Basic Commands (continued)

Now that we see the list of patent numbers in our EXPAND list, we will SELECT the patent number for the Woosh.

Step 2: USE E REFERENCE NUMBER(S)

Use the E Reference number(s) to SELECT the desired entry(s).

Example:

s e4
s e1 or e4
s e2:e4

I enter the SELECT command and the appropriate E number(s) for the Woosh patent number at the question mark prompt and press ENTER. A set of records appears containing the number of records I found with my patent number search. There should be only 1 patent.

 
?s e1
      S1       1 PN="US 4944707"

Patent numbers have a consistent Dialog format that permits cross-file searching.

The example below illustrates several SELECT statements. I can use the SELECT command followed by any search terms or set numbers.

Command	Example	When to Use It
SELECT S	select pn=us 123456 s pn=us 123456 s s1	Use to create a set of records (e.g., s1) that contains the specified terms.

Search Tip 2-5

The term "patent" in a Dialog database refers to any published form or description of an invention, ranging from published unexamined applications to fully examined granted patents.

Therefore, it is best to think of PN as a Publication Number or Patent Number.
