DS Advanced Enterprises v. Cooper Lighting: LED Lighting Patent Settled in 123 Days
DS Advanced Enterprises Ltd. filed a patent infringement action against Cooper Lighting, LLC in the Northern District of Georgia, asserting US11054118B2 against Utilitech and Halo brand lighting products. The parties reached an agreement in principle within 123 days, with the court administratively closing the case on April 11, 2025 pending a formal stipulation of dismissal.

123 days from filing to administrative closure — notably swift for a patent infringement action in N.D. Georgia
Agreement in principle reached: what the settlement means for both parties
Administrative closure pending formal dismissal stipulation
On April 7, 2025, both parties filed a Joint Motion to Stay All Deadlines, informing the court they had reached an agreement in principle. Judge Johnson administratively closed the case and ordered a stipulation of dismissal by May 12, 2025. Absent that filing, the court indicated it may dismiss with prejudice — a procedural device that preserves party rights while the settlement is finalised.
Agreement in principleWith or without prejudice? The public record is silent
The court’s order contemplates dismissal with prejudice if no stipulation is filed, but the actual stipulation’s terms — including whether it is with or without prejudice — are not yet reflected in the public docket as of the administrative closure date. A with-prejudice dismissal would bar DS Advanced from re-asserting US11054118B2 against Cooper Lighting on the same claims; a without-prejudice dismissal would preserve that right. Practitioners should monitor the docket for the final stipulation.
Terms undisclosedDS Advanced secures commercial resolution before trial
DS Advanced had a pending Motion for Partial Summary Judgment (Doc. 105) at the time of settlement, which was denied as moot. Settling at this stage — with substantive motions in play — suggests DS Advanced likely extracted meaningful commercial value without the cost and uncertainty of trial. The specific financial or licensing terms of the settlement are not publicly available.
Pre-trial resolutionCooper Lighting avoids adverse summary judgment ruling
Cooper Lighting, represented by Alston & Bird, faced a plaintiff’s partial summary judgment motion at the time settlement was reached. Resolving before that motion was adjudicated removed significant litigation risk. For a major lighting brand with Utilitech and Halo product lines at stake, settlement likely offered greater commercial certainty than continued litigation, though terms remain confidential.

Official order — verbatim text
The court’s April 11, 2025 order reflects a standard administrative closure mechanism used in the Northern District of Georgia when parties report settlement in principle. The denial of plaintiff’s partial summary judgment motion as moot — rather than on the merits — means no substantive claim construction or infringement ruling was made. The enforceability and scope of US11054118B2 remain judicially untested. All commercial and licensing terms of the settlement are confidential and not reflected in the public record.
US11054118B2 — LED Lighting Fixture Technology
US11054118B2, filed under Application No. 16/392731, covers LED lighting technology asserted by DS Advanced Enterprises against Cooper Lighting’s commercial product lines. The patent sits within the growing field of solid-state lighting, an area that has seen intensive IP activity as manufacturers transition from legacy light sources to LED-based systems. The specific claims were not adjudicated on the merits in this litigation, meaning claim scope remains defined solely by the patent text and prosecution history.
For the LED lighting sector, US11054118B2 represents an actively enforced patent held by a non-practising or licensing-focused entity. Its assertion against both Utilitech and Halo branded products — two distinct market-facing lines — suggests claim language broad enough to capture mainstream LED fixture architectures. Competitors, OEM suppliers, and distributors in the residential and commercial lighting space should assess whether their products fall within the patent’s independent claims before the settlement terms foreclose further public litigation intelligence.
Should your team run an FTO against US11054118B2?
Any company designing, manufacturing, importing, or distributing LED lighting fixtures — particularly those with architectural, residential, or commercial downlight form factors similar to Halo or Utilitech products — should consider US11054118B2 a live FTO risk. The patent survived litigation without being invalidated or narrowed, and the settlement terms are undisclosed, meaning no public licence terms or covenants not to sue can be inferred from this case alone.

What this case signals for the LED lighting IP landscape
A sub-123-day settlement in a lighting patent case with live summary judgment motions suggests both parties saw asymmetric risk in continued litigation.
Swift settlement with motions pending signals strong patent position
DS Advanced’s willingness to settle only after filing a partial summary judgment motion — and Cooper Lighting’s willingness to settle rather than defend it — is consistent with a patent holder holding meaningful claim scope. Competitors selling LED lighting products should treat US11054118B2 as an actively enforced asset warranting FTO review.
Utilitech and Halo brands signal broad product-line exposure
The assertion targeted two distinct Cooper Lighting product lines sold under different brand names, suggesting DS Advanced’s claim reads broadly across mainstream commercial and residential LED fixtures. Other manufacturers or distributors of similar product categories may face comparable exposure from this patent family.
Ds v Cooper — key questions answered
The case was administratively closed on April 11, 2025 after the parties reported reaching an agreement in principle. The court ordered a stipulation of dismissal by May 12, 2025. No merits ruling was issued. Settlement terms are not publicly disclosed.
DS Advanced asserted US11054118B2, filed under Application No. 16/392731, covering LED lighting technology. The patent was asserted against Cooper Lighting’s Utilitech and Halo brand product lines. The claims were never adjudicated on the merits in this litigation.
No. The case settled before any infringement determination was made. Plaintiff’s Motion for Partial Summary Judgment was denied as moot upon settlement. No court has ruled on whether Halo or Utilitech products infringe US11054118B2.
Administrative closure does not affect the patent’s enforceability. US11054118B2 remains an issued, enforceable patent. No invalidity or non-infringement ruling was made. DS Advanced retains the right to assert it against other defendants.
The case lasted 123 days from filing on December 9, 2024 to administrative closure on April 11, 2025. This is a notably short duration for a patent infringement action in the Northern District of Georgia, suggesting both parties moved quickly to settlement after initial litigation activity.
