Ideally, your patent attorney has an engineering background and hands-on experience patenting fitness and sporting goods products. It’s crucial that your attorney understand your invention thoroughly — every component and function — before you invest further in tooling, manufacturing, and marketing. The earlier we identify exactly what is novel and protectable about your invention, the sooner you can secure those rights and profit from them.
