I think this would make it tough to enforce the patent if it’s actually commonly used. If I were somehow granted a patent on tap dancing, its common usage by others before me would probably cause my patent to be invalidated if I then tried to sue a tap dancer.
Not a patent lawyer, but IIRC, US patent law had some protections for things (including non-patented) that are already common practice.
Software patents get away with stupid shit like this all the time. Patent trolls claim they invented a software pattern and then sue everyone who uses it.
You can’t grant a patent for something that is already in the public domain at the time of filing, regardless of whether or not that thing is currently patent protected.
Edit: this is such a funny comment to want to downvote. “Fuck you with your legitimate factual information!”
