Nikon has taken Sigma seriously and sued them for US$ 116 million and the Tokyo district court ordered Sigma to US$ 14.5 million, for patent infringement case for lenses with VR technology. Here is teh summary of judgement as posted by Nikonrumors site:
Here is the summary of the judgment:

"Nikon obtained the patent related to VR technology in 2002. The content of the patented invention relates to technology wherein a vibration detection device, which detects the amount of camera vibration at angles around photographic objects, prevents the influence of vibration of a motor for lens and thereby allows more accurate photo shots. Sigma affirms that the scope of the patented invention does not include any functions which reduce the influence of camera shake. However, Mr. Osuga, the Judge in Chief, states that the effects of the invention in Nikon’s specification is described as “it allows image blur to be reduced” and that the specification clears that it includes camera shake. Thus, Mr. Osuga stands for Nikon’s assertion. In addition, Mr. Osuga points out that image blur prevention system requires various control functions, and he states that this patented invention of Nikon’s should be rewarded based on the contribution of the patent to the defendant’s products, that is 15%. Therefore, the Tokyo District Court calculated profits earned by Sigma to be a maximum of 10.1 billion JPY, and found compensation of damages to be 15% of the profits of the accused products earned by Sigma."

That really seems unjust!  Canon has image stabilization too, how come Nikon isn't suing them?
I guess the little guys are easier to target ;D

Indeed, amazing how things in real life translate back from the playground in school?  Maybe this will make Sigma ripe for a takeover...by Canon!!

Actually Nikon was the first to come up with image stabilization in 1994, in a 38–105 mm f/4-7.8 zoom lens built into the Nikon Zoom 700VR (Zoom-Touch 105 VR) camera.
Canon produced their first Image Stabilized lens (EF 75-300mm f/4-5.6 IS USM) in 1995
I think what Sigma copied was the 2002 "version" of Nikon's VR technology.
