Abstract
An authentication method for authenticating an article in a device includes the steps of a) reading an identification number stored on the article, b) reading an authentication number stored on the article, c) determining an input number based at least in part on the identification number, d) applying an authentication function to the input number to calculate an output number, e) determining that the article is authentic only if the authentication number corresponds to the output number, and f) permitting use of the article in the device if the article is authentic, and disabling use of the article in the device if the article is not authentic.

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.
