Can I expect any support from the EPO?

The EPO can help you with:

  • Any issue directly related to registration
  • OPS testing (see also “EPO OPS API Documentation” in the Developer’s area)
  • Identifying the requests or services best suited to your needs
  • Data-content issues (coverage, formats, query definition)
  • Support in the case of disruption to services

The EPO cannot help you with technical aspects such as the use of OAuth authentication, programming or code analysis.
