Bataan Licensing v. Hydraforce: Voluntary Dismissal After 134 Days
Bataan Licensing LLC asserted US7423982B2, covering adaptive communication modes, against Hydraforce Inc. in the Northern District of Illinois. The case closed in under five months when Bataan filed a voluntary dismissal under Rule 41(a)(1) — before Hydraforce had served an answer or summary judgment motion.
Adaptive comms patent dropped before Hydraforce filed an answer
On 27 September 2022, Bataan Licensing LLC filed a patent infringement action against Hydraforce Inc. in the U.S. District Court for the Northern District of Illinois, Case No. 1:22-cv-05248, before Judge Andrea R. Wood. The sole patent asserted was US7423982B2 (application number US10/237299), directed to adaptive communication modes. Hydraforce Inc., a manufacturer of hydraulic and electrohydraulic components, was named as the sole defendant.
The recorded Basis of Termination is 'Voluntary dismissal.' The docket order states that Bataan filed a Notice of Voluntary Dismissal with Prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1), citing that no answer or motion for summary judgment had been served by Hydraforce. The case closed on 8 February 2023. The specific terms underlying the dismissal are not disclosed in the available public record.
The 134-day duration — from filing to closure — is notably brief, suggesting resolution occurred well before any substantive motion practice or claim construction. What drove the decision to dismiss at this early stage is not apparent from the public record, and no licensing terms or settlement agreement are disclosed. The case generated no judicial rulings on the merits of the asserted patent.

US7423982B2 — Adaptive Communication Modes
Any R&D or product team building systems that dynamically switch, manage, or adapt communication modes — whether in industrial controllers, IIoT devices, embedded wireless modules, or hydraulic control systems — should consider a formal freedom-to-operate review against US7423982B2. The patent has never been ruled invalid or not infringed, and the dismissal in this case provides no legal protection to third parties. The plaintiff's licensing-entity structure suggests continued assertion activity is possible.
Official order — verbatim text
The docket records Bataan's filing of a Notice of Voluntary Dismissal with Prejudice under Rule 41(a)(1), which operates without court order when filed before the defendant serves an answer or motion for summary judgment. No judicial finding was made on infringement, validity, or any substantive issue; the case closed on procedural termination alone.
Voluntary dismissal: what the early exit means for both parties
Rule 41(a)(1): plaintiff-initiated exit before responsive pleading
Under Federal Rule of Civil Procedure 41(a)(1), a plaintiff may dismiss an action without a court order by filing a notice of dismissal before the defendant serves an answer or a motion for summary judgment. Bataan invoked this rule, meaning the dismissal required no judicial approval and was self-executing upon filing. This mechanism is available only in the early pre-answer window.
Pre-answer dismissalWith or without prejudice? The public record distinction matters
The Basis of Termination recorded in the docket is 'Voluntary dismissal' without specifying prejudice. The docket order separately states the dismissal was filed 'with prejudice.' These two characterisations are reported as-is; the public record does not reconcile them. A dismissal with prejudice bars the plaintiff from re-filing the same claims against the same defendant; one without prejudice does not. The operative legal effect depends on which characterisation governs.
Prejudice status not conclusively settled in recordBataan exits without a merits ruling on US7423982B2
Bataan Licensing obtained no judicial finding of infringement, validity, or enforceability. The patent's legal status is unaffected by the dismissal itself — US7423982B2 remains in the public record as an issued patent. Whether Bataan retains the ability to assert it against other parties is not affected by this dismissal on its face, though the prejudice qualifier (if operative) forecloses further action against Hydraforce.
No merits adjudicationHydraforce avoids merits exposure with no ruling on validity
Hydraforce achieved dismissal without filing an answer, incurring the cost of full litigation, or obtaining a ruling of non-infringement or invalidity. The absence of a merits ruling means Hydraforce did not secure a formal finding that could be used offensively in future disputes. The commercial terms of any resolution, if any exist, are not disclosed in the public record.

R&D signals in the adaptive communications IP space
Forward-looking patent and innovation intelligence derived from Bataan Licensing's assertion of US7423982B2 against Hydraforce in the adaptive communications technology domain.
Bataan Licensing's assertion footprint beyond this case
Bataan Licensing's filing of US7423982B2 against an industrial hardware maker suggests a broader licensing campaign that may extend across multiple technology segments. Reviewing Bataan's full assertion history and related patent holdings can reveal which adjacent product categories — embedded wireless, fieldbus, or IIoT communication stacks — face the highest residual risk.
NPE portfolio riskFiling trends in adaptive communication mode patents
The adaptive communication modes space — covering dynamic protocol selection, mode switching, and parameter adaptation — is an active filing area driven by IIoT, 5G, and embedded systems growth. Tracking recent grant and publication trends in this domain helps R&D teams identify crowded claim areas, white space for new filings, and potential blocking positions held by competitors or NPEs.
Active filing domainHydraforce's IP position in electrohydraulic communication systems
Hydraforce develops electrohydraulic components increasingly integrated with digital communication interfaces. Assessing Hydraforce's own patent portfolio in communication-enabled hydraulic control reveals whether the company is building defensive IP in this space and how its technology development compares with the claims asserted by Bataan in US7423982B2.
Electrohydraulic comms IPAdjacent claim space around adaptive mode selection in industrial hardware
The intersection of adaptive communication mode management and industrial hardware control — particularly in hydraulic, pneumatic, and motion control systems — remains a relatively sparse patent filing zone compared with consumer wireless. R&D teams developing smart actuator communication layers or multi-protocol industrial gateways may find protectable white space adjacent to the claims of US7423982B2.

What this case signals for the adaptive communications IP landscape
An early voluntary dismissal against an industrial defendant raises questions about claim scope, licensing strategy, and the enforceability posture of adaptive communications patents.
Pre-answer dismissals are a key signal in NPE litigation patterns
When a non-practising entity voluntarily dismisses before a defendant answers, it often signals one of three scenarios: a resolution was reached off-record, claim mapping against the specific defendant proved difficult, or litigation economics shifted. Teams monitoring NPE activity around adaptive communications protocols should track Bataan Licensing's filing history across other defendants for pattern evidence.
US7423982B2 remains live and unlitigated on the merits
No court has ruled on the validity or infringement scope of US7423982B2. For product teams working on adaptive communication mode switching — including industrial IoT, hydraulic control systems, or multi-mode wireless — this patent warrants a formal FTO review. The dismissal provides no safe harbour against future assertions by Bataan or any successor in interest.
Bataan v Hydraforce — key questions answered
Bataan Licensing LLC filed a patent infringement action against Hydraforce Inc. in the Northern District of Illinois on 27 September 2022, asserting US7423982B2 covering adaptive communication modes. The case closed on 8 February 2023 — 134 days later — when Bataan filed a notice of voluntary dismissal under Rule 41(a)(1). No substantive rulings were issued. The specific terms of any resolution are not disclosed in the public record.
US7423982B2 (application US10/237299) is directed to adaptive communication modes — broadly, systems or methods that dynamically adjust or select communication protocols or parameters in response to operating conditions. Bataan asserted this patent against Hydraforce, a manufacturer of hydraulic and electrohydraulic control components, in an infringement action. No court has ruled on the patent's validity or the scope of its claims.
The recorded Basis of Termination in the docket is 'Voluntary dismissal' without specifying prejudice. The docket order separately states that Bataan filed a Notice of Voluntary Dismissal 'with prejudice' pursuant to Rule 41(a)(1). These two characterisations are reported as-is from the public record; the page does not reconcile them. The specific operative legal effect depends on which characterisation governs in the record.
No. A voluntary dismissal under Rule 41(a)(1) does not constitute a merits adjudication. No court ruled on whether US7423982B2 is valid, infringed, or enforceable. The patent remains a granted U.S. utility patent and is not rendered invalid or unenforceable by this dismissal. Third parties cannot rely on the dismissal as a safe harbour against future assertions of US7423982B2.
Because no court has ruled on the validity or infringement scope of US7423982B2, the patent remains an active assertion risk for any product incorporating adaptive communication mode selection or switching logic. Product teams in industrial IoT, embedded wireless, hydraulic control, or multi-protocol systems should consider a formal FTO review against the patent's claims. The dismissal against Hydraforce provides no legal protection to other parties.
