Illumidine v. Fitly: SmartPlate Patent Suit Dismissed Without Prejudice in 129 Days
Illumidine, Inc. filed a patent infringement action against Fitly, Inc. in January 2024, asserting two patents covering the SmartPlate dining system and companion app. Before Fitly served any answer or dispositive motion, Illumidine voluntarily dismissed all claims — leaving the door open for future litigation.
SmartPlate patent claims dropped before Fitly ever filed a response
On January 23, 2024, Illumidine, Inc. filed an infringement action against Fitly, Inc. in the Texas Western District Court before Judge Robert Pitman, asserting US9782027B2 and US10085598B2 — two patents covering the SmartPlate dining system and its companion mobile application. The case was prosecuted by Rozier Hardt McDonough PLLC on behalf of Illumidine, with a four-attorney team including James F. McDonough, Jonathan L. Hardt, Jonathan R. Miller, and Travis E. Lynch.
On May 29, 2024 — just 129 days after filing — Illumidine filed a notice of voluntary dismissal without prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because Fitly had not yet served an answer or a motion for summary judgment, no court order was required: the dismissal was self-effectuating. Judge Pitman subsequently struck a Magistrate Judge order issued after the dismissal and formally closed the case on May 31, 2024.
The speed of the dismissal — before Fitly retained counsel of record or filed any responsive pleading — is notable and may suggest early settlement discussions, licensing negotiations, or a strategic reassessment of claim strength. Because the public record is silent on the reasons, none of these can be confirmed. Critically, a without-prejudice dismissal means Illumidine retains the right to refile infringement claims against Fitly on the same patents, subject to applicable statutes of limitations — making this a case to monitor.
Filing to Dismissed without Prejudice in 129 days
129 days — resolved before defendant filed any responsive pleading
Voluntarily dismissed: what the without-prejudice exit means for both parties
Rule 41(a)(1)(A)(i): self-effectuating voluntary dismissal
Federal Rule of Civil Procedure 41(a)(1)(A)(i) permits a plaintiff to dismiss an action unilaterally — without a court order — by filing a notice of dismissal before the defendant serves an answer or motion for summary judgment. Because Fitly had done neither, Illumidine’s notice was legally sufficient on its own to close the case. No judicial approval was required, and any subsequent court orders were properly struck.
No court order requiredDismissed without prejudice — but the public record explains nothing more
A dismissal without prejudice preserves the plaintiff’s right to refile. A dismissal with prejudice would bar future claims on the same patents against the same defendant. Illumidine’s notice expressly stated ‘without prejudice,’ meaning the door to future litigation on US9782027B2 and US10085598B2 against Fitly remains legally open. The public record does not disclose whether a private settlement, licence, or strategic decision drove the withdrawal.
Refiling rights preservedFitly exits without a merits ruling — but faces latent risk
Fitly, Inc. obtained no judgment on the merits, no invalidity ruling, and no finding of non-infringement. While the immediate litigation pressure has lifted, without-prejudice dismissal means Fitly cannot rely on res judicata to block a future action on the same patents. Companies in Fitly’s position should assess whether the underlying product features implicate the asserted claims, and consider design-around or licensing options proactively.
No res judicata protectionSmartPlate patents remain active enforcement tools
US9782027B2 and US10085598B2 emerge from this case entirely unscathed — no claim was invalidated, narrowed, or disclaimed. For competitors in the smart dining, food-tracking, and nutritional monitoring technology space, these patents should be treated as live enforcement risks. The Texas Western District Court remains a plaintiff-preferred venue, and Illumidine’s retention of refiling rights signals that these patents may be reasserted against Fitly or others.

Official order — verbatim text
The court’s closing order confirms that Illumidine’s Rule 41(a)(1)(A)(i) notice was self-effectuating — no judicial ruling on infringement, validity, or claim scope was issued. The explicit without-prejudice characterisation is legally significant: it preserves Illumidine’s standing to refile identical claims. The order striking the Magistrate Judge’s subsequent action reinforces the procedural precision of this mechanism — once the notice filed, the court lost jurisdiction to act further on the merits.
US9782027B2 & US10085598B2 — SmartPlate dining system patent portfolio
US9782027B2 (Application No. 15/387,410) and US10085598B2 (Application No. 15/672,114) both relate to the SmartPlate system — a technology platform that combines smart dinnerware hardware with a mobile application to enable automated portion analysis and nutritional tracking. The patents cover the integration of computer vision or sensor-based food identification with a connected app ecosystem, representing a technically differentiated approach to dietary monitoring beyond simple calorie-logging software.
These two patents form a small but potentially potent portfolio in the emerging smart dining and food-tech wearables-adjacent space. Neither patent faced any validity challenge, claim construction, or IPR institution through this litigation. For companies developing AI-assisted nutrition tracking, connected kitchen devices, or dietary monitoring platforms, the scope of these patents — unchallenged and intact — represents a meaningful enforcement risk, particularly given the patent holder’s apparent willingness to litigate in the Texas Western District Court.
Should you run an FTO against US9782027B2 and US10085598B2?
Product teams developing smart dinnerware, computer-vision dietary analysis tools, connected nutrition apps, or AI-powered portion tracking systems should treat these patents as active risks. Neither patent has been invalidated, disclaimed, or narrowed by any court. The Texas Western District Court filing confirms Illumidine’s enforcement posture, and the without-prejudice dismissal means these patents may be asserted again — against Fitly or against new market entrants — with no prior adverse ruling to rely on.

What this case signals for the smart dining technology IP landscape
A pre-answer voluntary dismissal rarely signals weakness alone — it often reflects commercial negotiation, claim reassessment, or strategic timing.
Without-prejudice dismissals are a litigation tactic, not a resolution
When a plaintiff withdraws before the defendant answers, it preserves maximum flexibility. Illumidine may be negotiating a licence, refining its claim mapping, or preparing to refile in a different venue or against additional defendants. Competitors and licensees in the smart dining space should not read this dismissal as an abandonment of enforcement intent.
Fitly’s lack of counsel on record may have influenced the timeline
No defendant agents or law firms appear in the public record for Fitly. This could suggest the company was unrepresented or in the process of retaining counsel when dismissal occurred. Early-stage pressure — before a defendant is fully mobilised — is a known strategy in patent litigation, particularly when the goal is rapid licensing rather than a merits victory.
Illumidine v Fitly — key questions answered
Illumidine, Inc. filed a patent infringement action against Fitly, Inc. on January 23, 2024 in the Texas Western District Court, asserting US9782027B2 and US10085598B2 covering the SmartPlate dining system. On May 29, 2024, Illumidine voluntarily dismissed all claims without prejudice under Rule 41(a)(1)(A)(i) before Fitly filed any answer or motion for summary judgment. The case was formally closed on May 31, 2024 after 129 days.
A dismissal without prejudice means Illumidine retains the legal right to refile infringement claims against Fitly on US9782027B2 and US10085598B2, subject to applicable statutes of limitations. The patents themselves are unaffected — no claim was invalidated, narrowed, or disclaimed. Fitly receives no res judicata or collateral estoppel protection from this outcome, leaving it potentially exposed to future litigation on the same patents.
Illumidine asserted two patents: US9782027B2 (Application No. 15/387,410) and US10085598B2 (Application No. 15/672,114). Both patents relate to the SmartPlate dining system and companion app, covering technology for automated portion analysis and nutritional tracking using connected dinnerware hardware integrated with a mobile application.
The public record does not disclose Illumidine’s reasons for dismissal. Common explanations in comparable cases include private licensing or settlement negotiations, strategic reassessment of claim infringement mapping, or a decision to refile in a different forum or against different defendants. The absence of any defendant counsel on the public record and the early stage of proceedings — before any responsive pleading — are consistent with, but do not confirm, any of these scenarios.
Yes. A voluntary dismissal without prejudice under Rule 41(a)(1)(A)(i) does not bar Illumidine from refiling infringement claims on US9782027B2 and US10085598B2 against Fitly. Fitly obtained no merits ruling, no invalidity finding, and no non-infringement determination. Future refiling would be subject to the six-year damages lookback under 35 U.S.C. § 286 and the applicable statute of limitations, but no procedural bar currently prevents a second action.
