As some people know, that they have copied code from other websites to put on their own, and it was legal, per se.
But now the W3c standards, were always patent free, but now it seems that some future standards of code, you may have to pay for. Now for most people, this doesn't affect them. But for people like webmasters, this could be a future determent for using new code to enhance your web site.
