Not trying to add fuel to the flame, but it would be interesting to know if any copyrights that are claimed to be protected are REGISTERED.
If the copyright is not federally registered, the copyright holder can't pursue statutory damages.
Without statutory damages, the holder would only be able to pursue actual damages.
Actual damages would be pretty hard to document if there are no revenue generated from the sale of the new product, and since the old product is no longer sold, there is no loss of revenue.
If they knowingly try to pursue a statutory damages claim, then you can file a counterclaim for abuse of process, and if you win, go back after them for malicious prosecution.
An IP lawsuit will costs both sides upward of $20k per month for at least 18 months in federal court. In this case I would expect that it will cost the plaintiff a lot more since he'd have to retain local representation in a foreign country.
As a businessman, I respect that Rick made an investment, however, there should be room for the little guys in this hobby that are just trying to make it better. No doubt that Rick is seen publicly as a bully and, even worse, a hindrance to the hobby. That's the real shame, because I'm sure he got into the hobby for the same reason as the rest of us... Reminds me of Anakin Skywalker.
