Searching for Patent Assignees (continued)

We see that there are seven different entries with Oddzon. Note that some entries spell out the word PRODUCTS and others abbreviate the word. We can now...

Step 2:

SELECT the E-numbered lines that contain variations for the patent assignee Oddzon.

Because I don't know anything about Oddzon, I want to get all of the entries for Oddzon so I get all of the patents listed in the database. I will choose E numbers 1-7 and enter the command at the question mark prompt:

I press ENTER and the search looks like this.

?s e1:e7

I can use the same technique to search for inventors that I used for patent assignees. On the Bluesheet we can see that the prefix AU= is used for inventor.

Example:
?expand au=silverglate
?select E number(s)

Our search would look like the search below:

In Derwent World Patents Index (Files 350, 351, 352), you can also use IV= to retrieve all forms of the author name, including the complete spelling, where available.

Example:
Johnston Walker J
Johnston Walker James
Johnston, Walker James

Search Tip 4-1:

Names are sometimes abbreviated in the database index. To make sure we retrieve all entries, it is sometimes necessary to EXPAND using a shortened form of the name (e.g., Bell Tel for Bell Telephone Labs).

Example:
expand pa=bell tel

Sometimes we may have to EXPAND more than one time to retrieve all entries

Example:
expand pa=ibm
Expand pa=international business mach
