Patent Searching For New Inventors - Searching By Patent Number

Patent Number Searching On The Advanced Search Page

Patent number searching on the advanced search page

Above you can see an example of the Advanced Search Page.

I filled my example patent number 5,470,270 in the query box. However, since this is a page that allows you to search for a patent by: number, inventor's name, claims, title of invention, and many more ways. I had to fill in the query box using PN/5,470,270.

The PN stands for patent number and a backslash / is added before the number. Design patent D265,332 would be written PN/D265,332. These special codes tells the database if I am searching by number, inventor's name, title, etc. All the different codes are listed on the Advanced Search Page.

There is also a drop down menu box for selecting what years you want your search to cover.
