Abstract
An electronic publication publishing and distribution system is provided for dissemination of written materials that can be read on a portable electronic book. A host computer contains an inventory of written materials in electronic form, that can be selected and then downloaded into the portable electronic book's memory. The host computer keeps track of the transactions, and encodes the data prior to downloading, using an encryption system involving a security number that is unique to the portable electronic book. The encrypted data cannot be decrypted until it is resident in the memory of the portable electronic book. Upon receipt of the encrypted data, the portable electronic book decrypts the data, and can display the text of the original material on its display screen. The portable electronic book has a central processing unit with an operating system for controlling the functions of the portable electronic book. There is non-volatile electronic memory storage for retaining publications in the portable electronic book. A plurality of electronic keys is provided in the portable electronic book that corresponds to graphical representations such as icons on the portable electronic book display adjacent to each key. These keys are integral to the user interface for controlling the devices.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
