If these patents are still active, can they be used outside of country. For example, if I live in the USA, can I use a similar patent (cap pierced)? Or would I still face patent infringement?
I tried looking everywhere to see where it says it's officially filed or if it was expired. I see dates and codes but I have trouble understanding what they mean, even after searching them up. I just want to see if it would be safe and not worry about committing infringement.
I would really appreciate if someone can clarify this for me! I'm scared of getting sued!
Thank you so much!
