What Should be in a Patent Claim?
A patent claim is usually expressed as a statement of technical facts and legal terms. It defines the boundaries of an invention and lays down what the patent does and doesn’t cover. A claim should not be too broad or too narrow. It should include the minimal set of limitations that differentiate an invention over what came before it, i.e. the prior art. If you have more questions about this, you should consult with an experienced patent attorney.
