Since e-mail is currently unsecure, when your correspondence relates to applications
for patents which are not yet laid open, you may wish to indicate that future
correspondence should be sent by regular mail, to provide better security for the
information being transmitted. Please advise us if you change your e-mail
address so that all future correspondence can be sent to you in a timely manner.
We encourage you to read the additional "Help" information available when you are
filling in the form. If you want to familiarize yourself with the various aspects of
a patent application and its preparation please go to the tutorial on how to write a
