So this patent was filed September 11, 2013. There are two Youtube videos describing the same invention from April 2013 from two different people:



Would that be grounds to block this patent application being granted? What would I have to do to accomplish that?

    I'd update your post to a prior art request, then in a reply to that show the videos and explain how they do the same thing as in the application.

Note that the filing date of a patent application is not always the date by which prior art is measured. Here, the patent application in question claims the benefit of priority to a European Patent Application (EP 12184092.0) filed on September 12, 2012. So, the patent application in question has a priority date of September 12, 2012. In order to be considered prior art, the YouTube videos in question would have to be dated prior to September 12, 2012

The best type of prior art is that which has an effective publication date more than one year before the earliest priority date to which the patent in question is entitled. So, you really want to have prior art having an effective date of September 11, 2011 or earlier.
