"Jason Haislmaier claimed, instead, that software patents don't really create entrepreneurship; people invent because that is who they are. And he noted that software patents are especially useless for startup companies. It can currently take something like seven years to get a patent; by that time, the company has probably been sold (or gone out of business) and the inventors are long gone. Jason Mendelson, who does a lot of venture capital work, had an even stronger view, using words like "worthless" and "net negative." He claimed that startups are frequently sued for patent infringement for the simple purpose of putting them out of business."
