Searching for Patent Assignees

Now, let's look at Brian's request again. He wants information on the patent assignee Oddzon. We can again use the EXPAND command in File 351 in case there is more than one spelling for Oddzon. Here's how it will look. Learn More

Step 1:

EXPAND using the appropriate prefix and term:

Tip 4-1

Enter the command at the question mark prompt and press ENTER.

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:

?b 351

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
