This is a legitimate USPTO API client for patent and trademark research. Static findings are false positives: detected patterns in markdown files are documentation code examples, not executable code. The network+credential access pattern is standard API client behavior for accessing USPTO government services.

Best Practices

  • Store your USPTO API key in the USPTO_API_KEY environment variable before use
  • Implement exponential backoff when hitting rate limits to avoid service disruptions
  • Use _text_* operators for text searches as they are more performant than _contains

Avoid

  • Do not hardcode API keys in scripts or share them in version control
  • Do not exceed the 45 requests/minute rate limit for PatentSearch API
  • Do not assume all fields are populated for every patent or trademark record
