Ah, you have hit the nail on the head. Yes, that would be foolish.Howver, absolutely nothing prevents you from telling people what you've done. That's actually how the engineering industry advances. Every single innovation is not a re-invention of something else. It's taking the work of someone before you, and making it cheaper, better performing, smaller, etc. Perfect example is Michelin, who in the consumer world at least, is the top tire manufacturer. They have openly stated throughout the years what their technologies are: dynamic tread blocks, new compound formulations, etc. This tells you NOTHING. It tells you where the industry is headed, and if you want to compete, you better get with it. Why does it tell you nothing? Because Michelin has simply shown you and told you the result.
The process to create such an innovation is the true secret. Without that, no one can replicate your results. This is why, if you look through Michelin's patent history, their patents are for novel methods and processes, not end results. Unless you can replicate the method, you'll never get their top end product. The same applies to tennis strings. Gamma told the world that they were using radiation to improve the life and playability of their tennis strings. That seems about as revealing as it can get. But how do you do it? Put some Moly99 (beta decay, but whatever) in your extrusion machine? Same applies to L-Tec.
Telling the world what they've done is called advancing the field. Keeping your trade secrets and patents close and your rival's' patents closer, you end up with innovation. You force people to improve on your result by telling them what you've done, and leave it up to them to make your product obsolete by either making the same thing in a simpler and thus cheaper way, or just making it better all around. Computer graphics cards are another excellent example of this. Single GPU cards are getting faster, but they're not getting hotter. That's how ATi and Nvidia can keep going at it while saying they're the top dog.
L-Tec has simply said you'll accelerate faster, brake shorter, corner at higher speeds, and get more longevity. They didn't bother telling us why or how.
