These keywords are semantically connected to your input, including system terms, application areas, and adjacent technologies. You can use these terms to refine your PQAI queries or copy them into other patent databases and advanced search engines
This tool is especially useful when you’re not sure what terminology the patent literature uses. It helps you think beyond your initial phrasing.
