I wonder if Instagram has any patents that can be used in Facebook's patent war with Yahoo.<p>As a mobile social network, Instagram has no equal in the photo category.<p>It would be foolish to think that after a year and half a tech company with vc backing would not have at least 5 solid patents that could be used for defensive purposes.<p>Even if Instagram has patents that would in some way affect any yahoo holdings (specifically flickr), I don't see a $1 Billion value.
