Skater Dolly / Radiatus Patent?

[quanabee]

Hi Guys,

I'm new to the forum, but have been looking at the skater dolly for a while now. Do you think there is a patent on this? I was thinking of possibly starting a manufacturing process on it? Any thoughts?

P+S Techniks has a patent on their skater Mini and I have heard that they have shut people down that have copied their design.
Although if you made a dolly with a different enough design I'm sure you would be fine.
