Brighton, CO asked in Patents (Intellectual Property) and Trademark

Q: I have a ramp from a pinball machine that was made by data east. The plastic ramp is broken.

I was looking to make another ramp or have one made and I don’t want to infringe on any patents. This plastic ramp has no mechanisms, no moving parts and is literally just a piece of plastic. There are mechanisms that attach to the ramp but I am not making any of those. Just the plastic ramp. Will I be infringing on any rights since they closed in 2003? I have looked over existing patents and trademarks and don’t see anything that would prevent me from doing it. Thank you

A: You should be OK as long as this piece is not special and does not have a patent just on that piece. A person that has purchased a patented item can make repairs. There is a limit and you cannot do such massive repairs to a totally worn out item that you are effectively replacing the original item. You do not sound anywhere close to that threshold.
