1. Sample Patents Queries

For the following queries, we will restrict our search using the keyword nanotubes. You can of course change that, so to explore other topics too.

TOPIC = "nanotubes" #@param {type: "string"}

Searching patents by keyword

We can easily discover patents mentioning the keyword nanotubes and sorting them by most recent first.

df = dsl.query(f"""
search patents
    in title_abstract_only for "{TOPIC}"
return patents[basics+jurisdiction+legal_status]
    sort by publication_date limit 200
Returned Patents: 200 (total = 33135)
