Prior art

The USPTO Patent Public Search tool can be used to search for patent numbers. To search for a utility patent with six, seven, or eight digits, the number should be entered without commas or spaces, omitting leading zeros. For example, a 6-digit patent number like '123456' should be entered as '0123456' to make it 7 digits.

Regarding US patent 6920125, the following prior art was cited by the examiner:

• US6049543A:
  • Full Citation: US6049543A, Motorola, Inc., "Transcoder for use in an ATM-based communications system"
  • Publication Date: 2000-04-11
  • Filing Date: 1996-12-27
  • Brief Description: This patent describes a transcoder for an ATM-based communication system that converts speech from a mobile station into ATM cells. It aggregates multiple voice calls onto a single ATM virtual circuit to improve bandwidth utilization.
  • Potential Anticipation (35 U.S.C. § 102): US6049543A potentially anticipates claims related to aggregating or concatenating data packets for multiple users and transmitting them over a backhaul connection to improve efficiency. Specifically, elements of claims 1, 10, 15, and 36, which describe concatenating multiple data packets into an adaptation layer information packet for tunneling or transmitting over the backhaul connection, may be implicated.
• US6230012B1:
  • Full Citation: US6230012B1, Qualcomm Incorporated, "IP mobility support using proxy mobile node registration"
  • Publication Date: 2001-05-08
  • Filing Date: 1998-08-07
  • Brief Description: This patent details a method for providing IP mobility support using proxy mobile node registration, allowing mobile nodes to maintain connectivity while moving between different networks. It discusses tunneling techniques in the context of mobile IP.
  • Potential Anticipation (35 U.S.C. § 102): US6230012B1 potentially anticipates claims relating to tunneling information packets, particularly claims 1, 11, 15, and 37, which describe tunneling the adaptation layer information packet from the base station controller unit through the backhaul connection or adding an IP header to the adaptation layer information packet for tunneling.
• US6233458B1:
  • Full Citation: US6233458B1, Nokia Telecommunications Oy, "Re-routing procedure"
  • Publication Date: 2001-05-15
  • Filing Date: 1997-06-24
  • Brief Description: This patent focuses on a re-routing procedure in a cellular network, particularly for optimizing data transfer paths. While not explicitly about header compression or concatenation, it addresses efficient data handling in a mobile environment.
  • Potential Anticipation (35 U.S.C. § 102): Given its general focus on efficient data transfer paths in cellular networks, US6233458B1 might broadly relate to the underlying problem addressed by US6920125, but it doesn't appear to directly disclose the specific solutions of header reduction or concatenation. Thus, direct anticipation of specific claims regarding the IP Adaptation Layer is less likely, but it could be considered for broader concepts of optimizing communication in cellular networks.
• US6396828B1:
  • Full Citation: US6396828B1, Telefonaktiebolaget Lm Ericsson (Publ), "Arrangement system and method relating to data network access"
  • Publication Date: 2002-05-28
  • Filing Date: 1997-03-13
  • Brief Description: This patent describes a system and method for accessing a data network, particularly focusing on handling data connections and resource allocation. It addresses aspects of data communication efficiency in mobile networks.
  • Potential Anticipation (35 U.S.C. § 102): Similar to US6233458B1, this patent addresses general aspects of data communication efficiency and resource allocation in mobile networks. Direct anticipation of the specific IPAL protocol, header elimination, or data concatenation features of US6920125 is unlikely.
• US6701361B1:
  • Full Citation: US6701361B1, Intermec Ip Corp., "Enhanced mobility and address resolution in a wireless premises based network"
  • Publication Date: 2004-03-02
  • Filing Date: 1996-08-22
  • Brief Description: This patent describes methods for enhanced mobility and address resolution in wireless networks, enabling mobile devices to move seamlessly.
  • Potential Anticipation (35 U.S.C. § 102): This patent focuses on mobility and address resolution, which are different technical problems than the specific bandwidth optimization through header reduction and data concatenation taught by US6920125. Therefore, direct anticipation of claims in US6920125 is unlikely.
• US6751207B1:
  • Full Citation: US6751207B1, Cellco Partnership, "Tunnelling voice over the internet protocol in a cellular network"
  • Publication Date: 2004-06-15
  • Filing Date: 1999-07-27
  • Brief Description: This patent describes tunneling voice over IP (VoIP) in a cellular network. It deals with transmitting voice communications as IP packets and could involve mechanisms for efficient transport.
  • Potential Anticipation (35 U.S.C. § 102): US6751207B1 specifically mentions "tunneling voice over the internet protocol in a cellular network", which directly relates to the concept of tunneling voice-over-IP (VoIP) users that are a focus of US6920125 for small, frequently transmitted data packets. This patent could potentially anticipate claims 1, 3, 4, 11, 15, 17, 18, and 37, which refer to tunneling adaptation layer information packets and handling frequently transmitted data packets like those for VoIP users.
