I have to wonder what small claims court judges would think of it. Get a few hundred cases filed across the US and the travel expense for Sony could be significant.
You can. It's called a levy or a writ of attachment depending on the jurisdiction. you can also do a till levy where you send the sheriff to go clean out their cash register.
However, 1) when attaching property, you generally need to do a sheriff's auction.
2) You better damn well be sure the property belongs to the correct corporate entity, eg SCEA, inc. and not Sony, inc., Sony of America,Inc., etc. - otherwise you've just committed a wrongful garnishment and now Sony can sue you for punitives.
