Independent claims
What is actually asserted, verbatim.
1. A method for ionospheric Radio Frequency (RF) transmission of a message in a High Frequency (HF) band to a remote receiving device, the method comprising: receiving a request to transmit a particular message to the remote receiving device; encoding the particular message using a format derived to effect message latency into an encoded message for transmission on a frequency in an ionospheric HF frequency band, wherein the encoded message is known a priori to the remote receiving device as corresponding to the particular message, and wherein the encoded message is smaller than the particular message; determining transmission parameters for transmission of the encoded message in the ionospheric HF frequency band based at least on (a) message latency and on (b) a predefined channel bandwidth; and transmitting the encoded message over the frequency in the ionospheric HF frequency band using the determined transmission parameters.
8. A device for transmitting messages to a remote receiving device, the device comprising: at least one memory and at least one processing circuit, wherein the at least one memory and the at least one processing circuit are respectively configured to store and execute instructions for causing the device to perform operations for transmitting the messages to the remote receiving device, the operations comprising: encoding a particular message using a format derived to effect message latency into an encoded message for transmission on a frequency in an ionospheric High Frequency (HF) frequency band, wherein the encoded message is known to the remote receiving device as corresponding to the particular message, and wherein the encoded message is smaller than the particular message; determining transmission parameters for wireless transmission of the encoded message to the remote receiving device based at least on (a) message latency and on (b) a predefined channel bandwidth; controlling transmission of the encoded message over the frequency in the ionospheric HF frequency band based at least on the determined transmission parameters.
13. A device, comprising: at least one memory and at least one processing circuit, wherein the at least one memory and the at least one processing circuit are respectively configured to store and execute instructions for causing the device to perform operations for transmitting messages to a recipient device, the operations comprising: receiving an encoded message configured to convey a particular message to the recipient device, the encoded message having a format derived to effect message latency when transmitted on a frequency in an ionospheric HF frequency band, wherein the encoded message is known to the recipient device as corresponding to the particular message, and, wherein the encoded message is smaller than the particular message; determining transmission parameters for transmission of the encoded message in the ionospheric HF frequency band based at least on (a) message latency and on (b) a predefined channel bandwidth; and transmitting the encoded message over the frequency in the ionospheric HF frequency band using the determined transmission parameters.

Abstract
Technology for wireless transmission of messages to remote receiving devices is disclosed. The technology includes receiving a message for transmission, determining transmission parameters for transmission of the message, and transmitting the message to a remote receiving device according to the determined transmission parameters. The technology may also include encoding the message to effect message latency and may be employed for message transmission via the ionosphere or other atmospheric layer at frequencies in the Medium Frequency (MF), High Frequency (HF), or Very High Frequency (VHF) spectrum. Further, the disclosed technology may be employed for message transmission to effect low latency financial transaction execution, such as high speed high frequency trading.

Named in one of these suits? A prior-art search is commissioned once and serves every defendant who shares it. The examiner's own search record is free on the tools page, and your first preliminary search is free — one claim, back within 24 hours — so you know whether there is art the Office never saw before anyone pays for more. Flat fees: $2,500$899 for the independent claims, $5,000$1,500 for every asserted claim.
This page is assembled from public records — federal court dockets and the patent's own file — and is updated as the case list changes. It states what the record shows and is not an opinion on the validity or infringement of any claim. Patent data via Google Patents; docket data via CourtListener.
