Introduction
Teri —
I would like to see what additional patents have been granted to Oddzon, the patent assignee for the Woosh. I'm not familiar with this company. Do they have any patents in the last year?
Thanks,
Brian
For this search I want to see if Oddzon has any patents outside the U.S., as well as U.S. patents.
I will use File 351, Derwent World Patents Index for this request. This file provides information on patents issued by over 40 patent-issuing organizations internationally.
It wouldn't make any sense to try searching for an assignee, like Oddzon, using the patent number label (PN=). We will need to consult the database Bluesheet again to see what field label is used for patent assignee.
