Ogg Theora
Ogg Theora is a video format, for which one of the core goals is to be free from patent problems.
Apple raised the concern the concern that patent holders might exist but might be staying silent, ready for a patent ambush if Theora becomes widely used.[1]

Vague, unsubstantiated threats
Patent licensing group MPEG-LA have made vague, unsubstantiated claims about that all video formats infringe their patents:
no one in the market should be under the misimpression that other codecs such as Theora are patent-free. Virtually all codecs are based on patented technology, and many of the essential patents may be the same as those that are essential to AVC/H.264. Therefore, users should be aware that a license and payment of applicable royalties is likely required to use these technologies developed by others, too. MPEG LA would consider offering on additional licenses that would make these rights conveniently available to the market under a single license as an alternative to negotiating separate licenses with individual patent holders.[2]
