Morse code on Norton Box labels?

I just noticed that "JVC" is printed in invisible, glossed Morse code on a lot of the labels (mostly UPC and serial number labels) that came with my 3-PC copy of NIS 2013.

 

After pulling out my old NIS2012 box, I noticed that it had "DLC" printed in the same place and in the same manner.

 

Does anyone else see this on their NIS boxes? If so, what's it for?
