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.
Prepare, prepare, prepare
A key to a successful interview involves preparation. Initially,
the practitioner must understand to the greatest extent possible,
the claimed invention, the examiner's rejections, and the prior
art cited against the claims.
