The issue was not that Speedmaster copied the Broader transbrake, the issue is that the used the Broader Performance trademark on it, and not only is Speedmaster legally liable for trademark infringement but all their dealers are also liable. Summit and Jegs removed the product from their shelves to try and immunize themselves from and litigation. They basically told the world "we had no idea we were selling a counterfeit product, and as soon as we knew we removed the product from our site, destroyed the product, and removed the complete product line from our shelves". That way, if there is any litigation, they can claim that they knew nothing about it and they can place all the blame squarely on Speedmaster.
