Letters of this nature can be deceptively short and should neither be sent, nor result in a response, without a careful balancing of the rights involved, the competitive or business relationship between the parties, the result asked, also encompassing a tone of threat or compromise. Poorly thought out cease and desist letters have yielded unwanted results.
