Once again, the patent system is being blatantly abused. A company is now patenting security patches (which could hardly be called inventive or innovative, because if most of a software company's innovation occurs in security patches, they have a serious problem).
They want researchers to go to them, disclose the vulnerability and the patch, and then they'll patent it and extort money from security vendors.
Once again, the purpose of patents is to encourage innovation and invention. If this is permitted and fast-tracked as Intellectual Weapons, the aptly named company, hopes, then vendors may start to avoid shipping security patches to avoid paying royalties.
So now vendors may have to pay to maintain their own products. The patent system is in desperate need of an overhaul in the United States.
