The way patent law has developed means that there is a protected period, when market forces allow costs of an innovation to be recouped and profit made.

I just purchased a Surefire "Stlileto". I like Surefire as they are tough, bright, made in the USA and they are passionate about their products, which I always respect. I've never liked their clips and felt that their ergos could improve, but ergos are very difficult on a torch. The new model is very bright, a plus, and is rechargeable, another plus, and it offers multiple strengths, which is important for some. . It also has a much improved clip, which was lifted from my hourglass clip design which took me many years to refine to where it is now. I realize that designs refine, improve and evolve and I prefer the function of their new clip.
I'm not saying it's good or bad, it just is. I was curious as to what you thought about "lifting" designs from other companies?
When I first invented the pocket clip for knives, (1980) only 3 companies used the idea and paid us a royalty. Benchmade, Gerber and Cold Steel. Although virtually every knife company in the world has used or now offers a pocket clip on their knives.
