Seasonal Specialties v. LEDup Enterprises: Four LED Christmas Tree Patents, One IPR Stay

Seasonal Specialties brought a four-patent infringement action against LEDup Enterprises and Ledup Manufacturing Group over remote-operated and color-changing LED artificial Christmas trees. The Central District of California administratively closed the case after 441 days when the court granted an unopposed stay pending inter partes review of two of the four asserted patents at the USPTO’s Patent Trial and Appeal Board.

Case overview

LED Christmas Tree Patent Clash Paused by IPR Strategy

Seasonal Specialties filed suit on August 3, 2023 in the Central District of California against LEDup Enterprises, LLC and Ledup Manufacturing Group, Ltd., asserting infringement of four U.S. patents covering remote-operated and color-changing LED lighting systems. The accused products include the Starry Light Fraser Fir and Starry Light Flocked Christmas Trees — each featuring approximately 3,000 remote-operated LEDs — and the Grand Duchess Balsam Fir Christmas Tree, which incorporates roughly 2,250 color-changing LEDs.

On October 17, 2024, the court granted LedUp Manufacturing Group’s unopposed motion to stay the litigation pending inter partes review proceedings at the PTAB. LedUp had filed two IPR petitions on August 2, 2024, targeting patents US11096252B2 and US11533794B2 — two of the four patents-in-suit. The court administratively closed the case under JS-6 and ordered joint status reports every 90 days, while expressly warning plaintiff that non-compliance could result in dismissal without prejudice under Fed. R. Civ. P. 41(b).

The stay arrived at a notably early stage: no depositions had occurred, no scheduling order had issued, and no Markman hearing had been set. The court’s reasoning highlights the efficiency logic underlying IPR stays — potential claim cancellation or amendment in the IPR could eliminate entire claim sets or reshape claim construction, rendering pre-stay litigation work wasteful. The ultimate resolution of this dispute remains contingent on PTAB institution decisions and, if instituted, final written decisions on the two challenged patents, with the fate of the remaining two patents still to be litigated.

Dismissal terms

Case stayed pending IPR: what the administrative closure means for both sides

Legal mechanism

Administrative closure is not a dismissal — litigation is paused, not ended

An administrative closure under JS-6 removes the case from the court’s active docket for statistical purposes but does not dismiss it. The underlying claims remain live. The court retains jurisdiction and the case can be reopened. The trigger here is the IPR petitions filed against two of the four asserted patents — PTAB must decide whether to institute review within the statutory timeline before litigation resumes.

Litigation paused, not resolved
Patent holder outcome

Seasonal Specialties faces validity challenge on two core patents

By not opposing the stay, Seasonal Specialties preserved goodwill but accepted that two of its LED Christmas tree patents — US11096252B2 and US11533794B2 — will face PTAB scrutiny on validity. If any claims are cancelled, those claims cannot be asserted in this litigation per Fresenius. Two other asserted patents (US10080265B2 and US9554437B2) are not subject to the current IPR petitions and remain available for assertion when the stay lifts.

Two patents at PTAB risk
Defendant strategy

IPR petition is a classic dual-track defence play

LedUp’s filing of two IPR petitions while simultaneously seeking a litigation stay is a well-established defensive strategy. If PTAB institutes review and cancels claims, the litigation exposure on those patents evaporates. Even partial claim cancellation or amendment narrows damages and shifts claim construction. The unopposed nature of the motion suggests Seasonal Specialties calculated that resisting the stay carried little upside given the early case stage.

Dual-track IPR defence
Commercial implications

Holiday lighting IP disputes carry compressed commercial timelines

Christmas tree product disputes are seasonally acute — prolonged litigation uncertainty directly impacts SKU planning, retail purchasing cycles, and inventory commitments. The stay extends commercial uncertainty for both parties into at least 2025 and potentially beyond. Competitors in the LED artificial tree market should monitor PTAB institution decisions on US11096252B2 and US11533794B2 as early indicators of whether these claims will survive or be narrowed.

“WHEREAS, Defendant LedUp Manufacturing Group, LTD. (“LedUp”) has filed an Unopposed Motion to Stay Pending Inter Partes Review; WHEREAS, Plaintiff Seasonal Specialties (“Plaintiff”) does not oppose this Case 2:23-cv-06318-KK-AS Document 46 Filed 10/17/24 Page 1 of 4 Page ID #:798 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 2 ORDER Motion; WHEREAS, LedUp has moved this court to stay this case pending inter partes review (“IPR) of U.S. Patents Nos. 11,096,252 and 11,533,794. Two of the four patents are in-suit; WHEREAS, the IPR procedure is designed to (1) reduce the time the United States Patent and Trademark Office (“USPTO”) spends reviewing validity; and (2) minimize duplicate efforts by coordinating the IPR process with litigation; WHEREAS, on August 2, 2024, LedUp filed two IPR petitions with the USPTO setting forth substantial bases to invalidate two of the four patents in-suit; WHEREAS, the Patent Trial and Appeal Board (“PTAB”) is scheduled to decide whether to consider the institution of the IPR within three months and a final decision to institute the IPR within the statutory timeline of the next six months; WHEREAS, LedUp has requested that, in the alternative of a stay pending inter partes review, this matter be stayed until the PTAB issues its decision on whether to institute the IPR, withing six months, at which time the Court would have a clear picture and determination of the IPR status; WHEREAS, this case is in its early stages. Each party has served first discovery requests with responses continuing, no depositions have taken place, no scheduling by the Court nor briefing has occurred for the procedural stages of a patent case – including a Markman hearing and the resultant claim construction; WHEREAS, risk exists that, in the event that any claim amendments or other circumstances occur affecting claim construction during the IPR, any construction and claim interpretation resulting from the Markman hearing would have to be redone. WHEREAS, experts have not yet been identified, there is a pretrial scheduled for June 5, 2025, and the majority and substantial litigation activities have yet to be undertaken; WHEREAS, a stay would (1) allow the Court to reap the benefits of the IPR Case 2:23-cv-06318-KK-AS Document 46 Filed 10/17/24 Page 2 of 4 Page ID #:799 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 3 ORDER proceedings as to claim interpretation and to gain the PTO’s evaluation of new prior art as it impacts validity; and (2) allow the parties to avoid unneeded preparation and discovery for any claims that are canceled in the IPR; WHEREAS, the IPR has the potential to greatly simplify the case given that all of the claims of the two IPR patents are being challenged. In that event those claims are canceled, they cannot be asserted in this action. See, Fresenius USA, Inc. v. Baxter Intern., Inc., 721 F.3d 1330 (Fed. Cir. 2013); WHEREAS, the stay of this proceeding pending the IPR determination would develop the intrinsic record for the challenged patents and simplify how the remaining claims are construed by the Court after the Markman hearing. See, Aylus Networks, Inc. v. Apple Inc., 856 F.3d 1353, 1363 (Fed. Cir. 2017) (holding that statements made during IPR may support a finding of prosecution disclaimer when construing claims); WHEREAS, if any claims are amended during the IPR proceedings, the amendments will eliminate past damages, and the focus of this litigation would shift from the present claims to the amended claims; and WHEREAS, the stay will not unduly prejudice the Plaintiff; the Plaintiff does not oppose this Motion and is not seeking preliminary injunctive relief. THEREFORE, and consistent with the objectives of Congress in providing the IPR mechanisms for challenging patent validity, the Court grants a stay of this litigation pending the IPR proceeding. Plaintiff shall file a joint status report no later than January 14, 2025, and every ninety days thereafter, unless otherwise ordered by the Court. Plaintiff is expressly warned that failure to comply with this Order may result in dismissal of this action without prejudice for failure to prosecute and comply with Court orders. Fed. R. Civ.

The court’s stay order is a procedural disposition, not a merits ruling. The verbatim order grants an unopposed stay and administratively closes the case pending PTAB’s institution decision on two IPR petitions targeting US11096252B2 and US11533794B2. The explicit Fed. R. Civ. P. 41(b) warning signals the court’s expectation of active case management compliance, while the JS-6 closure preserves the ability to reopen without refiling. No claim construction, validity, or infringement findings have been made.

The four asserted patents cover remote-operated LED control and color-changing LED lighting technologies embedded in pre-lit artificial Christmas trees. US11096252B2 and US11533794B2 — the two patents challenged at PTAB — are the most recently issued, with application numbers in the US16 and US17 series suggesting filing dates in the 2019–2021 window. US9554437B2 represents an earlier generation of the underlying technology, while US10080265B2 sits in the middle of the portfolio’s development arc.

Seasonal Specialties’ four-patent portfolio suggests a layered enforcement strategy: core lighting control innovations are protected across multiple patent generations, creating overlapping coverage that complicates design-arounds. For competitors in the LED artificial tree market, the survival or cancellation of the two PTAB-challenged patents will materially affect the scope of freedom to operate. Even if those claims are narrowed, the two non-IPR patents remain live enforcement tools covering LED Christmas tree products with remote and color-change functionality.

Freedom to operate

Should you run an FTO against US11096252B2 and the Seasonal Specialties LED tree portfolio?

Any company manufacturing, importing, or distributing pre-lit LED artificial Christmas trees with remote-operated or color-changing lighting should treat this four-patent portfolio as an active enforcement risk. The pending PTAB proceedings do not eliminate FTO obligations — two patents are not under IPR challenge, and even challenged patents remain enforceable until claims are cancelled. Retailers sourcing LED Christmas tree products from OEM suppliers should confirm their supply chain has conducted clearance analysis.

PatSnap Eureka’s FTO Search Agent can map the claim scope of all four asserted patents against your specific product specifications — including LED count, remote control protocols, and color-change mechanisms. Eureka identifies prior art gaps, flags prosecution history statements that may limit claim reach, and monitors PTAB proceedings on US11096252B2 and US11533794B2 in real time, so your freedom-to-operate assessment stays current as IPR proceedings evolve.

Strategic implications

What this case signals for the LED holiday lighting IP landscape

Dual-track IPR-plus-stay strategies are reshaping how LED décor patent disputes resolve — or stall.

Early-stage IPR stays are increasingly granted when discovery is minimal

Courts in the Central District of California routinely weigh stage of litigation, prejudice to plaintiff, and simplification of issues when evaluating IPR stays. Here, with no depositions, no Markman schedule, and no claim construction briefing, all three factors favoured the stay. Companies facing infringement suits should assess IPR petition viability immediately upon service.

Claim cancellation risk is asymmetric across the four asserted patents

Two patents (US10080265B2 and US9554437B2) are not subject to the current IPR petitions. If the two challenged patents survive or are narrowed, Seasonal Specialties retains a potentially strong enforcement position on all four patents. If the IPR claims are cancelled, the remaining two patents still anchor infringement claims against the accused tree products.
