Frequently Asked Questions
AI significantly speeds up the process of finding relevant prior art—but it’s not a replacement for expert judgment. PQAI uses semantic search to go beyond keyword matching, helping you uncover patents that traditional searches might miss. Most teams use it to accelerate discovery and reduce blind spots, then apply expert review for final decisions.
Great question—and important to understand.
- PQAI helps you search and analyze prior art quickly
- InspireIP helps you structure, evaluate, and manage ideas through the patent process
In short: PQAI = search and InspireIP = workflow
They work best when used together.
When you unlock full access (PQAI+), you get:
- Expanded prior art results
- Deeper similarity insights
- Ability to save and revisit searches
- Exportable data for review and documentation
This helps you move from quick exploration → serious evaluation.
You can run searches using PQAI independently.
However, if you want to structure your findings, evaluate patentability, and prepare disclosures, you’ll benefit from continuing in InspireIP.
