The statement that there is support for software patents from business is a lie.
While a few large companies do support software patents because they have a lot of them and because their position on software patents is drafted by their patent lawyers (and no their actual management).
However overwhelming majority of IT related businesses and also all non-IT businesses that have looked into the issue are opposed to software patents.
I personally know that because I argued the anti-software patent stance to the Latvian IT association against a few well versed Microsoft lobbyists and in the end all key members of the IT association (except MS) voted to send a strongly worded anti-software patent message to EU Parliament and to Latvian government on behalf of Latvian IT industry.
We have seen the same situation all across EU - a few large players were in favor of software patents and where there was no opposition and no information they just wrote 'industry opinions', but in the cases where both arguments were brought forward and where there was an actual discussion IT community strongly rejected software patents.
In many cases when an association expressed support of software patents it was later discovered that members of these associations not only were not asked of their opinion, they did not even know that their association provided such a position in their name.
