NEW CANAAN, CT / ACCESS Newswire / September 10, 2025 / Network-1 Technologies, Inc. (NYSE:NTIP) announced today that its wholly-owned subsidiary, HFT Solutions, LLC ("HFT"), has initiated patent litigation against Optiver US LLC and Optiver Trading US LLC in the United States District Court for the Western District of Texas for infringement of U.S. Patent No. 10,931,286, U.S. Patent No. 11,128,305, and U.S. Patent No. 11,575,381 (collectively, the "Patents-in-Suit").

The Patents-in-Suit are part of the HFT patent portfolio acquired by HFT Solutions, LLC in March 2022 (the "HFT Patent Portfolio"). The HFT Patent Portfolio relates to, among other things, technologies used by firms engaged in high frequency trading activities that utilize field-programmable gate array (FPGA) hardware, including clock domain management technology that provides critical transaction latency gains in trading systems where the difference between success and failure may be measured in nanoseconds.

The HFT Patent Portfolio now includes eleven (11) issued U.S. patents and two (2) pending U.S. patent applications. The patent terms of the HFT Patent Portfolio are currently expected to extend until 2040. HFT Solutions anticipates further issuances of new claims for the HFT Patent Portfolio covering additional technologies contemplated by the patent applications.

The HFT Patent Portfolio is available for licensing to firms that make use of FPGA systems that utilize the HFT Solutions' patented technology to engage in low-latency high frequency trading as part of their market making activities in equities and derivative securities, or as part of their proprietary trading activities.
