PQAI: Patent Quality Artificial Intelligence

An AI-powered tool for running prior-art checks.

PQAI takes plain language invention description as input and finds similar prior work within patents and other technical literature. It uses a number of machine learning (ML) models to parse the input, find similar prior-art, and present the results. The ML models of PQAI have been trained on past patent examination records.
