BOE Technology v. Samsung Display: Foldable OLED Patent Suit Dismissed With Prejudice
BOE Technology Group filed suit against Samsung Display in the Eastern District of Texas, asserting four patents covering OLED display technology used in the Galaxy Z Fold 5 and Fold 6. The parties jointly stipulated to dismiss all claims with prejudice in 178 days — each side bearing its own costs, suggesting a negotiated resolution outside the public record.
BOE vs. Samsung: A Foldable Display Patent Dispute Resolved in Silence
On May 27, 2025, BOE Technology Group Co., Ltd. filed an infringement action against Samsung Display Co., Ltd. in the Eastern District of Texas before Judge Rodney Gilstrap, asserting four US patents — US12307976B2, US11695017B2, US12266309B2, and US11037994B2 — covering OLED display structures and configurations. The accused products were Samsung’s Galaxy Z Fold 5 and Fold 6 foldable smartphones, among the highest-profile devices in Samsung’s premium portfolio.
The case terminated on November 21, 2025, via a joint stipulation of dismissal with prejudice under Federal Rule of Civil Procedure 41. Judge Gilstrap accepted the stipulation and ordered all claims and counterclaims dismissed with prejudice, with each party bearing its own costs and fees. Dismissal with prejudice is final and on the merits — BOE is permanently barred from re-asserting these specific claims against Samsung in a new action.
Resolution in 178 days, before any claim construction or substantive motion practice typically signals a negotiated outcome — most likely a licensing agreement or broader commercial arrangement — though the public record is silent on terms. The mutual cost-bearing provision is consistent with a negotiated resolution rather than a unilateral concession. What drove the settlement, including any royalty flows or cross-license terms, remains undisclosed.

Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41 dismissal with prejudice is a final, merits-level disposition
A Rule 41 joint stipulation of dismissal with prejudice is treated as a final judgment on the merits under US procedural law. Unlike a voluntary dismissal without prejudice, this order permanently extinguishes BOE’s right to re-litigate these four patent claims against Samsung Display. The Court’s order also denied all pending relief as moot and directed the Clerk to close the case entirely.
Permanent bar on re-filingBOE gives up its litigation leverage — but likely extracted commercial value
By agreeing to dismiss with prejudice, BOE Technology permanently surrenders the right to pursue these four specific patent claims against Samsung Display. However, the mutual cost-bearing provision and rapid resolution — well before substantive discovery — are consistent with BOE having secured a licensing arrangement or broader commercial deal. The public record discloses no admission of invalidity or non-infringement by BOE.
Likely negotiated exitSamsung Display escapes liability on these four patents — for now
Samsung Display obtains a permanent dismissal of all four patent claims asserted by BOE without any public finding of infringement or liability. The with-prejudice nature of the dismissal provides Samsung with strong protection against re-assertion of these specific claims. However, BOE holds a substantial OLED patent portfolio, and the dismissal does not preclude future suits on different patents covering similar foldable display technology.
Protected on these claims onlyThe BOE–Samsung display IP dynamic extends far beyond this single docket
BOE and Samsung Display are the world’s two largest OLED panel manufacturers and compete directly for Apple, Xiaomi, and foldable device supply contracts. Patent litigation between them typically signals — and often resolves through — broader supply or licensing negotiations. This early dismissal suggests the IP dispute may have been a lever in a wider commercial negotiation, a pattern consistent with large-scale display industry cross-licensing practice.

Official order — verbatim text
The Court’s order accepting the joint stipulation is procedural in nature — it makes no finding on infringement, validity, or claim scope. The with-prejudice designation carries substantive consequence: it operates as a final adjudication on the merits for res judicata purposes, permanently barring BOE from re-asserting these four claims against Samsung Display. The mutual cost-bearing order reflects the parties’ agreed terms and forecloses any fee-shifting argument under 35 U.S.C. § 285. No claim construction record was established, leaving the technical scope of the four patents unresolved in public proceedings.
US12307976B2 — OLED display structures for foldable smartphones
The four asserted patents — US12307976B2 (App. US18/100427), US11695017B2 (App. US16/760236), US12266309B2 (App. US18/158254), and US11037994B2 (App. US16/393872) — collectively cover OLED display panel architectures, thin-film structures, and component configurations relevant to foldable smartphone displays. Application dates spanning US16 and US18 series suggest filings across roughly 2018–2023, covering both foundational and more recent OLED engineering innovations that BOE has developed for next-generation flexible display products.
BOE is one of the world’s largest OLED panel manufacturers and holds a substantial US patent portfolio in display technology. Asserting these patents against Samsung Display — the dominant supplier of OLED panels for premium smartphones including Apple’s iPhone and Samsung’s own Galaxy foldables — signals that BOE is actively monetising its IP position as it gains market share in the foldable panel segment. Companies developing or sourcing foldable OLED displays should treat BOE’s US patent estate as a material FTO consideration, particularly for products using flexible panel architectures similar to the Galaxy Z Fold line.
Should your foldable display product be assessed against US12307976B2 and the BOE portfolio?
Any company designing, sourcing, or selling foldable smartphones, tablets, or wearables incorporating OLED panels should consider an FTO analysis against BOE Technology’s US patent estate. This case demonstrates that BOE is willing to assert its patents in US courts against the world’s largest display manufacturers. OEMs integrating foldable OLED panels — regardless of whether they source from BOE, Samsung Display, or LG Display — face potential exposure if their panel architectures overlap with the structures claimed in these four patents.
PatSnap Eureka’s FTO Search Agent enables R&D and IP teams to map product features against the full BOE OLED patent portfolio, identify claim overlap with US12307976B2, US11695017B2, US12266309B2, and US11037994B2, and surface design-around opportunities before product launch. Eureka’s litigation monitoring layer also tracks BOE’s enforcement history across jurisdictions, allowing legal teams to anticipate enforcement risk as BOE’s foldable display market share grows.

What this case signals for the foldable OLED display IP landscape
BOE’s four-patent campaign against Samsung’s Galaxy Z Fold line reflects a broader escalation in foldable display IP enforcement that IP teams should track closely.
E.D. Texas remains the venue of choice for Chinese display patent plaintiffs
BOE filed before Judge Gilstrap — arguably the most experienced patent jurist in the US — in the Eastern District of Texas, consistent with a pattern of Chinese technology companies using this venue for high-value IP assertions. Defendants in the foldable display space should maintain standing E.D. Tex. litigation readiness for BOE and its subsidiaries.
Dismissal speed suggests the complaint functioned as a licensing trigger, not a trial play
Resolution in 178 days — before claim construction — is atypical for contested patent litigation in E.D. Tex. This timeline is most consistent with the complaint serving as a catalyst for licensing or supply-chain negotiations already underway. R&D and procurement teams at OLED display buyers should recognise that patent filings in this space may signal commercial leverage plays rather than imminent litigation risk.
BOE v Samsung — key questions answered
BOE asserted four US patents: US12307976B2, US11695017B2, US12266309B2, and US11037994B2. All four cover OLED display structures and configurations. The accused products were Samsung’s Galaxy Z Fold 5 and Fold 6 foldable smartphones.
The parties filed a joint stipulation of dismissal with prejudice under Rule 41 of the Federal Rules of Civil Procedure. The Court accepted the stipulation and ordered all claims and counterclaims dismissed. The public record does not disclose the terms driving the joint dismissal, though the mutual cost-bearing provision is consistent with a negotiated resolution.
No. A dismissal with prejudice operates as a final judgment on the merits and bars BOE from re-asserting these four specific patent claims against Samsung Display in any future action under the doctrine of res judicata. BOE could, however, assert different patents from its portfolio in a new action.
The Court ordered each party to bear its own attorneys’ fees and costs, meaning no fee-shifting award was made under 35 U.S.C. § 285 or any other basis. This provision is typically negotiated by the parties and inserted into the stipulation. It suggests neither side sought to characterise the other’s litigation conduct as exceptional or unreasonable.
Judge Gilstrap of the Eastern District of Texas handles more patent cases than any other federal judge in the US. His court is a preferred venue for patent plaintiffs due to its procedural efficiency and patent-experienced bench. BOE’s choice of this venue and judge is consistent with a deliberate enforcement strategy targeting high-value defendants in a plaintiff-friendly jurisdiction.
