Is there a way with 8.1.1.11 to remove the text "Innovation Pack 2013"?

I found in the Oracle Support site a document (DOC ID 1606916.1) that says:

on the Login Page, the "Innovation Pack 2013" is actually controlled by the C++ code and is not configurable.  They suggest using a CSS entry in the login.css file to hide it.  They do not go into any detail of what this line should be.  Looking at the HTML of the page, I do see that it is in a line that says it is in a <td> element with a class of "loginAppTitle".  So I added the following to the login.css

.loginAppTitle {

     visibility: hidden;

}

but it has no effect.  Has anybody been successful at removing the line opf text from the Login Page?  If so, can you please share how you did it?
