The design is so simple&#x2F;obvious that I believe many people could have come up with it independently. It seems a bygone conclusion that the Chinese company was intentionally stealing from the US one but that might not be the case. Under patent law it doesn&#x27;t matter if you invented something independently. I too would probably scoff at the correspondence from the US firm thinking it was some patent troll. I mean how do you patent a &quot;board on a rolling pin&quot;???
