It also holds Derwent World Patents Index records, with edited titles and abstracts, for 50 key jurisdictions.	Scope of the data: Patsnap describes access to more than two billion structured data points covering patents, science, litigation and technology.
Search functions: Basic search handles keywords and common fields such as inventor or publication number. Advanced search adds query operators, detailed filters and tools to tag and manage documents, and its dense layout suits large screens.

Reliable results depend on the user writing a careful Boolean query.	Expertise required: This is a professional searcher tool, and the DWPI fields add a second vocabulary to learn.
