The US Patent and Trademark Office has approved a patent filed by Apple, which prevents users from sending or receiving "objectionable" text messages. In one embodiment, the control application includes a parental control application. The parental control application evaluates whether or not the communication contains approved text based on, for example, objective ratings criteria or a user's age or grade level, and, if unauthorized, prevents such text from being included in the text-based communication. If the control contains unauthorized text, the control application may alert the user, the administrator or other designated individuals of the presence of such text. The control application may require the user to replace the unauthorized text or may automatically delete the text or the entire communication.
