Escapenet Patent Search - With Example Search Queries

What is Escapenet?

Escapenet.com (Escapenet) is a patent search platform, and is especially helpful at finding international patent documents. US and Foreign patents and patent applications can be found with Escapenet.

The proximity search operator is a useful search function in Escapenet

Similar to the Patent Public Search (the patent search platform provided by the USPTO), Escapenet provides plenty of options for conducting advanced searches.

One of the best tools Escapenet has for advanced searching is the proximity operator “prox/distance<nr.” This tool is a proximity operator which can be placed between search terms to find documents that contain the search terms less than “nr” words apart, independent of order.

An example of this operator being used is “house prox/distance<3 door,” which finds documents that have the term “house” and “door” less than three words apart in either order.

How search results are viewed in Escapenet

Search results are displayed on the left pane of the website, while documents from the search results are displayed on the right pane of the website.

You can navigate through the sections of a document by using the drop down menu located on the left of the document viewer. This drop down menu can be used to view the document’s drawings, descriptions, and original pdf.
