What Hacker News says?
Guessing (maybe generously?) at OP's meaning, claims were made in the past about VP8 being royalty free etc, and that turned out to be wrong. It's not clear how much we can trust them this time around. http://www.streamingmedia.com/Articles/News/-76781.aspx http://carlodaffara.conecta.it/an-analysis-of-webm-and-its-p... http://www.fosspatents.com/2013/03/patent-clouds-remain-over... http://www.fosspatents.com/2013/0…

HN discussionThat very link describes multiples places where VP8 does things different to H.264 and basically calls them idiots for not doing it the H.264 way yet doesn't connect this to the patent situation that he is simultaneously accusing them of being idiots about because it is too similar to H.264. He can't have it both ways. There's a more thorough discussion of this here: An analysis of WebM and its patent risk http://ca…

HN discussion> No one has patents on C or C++ AFAIK... Oracle is not complaining Google is implementing Java in Dalvik. Oracle is complaining they are implementing things too similar to stuff Oracle has acquired patents about. http://carlodaffara.conecta.it/oraclegoogle-the-patents-and-...

HN discussionEvery time I've read the paperwork that came with a device that was able to create H.264 files, the words in the paperwork prohibited me from creating H.264 files with that device and using those files for commercial use. If I wished to use those H.264 files in a commercial setting, I was required to make a separate agreement with MPEG LA. VP8 has no such restrictions. Google has said on multiple occasions that VP9'…

HN discussionIn fact being similar, but crucially different, to a published patented technique is apparently a good way to avoid both known and unknown patents, so this is a good thing: http://carlodaffara.conecta.it/?p=420

Some highlights: "Dark Shikari makes several considerations, some related to the implementation itself, and many related to its “patent status”.

HN discussionThis analysis hints, and another [ http://carlodaffara.conecta.it/?p=478 ] suggests more explicitly, that Google might be OK going forward if they recast/relicensed their Java implementation as a derivative of Sun's GPL'd OpenJDK.
