Examiners do not have much time to search and act on a single application. In addition, often the subject matter is highly complex. An interview can be an ideal teaching opportunity with charts, tables, pictures, and other means of disseminating and summarizing information. It can help show why the claims are allowable. Such presentations can prevent prosecution from bogging down completely. If a new examiner is assigned to your case, a summary presentation may be an ideal way to bring them up to speed with an efficiency that they will appreciate.
