I find it strange to see all the hate for BR over this patent. They patented the idea, they still make and sell the product. For once, we have a good invention (sliding on a sling) that is clearly superior in many ways to traditional fixed straps. I understand that there is some debate regarding prior art, but in this day and age, if you have an invention that you want to capitalize on, you have to protect it.
Is the BR the best implementation of a sling strap? Surely not, but as it stands, they own the idea. Luma and CS copied someone else's claimed invention and were taking market share from the inventors.
I find much less distasteful about this patent story than many of the software patents I read about every week, especially the troll companies who buy IP just to sue in El Paso, and have no other related business.
