M$ sued over software patents and Salesforce is retaliating over software patents, showing how utterly useless these things are for promoting innovation. Read Mary Jo Foley’s take on this.
Perusing the list of things M$ says were infringed include the who’s who of computer science 101. I teach data structures to high school students and they obtain patents on these things because the USPTO is full of people who never took that course.
M$ is a patent-troll and it is time someone stood up to them.
