In this post I’m going to explain why patents can be a good idea, why they often go wrong today, and a way to fix that problem. And I’ll do that all in the context of a situation you should understand well: finding a shorter route to drive from home to work. (This post is ~1600 words, and so longer than usual.)
Imagine that you usually take a particular route from home to work, and some firm offers to find you a better route. You tell them your current route, and they tell you that they have found a different route that will save you thirty seconds a day, which over a year adds up to eight hours. You can inspect their route to verify their claim, but only if you agree that you can’t use that route (or anything close) unless you pay them a mutually agreeable fee. (Assume they can enforce that, by seeing your car’s driving path records. And assume you can verify their claim somehow.) You agree, inspect and verify, and then agree to pay them one hundred dollars, which is well below your value of saving eight hours of driving, and above their cost of finding the route.
This example contains an info property right: once you agree not to use their route unless you pay for it, then they own a right to your use of that route. Since the route is info, what they own is info. The prospect of owning that info right gives the firm an incentive to work to find that route. And because they must find a mutually agreeable price, their incentive to work is neither too much nor too little. An agreeable price must lie between their cost of finding the route and your added value from using it.
Now imagine that you are one of hundreds of drivers who go from the same initial home area to the same final work destination. Now this route-finding firm wants to sell a better route to all of you. But there is a problem. Once this firm sells the route to a few of of you, the others may learn of that route from these few buyers, either by being told or by following their cars. In this case the total price the firm could get from all the drivers might be much less than the sum of driver values for using the better route. Thus the firm’s incentive to work to find a better route could be too low. That is, this group of drivers could be better off it they joined together to paid the firm more to find a better route. But joining is too hard, so it doesn’t happen. Continue reading "Let Re-Discovery Evade Patents" »
