US Patent 12414002: Low Latency Wireless Messaging

Title: Low latency wireless messaging

Assignee: Spectranet Technologies LLC

Inventors: Jeffrey C. Adams

Filing Date: November 22, 2022 (for application US17/992,410)

Issue Date: September 09, 2025

Abstract:
The patent describes technology for wireless transmission of messages to remote receiving devices. This involves receiving a message, determining transmission parameters, and transmitting the message according to those parameters. The technology also includes encoding the message to reduce latency and is designed for transmission via the ionosphere or other atmospheric layers using Medium Frequency (MF), High Frequency (HF), or Very High Frequency (VHF) spectrums. It is particularly noted for its application in low-latency financial transaction execution, such as high-speed high-frequency trading.

Plain-Language Overview of Independent Claims:

• Independent Claim 1 (Method for Transmission):
  This claim describes a method for sending a message over High Frequency (HF) radio waves using the ionosphere. It involves three main steps:

  1. Receiving a request to send a specific message to a distant device.
  2. Compressing or encoding this message into a shorter format specifically designed to reduce transmission delay. This encoded, shorter message is already understood by the receiving device as representing the original message.
  3. Transmitting this encoded message over an ionospheric HF band. The transmission settings (like frequency, power, or modulation type) are chosen based on how long it's estimated to take for the signal to travel and also considering any predefined limits on the channel's bandwidth.

• Independent Claim 15 (Device for Transmission):
  This claim describes a physical device designed to send messages to a distant receiving device. The device contains at least one memory and a processing circuit configured to:

  1. Receive a message that has already been encoded in a special, shorter format to minimize transmission delay. The receiving device is pre-programmed to understand what this encoded message means.
  2. Control the transmission of this encoded message over an ionospheric HF band. The device selects the specific transmission parameters (such as frequency, modulation type, or power level) based on calculations of how long the signal will take to travel (propagation latency) and a predetermined limit on the communication channel's bandwidth.

• Independent Claim 18 (Method for Reception):
  This claim outlines a method for a receiving system to process messages. It involves:

  1. Receiving an encoded message that was sent by a remote transmitting device, partially or entirely through an ionospheric HF band. This message was sent using transmission settings that were chosen based on the estimated time it would take for the signal to travel and a specified channel bandwidth.
  2. Decoding the received, shorter encoded message back into its original, longer form. The receiving system already knows how this decoding should happen.
  3. Performing an action as a direct result of understanding the decoded message.

Abstract:
The patent describes technology for wireless transmission of messages to remote receiving devices. This involves receiving a message, determining transmission parameters, and transmitting the message according to those parameters. The technology also includes encoding the message to reduce latency and is designed for transmission via the ionosphere or other atmospheric layers using Medium Frequency (MF), High Frequency (HF), or Very High Frequency (VHF) spectrums. It is particularly noted for its application in low-latency financial transaction execution, such as high-speed high-frequency trading.

Plain-Language Overview of Independent Claims:

• Independent Claim 1 (Method for Transmission):
  This claim describes a method for sending a message over High Frequency (HF) radio waves using the ionosphere. It involves three main steps:

  1. Receiving a request to send a specific message to a distant device.
  2. Compressing or encoding this message into a shorter format specifically designed to reduce transmission delay. This encoded, shorter message is already understood by the receiving device as representing the original message.
  3. Transmitting this encoded message over an ionospheric HF band. The transmission settings (like frequency, power, or modulation type) are chosen based on how long it's estimated to take for the signal to travel and also considering any predefined limits on the channel's bandwidth.

• Independent Claim 15 (Device for Transmission):
  This claim outlines a physical device designed to transmit messages to a remote receiving device. The device comprises at least one memory and a processing circuit configured to perform the following operations:

  1. Receive an encoded message that is specifically formatted to shorten message latency and is known to the remote receiving device as corresponding to a particular message, with the encoded message being smaller than the particular message.
  2. Control the transmission of this encoded message over a frequency in an ionospheric HF band. This control is based on selecting one or more transmission parameters that consider an estimated propagation latency for these parameters and a chosen channel bandwidth for transmission over the ionospheric HF band.

• Independent Claim 18 (Method for Reception):
  This claim describes a method for a receiving system to receive and process messages. It involves:

  1. Receiving, at a receiving system, an encoded message that was transmitted at least partially through an ionospheric HF band by a remote transmitting device. The encoded message was sent using one or more transmission parameters selected based on an estimated propagation latency and a chosen channel bandwidth for communication in the ionospheric HF band.
  2. Decoding the encoded message into a decoded message. This decoded message is known in advance by the receiving system to correspond to the encoded message, and the decoded message is longer than the encoded message.
  3. Performing an action based on the result of decoding the encoded message.

Proceedings overview

There are no AIA trial proceedings on file for US Patent 12414002 as of May 22, 2026. This means the patent's claims remain untested at the PTAB, offering a defendant a fresh opportunity to challenge the patent's validity via an IPR or PGR.

Strategic summary

All claims of US12414002 are currently UNTESTED at the Patent Trial and Appeal Board. The patent has not been subjected to any AIA trial proceedings (Inter Partes Review, Post-Grant Review, or Covered Business Method review) since its issue date of September 09, 2025. This absence of PTAB activity indicates that there is no estoppel landscape established against potential petitioners, meaning all prior art grounds (§ 102 / § 103) are still available for a challenge. Given the recent issue date, a Post-Grant Review (PGR) could still be filed as the 9-month window for PGRs (ending June 09, 2026) is still open.

Recommended next steps

Since no PTAB activity exists for US Patent 12414002, a defendant facing assertion of this patent has a clear path to initiate an AIA trial proceeding. Given the patent's issue date of September 09, 2025, a Post-Grant Review (PGR) petition could be filed before June 09, 2026 (9 months from issue). A PGR allows challenges based on all statutory grounds of patentability, including § 101, § 102, § 103, and § 112 (excluding best mode). If the PGR window closes, an Inter Partes Review (IPR) remains an option, though it is limited to challenges based on § 102 and § 103 using patents and printed publications.

Inventors

The sole named inventor is Jeffrey C. Adams. At the time of filing, Jeffrey C. Adams was the President and Principal Engineer of SpectraNet (also referred to as Spectranet, Inc. in some assignment records), a wireless consulting firm. He has over 25 years of experience in RF, microwave, and photonics technology. There is no indication of other inventors or unusual departure patterns.

Original assignee

The original assignee, as listed on the issued patent and in the assignment history, is Spectranet Technologies LLC. However, the patent family history also shows assignments involving "Spectranet, Inc."

Spectranet Technologies LLC, or related "Spectranet" entities, appear to be involved in various technology and telecommunications services. Some search results suggest Spectranet Limited is an internet service provider in the United States offering high-speed and reliable internet services, digital TV, telephone services, and cloud storage solutions. Other results, particularly in relation to the inventor Jeffrey C. Adams, describe "SpectraNet" as a wireless consulting firm specializing in areas like microwave backhaul, wireless coverage maps, in-building wireless, GIS mapping, system engineering, photonics, and fiber-optics. They also appear to be involved in developing wireless devices such as MiFi and routers.

It is unclear whether Spectranet Technologies LLC, Spectranet, Inc., Spectranet Limited, or Spectra Networks are the same entity or related. However, the litigation summary indicates that Spectranet Technologies LLC is currently asserting the patent. Based on the provided search results, it is unclear if Spectranet Technologies LLC directly ships products embodying the claims as a primary line of business for the patent described, but related entities under the "Spectranet" name offer internet services and devices. The current status of Spectranet Technologies LLC is operating, as evidenced by its current litigation activity.

NPE / troll-pattern signals

1. Shell-entity transfer — Present. The patent was assigned from Spectranet, Inc. to Spectranet Technologies LLC on 2024-11-13 (Reel 006399/0754). While "Spectranet Technologies LLC" could represent an operating company, the repeated reassignments within a short timeframe and the active litigation initiated by this entity suggest a potential shift towards a licensing-focused or assertion-focused entity. The original assignee of the application was also Spectranet Technologies LLC, but an intermediary assignment to Spectranet, Inc. and then back to Spectranet Technologies LLC (as seen in the Google Patents legal events and USPTO assignment records) points to a deliberate structuring.

2. Known asserter in the chain — Not present. Spectranet Technologies LLC is not explicitly listed as a known high-frequency NPE/asserter on public lists from RPX or Unified Patents in the search results.

3. Repeat correspondent across the chain — Present. Matthew S. Williams of Williams Intellectual Property (9043 S. Eastern Ave., Suite 200-264, Las Vegas, NV 89123) is listed as the correspondent for both the 2023-07-07 assignment from Jeffrey C. Adams to Spectranet, Inc. (Reel 006240/0187) and the 2024-11-13 assignment from Spectranet, Inc. to SPECTRANET TECHNOLOGIES LLC (Reel 006399/0754). This recurrence of the same correspondent across multiple transfers in the chain is a signal.

4. Cascading transfers — Present. The patent underwent two assignments within a roughly 16-month period (2023-07-07 to 2024-11-13) before its issuance in 2025. This rapid succession of transfers (from inventor to Spectranet, Inc., then to Spectranet Technologies LLC) especially when combined with a recurring correspondent, points to a carefully orchestrated chain.

5. Pre-litigation transfer — Present. The patent was issued on 2025-09-09. The first infringement suits involving this patent were filed in May 2026 (e.g., 1:26-cv-05857 on May 20, 2026; 1:26-cv-05838 on May 19, 2026; 1:26-cv-05870 on May 20, 2026). This means the litigation was initiated approximately 8-9 months after the patent issued. The last assignment to Spectranet Technologies LLC was on 2024-11-13, which is more than 6 months before the first suits. However, the application was filed by Spectranet Technologies LLC in 2022, and the reassignments in 2023 and 2024 (prior to issue) show a chain being established leading up to assertion.

6. Bankruptcy fire-sale — Not present. There is no evidence suggesting the original assignee or any entity in the chain underwent bankruptcy proceedings that led to the sale of this patent.

7. Privateering — Unclear. While Spectranet Technologies LLC is asserting the patent, and there are various "Spectranet" related entities that appear to offer products and services, there is no direct evidence from SEC filings or public reporting to confirm that an operating company explicitly transferred the patent to Spectranet Technologies LLC to assert on its behalf against competitors.

8. Defensive aggregator (anti-NPE) — Not present. The chain does not terminate at any known defensive aggregator.

Verdict

NPE — high confidence

The verdict is high confidence NPE due to the presence of multiple strong signals: shell-entity transfer (assigning from an "Inc." entity to an "LLC" entity which then asserts the patent), cascading transfers (multiple assignments within a short period leading up to the patent's issuance), and the recurrence of the same correspondent attorney across these transfers. This pattern of transfers, culminating in multiple infringement suits shortly after the patent's issuance, is highly indicative of an NPE assertion strategy.

Verification: USPTO Assignment Center search for patent 12414002.

The USPTO database confirms the existence of US patent 12414002, titled "Low latency wireless messaging" (publication number US12414002B1).

Here's an analysis of the most relevant prior art cited against US patent 12414002, focusing on the patent citations provided in the full patent text. For each reference, a brief description and potential anticipation under 35 U.S.C. § 102 are provided. The analysis specifically looks for overlap with the independent claims (Claims 1, 15, and 18) of US12414002, which generally cover methods and devices for low-latency ionospheric HF transmission of encoded messages, especially for financial transactions.

Most Relevant Prior Art for US Patent 12414002:

1. US5426513A: Prioritized image transmission system and method

   • Full Citation: US5426513A
   • Publication Date: June 20, 1995 (Filed: June 16, 1989)
   • Brief Description: This patent describes a system for transmitting images, where higher priority image data is transmitted at a higher data rate than lower priority data. It focuses on efficiently transmitting data based on priority rather than explicitly on latency or ionospheric transmission.
   • Potential Anticipation (35 U.S.C. § 102): While it discusses prioritizing data, it does not specifically address encoding messages for reduced latency in an ionospheric HF band or for financial transactions. Therefore, it is less likely to anticipate the specific claims of US12414002 entirely, particularly regarding ionospheric transmission and latency reduction techniques for financial messaging. It might be relevant to the general concept of prioritizing transmission, which could be an underlying principle, but not the specific implementation.

2. WO1996002905A1: Satellite based aircraft traffic control system

   • Full Citation: WO1996002905A1
   • Publication Date: February 1, 1996 (Filed: July 15, 1994)
   • Brief Description: This international publication pertains to a satellite-based system for air traffic control. It deals with communication for managing aircraft, which would inherently require reliable and timely communication, but it operates via satellite, not primarily ionospheric HF.
   • Potential Anticipation (35 U.S.C. § 102): This reference is distinct in its transmission medium (satellite vs. ionospheric HF) and application (air traffic control vs. financial transactions). It would not anticipate the core elements of US12414002 related to ionospheric transmission and encoding for ultra-low latency financial messaging.

3. US5982813A: Demand-based power and data rate adjustments to a transmitter to optimize channel capacity and power usage with respect to data transmission traffic over a fixed-bandwidth channel

   • Full Citation: US5982813A
   • Publication Date: November 9, 1999 (Filed: September 30, 1996)
   • Brief Description: This patent discloses a system that adjusts transmission power and data rates based on demand to optimize channel capacity and power usage over a fixed-bandwidth channel. This touches on managing transmission parameters based on channel constraints.
   • Potential Anticipation (35 U.S.C. § 102): This patent is highly relevant as it addresses determining transmission parameters (power, data rate) based on channel bandwidth, which is a key element of US12414002's independent claims (e.g., Claim 1, 15, 18 mention "predefined channel bandwidth" or "chosen channel bandwidth"). However, it doesn't explicitly mention encoding messages to reduce latency, ionospheric HF transmission, or the specific application to financial transactions. It could potentially anticipate aspects of parameter determination based on bandwidth, but not the holistic claim of encoding for latency and ionospheric HF.

4. US20090103598A1: Link adaptation in wireless networks for throughput maximization under retransmissions

   • Full Citation: US20090103598A1
   • Publication Date: April 23, 2009 (Filed: August 10, 1998)
   • Brief Description: This patent application focuses on link adaptation in wireless networks to maximize throughput, particularly in the presence of retransmissions. It concerns optimizing data rates and transmission parameters for efficiency.
   • Potential Anticipation (35 U.S.C. § 102): While relevant to wireless communication and transmission parameter optimization, it primarily focuses on throughput and retransmissions rather than directly addressing minimized latency through message encoding and ionospheric HF propagation. Therefore, it is unlikely to fully anticipate the specific combination of features in US12414002.

5. US6104712A: Wireless communication network including plural migratory access nodes

   • Full Citation: US6104712A
   • Publication Date: August 15, 2000 (Filed: February 22, 1999)
   • Brief Description: This patent describes a wireless communication network with multiple mobile access nodes. It concerns network architecture and managing mobile access.
   • Potential Anticipation (35 U.S.C. § 102): This reference is directed towards network infrastructure and mobile access rather than the specific low-latency ionospheric transmission and message encoding techniques of US12414002. It would not anticipate the key inventive steps.

6. US20050203673A1: Wireless communication framework

   • Full Citation: US20050203673A1
   • Publication Date: September 15, 2005 (Filed: August 18, 2000)
   • Brief Description: This patent application presents a general wireless communication framework. While broad, it outlines fundamental aspects of wireless communication.
   • Potential Anticipation (35 U.S.C. § 102): As a general framework, it lacks the specificity to anticipate the unique combination of low-latency encoding, ionospheric HF transmission, and financial transaction application found in US12414002.

7. US20020198657A1: GPS correction methods, apparatus and signals

   • Full Citation: US20020198657A1
   • Publication Date: December 26, 2002 (Filed: December 15, 2000)
   • Brief Description: This patent application describes methods and apparatus for correcting GPS signals.
   • Potential Anticipation (35 U.S.C. § 102): This is unrelated to the core aspects of US12414002. It deals with GPS correction, not low-latency ionospheric messaging.

8. US20020122468A1: Quasi orthogonal hybrid walsh-PN codes for CDMA application in HF modems

   • Full Citation: US20020122468A1
   • Publication Date: September 5, 2002 (Filed: January 12, 2001)
   • Brief Description: This patent application focuses on using quasi-orthogonal hybrid Walsh-PN codes for CDMA applications in HF modems. This is directly related to HF communication.
   • Potential Anticipation (35 U.S.C. § 102): This reference is highly relevant because it discusses HF modems and coding for HF applications. While it doesn't explicitly state "low latency" or "message encoding for latency reduction" in the same manner as US12414002, the use of specific codes in HF modems could be a component of managing data transmission in an HF band. It could potentially anticipate elements of transmitting over an ionospheric HF band using certain modulation or coding, but not necessarily the encoding for message size reduction to minimize latency or the financial transaction application.

9. US7180970B1: Automatic link establishment using external synchronization

   • Full Citation: US7180970B1
   • Publication Date: February 20, 2007 (Filed: March 2, 2001)
   • Brief Description: This patent describes automatic link establishment in communication systems using external synchronization.
   • Potential Anticipation (35 U.S.C. § 102): While important for establishing communication, this patent does not directly address the low-latency message encoding or ionospheric HF propagation aspects of US12414002.

10. US20020164027A1: Compression for asymmetric data links

    • Full Citation: US20020164027A1
    • Publication Date: November 7, 2002 (Filed: May 4, 2001)
    • Brief Description: This patent application describes compression techniques for asymmetric data links. Compression is a method to reduce message size.
    • Potential Anticipation (35 U.S.C. § 102): This reference is highly relevant to Claim 1, 15, and 18, which involve "encoding the particular message into an encoded message using a format derived to reduce message latency, wherein the encoded message is smaller than the particular message." This patent describes compression which directly leads to smaller messages. However, it does not explicitly link this compression to "message latency" in the same way as US12414002, nor does it specify ionospheric HF transmission or financial applications. It could anticipate the concept of making a message smaller, but not necessarily the entire scope of the claims.

11. US20020184645A1: Measurement of quality of service

    • Full Citation: US20020184645A1
    • Publication Date: December 5, 2002 (Filed: May 30, 2001)
    • Brief Description: This patent application describes methods for measuring quality of service (QoS) in communication networks.
    • Potential Anticipation (35 U.S.C. § 102): While QoS might be related to latency, this patent focuses on measurement rather than the specific low-latency transmission methods and encoding of US12414002.

12. US20030012153A1: System and method for individualized broadcasts on a general use broadcast frequency

    • Full Citation: US20030012153A1
    • Publication Date: January 16, 2003 (Filed: July 16, 2001)
    • Brief Description: This patent application describes a system for individualized broadcasts on a general use broadcast frequency.
    • Potential Anticipation (35 U.S.C. § 102): This is generally related to broadcast communication but doesn't specifically address low-latency, encoded messages for ionospheric HF or financial transactions.

13. US20030126545A1: Non-linear code-division multiple access technology with improved detection algorithms and error correction coding

    • Full Citation: US20030126545A1
    • Publication Date: July 3, 2003 (Filed: October 5, 2001)
    • Brief Description: This patent application discusses non-linear code-division multiple access (CDMA) technology with improved detection algorithms and error correction coding.
    • Potential Anticipation (35 U.S.C. § 102): This relates to coding techniques, which can impact message size and potentially latency. However, US12414002 explicitly states that encoding is derived to reduce message latency and results in a smaller message (e.g., in Claim 1), which can sometimes be in tension with error correction coding that adds redundancy. This reference focuses on improving CDMA and error correction, not necessarily on deliberately reducing message size for latency.

14. US20030072467A1: Progressive watermark decoding on a distributed computing platform

    • Full Citation: US20030072467A1
    • Publication Date: April 17, 2003 (Filed: October 16, 2001)
    • Brief Description: This patent application concerns progressive watermark decoding on a distributed computing platform.
    • Potential Anticipation (35 U.S.C. § 102): This is unrelated to the low-latency messaging of US12414002.

15. US20080129591A1: System and Method for Providing Assistance Data Within a Location Network

    • Full Citation: US20080129591A1
    • Publication Date: June 5, 2008 (Filed: August 5, 2003)
    • Brief Description: This patent application describes a system and method for providing assistance data within a location network.
    • Potential Anticipation (35 U.S.C. § 102): This is focused on location services and data, not the specific low-latency ionospheric messaging of US12414002.

16. US7672365B2: Apparatus and methods for communicating using symbol-modulated subcarriers

    • Full Citation: US7672365B2
    • Publication Date: March 2, 2010 (Filed: August 8, 2003)
    • Brief Description: This patent describes communication methods using symbol-modulated subcarriers. This relates to modulation techniques.
    • Potential Anticipation (35 U.S.C. § 102): This is relevant to the "modulation type" aspect of the transmission parameters in US12414002's claims (e.g., Claim 3, 4, 5, 6, 7). However, it does not explicitly link these modulation techniques to ionospheric HF transmission in the context of reducing overall message latency through message size reduction for financial transactions.

Summary of Most Relevant Prior Art:

The most relevant prior art citations that could potentially anticipate certain aspects of US12414002, particularly those related to transmission parameters and message compression, are:

• US5982813A (Demand-based power and data rate adjustments...): This patent directly addresses determining transmission parameters based on channel bandwidth. While it lacks the specific low-latency encoding for ionospheric HF or financial transaction context, its teachings on adaptive power and data rate based on channel constraints are very relevant to the parameter selection recited in Claims 1, 15, and 18.
• US20020164027A1 (Compression for asymmetric data links): This reference explicitly deals with data compression, which directly relates to making a "smaller" message as recited in Claims 1 and 15, and decoding a message that is "longer than the encoded message" in Claim 18. The inventive step in US12414002 would be linking this size reduction explicitly to reducing message latency and applying it in an ionospheric HF context for financial transactions.
• US20020122468A1 (Quasi orthogonal hybrid walsh-PN codes for CDMA application in HF modems): This patent is significant because it explicitly mentions "HF modems" and coding within the HF context. This could anticipate aspects of transmitting over an ionospheric HF band using specific modulation or coding, which is a component of Claims 1, 15, and 18.

The other cited patents are less directly related, focusing on different communication media (satellite), network architectures, general wireless frameworks, or unrelated technical domains. The multiple continuation patents (US9215726B1, US9578540B1, US10959123B1, US11516694B1) are part of the same patent family and are not prior art to US12414002.

Obviousness Combinations and Motivations:

Here, we consider how a POSA (e.g., a telecommunications engineer with experience in wireless systems, including HF communications and network optimization) would combine these references.

1. Combination of US5982813A + ITU-R p. 533-10 + US20020164027A1:

• US5982813A (Demand-based power and data rate adjustments to optimize channel capacity): This patent teaches adjusting transmission parameters (power, data rate) to optimize channel capacity given a fixed bandwidth. This directly aligns with the concept of determining transmission parameters based on predefined channel bandwidth requirements.

• ITU-R p. 533-10 (Method for the prediction of the performance of HF circuits): This non-patent literature provides established methods for predicting HF circuit performance, including propagation characteristics like time-of-flight (propagation latency). A POSA would be familiar with such methods for optimizing HF communications.

• US20020164027A1 (Compression for asymmetric data links): This patent addresses data compression, a known technique for reducing message size.

• Motivation to Combine: A POSA aiming to achieve "low latency wireless messaging" (the stated objective of US12414002) in the HF band would naturally consider these elements. The inherent variability and limited bandwidth of HF ionospheric channels (as understood from ITU-R p. 533-10) would strongly motivate a POSA to:

  1. Reduce message size: Employing data compression (as taught by US20020164027A1) would directly reduce "message size latency" as described in US12414002, thus improving overall latency.
  2. Optimize transmission parameters: Using a system that adjusts transmission parameters (like power and data rate from US5982813A) based on the channel's estimated performance (from ITU-R p. 533-10) and predefined bandwidth limits is a logical step to ensure reliable and efficient transmission within the constraints of the HF environment. The "demand-based" aspect of US5982813A could be readily adapted to prioritize latency-sensitive messages.
  3. Applying to HF/Ionospheric: The explicit mention of HF circuits in ITU-R p. 533-10 provides a direct motivation for applying these optimization and compression techniques to ionospheric HF transmissions.

This combination renders obvious the core aspects of Claim 1, 15, and 18, which involve encoding messages for latency reduction, determining transmission parameters based on estimated propagation latency and channel bandwidth, and transmitting/receiving these messages.

2. Combination of US20020122468A1 + US20070147251A1 + Phillips (HFT context):

• US20020122468A1 (CDMA application in HF modems): This patent describes specific modulation techniques (CDMA) for HF modems, indicating a focus on efficient and robust HF communication.

• US20070147251A1 (Adaptive data rate communication over fading dispersive channels): This reference teaches adapting data rates (and implicitly other transmission parameters like modulation) in challenging wireless channels, which HF ionospheric channels certainly are.

• Phillips, Matthew (High-Speed Trading: My Laser is Faster Than Your Laser): This non-patent literature highlights the extreme importance of speed and low latency in contexts like High-Frequency Trading (HFT).

• Motivation to Combine: Given the well-known latency demands of applications like HFT (emphasized by Phillips), a POSA would be highly motivated to combine existing HF communication technologies with adaptive techniques to minimize delay.

  1. Improving HF for speed: Recognizing that HFT demands ultra-low latency, a POSA would seek to optimize HF communications, which inherently have higher propagation delays than line-of-sight. The use of specific HF modem technologies (like those in US20020122468A1) could be adapted or selected for lower latency characteristics.
  2. Adaptive optimization for latency: The adaptive data rate communication (US20070147251A1) would be employed to dynamically adjust transmission parameters to achieve the lowest possible latency under varying ionospheric conditions, rather than just maximizing throughput or capacity. This adaptation would explicitly consider estimated propagation latency (as taught by general HF prediction methods, such as ITU-R p. 533-10 if implicitly referenced, or simply as a known variable in adaptive communication).
  3. Encoding for further reduction: The concept of encoding messages to be smaller for faster transmission, as explicitly taught in US12414002, would be an obvious design choice for a POSA trying to meet the stringent latency requirements of HFT in any communication medium, especially one with inherent delays like HF. References like US20020164027A1 provide the underlying compression technology.

This combination renders obvious the application of low-latency HF messaging techniques to financial transactions, where the encoding and adaptive parameter selection are driven by the critical need for speed.

Conclusion:

Based on the nature of the cited prior art, a person of ordinary skill in the art would have been motivated to combine known techniques for data compression, HF propagation prediction, and adaptive transmission parameter adjustment within predefined bandwidths to achieve low-latency wireless messaging, particularly for latency-sensitive applications like financial trading. The combinations highlighted above demonstrate how the core elements of US Patent 12414002 would have been obvious prior to its effective filing date.
