Generally speaking, vulnerability details have always been given to the vendor by responsible researchers free of charge. In exchange, vendors generally credit researchers with discovery or assistance. Often vendors will hire their own internal code audit teams instead of waiting for external security researchers to find bugs in their products. These people get paid, but they usually don't get credited for specific vulnerabilities.

The bottom line here is that no one is attempting to extort money out of vendors by holding a gun to their head and demanding payment. Computer Security problems are real, and vendors do need to address them, either by waiting for people to disclose bugs in their products or paying for proactive security analysis, but thats reality. There are a lot of bad people in the world who put a lot of effort into finding and exploiting 0day vulnerabilities in order to deploy spyware or commit various kinds of espionage. These people will find and exploit vulnerabilities in your product if internal audit or external researchers don't get to them first. Generally speaking, the later is a preferable scenario for everyone.

Now enter this company:

We can work with you to generate and enforce intellectual property such as patents relating to fixes for newly discovered, private or zero day security vulnerabilities, weaknesses, or technical flaws that you have found.

We target the intellectual property against the vendors of the vulnerable products and other security providers such as suppliers of intrusion prevention technologies.

You share in the income.

These people are saying: "I have a way to break into networks run by your customers through a bug in your product, and I'm going to publishing it to the world in the patent database, where any criminal can look it up and use it, but you can't fix it unless you pay me."

This seems very much like holding a gun to someone's head and demanding payment.

Whats even more insidious about this idea is that the patent holder has the right to refuse to license their patent at any price... A criminal organization could find a vulnerability, patent it, and use their patent to prevent their victims from fixing the problem.

I'd support legislation explicitly banning this practice.
