Cedar Lane Technologies v. Uhlmann Price Securities — Voluntarily Dismissed
Cedar Lane Technologies asserted US8577782B2 — covering trading with conditional offers for semi-anonymous participants — against Uhlmann Price Securities in the Northern District of Illinois. The plaintiff voluntarily dismissed the action after 142 days, before the defendant had answered the complaint.
Conditional-offer trading patent dismissed before Uhlmann Price answered
Cedar Lane Technologies, Inc. filed suit against Uhlmann Price Securities, LLC in the Northern District of Illinois (Case No. 1:25-cv-15329) on 17 December 2025, asserting infringement of US8577782B2. The patent relates to trading with conditional offers for semi-anonymous participants. The case was assigned to Judge Joan B. Gottschall. Cedar Lane was represented by Rabicoff Law LLC, while Uhlmann Price retained Faegre Drinker Biddle & Reath LLP.
The recorded basis of termination is Voluntary dismissal. The docket order states that, pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i), plaintiff dismissed the action with prejudice, noting that the defendant had not yet answered the complaint or moved for summary judgment, and that each party shall bear its own costs, expenses, and attorneys' fees. The specific terms underlying that decision are not disclosed in the available record.
The case closed on 8 May 2026, 142 days after filing — a timeline consistent with early-stage resolution before any substantive pleading exchange. What drove the plaintiff's decision to dismiss is not apparent from the public record, and no licensing agreement or settlement terms are disclosed.

US8577782B2 — trading with conditional offers for semi-anonymous participants


Any organisation developing, licensing, or operating electronic trading platforms that incorporate conditional-offer or semi-anonymous participant mechanisms should consider a formal freedom-to-operate analysis against US8577782B2. This is particularly relevant for broker-dealers, fintech startups, alternative trading systems, and dark-pool operators whose order-handling logic may overlap with the patent's claims. The dismissal of this case without any invalidity finding means the patent's claims are undiminished.
Official order — verbatim text
The docket order invokes Rule 41(a)(1)(A)(i), confirming the dismissal was made as of right before any responsive pleading, and states it is with prejudice with each side bearing its own costs. The order does not recite any claim construction, validity finding, or substantive adjudication. The specific terms and considerations driving the plaintiff's decision to dismiss are not disclosed in the available record.
Voluntarily dismissed: what the Rule 41 dismissal means for both parties
Rule 41(a)(1)(A)(i) dismissal — plaintiff's unilateral right before answer
Federal Rule of Civil Procedure 41(a)(1)(A)(i) permits a plaintiff to dismiss an action without a court order at any time before the opposing party has served an answer or a motion for summary judgment. The docket order confirms Uhlmann Price had not yet answered, making this a procedurally straightforward unilateral dismissal. The recorded basis of termination is Voluntary dismissal; the docket order itself states the dismissal is with prejudice.
Pre-answer voluntary dismissalWith prejudice vs. without prejudice — what the record says
The recorded basis of termination is Voluntary dismissal, without specifying prejudice. The docket order states the dismissal is with prejudice. A dismissal with prejudice is a final adjudication on the merits, barring Cedar Lane from re-filing the same claims against Uhlmann Price. A dismissal without prejudice would have preserved that option. The public record states the dismissal is with prejudice; beyond that, no further terms are disclosed.
Dismissal with prejudice per docket orderUhlmann Price exits before filing any substantive defence
Uhlmann Price Securities never filed an answer or dispositive motion. The cost-neutrality provision — each party bears its own fees — means Uhlmann Price recovers nothing in litigation costs despite retaining Faegre Drinker Biddle & Reath LLP. If the docket order's characterisation of with-prejudice dismissal holds, Uhlmann Price faces no further exposure to Cedar Lane on these specific claims. The specific terms underlying the resolution are not disclosed in the available record.
No answer filed; own costsUS8577782B2 remains in force — litigation exposure for the sector
A voluntary dismissal does not invalidate or limit the asserted patent. US8577782B2 remains an issued, enforceable patent. Other firms operating conditional-offer or semi-anonymous trading platforms should treat this dismissal as neutral to the patent's strength. Cedar Lane retains the right to assert this patent against other defendants. Market participants in electronic securities trading should consider the patent's claims in FTO analysis.
