The US Patent Office has revealed a number of recent patent filings by Apple.
The first notable filing deals with automatic shutdown of a device and/or host after certain conditions are met, such as after a portable media player's battery is finished charging, or after a file transfer is complete. Apple suggests a scenario where an iPod or iPhone is plugged into an iMac to charge, but the user wishes for both to go to sleep or shutdown after the charge is complete (which may take several hours). The application, #20070294546, initially filed June 19, 2006 was made public today.
The other filing of note, patent application #20070288886, deals with attempts to fight software piracy.
A digital rights management system permits an application owner to cause code to be injected into the application's run-time instruction stream so as to restrict execution of that application to specific hardware platforms. In a first phase, an authorizing entity (e.g., an application owner or platform manufacturer) authorizes one or more applications to execute on a given hardware platform. Later, during application run-time, code is injected that performs periodic checks are made to determine if the application continues to run on the previously authorized hardware platform. If a periodic check fails, at least part of the application's execution string is terminated--effectively rendering the application non-usable. The periodic check is transparent to the user and difficult to circumvent.
Apple has thus-far resisted industry trends towards activation of software, and currently only uses such methods in some of its most costly professional software. While it is clear that Apple has been working on methods to combat piracy, it remains to be seen how far Apple will employ the methods in its software. Readers are reminded that only a portion of the applications filed end up making it to shipping products.
