Patent number 5,579,517, long file name support. MS-DOS before version 5 only supported 11-character file names (including extensions within
), so Microsoft invented a way to support both long and short file names. Friends who have used the DOS operating system should know that DOS will automatically shorten file names that exceed 11 characters and replace part of them with ~ symbols
. This patent is about this implementation. I am very confused, does the Android system use this patent? Patent No. 6,621,746, Flash memory erasure. Monitor flash memory usage and perform targeted erase operations when appropriate. This involves the management of the flash file system. The specific description is relatively complicated, so it is impossible to judge whether it is related to Android. Patent No. 6,909,910, Contact Creation and Update. Specifically, it is a system and method for updating a contact or creating a new contact from call records. Patent No. 7,644,376, system status monitoring and notification system. It is mainly about APIs that allow mobile applications to obtain phone status changes and manage global system status notifications. Patent No. 5,664,133, pop-up context menu system. The specific patent describes obtaining and displaying a series of commands in a pop-up menu for a user-selected object. This patent is probably Microsoft's dragon-slaying knife, which can kill gods when gods block it, and Buddha when it blocks Buddha. When Apple introduced the right-click menu, was it because of the Patent Cross-Licensing Agreement that Microsoft didn't sue? Patent No. 6,578,054, incremental synchronization. Systems and methods for synchronizing multiple copies of data between servers and clients, whereby incremental changes to one copy of the data are identified, transmitted, and integrated into all other copies of the data. According to this patent description, Android's data synchronization function can be said to be completely wiped out. Patent No. 6,370,566, initiates a scheduled meeting request from a mobile device. The implementation described in the patent is different from Google Calendar, so I don’t quite understand how this conflicts with Android.
