MailBlocks sues Earthlink over Anti-Spam Tech 336

The only really big problem I can see is what happens if someone sends out spam with your email address. It seems like a potential DOS-style attack. It seems that there's an obvious solution to this: Add a standard string to be include in all response requests.

The fear is that (and rightly so), the patent office doesn't have the tech knowhow to decide a valid patent or not. Mailblock wants to patent "challenge and response" email. To me that is plain silly. The concept of a challenge and response has existed long before email in regards to communications. Applying such a broad concept to email is nothing new and is only a matter of who got there first.
What SHOULD happen is that a company is granted a valid patent on METHOD. At least in regards to software. Let's take Adobe. What if they were tto be granted a patent on ALL graphics designs programs? It would kill competition in it's tracks. Gimp? nope. PSP? nope. MSPAINT? probably but only because MS would pay the license fee.
You see, in terms of software, the traditional patent model does not work. There aren't enough new ideas out there. The concept of a drawing is as old as caves and berry juice. You can patent YOUR style of pen but not the concept of a pen. What happens is that companies patent more than just THIER way of doing something. Software patents in the current form are diametrically opposed to competition and freemarket operation.
The rules need to be rewritten to take into account this new model. Things like lifetime of a patent on software needs to be rethought as well as the whole process of granting the patent. In the software world, things move too fast. Patent lifetimes are NECCESARY to ensure non-stagnation.
Take the drug market. The patent on the drug (chemical makeup not concept) is the motivation for R&D. Patents encourage companies to develop something to make a profit by guaranteeing those companies the ability to have exclusive profit from that R&D. But this only goes so far. You've got only a few years before the patent expires and anyone else can make a generic version. They can't call it the same thing you do, but the can sure as hell color the pill the same as you.
What now for a company? They must reinvest the money earned from the short term exclusive right of patent and develop a better version. Or something new all together. The company that trys to live on one product dies a quick death. Ever wonder why there are so many versions of sudaphedrine? Patents FORCE innovation. The rules are simple. You come up with something new (such as a drug to inhibit HIV) and you get exclusive right to it. But only for a while. After so many years, anyone can produce it. It's now up to you (the company) to make a bigger and better HIV blocker. You know the rules. Everyone has to play by the same ones. Because a patent is public (has to be or else how would anyone know if they might infringe), you get that exclusivity= bonus for making it public. Don't like that rule? Keep it as a trade secret. The rules are different there. Much more difficult to enforce.
Almost done.
People also link patents to copyrights which have become a bastardized version of what they were. The current Micky Mouse is much better (to some) than the Steamboat Willy '46 version. Copyright terms forced Disney to make a better Mickey Mouse. The problem now (as we all know) is that Disney and the other large lobbies have decided that they don't want to play by the same rules that put them where they are. They are most undoubtedly an enemy of the freemarket and capitalism.
