The accidental Singer sewing machine revolution - BBC News https://www.bbc.co.uk/news/business-50673541
Tenhle clanek ma v sobe zajimavej patentovej twist:
Singer patented his tweaks, and started to sell his version of the machine. It was impressive: the first design that really worked. You could make a shirt in just an hour.
Unfortunately, it also relied on various other innovations which had already been patented by other inventors - such as the grooved, eye-pointed needle, to make a lock stitch, and the mechanism for feeding the cloth.
During the so-called "sewing machine war" of the 1850s, rival manufacturers seemed to be more interested in suing each other for patent infringement than selling sewing machines.
Finally, a lawyer banged their heads together, pointing out that between them were four lots of people who owned patents to all the elements needed to make a good machine. Why not license each other, and work together to sue everyone else?
Freed from legal distractions, the sewing machine market took off - and Singer came to dominate it. That might have surprised anyone who had seen how his factories compared with those of his rivals.
