Patexia Contest




Patexia seeks prior art for US Patent 7,496,674 (‘674), with a focus on claims 1, 2, 4, 5, and 10. The patent allegedly describes a data packet transfer communication system with wired and wireless components, and a base station that bridges the two components of the network. The base station facilitates data packet transfers from the wired network to the wireless network, while maintaining one security protocol for the wired network, and a different security protocol for the wireless network.

The network contains 2 security protocols:

  1. for the wired portion of the network, a first security protocol (i.e., authentication and/or encryption) is applied to the data packet
  2. for the wireless portion of the network, the base station applies a second different security protocol employed by the wireless network

Any data packet transfer has the base station:

  • receive the data packet from the source via the wired network
  • process the data packet according to the first security protocol (e.g., decrypt data)
  • read the data packet’s header containing the address information of the destination device
  • apply the second security protocol (different from the one employed by the wired network)
  • wirelessly transmit the secured result to the destination

Have a question about this contest? Ask a Question


1Is the reference either a US patent filed, a foreign patent published, or a non-patent document published before July 9th, 1999? T/F
2Does the reference describe a data communication system where a base station facilitates a packet transfer from a source connected via a wired network, to a destination device connected via a wireless connection? 20
3Is the data packet received by the base station from the wired network subject to a security protocol such as authentication and/or encryption that has been performed on the data while on the wired network before arriving at the base station? 30
4Is the security protocol applied to the data while on the wired network compliant with the IPSec (internet protocol security) standard? 10
5Does the base station then determine the data packet’s destination via a header coded with the destination device’s address information? 5
6Does the base station then apply to the data packet a security protocol that is different from the security protocol applied while on the wired network and wirelessly transfer the secured result to the destination device? 35
