There are other patents for their implementation, and all are filed in multiple countries. Look at the blue sidebar under "Worldwide applications".
The linked one is just for the US version of a singular patent. It had applications in 14 other countries and WIPO, 6 of which are still active (plus US).
Any seller of software would be liable for selling software to US customers without a patent license.
I'm curious about the legal consequences of freely distributed software (e.g. open source).
I wonder if the author/provider could be held liable if they:
- knowingly (passively) or actively market to US customers (e.g. provide support)
- are aware that US users are using it, and take no actions to prevent its distribution
etc.
Can someone share their knowledge on this?
If European software incidentally infringes a US patent, and it is distributed freely, is the provider then liable? E.g. is Github basically liable for restricting US users from access to (distributing) patent infringing software?
