software patents in switzerland

The institute of computer science at the University of Zurich has developed a new software (TeNDaX) which allows more than 300 people to work on one text-document simultaneously. As you can read here (German) the university will file a patent application.
I’m surprised, does software patents already exists in switzerland?

Beside the problem of software patents it’s sad that a university, financed by the society, uses their research results that way. The task of a university should be research for the benefit of the whole society and not for the disadvantage of the society. I think there should be a law that all research results, financed by the society, should be released into the public domain or licensed under something like the modified BSD license.
