Excluding software from patentability
There are two main approaches on how to write a law banning software patents. The most commonly discussed approach is to exclude software from patentability, which means that patent offices cannot not grant software patents and courts cannot uphold them if they are granted. This can be implemented by new legislation or by a senior court interpreting existing legislation as excluding software from patentable subject matter.
The other approach is shielding software from litigation.
