Interface Security Systems v. Hawk Technology Systems — Dismissed With Prejudice After 808 Days
Interface Security Systems sought declaratory relief against Hawk Technology Systems over two video surveillance patents — US10499091B2 and US10945004B2 — covering interactive monitoring technology. The parties jointly moved to dismiss all claims with prejudice after 808 days of litigation, each bearing their own legal costs.
Declaratory judgment dismissed with prejudice in video surveillance IP dispute
Interface Security Systems, LLC, the operator of an IP Interactive Monitoring System, filed this declaratory judgment action on 26 October 2021 in the Eastern District of Michigan against Hawk Technology Systems, LLC — a company incorporated in both Florida and Michigan. The dispute centred on two patents: US10499091B2 and US10945004B2, both covering interactive video surveillance and monitoring system technology. Interface sought a court declaration that its products and services did not infringe Hawk’s patent rights, or alternatively that those rights were invalid.
The case closed on 12 January 2024 when the court granted a joint motion for dismissal with prejudice. All declaratory judgment claims were extinguished with each party bearing its own costs, expenses, and attorneys’ fees. Dismissal with prejudice is a final adjudication on the merits — Interface cannot refile the same declaratory claims against Hawk on these patents, and Hawk retains its patent rights but cannot pursue infringement claims against Interface that were the subject of this action.
The 808-day duration suggests the parties engaged in substantive litigation activity — likely including claim construction exchanges, discovery, and potentially settlement negotiations — before reaching a negotiated resolution. The mutual cost-bearing arrangement and joint filing of the dismissal motion are consistent with a private commercial settlement, though the public record is silent on any financial terms or licensing agreement. The fact that both a Florida and Michigan Hawk entity were named as defendants suggests a deliberate effort by Interface to extinguish all potential claims across corporate entities.

What ‘dismissed with prejudice’ means here
Dismissal with prejudice is a final, binding termination of the litigation. Interface cannot refile these declaratory judgment claims against Hawk on the same patents in any court. This forecloses future declaratory relief on US10499091B2 and US10945004B2 on the same grounds. For Hawk, it equally precludes pursuing the specific infringement claims that were the mirror image of Interface’s declaratory action in this venue and on these facts.
Final on the meritsJoint motion strongly suggests a private settlement
When both parties jointly move for dismissal with prejudice and each bears their own costs, it typically signals a negotiated resolution reached outside the court record — often a license, a covenant not to sue, or a commercial agreement. The public record discloses no financial terms. The mutual cost-bearing structure is consistent with a balanced settlement rather than a concession by either side, but the specific terms remain confidential.
Settlement likely inferredTwo Hawk entities named — strategic scope of dismissal
Interface named both a Florida and a Michigan-incorporated Hawk Technology Systems entity as defendants. This approach is consistent with a strategy to extinguish patent claims across all related corporate structures in a single proceeding, preventing a surviving entity from later asserting the same rights. The joint dismissal covering both Hawk entities suggests Interface obtained the comprehensive release it sought.
Both entities dismissedNo fee award — each party absorbs its own litigation costs
The court ordered each party to bear its own costs, expenses, and attorneys’ fees. In patent cases, fee shifting under 35 U.S.C. § 285 requires a finding of an ‘exceptional case.’ The absence of any fee award here is consistent with a negotiated resolution where neither party sought to characterise the other’s conduct as exceptional — reinforcing the inference of an amicable commercial settlement.

Stipulation of dismissal — official text
The court’s order grants a joint motion and dismisses all declaratory judgment claims with prejudice, with each party bearing its own costs. The phrasing ‘for the reasons stated therein’ signals the court accepted the parties’ own justification without independent findings, which is standard in consensual dismissals. The with-prejudice designation forecloses Interface from relitigating these claims, while the mutual cost order reflects balanced resolution — neither party extracted a fee award, consistent with a negotiated outcome rather than a litigated victory.
US10499091B2 and US10945004B2 — Interactive Video Surveillance Monitoring
US10499091B2 (application no. US15/614137) and US10945004B2 (application no. US16/681957) both sit within the interactive video surveillance and remote monitoring domain. These patents cover systems and methods enabling IP-based interactive monitoring — the kind of technology underpinning modern managed security services, remote video verification, and alarm response platforms. The continuation relationship between the two applications (the later application number suggests a continuation or continuation-in-part filing) is consistent with a portfolio strategy designed to extend protection across system components and operational methods.
For the managed security and video surveillance sector, these patents represent a meaningful enforcement risk. Hawk’s willingness to assert — or threaten assertion against — Interface, a named operator of an IP Interactive Monitoring System, suggests the patent claims are drafted broadly enough to capture commercial platform deployments, not merely niche implementations. Competitors offering remote video monitoring, interactive alarm response, or IP camera management platforms should assess whether their architectures fall within the claim scope of either patent, particularly given that Hawk retained both patents post-dismissal.
Should your product team run an FTO against US10499091B2 and US10945004B2?
If your organisation develops, sells, or operates IP-based interactive monitoring systems, managed video surveillance services, or remote alarm verification platforms, both Hawk patents warrant a freedom-to-operate review. The fact that a well-resourced operator like Interface chose to file a declaratory judgment action — and retained Fish & Richardson to do so — suggests the patents carry commercially credible claim scope. The dismissal with prejudice bars Interface specifically, not the broader market.
PatSnap Eureka’s FTO Search Agent can map the independent and dependent claims of US10499091B2 and US10945004B2 against your product architecture and flag overlap risks before launch or product update. Claim monitoring alerts will notify your team if Hawk or a successor files continuation patents or new assertions. Running an FTO now — while the patents are post-litigation but pre-expiry — gives product and legal teams the clearest window to design around or document non-infringement positions.

What this case signals for the video surveillance IP landscape
A dismissed declaratory action over interactive monitoring patents raises important questions for competitors, product teams, and IP counsel in the security tech sector.
Declaratory judgment is a proactive tool for monitoring system operators
Interface’s decision to file first — seeking a declaration of non-infringement — rather than waiting to be sued signals the value of proactive IP risk management. Companies operating interactive monitoring platforms that receive patent assertion letters should consider whether declaratory relief is preferable to a defensive posture. Filing in a chosen venue can set favourable procedural terms.
US10499091B2 and US10945004B2 remain live patents post-dismissal
Dismissal with prejudice bars Interface from relitigating these specific claims, but Hawk’s patents are not invalidated and remain enforceable against third parties. Any company in the interactive video surveillance or remote monitoring space should treat both patents as active risks and conduct freedom-to-operate analysis before deploying competing products or services.
Interface v Hawk — key questions answered
The case was dismissed with prejudice by joint motion on 12 January 2024, after 808 days of litigation. All declaratory judgment claims were extinguished, and each party was ordered to bear its own costs, expenses, and attorneys’ fees. No financial terms were disclosed in the public record.
Two patents were at issue: US10499091B2 (application US15/614137) and US10945004B2 (application US16/681957). Both relate to interactive video surveillance and monitoring system technology and are held by Hawk Technology Systems, LLC. Both patents remain in force following the dismissal.
Dismissal with prejudice is a final termination of the action on the merits. In a declaratory judgment case, it means the plaintiff — here Interface — cannot refile the same non-infringement or invalidity claims against Hawk on these patents. It equally forecloses Hawk from pursuing the mirror-image infringement claims that were the subject of Interface’s declaratory action.
Declaratory judgment actions allow a party that believes it faces a credible infringement threat to take the initiative — choosing the venue, setting the procedural timeline, and forcing resolution. This approach is common when a patent holder has sent licensing demands or assertion letters. The public record does not disclose the triggering communications, but the filing is consistent with Interface receiving a pre-suit assertion from Hawk.
No. Dismissal with prejudice ends the litigation but does not invalidate the patents. US10499091B2 and US10945004B2 remain enforceable against third parties. Only a successful inter partes review at the USPTO or a court judgment of invalidity would cancel the patent claims. Companies in the interactive monitoring space should treat both patents as active risks.
