This could be awhile. I took the US patents listed on at:
http://www.mpegla.com/avc/avc-patentlist.cfm
in
http://www.mpegla.com/avc/avc-att1.pdf
and checked their expiration dates.
The last ones expires in 2028. There maybe other patents that are not listed, and some that are listed may not actually be essential to the real date for H.264 being royalty free could be different.
Here is the complete list:
