Report on Software Patents
sien writes: "The Fraunhofer Institute, holder of the patent on the MP3 codec, has published a report (PDF, German) recommending that patents on software not be added in the EU. There is a ZDNet story, and also here which is a German site for protecting innovation from misuse of patents. The report is important because it will be considered in the EU wide decision on software patents."
In this word sense, effect is the correct word -- effect is a noun, and affect is a verb. You affect to create an outcome, and that outcome is the effect.
Affect does have a noun form, however it relates to feelings, not causal constructs.
