Just because I don't have enough understanding in other fields outside of software. It is possible, for example, that medicine today requires patents to advance faster.
Edit (to answer biehl's comment): I meant abolish "software" patents.
(Edit: Then your statement still makes no sense. If you understand that he spoke only about software patents - why do you then needlessly broaden the subject?)
Edit2: It is worse-than-useless to demand no action for softwarepatents until all patent types have been analyzed. Do you also support stabbing people being legal until all uses of knives (in kitchens etc.) have been analyzed? Or do you see that we can reasonably outlaw some form of knife-use?
