Induction Devices LLC v. Tempur-Pedic: Five-Patent Infringement Action Dismissed
Induction Devices LLC asserted five patents covering contactless consumer credit card technology against Somnigroup International (Tempur-Pedic) in the Eastern District of Texas. The plaintiff voluntarily dismissed the case without prejudice after just 114 days, before any substantive merits ruling was issued.
A five-patent contactless payment suit ends before it begins
On August 13, 2025, Induction Devices LLC filed suit against Somnigroup International Inc., doing business as Tempur-Pedic, in the U.S. District Court for the Eastern District of Texas before Judge Rodney Gilstrap. The complaint asserted five patents — US7899145B2, US8543628B2, US7449926B2, US8190885B2, and US8370543B1 — all directed to contactless consumer credit card technology. The choice of defendant is notable given Tempur-Pedic’s primary identity as a sleep products brand rather than a payment technology company, suggesting the infringement theory may have targeted branded co-branded or private-label credit card programs.
The case closed on December 5, 2025, 114 days after filing, when plaintiff filed a Notice of Voluntary Dismissal Without Prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i). The court accepted and acknowledged the dismissal, ordering each party to bear its own costs, expenses, and attorneys’ fees. Because the dismissal was without prejudice, Induction Devices retains the legal right to refile claims on the same patents against the same or different defendants, subject to applicable statutes of limitations.
The swift resolution — before any responsive pleading or scheduling order — is consistent with several scenarios: a confidential settlement reached informally, a licensing arrangement negotiated off-record, or a plaintiff reassessing the strength of its infringement theory after defendant engagement. The public record is silent on the underlying commercial rationale. What is clear is that no merits determination was made, leaving the validity and enforceability of the five asserted patents entirely unresolved by this proceeding.

Voluntarily dismissed: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i) dismissal: no court consent needed
Under Federal Rule of Civil Procedure 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice before the defendant serves an answer or a motion for summary judgment. This is a unilateral right — the court’s role is purely ministerial. The dismissal here was explicitly without prejudice, meaning the action is terminated but no res judicata bar attaches to the underlying patent claims.
No merits adjudicationWithout prejudice confirmed — refiling remains an option
The verdict expressly states dismissal ‘without prejudice.’ This is legally significant: Induction Devices LLC is not barred from asserting the same five patents against Tempur-Pedic or other parties in future proceedings. A ‘with prejudice’ dismissal would have extinguished those rights. The public record does not disclose whether any licensing agreement, settlement payment, or other commercial arrangement accompanied the dismissal — that dimension remains entirely private.
Refiling right preservedTempur-Pedic exits without admission, but no patent invalidation
Somnigroup International obtains immediate relief from the litigation, with costs and fees retained by each party. Critically, the dismissal without prejudice means Tempur-Pedic received no declaration of non-infringement and no invalidity ruling on the five asserted patents. The company remains exposed to reassertion of the same patents, whether by Induction Devices LLC directly or through any successor in interest to the portfolio.
No invalidity ruling obtainedFive contactless payment patents remain live enforcement tools
Because no court ruled on validity or infringement, all five patents in the Induction Devices portfolio — covering contactless consumer credit card technology — remain fully enforceable. Companies operating branded contactless card programs, co-branded retail credit products, or related payment infrastructure should be aware that this portfolio has been actively asserted. The Eastern District of Texas venue choice also signals a plaintiff willing to litigate in a patent-friendly forum.

Official order — verbatim text
The court’s order is purely procedural — it accepts and acknowledges the voluntary dismissal filed by Induction Devices LLC under Rule 41(a)(1)(A)(i), confirms the without-prejudice character of the dismissal, and orders each side to bear its own fees and costs. No claim was adjudicated on the merits. The phrase ‘all claims for relief not explicitly granted herein are DENIED AS MOOT’ is standard housekeeping language and carries no substantive implication for patent validity or infringement liability. For Tempur-Pedic, there is no declaratory judgment of non-infringement; for Induction Devices, the five patents remain unimpaired as enforcement assets.
US7899145B2 and four related patents — contactless consumer credit card technology
The five asserted patents — US7899145B2, US8543628B2, US7449926B2, US8190885B2, and US8370543B1 — were filed between approximately 2006 and 2011, placing their priority dates squarely in the formative era of contactless payment standardization. The portfolio appears directed to induction-based communication and authentication methods for consumer credit cards, a technical domain that underpins NFC and RFID payment infrastructures now ubiquitous in branded and co-branded retail credit programs. The breadth of five patents across multiple application chains suggests a portfolio built to cover both device-level and system-level implementations.
From a competitive intelligence standpoint, a portfolio of this vintage and scope — covering contactless payment infrastructure at a foundational level — carries meaningful assertion leverage across a wide range of defendants, from card issuers and co-brand retail partners to payment terminal manufacturers. The decision to assert against Tempur-Pedic specifically, a consumer goods brand rather than a payment technology company, is consistent with targeting entities that operate branded credit card programs as ancillary commercial products. Any company in the branded retail credit or contactless payment ecosystem should assess exposure across all five patents, which remain valid and enforceable.
Should you run an FTO against US7899145B2 and the Induction Devices portfolio?
If your organization operates, issues, or co-brands contactless consumer credit card products — or manufactures hardware that reads or processes contactless payment credentials — the Induction Devices portfolio warrants formal freedom-to-operate analysis. The without-prejudice dismissal against Tempur-Pedic confirms this portfolio is actively managed and being deployed in litigation. A single unreviewed patent from this five-patent family could represent a blocking position on your payment product roadmap.

What this case signals for the contactless payment IP landscape
A five-patent assertion resolved in 114 days without merits review leaves significant uncertainty for companies across the branded contactless payment ecosystem.
Early voluntary dismissals mask — not resolve — patent risk
A Rule 41(a)(1)(A)(i) dismissal without prejudice extinguishes the case, not the patents. Any company that received a demand letter or was targeted in a similar complaint involving this portfolio should treat the five Induction Devices patents as live risk, not resolved risk. No invalidity finding was made.
Eastern District of Texas remains a preferred venue for NPE assertions
Judge Gilstrap’s docket in the Eastern District of Texas continues to attract patent assertion entity filings. The filing here — even without a merits outcome — is consistent with a strategy of using the venue’s plaintiff-favorable reputation to drive early engagement with defendants. IP teams should monitor this court for related filings.
Induction v Somnigroup — key questions answered
Induction Devices LLC filed a patent infringement action against Somnigroup International (Tempur-Pedic) on August 13, 2025 in the Eastern District of Texas, asserting five patents on contactless consumer credit card technology. The plaintiff voluntarily dismissed the case without prejudice on December 5, 2025 — 114 days after filing — under Rule 41(a)(1)(A)(i). No merits ruling was issued and each party bears its own costs.
A dismissal without prejudice means the case is terminated but the underlying patent rights are not extinguished. Induction Devices LLC retains the ability to refile infringement claims based on any or all of the five patents — US7899145B2, US8543628B2, US7449926B2, US8190885B2, and US8370543B1 — against Tempur-Pedic or other defendants. No invalidity or non-infringement determination was made, so the patents remain fully enforceable assets.
The public record does not disclose the specific infringement theory. However, the assertion of contactless consumer credit card patents against a sleep products brand like Tempur-Pedic is consistent with targeting companies that operate co-branded or private-label consumer credit card programs as ancillary retail financial products. The choice of the Eastern District of Texas and Judge Gilstrap’s docket suggests a deliberate venue strategy by the plaintiff.
Yes. Because the dismissal was explicitly without prejudice, Induction Devices LLC is not legally barred from reasserting the same five patents against Somnigroup International in a future proceeding, subject to applicable statutes of limitations. Tempur-Pedic obtained no declaratory judgment of non-infringement, meaning its legal exposure on these five patents was not resolved by this case.
The five patents asserted were: US7899145B2 (App. No. 12/577477), US8543628B2 (App. No. 12/238893), US7449926B2 (App. No. 11/443110), US8190885B2 (App. No. 11/614257), and US8370543B1 (App. No. 13/154348). All five are directed to contactless consumer credit card technology and were filed between approximately 2006 and 2011.
