Vulnerability Patents

You wouldn’t normally want to dignify something like this, but it’s too interesting for me to pass up. Hat tip to Naraine for the headsup.

Intellectual Weapons is a “venture” that plans to solicit vulnerabilities from researchers so that the fixes can be patented and ransomed to vendors. Nice, huh?

Here’s why you shouldn’t care: it takes over 7 years (from the time you complete a filing) to have a patent issued. It takes many more years to initiate, litigate, and prevail in a patent claim, especially against an established software vendor. Presuming you do prevail; you likely won’t.

“Intellectual Weapons” has thought of this, of course: they’re not actually filing US Patents, which would be futile. Instead, your “intellectual property” will be enforced in venues that offer “utility models” (patents-lite), including various EU countries as well as places like Belarus and Tajikistan.

Would it be possibly for an outfit like “Intellectual Weapons”, exploiting the services of contingency-fee lawyers, to get an injunction against a Microsoft security fix in the Republic of Moldova? Anything’s possible. My money is on: this never happens. Not worth it, to anybody. The problem with international patents is that you have to fight them out jurisdiction-by-jurisdiction. In this case, you’d be slogging through those fights for a shot at a tiny sliver of the revenue generated by the products you’re targeting. This is nothing like NTP vs. RIM, where NTP’s claims enabled RIM’s entire product.

Here’s why you should care: “Intellectual Weapons” isn’t nearly first company to come up with this. Some companies have done this quite successfully, particularly with cryptography. You can absolutely patent a defense against an attack; if you discover the attack and patent every conceivable fix, and that attack is meaningful, you’ve got a very valuable piece of IP. By all means, if you break all known hash functions, or come up with a reliable remote side-channel attack that breaks TLS/SSL, patent away! 10 years from now, you might get a few tens of millions of dollars from it.
