US Patent 9686193: Filtering Network Data Transfers

• Title: Filtering network data transfers
• Current Assignee: Centripetal Networks LLC
• Inventor: Sean Moore
• Filing Date: February 18, 2015 (for application US14/625,486, of which this patent is a continuation)
• Issue Date: June 20, 2017
• Abstract: The patent describes methods for filtering network data transfers. It involves receiving multiple packets and determining if a portion of these packets has header field values that correspond to a specific packet filtering rule. If so, an operator defined by that rule is applied to that portion of packets. A further step involves determining if one or more of these packets have application header field values matching criteria specified by the operator. If this match occurs, a packet transformation function specified by the operator is applied to those packets.

Plain-Language Overview of Independent Claims:

• Claim 1 (Method): This claim describes a method performed by a computing system to filter packets from a first network. If a group of packets is identified as being intended for a second network and matches rules designed to block a specific type of data transfer, then these packets are dropped. Conversely, if another group of packets does not match these blocking criteria and is intended for a third network, they are forwarded to the third network, bypassing the blocking rules.
• Claim 8 (Method): This claim focuses on filtering packets containing eXtensible Messaging and Presence Protocol (XMPP) data. If an XMPP packet matches criteria set by rules to prevent a particular type of data transfer from a first network to a second network, that packet is dropped. If another packet does not contain XMPP data, it is forwarded towards the second network, without applying the XMPP-specific blocking rules.
• Claim 18 (System): This claim outlines a system (including a processor and memory) configured to perform the method described in Claim 1. The system receives packets, identifies those matching criteria for a prohibited data transfer to a second network (and drops them), and identifies those not matching the criteria for a prohibited data transfer destined for a third network (and forwards them).
• Claim 19 (Computer-readable Media): This claim covers non-transitory computer-readable media storing instructions that, when executed by one or more computing devices, cause them to perform the method described in Claim 1. This includes receiving packets, applying a dropping operator to a portion matching specific criteria for a blocked data transfer to a second network, and applying a forwarding operator to a portion not matching those criteria for transfer to a third network.

Litigation Information:

Based on the provided patent data, US9686193 is actively involved in litigation. Specifically, there are records of cases filed in the Virginia Eastern District Court and the Court of Appeals for the Federal Circuit (CAFC).

Regarding CAFC dockets for 2026, the patent listing indicates:

• A US case filed in the Court of Appeals for the Federal Circuit (case/24-2097)
• A US case filed in the Court of Appeals for the Federal Circuit (case/21-1888)

While the patent itself lists these CAFC cases, it does not explicitly state their current status in 2026. Further detailed docket searching would be required to determine if these specific cases are active in 2026 or if new CAFC cases related to this patent have been filed in 2026.A concise summary of US patent 9686193 is provided below, along with details regarding its litigation status.

US Patent 9686193: Filtering Network Data Transfers

• Title: Filtering network data transfers
• Current Assignee: Centripetal Networks LLC
• Inventor: Sean Moore
• Filing Date: February 18, 2015 (Application number US14/625,486)
• Issue Date: June 20, 2017
• Abstract: The patent describes a method for filtering network data transfers. This involves receiving multiple packets, identifying a portion of these packets with header field values that correspond to a specific packet filtering rule, and then applying an operator defined by that rule to those packets. A further step involves determining if one or more of these packets have application header field values that match criteria specified by the operator. If such a match occurs, a packet transformation function specified by the operator is applied to those packets.

Plain-Language Overview of Independent Claims:

1. Claim 1 (Method): This method involves a computing system receiving packets from a first network. If a "first portion" of these packets is detected to be destined for a second network and matches criteria within packet-filtering rules designed to prevent a specific type of data transfer, then a first operator is applied to drop these packets. Conversely, if a "second portion" of packets does not match these blocking criteria and is destined for a third network, a second operator is applied to forward these packets towards the third network, explicitly without applying the rules configured to prevent the particular type of data transfer.
2. Claim 8 (Method): This method also involves a computing system receiving packets from a first network. It specifically addresses packets related to the eXtensible Messaging and Presence Protocol (XMPP). If a "first packet" contains XMPP data that matches criteria in packet-filtering rules configured to prevent a particular type of data transfer to a second network, then a first operator is applied to drop this first packet. If a "second packet" does not contain data associated with XMPP, a second operator is applied to forward this second packet toward the second network, without applying the rules designed to prevent the particular type of data transfer.
3. Claim 18 (System): This claim describes a system, comprising at least one processor and memory storing instructions, configured to perform the method outlined in Claim 1. The system is designed to receive packets, determine if a first portion meets criteria for a prohibited data transfer from a first network to a second network (and consequently drop them), and determine if a second portion does not meet these criteria for a prohibited data transfer to a third network (and consequently forward them, without applying the blocking rules).
4. Claim 19 (Computer-readable Media): This claim covers one or more non-transitory computer-readable media containing instructions. When executed by one or more computing devices, these instructions cause the devices to perform the method of Claim 1. This includes receiving packets, identifying a first portion that matches criteria specified by packet-filtering rules for preventing a particular type of data transfer from a first network to a second network (and dropping them), and identifying a second portion that does not match these criteria for transfer to a third network (and forwarding them, without applying the blocking rules).

Litigation Status:

US Patent 9686193 is currently marked as "Active" and has a history of litigation.

According to the provided patent information, litigation related to this patent family has been filed in:

• The Virginia Eastern District Court (e.g., cases 1:22-cv-00001, 2:22-cv-00002, 2:18-cv-00094).
• The Court of Appeals for the Federal Circuit (CAFC) (e.g., cases 24-2097, 21-1888).

There are also records of PTAB cases (IPR2021-01520 and IPR2018-01559), both of which were not instituted.

Regarding CAFC dockets specifically for 2026, the patent record lists case 24-2097, which commenced in 2024 and could potentially still be active or have had developments in 2026. Case 21-1888, from 2021, may also have ongoing relevance. The provided information indicates the existence of these cases but does not confirm their active status specifically within the 2026 calendar year.
