Step 3 - Conducting The Search For A Patent Using Keyword(s)

When you search for a patent enter the keyword(s), developed in Step 2, individually or together using Boolean search statements into the search query box with the appropriate field. The available fields vary from database to database when you search for a patent, however the most common are:

-       Title – searches for keyword(s) in the title of the patent documents

-       Title or Abstract – searches for keyword(s) in the title or abstract of the patent documents

-       Full text – searches for keyword(s) in the whole patent document

 

Figure 2 shows a Boolean search statement being typed into a search query box (when you search for a patent) with the Title or Abstract field on the Esp@cenet database.

In our experience, a good place to start when you search for a patent is to search in the Title or Abstract field. Also when you search for a patent, searches should be started as broadly as possible and then be narrowed down.  For example, if you search for a patent on a new rotary engine with a new valve system, the broad search statement might look like this when you search for a patent:

(car OR vehicle OR automobile) AND (motor OR engine)

While the narrow search statement might look like this when you search for a patent:

(car OR vehicle OR automobile) AND (motor or engine) AND rotary AND valve

Figure 3 shows a typical search result page from the Esp@acenet Database when you search for a patent. The top of each search result page displays the number of documents found and the keyword(s) used. Please note that the Esp@cenet database only allows you to view up to 500 documents in each search and thus when searching for a patent we recommend narrowing down your search statements until your results are under 500 documents.
