Once in, I select Publication number. You will have to do this with all 5 Parent patents seperately. The numbers are as follows.
20100150138 LI 20100150328 RBR 20100172345 E911 20110122827 Mobile Gateway 20120170574 UI
Once you are looking at a parent patent data screen, click on "Continuity Data" along the top row of tabs, it is the 6th tab from the left. Then you will see two titles below, one will say "Parent Continuity Data", the second will say "Child Continuity Data", below "Child Continuity" you will find a number in blue, for RBR you will see 4 of them as there are four child patents or applications for RBR, the second one is patented.
Once you have selected an application to look at, click on "Image File Wrapper". This will bring up a list of all the documents filed recently. Click the check box next to the document and then hit the PDF box in blue at the top right of the page, if you just click the document, it will only open the first page.
As a side note, it appears they have filed a number of documents for the recently approved LI child for further examination.
