A method of unlocking at least one feature of a diagnostic device. The method includes receiving, from a user, product-indentifying information (such as serial number) for the diagnostic device. A server can then generate a software key that corresponds to the product-identifying information and transmit the software key to the user via a text-to-speech server to cause the software key to be spoken to the user. The user can enter the software key into the diagnostic device to unlock the at least on feature. The transaction can be initiated at the user's telephone where the software key is also , received eliminating the need for a network-connected diagnostic device.

Why it's free to use
- Filed June 27, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 27, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 27, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
