Software patents
A patent is a 20 year monopoly on the use of an idea. In software, these monopolies cause many problems. Ideas must meet certain criteria in order for a patent to be given.

Definitions
A Software patent is a patent on an idea that can be implemented in software on a computer.
Put another way, it's a patent that can be infringed by writing or distributing software.
A patent on improving the braking of a car by configuring the car to use "anti-lock braking" would not be a software patent; it requires a car. On the other hand, someone writing a computer game involving cars would not be running any patent risk.
This includes patents on algorithms, file formats, and communication protocols. In a broad sense, it can include game patents, business methods, and network services.
For one attempt to describe this in a way suitable for legislation, see the EU 2005 proposed amendments.
To abolish software patents, we need to get software explicitly excluded from patentable subject matter.

Business methods
Business method patents are not necessarily software based, but I don't know of any patent that's been granted on a business method without a computer being included in the application.
