Mellaconic IP v. Deputy, Inc. — Time Clock App Patent Case Closes After 1,303 Days
Mellaconic IP, LLC asserted US9986435B2 against Deputy, Inc.’s Time Clock App in the District of Delaware, alleging patent infringement. The case ran for over three and a half years before closing in November 2025, with the basis of termination recorded as ‘Other’ — leaving the precise resolution terms absent from the public docket.
A long-running Delaware patent dispute over workforce time-tracking IP
Mellaconic IP, LLC filed suit against Deputy, Inc. on April 27, 2022, in the U.S. District Court for the District of Delaware before Judge Colm F. Connolly. The sole patent asserted was US9986435B2 (application no. US14/885515), covering technology related to mobile time-clock and workforce-management applications. The accused product was Deputy’s Time Clock App, a scheduling and attendance-tracking tool used across shift-based industries.
The case was marked closed on November 20, 2025, with the docket entry reading ‘CASE CLOSED’ and the basis of termination recorded simply as ‘Other.’ This designation is notably non-specific: it does not confirm a settlement, a voluntary dismissal, a judgment on the merits, or a transfer. The public record is therefore silent on whether a financial resolution was reached or whether the case ended on procedural grounds.
At 1,303 days, the litigation ran for well over three years — a duration consistent with a case that progressed through claim construction, discovery, and potentially dispositive motion practice before resolution. The absence of a trial-level verdict or explicit settlement notice suggests the matter likely resolved quietly, possibly through a confidential agreement. No defendant law firm is recorded on the public docket, which may indicate Deputy managed portions of the litigation in-house or that representation details were not fully captured at filing.

Case closed under ‘Other’ basis: what the docket record reveals
‘Other’ termination: a non-standard closure designation
When a federal district court records a basis of termination as ‘Other,’ it signals the case ended outside the standard procedural categories — such as voluntary dismissal, consent judgment, or trial verdict. This designation is sometimes used when parties reach a confidential resolution that is not formally memorialised as a settlement on the public docket, or when an administrative closure follows a lapse in activity. The precise legal mechanism here is not publicly determinable.
Resolution mechanism unclearMellaconic IP: enforcement outcome uncertain from public record
As a non-practising entity asserting a single patent, Mellaconic IP’s objective was likely to extract a licensing fee or damages from Deputy. Whether that goal was achieved is unknown. The ‘Other’ termination basis means there is no public judgment, consent decree, or settlement notice confirming any payment. Absent a recorded adverse judgment, the patent US9986435B2 is presumed valid and potentially available for further enforcement against third parties.
Outcome not publicly confirmedDeputy, Inc.: no public adverse finding recorded
Deputy faces no publicly recorded finding of infringement or damages award. The case closing without a trial verdict or entered judgment is consistent with a negotiated exit. However, without confirmation of a licence or dismissal with prejudice, it cannot be confirmed that Deputy has fully extinguished its exposure under US9986435B2. Companies in the workforce-management software space monitoring this case should note the absence of any claim invalidity ruling.
No infringement finding on recordTime-clock software IP: enforcement risk remains live
The closure without a public merits ruling means US9986435B2 has not been adjudicated as valid, invalid, infringed, or not infringed. This leaves the patent’s enforceability status unchanged from a third-party perspective. Workforce-management and time-tracking app developers should treat this patent as an active enforcement risk until a USPTO reexamination, IPR, or subsequent court ruling provides a definitive validity determination.

Official order — verbatim text
The docket entry ‘CASE CLOSED’ with basis of termination recorded as ‘Other’ provides no merits-level disposition. There is no claim construction ruling, no summary judgment outcome, and no trial verdict in the public record. This phrasing is administratively neutral — it confirms the court has closed the matter but does not adjudicate the underlying infringement or validity questions raised by Mellaconic IP’s assertion of US9986435B2 against Deputy’s Time Clock App.
US9986435B2 — Mobile time-clock and workforce attendance technology
US9986435B2 (application US14/885515) covers technology in the mobile workforce-management space, specifically relating to time-clock functionality delivered via app-based platforms. The application number indicates a filing in the US14/8xxxxx series, consistent with applications filed in the mid-2010s — a period of rapid expansion in cloud-based HR and scheduling software. The patent’s B2 designation confirms it issued with an ex parte reexamination certificate or amended claims, suggesting the claims have already been subject to some USPTO scrutiny.
The commercial significance of this patent lies in the ubiquity of app-based time-tracking in shift-work industries including hospitality, retail, healthcare, and logistics. Deputy, Inc. is a well-funded SaaS platform operating in exactly this space. Mellaconic IP’s decision to assert this patent against Deputy — rather than pursue a portfolio licensing campaign — suggests targeted enforcement based on specific feature overlap. Any developer offering mobile punch-in/punch-out, geofenced clock-in, or biometric time-recording features should assess their exposure against the claim scope of US9986435B2.
Should your product team run an FTO against US9986435B2?
If your company develops or sells mobile time-tracking, workforce scheduling, or attendance-management software — particularly products with app-based clock-in features — US9986435B2 warrants a freedom-to-operate review. Mellaconic IP has demonstrated a willingness to litigate this patent to the three-year mark in a major patent venue. The lack of any public invalidity finding means the patent cannot be designed around or dismissed based on this case alone.
PatSnap Eureka’s FTO Search Agent can map your product’s feature set against the claim language of US9986435B2, identify prior art that could support an IPR petition, and surface related patents in Mellaconic IP’s portfolio that may present adjacent risk. Rather than waiting for a demand letter, R&D and product teams can use Eureka to build a proactive clearance file before new time-tracking features ship.

What this case signals for the workforce-management software IP landscape
A quietly closed Delaware NPE case over time-tracking app patents carries real implications for SaaS workforce-management developers.
NPE enforcement of mobile time-tracking IP remains active in Delaware
Mellaconic IP’s willingness to litigate for over three years in Delaware signals that mobile workforce time-tracking patents are treated as commercially valuable enforcement assets. SaaS companies operating shift-scheduling or attendance-tracking products should conduct proactive FTO analysis against patents in this space, not assume NPE claims will resolve quickly.
No invalidity ruling means US9986435B2 remains a potential threat
Because the case closed without a claim construction order or invalidity finding entering the public record, US9986435B2 retains its presumption of validity. Competitors and adjacent technology developers cannot rely on this litigation to clear the patent. An IPR petition at the USPTO remains the most reliable route to a binding invalidity determination.
