Rotochoks??????
What happened to them. My nephew just bought a new trailer and was asking about mine so I tried to show him where to get them and the web site is gone. Did they go out of business?

The patent is 5,148,158, filed in 1991, issued October 27, 1992. "Vertically disposed wheel chock for tandem wheels".
Well, here is the bad news: It has expired, since it has been 20 years since the file and issue date. Any legal wrangling over who owns the patent is pointless now.
