Problem

Patexia seeks prior art for US Patent 6,131,032 (‘032), with a focus on claim 17. The patent allegedly describes a system for maintaining lawful intercept lists by receiving lawful intercept information into a master intercept list stored on a central register, and then disbursing that information to switches within the network, which store the information in a local intercept list..

When a law enforcement agency serves a warrant for a wiretap on an individual to a telephone service operator, there is a need to maintain a central database of lawful targets to ensure that only lawfully targeted citizens are subject to a wiretap, and that these individuals are dutifully removed once the legal order expires. However, the nature of a telephone service network is that calls are handled by local switches throughout a decentralized network, not through one central location; a problem further exacerbated with satellite communication systems that can spread the network even further such that it covers many different legal jurisdictions and involves multiple independent law enforcement agencies.

The patent allegedly describes a system that allows centralized administration and management of the far-flung intercept lists by:

  • receiving intercept information into a master list that is stored and maintained on a central register or “monitoring location register”
  • distributing the intercept information from the central register out to local switches where each switch includes a local intercept list
