Feit Electric v. Savant Technologies: LED Patent Case Stayed for USPTO Review
Feit Electric Company filed suit against Savant Technologies in the Northern District of Ohio, asserting two LED lighting patents against GE-branded filament and ST19 lamp products. After 519 days on the docket, the court stayed proceedings pending USPTO patent review and removed the case from its active docket, with a 30-day window to reopen if USPTO proceedings merit it.
LED lighting patent dispute paused for USPTO patent office review
Feit Electric Company, Inc. filed this infringement action on March 13, 2024 in the Northern District of Ohio against Savant Technologies, LLC, asserting US8614539B2 and US8604678B2 — both LED lighting patents — against a range of GE-branded LED products, including Pearl Filament and ST19 lamp models sold under model numbers such as LED6DBC/DL9GCQWF-3T and LED5DST19M/DL9GCQWF-2T. Judge Bridget Meehan Brennan presided over the matter throughout its duration on the active docket.
On April 1, 2025, the court entered an order staying the case pending the conclusion of USPTO proceedings — a mechanism typically triggered when parallel inter partes review (IPR) or similar post-grant proceedings are initiated against the asserted patents. On August 14, 2025, the court went further, removing the case from its active docket entirely and directing plaintiff’s counsel to move to reopen within 30 days of any USPTO proceedings becoming final, under penalty of potential dismissal.
The 519-day timeline reflects a case that progressed through initial pleadings before hitting the USPTO stay threshold. The public record does not confirm which specific USPTO proceeding — IPR, ex parte reexamination, or otherwise — triggered the stay, nor its current status. The 30-day reopen window signals that resolution hinges entirely on the patent office outcome: if the patents survive USPTO review intact, Feit Electric can revive the litigation; if they are invalidated or substantially amended, the infringement claims may never return to court.
Filing to Case Removed in 519 days
519 days on docket before removal — typical patent stays can extend litigation by 12–24+ months
Case removed from active docket: what the USPTO stay means for both parties
Court removes case pending USPTO patent office review
A litigation stay pending USPTO proceedings is typically granted when parallel post-grant review (such as IPR) is filed against the asserted patents. The court’s August 2025 order goes beyond a simple stay — it removes the case from the active docket entirely. This is a stronger administrative step, effectively suspending the litigation clock and signalling the court’s preference not to expend judicial resources until patent validity is resolved at the USPTO level.
Stay + docket removalFeit Electric’s claims preserved but contingent on USPTO survival
Feit Electric retains the right to reopen this case, but only within 30 days of USPTO proceedings becoming final and only if merited — meaning the patents must survive review in a form that supports the infringement claims. This structure places the litigation’s fate squarely on the patent office outcome. If the asserted claims are cancelled or narrowed at the USPTO, Feit’s ability to pursue infringement relief against Savant’s GE LED products is materially weakened or extinguished.
Contingent revival windowSavant avoids trial while USPTO proceedings run their course
For Savant Technologies, the docket removal represents a meaningful near-term reprieve from litigation risk, discovery costs, and injunction exposure. If Savant initiated IPR or reexamination proceedings, the stay strategy has succeeded at the district court level. The outcome at the USPTO will determine whether Savant ultimately escapes liability entirely or faces a reinvigorated infringement case. Failure by Feit to meet the 30-day reopen deadline could also result in outright dismissal.
USPTO proceedings decisiveGE LED filament and ST19 product lines remain in legal uncertainty
The GE-branded LED products named in this suit — covering filament and ST19 lamp form factors — remain under a patent cloud until the USPTO proceedings conclude. Competitors and retailers evaluating these product lines should note that infringement liability has not been adjudicated on the merits. The case structure suggests that the validity of the underlying LED lighting patents, rather than infringement facts, will be the determinative issue. A USPTO decision upholding the patents would likely reignite district court proceedings.

Official order — verbatim text
The court’s August 14, 2025 order is administrative rather than dispositive — it removes the case from the active docket following a prior stay entered April 1, 2025, and does not adjudicate infringement or validity on the merits. The operative language conditions any future revival on Feit Electric moving to reopen within 30 days of USPTO proceedings becoming final, and explicitly warns that non-compliance may result in dismissal. This framing suggests the court views the patent office proceedings as potentially case-dispositive, and is unwilling to hold the case in administrative limbo indefinitely without a plaintiff-driven revival mechanism.
US8614539B2 & US8604678B2 — LED lighting control patents at issue
US8614539B2 and US8604678B2 are both United States patents issued to Feit Electric, with application numbers US13/273215 and US13/273212 respectively — closely related filings suggesting a common prosecution origin and shared inventive concept. Both patents fall within the LED lighting control and driver circuitry domain, a technically active area governing how LED lamps manage power conversion, dimming compatibility, and thermal performance. The near-identical application numbers indicate these were filed contemporaneously, likely as divisional or continuation applications targeting distinct claim sets from the same core invention.
For competitors in the LED bulb market — particularly those supplying filament-style and ST19 omnidirectional lamp form factors under licensed or OEM arrangements — these patents represent a meaningful freedom-to-operate consideration. The products named in the complaint are GE-branded retail SKUs, suggesting that the patent claims are broad enough to read on commercially mainstream LED product lines. Any company designing or importing LED lamps with similar driver architectures should assess claim scope against these patents, particularly given that their validity remains unresolved pending USPTO proceedings.
Should your LED lamp product line be cleared against US8614539B2?
R&D teams and product managers developing or sourcing LED filament, ST19, or similarly architected omnidirectional LED bulbs should treat these two Feit Electric patents as active FTO flags. The fact that GE-branded mainstream retail products were named as accused products suggests the patent claims are not narrowly scoped to proprietary designs — they may read on standard LED driver and control architectures used across the industry. With USPTO validity proceedings ongoing, the risk profile is dynamic: claims may narrow, survive intact, or be cancelled.

What this case signals for the LED lighting IP landscape
USPTO post-grant proceedings are reshaping how LED lighting patent disputes play out in district courts — this case is a clear illustration.
USPTO stays are a viable defence tool in LED lighting patent cases
This case demonstrates that defendants in LED lighting infringement suits can effectively redirect litigation to the patent office level. A successful stay not only halts district court proceedings but, as here, can result in full docket removal — eliminating near-term trial risk and shifting the battlefield to USPTO validity proceedings where challenger success rates in IPR have historically been significant.
Patent holders face a strict reopen deadline after USPTO stay orders
The court’s 30-day reopen window after USPTO finality is a compliance trap for patent holders. Feit Electric must actively monitor the USPTO proceeding status and act promptly. Missing this window risks outright dismissal of infringement claims that have not been adjudicated on the merits — a procedural loss that would benefit Savant Technologies without any substantive validity or infringement ruling.
Feit v Savant — key questions answered
As of August 14, 2025, the case has been removed from the active docket of the Ohio Northern District Court by Judge Bridget Meehan Brennan. The case was previously stayed on April 1, 2025, pending USPTO proceedings. Feit Electric’s counsel must move to reopen within 30 days of those proceedings becoming final, or the case may be dismissed.
Feit Electric asserted US8614539B2 (application US13/273215) and US8604678B2 (application US13/273212), two related LED lighting patents filed with near-identical application numbers suggesting a common prosecution origin. Both relate to LED lamp driver and control circuitry technology.
The accused products are GE-branded LED lamps: the GE LED Pearl Filament (Model No. LED6DBC/DL9GCQWF-3T and LED6DBC/SW9GCQWF-3T) and GE LED ST19 lamps (LED5DST19M/DL9GCQWF-2T and LED5DST19M/SW9GCQWF-2T), covering both daylight and soft white variants.
The court entered a stay on April 1, 2025 pending USPTO proceedings — most likely an inter partes review or reexamination filed against the asserted patents. On August 14, 2025, the court went further and removed the case from its active docket, conditioning any revival on Feit Electric moving to reopen within 30 days of USPTO proceedings becoming final.
The court’s August 14, 2025 order explicitly warns that failure to comply with the 30-day reopen deadline may result in denial of the motion to reopen and dismissal of the action. This means the infringement claims could be extinguished without any merits adjudication, effectively ending the litigation in Savant Technologies’ favour on procedural grounds.
