Patexia Contest




Patexia is looking for descriptions for a USB peripheral device that can reconfigure itself based a configuration it downloads from a host computer without physically disconnecting the device.

Submitted documents describing this system must be:

  • filed or published before 07/02/1997
  • not on the known references list

The entire submission must describe a reconfiguration process with the following steps:

  1. USB peripheral device connects to a host computer using a default configuration
  2. USB peripheral device downloads a new configuration from the host computer
  3. USB peripheral device electronically simulates a disconnect/reconnect cycle without requiring a physical disconnect/reconnect
  4. USB peripheral device connects to the host computer using the new configuration

Figure 8. Flowchart showing the reconfiguration process.

This contest is for a prior art search for US Patent 6,249,825, with a focus on independent claims 1, 11, and 18, in addition to dependent claims 5, 6, 15, and 19.

Have a question about this contest? Ask a Question


1Is the reference either a US patent filed, US application published, a foreign patent published, or a non-patent document published before July 2nd, 1997? T/F
2Is the date that was submitted in question 1 before October 16th, 1996? 10
3Does the reference show a peripheral device that connects to a computer and when plugged in and operating switches from (a) an initial default configuration to (b) a different configuration? 25
4Does the reference show that after being connected using the (a) initial default configuration, the peripheral device has circuitry that downloads the (b) different configuration from the host computer? 20
5Does the reference show that when the switchover occurs, the peripheral device uses another circuit that electrically simulates a disconnect/reconnect cycle to allow the device to switch over to the new configuration? 25
6(4a) Does the reference further show that this electronic simulation is specifically designed to avoid requiring the user to physically disconnect and reconnect the peripheral device? 10
7Does the reference show that the peripheral device disconnects and reconnects to the host computer without cycling power on the peripheral device? 10
