Frequently Asked Questions

Does this prompt check for PCT national phase entry requirements?

This prompt focuses on direct CIPO filings and national phase applications already entered. For PCT 42-month deadline calculations and specific national phase formalities, use a separate PCT compliance prompt.

Can this analyze French language applications?

Yes, the prompt can analyze French text, but ensure your AI model has strong French legal language capabilities. For mixed applications, specify the language in the technical field context.

How does this differ from USPTO or EPO patent analysis?

This prompt specifically targets Canadian Patent Act sections (27, 28, 36) and CIPO examination practices, including Canada's unique approach to utility (Promise of the Patent doctrine history) and claim construction rules that differ from US claim interpretation.
