Most Relevant Prior Art for US Patent 12414002:

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.
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.
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

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

- 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.
US7180970B1: Automatic link establishment using external synchronization

- 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.
US20020184645A1: Measurement of quality of service

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

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.
