Quick update on the rotary valve cylinder head project. I got a nastygram from an attorney accusing me of patent infringement. Looks like nothing more than non-factual scare tactics to try to enforce expired patents.
Here is a copy of the letter I received.
This is the second time I have been falsely accused of copying someone else patent. The first time was by a youtuber that had some suspicions, I appreciate his feedback and no hard feelings. The actual patent holder in this case I had been in contact with previously and he confirmed my design was not an infringement.
This time however I have apparently really got someone excited as to receive a letter from an attorney before they did their homework. Look, before you go blindly accusing people might give them a call and get your facts straight. I would be happy to chat with anyone who has a serious concern, as infringing on someone else’s intellectual property or breaking the law is the last thing I want to do.
Mr Coates, like I said in the video you are invited to come check out what I have been working on for yourself or at least give me a ring and have a chat. You have my contact info.
