaning |
|---|---|
| PATENT_NOT_FOUND | Patent ID doesn't exist (404) |
| AUTH_ERROR | Invalid/expired API key (401/403) |
| MAX_RETRIES_EXCEEDED | Network failure after 3 retries |
| NO_DESCRIPTION | Patent has no description text |
| PARSE_ERROR | HTML parsing failed |
| NO_PDF | No PDF available |
| DOWNLOAD_ERROR | PDF download failed |
| MISSING_QUERY | No search query provided |
| MISSING_ID | No patent ID provided |

Auto-retry: 3 attempts with exponential backoff (2s, 4s, 8s) on 429/5xx errors.
Rate limit: 1 second between requests to avoid triggering anti-scraping.
Timeouts: 10s connect, 30s max per request, 60s for PDF downloads.

## FAQ

**Q: Why are some fields empty?**
A: Different countries have different patent page formats. Some patents may have incomplete data, or the description may not be digitized.

**Q: Can I batch-fetch patents?**
A: Yes, loop through IDs. Respect the 1s rate limit. Free tier = 100 calls/month. Cached results (same query within 1h) are free.

**Q: How to get PDF?**
A: `bash scripts/patents.sh pdf "US11734097B1" output.pdf`

**Q: Chinese vs English patents?**
A: Chinese pages (patent/CNxxxxxx/zh) have native Chinese content. English pages have machine-translated content. Use `--language CHINESE` for search.

**Q: Patent ID formats?**
A: Country code + number + type suffix. Examples: CN106484775A, US20180232442A1, EP2264377A2, USD975937S1 (design), JP2020123456A.
