As part of an effort to update patent law, New Zealand legislators have proposed a bill which would make it impossible to patent software. If it becomes law it would no doubt cause friction with US ACTA negotiators, who are pushing to make software patents standard internationally.
Along with business processes, software has been the most controversial patent subject matter for several years. It's also behind much of the current smartphone patent war. If you own a phone with a touch screen, but not multi-touch, you can thank a software patent for it.
Other notable software patents include Amazon.com's infamous one-click patent for e-commerce websites and Netflix's patent on their queue system.
