I just found out that there is a similar apparatus to what I developed made by XYZ Company called the XYZ Company Widget. It doesn’t look anything like my invention, though. The main component of each device is a spring (I assume this because the XYZ Company product moves like it has a spring inside it).

How do I know if the patent for the XYZ Company Widget protects it against my invention? Thank you for any information you can provide.
