US software companies got nothing on this guy:

Vladimir Osipov, from the southern Russian town of Yeisk, showed up at his local notary office in the Krasnoyarsk region with a document affirming his ownership of all the clouds in the air over Earth, the Novye Izvestia daily reported.

When my brother was six he claimed ownership of an entire crop dusting company, right down to the airstrip they used. Something tells me this guy's chances of enforcing his ownership rights are about as good as Jeff's were back then.
