HFT Solutions, LLC v. Citadel Securities LLC

Summary

The United States District Court for the Northern District of Illinois denied Citadel Securities LLC's Rule 12(b)(6) motion to dismiss patent-infringement claims brought by HFT Solutions, LLC. The court held that, at the pleading stage, HFT's asserted claims concerning FPGA systems and phase-locked-loop clock synchronization were not shown to be directed to an abstract idea and, alternatively, plausibly recited an inventive concept under 35 U.S.C. § 101.

Holdings

1. Claim 1 of each asserted patent may be treated as representative of the respective patent's remaining claims for the eligibility analysis because the remaining claims depend on or relate back to claim 1, and HFT did not identify a claim limitation with distinctive significance that would materially affect the eligibility inquiry.
2. The asserted claims are not directed to the abstract idea of synchronizing data processing with a clock; instead, they are directed to a specific technological improvement to FPGA architecture and methods for reducing latency through a specified arrangement of components.
3. Even if the asserted claims were directed to an abstract idea, the complaint and patent allegations plausibly established an inventive concept in the nonconventional arrangement of components, and factual disputes concerning whether the claimed combination was well-understood, routine, and conventional precluded dismissal under Rule 12(b)(6).

Questions Presented

1. Whether claim 1 of each asserted patent could properly be treated as representative of the remaining claims for purposes of the § 101 eligibility analysis.
2. Whether the asserted patent claims were directed to an abstract idea under the first step of the Alice framework.
3. Whether, alternatively, the asserted claims recited an inventive concept under the second step of the Alice framework and could be found patent-ineligible on a Rule 12(b)(6) motion.

Disposition
