HTML5 and video patents
HTML is the standard set by the W3C for how to write webpage markup. HTML5 was supposed to include a standard way to add video to webpages, but after lengthy discussions about software patents, the drafters announced on June 30th 2009 that they could find no freely implementable video format to recommend.
Here’s the challenge: Can [T]heora move forward without infringing on the other video compression patents?
A third option discussed was to use software from 20 years ago: MPEG-1.
HTML is an open standard and aims to be patent-free. Consequently, the risk of patent encumbrances is posing a real problem in extending HTML to provide a standard video interface.
