Freedom of expression

Software patents can interfere with people's freedom of expression in two ways.

Communication technology

Most modern communication technology is based on software. If only MyCompany can use a certain communication technology, then anyone who can't afford the software of MyCompany, or anyone who objects to using the software of MyCompany is excluded from certain types of communication.

For example: How many patents are violated by swpats.org?

Discussing technology

If something is patented, then you might not be able to publish an article about it.
