Pinn v. Nothing Technology: Patent Suit Over Nothing Ear Dismissed With Prejudice
Pinn, Inc. asserted US10455066B2 against Nothing Technology’s Ear (1), Ear (2), and Ear (Stick) wireless earbuds in the Western District of Texas. After 263 days, Pinn voluntarily dismissed all claims with prejudice before Nothing Technology filed any responsive pleading, with each side bearing its own legal costs.
Pinn’s earbud patent suit against Nothing Technology ends before defendant responds
On 1 September 2023, Pinn, Inc. filed a patent infringement action against Nothing Technology, Ltd. in the U.S. District Court for the Western District of Texas (Case No. 6:23-cv-00644), before Judge Xavier Rodriguez. The suit centred on US10455066B2, asserted against three Nothing Technology consumer audio products: the Nothing Ear (1), Nothing Ear (2), and Nothing Ear (Stick) wireless earbuds.
On 21 May 2024, Pinn filed a voluntary Notice of Dismissal with Prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i). The dismissal was entered before Nothing Technology had filed either an answer or a motion for summary judgment, meaning Pinn could dismiss as of right without court approval. Both parties agreed that each would bear its own costs and attorneys’ fees, suggesting a negotiated resolution or strategic withdrawal rather than a contested termination.
The case lasted 263 days — a timeline consistent with early-stage resolution before substantive litigation costs escalate. The dismissal with prejudice forecloses Pinn from re-filing the same claims against Nothing Technology on US10455066B2, which is commercially significant. What drove the withdrawal — licensing agreement, design-around by Nothing Technology, or a commercial decision to conserve litigation resources — is not disclosed in the public record.

Dismissed with prejudice: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i) dismissal: plaintiff’s right to exit before answer
Under FRCP Rule 41(a)(1)(A)(i), a plaintiff may dismiss an action as of right — without court order — before the defendant files an answer or a motion for summary judgment. Nothing Technology had filed neither, so Pinn’s exit required no judicial approval. The ‘with prejudice’ designation was voluntarily chosen by Pinn, making the dismissal a permanent bar to re-filing the same claims against this defendant.
Voluntary — no court order requiredDismissal with prejudice permanently closes Pinn’s claims on this patent
By electing dismissal with prejudice, Pinn relinquishes any future right to sue Nothing Technology on US10455066B2 for the conduct alleged in this action. This is a materially stronger concession than a without-prejudice exit. It suggests either a private resolution was reached — such as a licence or covenant not to sue — or Pinn made a strategic decision that further pursuit was not commercially viable against this defendant specifically.
Claims permanently extinguished vs. NothingNothing Technology avoids merits ruling — and the cost-fee split is neutral
Nothing Technology escaped without any finding of infringement or validity, and without the burden of attorneys’ fees shifting under 35 U.S.C. § 285. The agreed mutual cost-bearing arrangement is notable: it signals neither party secured a dominant position. Nothing Technology’s Ear product line faces no injunction or damages ruling, though the underlying patent US10455066B2 remains in force against other potential defendants.
No infringement finding; no fee awardUS10455066B2 survives — and remains a live threat to other earbud makers
The dismissal resolves only this bilateral dispute. US10455066B2 is not invalidated, and Pinn retains full enforcement rights against third parties in the wireless earbud market. Competitors and OEMs shipping similar wireless audio products should treat this as a signal that Pinn is active in assertion, and that the patent withstood no invalidation challenge here. A freedom-to-operate review against this patent remains commercially prudent.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) precisely and confirms Nothing Technology had filed no answer or summary judgment motion — establishing Pinn’s unilateral right to exit. The explicit ‘with prejudice’ election, combined with the agreed mutual cost-bearing clause, suggests this was a coordinated exit rather than a unilateral abandonment. No merits determination was reached, and the verdict text does not disclose any licence, payment, or settlement terms, leaving the commercial rationale a matter of inference from the public record.
US10455066B2 — wireless earbud device connectivity and control technology
US10455066B2, filed under application number US15/563937, covers technology in the wireless earbud connectivity and control domain — the core technical space underpinning true wireless stereo (TWS) consumer audio products. The patent was asserted against three distinct Nothing Technology SKUs — the Ear (1), Ear (2), and Ear (Stick) — indicating Pinn’s infringement theory spans a product generation range rather than a single device, suggesting the claims are likely directed at architectural or protocol-level features common across the lineup.
In the competitive TWS market — dominated by Apple AirPods, Samsung Galaxy Buds, Sony, and a growing cohort of challenger brands including Nothing Technology — patents covering wireless pairing, device handoff, and audio control interfaces represent high-value enforcement assets. US10455066B2’s assertion against a high-profile consumer brand like Nothing Technology signals that Pinn views the patent as commercially significant and broadly applicable. Competitors operating in the same technical space should evaluate their own product architectures against this patent’s claim scope as a priority IP risk management exercise.
Should you run an FTO against US10455066B2?
Any company designing, manufacturing, or importing true wireless stereo earbuds or similar wireless audio devices into the US market should assess exposure to US10455066B2. Pinn demonstrated willingness to assert this patent against a well-known consumer brand across multiple product generations. The patent’s claims were never narrowed or invalidated in this proceeding, and Pinn retains full enforcement rights. OEMs, white-label audio manufacturers, and TWS platform providers are all plausible future targets.

What this case signals for the wireless audio IP landscape
A pre-answer dismissal with prejudice in a consumer audio patent suit carries distinct strategic signals worth examining.
Pre-answer dismissals with prejudice often indicate private resolution
When a plaintiff voluntarily dismisses with prejudice before the defendant has even answered, it typically signals a negotiated outcome — whether a licence, a covenant not to sue, or a commercial settlement — rather than a simple abandonment of the case. The mutual cost-bearing arrangement here is consistent with that pattern. Neither party’s public filing discloses specific terms.
US10455066B2 remains an active enforcement asset — monitor its citation landscape
The patent was never subjected to an IPR, post-grant review, or validity challenge in this case. Its claims emerged from this litigation without any narrowing or adverse finding. Companies in the true wireless stereo (TWS) and wireless earbud market should track forward citations and further assertion activity around this patent as a priority enforcement signal.
Pinn v Nothing — key questions answered
Pinn, Inc. voluntarily dismissed all patent infringement claims against Nothing Technology, Ltd. with prejudice on 21 May 2024, under Rule 41(a)(1)(A)(i). The case was filed on 1 September 2023 in the Western District of Texas, asserting US10455066B2 against the Nothing Ear (1), Ear (2), and Ear (Stick). The dismissal came before Nothing Technology filed any answer, and both parties agreed to bear their own costs.
A dismissal with prejudice means Pinn cannot re-file the same claims against Nothing Technology on US10455066B2. However, the patent itself remains valid and enforceable — Pinn retains full rights to assert it against other defendants. The dismissal resolves only the bilateral dispute with Nothing Technology and does not affect the patent’s claim scope or legal status.
The public record does not disclose the specific reason. Pre-answer dismissals with prejudice in patent cases typically suggest a private resolution — such as a licensing agreement or covenant not to sue — or a strategic decision not to proceed with litigation against that particular defendant. The agreed mutual cost-bearing clause is consistent with a negotiated exit rather than a unilateral abandonment.
Pinn accused three Nothing Technology wireless earbud products of infringing US10455066B2: the Nothing Ear (1), Nothing Ear (2), and Nothing Ear (Stick). The fact that multiple product generations were named suggests Pinn’s infringement theory targeted features common across the product line rather than a design-specific element of a single device.
No — the dismissal binds only the two parties to this action. US10455066B2 remains enforceable against third parties. Other companies in the true wireless stereo and wireless earbud market remain potential targets for assertion. The case demonstrates Pinn’s willingness to assert this patent in the Western District of Texas, and companies with similar product architectures should consider a freedom-to-operate review against this patent.
