I have a jacket with patches on it. They were, however, sewn on by the company that made the jacket for me. I supplied the patches. It was a custom measured and made jacket by Kushitani, in Japan. (their leather is thicker than what you get here in leather motorcycle jackets).
But for a jacket you really like that has no such work from the manufacturer, there are two options: get a place that has the machines and know how to sew leather, or do as KapKurt says and get a vest to wear over your jacket. Usually it is a denim vest at least for club badging purposes it is around here.
