IFPower Co. v. Anker Innovations: Wireless Charging Suit Dismissed in 43 Days
IFPower Co., Ltd. filed suit against Anker Innovations Ltd. in the Western District of Texas alleging infringement of two wireless charging patents — US7298361B2 and US7863860B2 — across multiple Anker charging products. The plaintiff voluntarily dismissed all claims without prejudice just 43 days after filing, before Anker filed any answer.
Fast voluntary exit in a wireless charging patent dispute
On December 11, 2023, IFPower Co., Ltd. filed a patent infringement complaint against Anker Innovations Ltd. in the Western District of Texas before Chief Judge Robert Pitman. The action asserted two patents — US7298361B2 and US7863860B2 — directed at wireless charging technology, and identified several Anker products as allegedly infringing: the 3-in-1 Cube, Anker 315 Wireless Charging Pad, Anker 544 Wireless Charger, and Anker Wireless Charging product line.
On January 22, 2024 — just 43 days after filing — IFPower filed a notice of voluntary dismissal of all claims without prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because Anker had not yet served an answer or a motion for summary judgment, no court order was required; the notice was self-effectuating and immediately terminated the case. The court confirmed closure on January 23, 2024.
A 43-day lifespan strongly suggests the parties reached an early commercial arrangement, or that IFPower elected to reassess its litigation strategy before incurring significant costs. The public record does not disclose any settlement terms, licensing agreement, or the specific reason for withdrawal. Critically, dismissal without prejudice leaves IFPower free to refile the same claims — the dispute may not be permanently resolved.
Filing to voluntary dismissal in 43 days
Case lifespan — resolved before defendant filed an answer
Voluntary dismissal without prejudice under Rule 41(a)(1)(A)(i)
Rule 41(a)(1)(A)(i): Plaintiff’s unilateral exit right
Federal Rule of Civil Procedure 41(a)(1)(A)(i) allows a plaintiff to dismiss an action unilaterally — without a court order — by filing a notice before the defendant serves an answer or motion for summary judgment. Because Anker had not responded, IFPower’s notice was self-effectuating. The case terminated the moment the notice was filed, with no judicial intervention required.
No court order neededWithout prejudice: the door stays open for IFPower
Dismissal without prejudice means the case ends but the claims are not extinguished on the merits. IFPower retains the legal right to refile the same infringement claims against Anker based on the same patents and products. This contrasts with a dismissal with prejudice, which would permanently bar refiling. The public record here is silent on whether a settlement or licence drove the withdrawal — either scenario is consistent with a without-prejudice exit.
Claims preserved43-day resolution: what early dismissal typically signals
A case resolved before the defendant even files an answer is highly compressed relative to the typical patent litigation lifecycle in W.D. Texas. This timeline is consistent with either a rapid pre-litigation licensing discussion that reached conclusion shortly after filing, or a plaintiff decision to regroup — potentially to refile in a different venue or with refined claim mapping. No facts in the public record confirm either interpretation.
Pre-answer exitAnker faces no current liability — but is not fully clear
Anker Innovations exits this action with no judgment, no injunction, and no recorded costs order against it. However, because the dismissal was without prejudice, Anker cannot treat the matter as finally resolved. If IFPower refiles — whether in W.D. Texas or another district — Anker will need to respond and defend on the merits of the wireless charging patents. Continued product monitoring against US7298361B2 and US7863860B2 is advisable.

Stipulation of dismissal — official text
The court’s notation confirms the dismissal was self-effectuating under Rule 41(a)(1)(A)(i) — no merits analysis, no ruling on validity or infringement occurred. The phrasing ‘terminates the case in and of itself’ underscores that Anker never formally appeared in the litigation. For Anker, this means no adverse findings; for IFPower, all claims and legal theories remain intact and refiling is permissible at any time within applicable statutes of limitation.
US7298361B2 & US7863860B2 — Wireless Charging Technology Patents
US7298361B2 (application no. US11/004890) and US7863860B2 (application no. US12/149303) are IFPower-held patents directed at wireless charging technology. Filed in the mid-2000s, these patents predate the broad commercialisation of Qi-based consumer wireless charging and cover foundational aspects of wireless power transfer systems. The products named in the complaint — including multi-device charging cubes and standalone pads — represent the current mainstream expression of the technology these patent families anticipated.
For companies operating in the consumer charging hardware segment, patents of this vintage and subject matter carry meaningful enforcement risk. IFPower’s willingness to file — and its choice of W.D. Texas — suggests the patents are maintained in active licensing posture. Any competitor manufacturing or distributing multi-device wireless chargers, 3-in-1 charging stations, or Qi pad configurations should treat these patent numbers as live enforcement signals, not historical artefacts.
Should your team run an FTO against US7298361B2 and US7863860B2?
If your product roadmap includes wireless charging pads, multi-device charging hubs, or 3-in-1 charging stations, the patents asserted in this case are directly relevant. The Anker products named — including a charging cube and standalone Qi pads — are representative of the category. Any company shipping comparable form factors, particularly in markets where IFPower has established rights, should conduct a freedom-to-operate analysis before launch or expansion.
PatSnap Eureka’s FTO Search Agent can map your product’s technical features against the independent claims of US7298361B2 and US7863860B2, flagging overlap and identifying design-around opportunities. Eureka’s claim monitoring tools will also alert you if either patent is cited in new filings, assigned, or asserted in fresh litigation — giving your team the earliest possible signal of renewed enforcement activity in this technology area.

What this case signals for the wireless charging IP landscape
A rapid voluntary exit in W.D. Texas involving two wireless charging patents warrants attention from any company in the consumer charging hardware space.
Without-prejudice exits preserve plaintiff optionality — monitor for refiling
IFPower’s withdrawal does not extinguish its rights. Companies operating in the wireless charging category — particularly those selling multi-device or pad-style chargers — should track US7298361B2 and US7863860B2 for any subsequent actions. A without-prejudice dismissal in a fast timeline is a known precursor to refiling once strategy is refined.
W.D. Texas remains an active venue for charging-tech patent enforcement
IFPower’s choice of the Western District of Texas is consistent with broader plaintiff-friendly venue trends. Even a short-lived filing here generates public record and signals patent holder intent. Competitors and distributors of Anker-category products should factor W.D. Texas risk into any FTO assessment for wireless charging SKUs.
IFPower v Anker — key questions answered
IFPower Co., Ltd. filed a patent infringement suit against Anker Innovations Ltd. in the Western District of Texas on December 11, 2023, asserting US7298361B2 and US7863860B2 over wireless charging products. IFPower voluntarily dismissed all claims without prejudice on January 22, 2024 — 43 days after filing — before Anker served any answer.
Dismissal without prejudice means IFPower’s infringement claims were not decided on their merits and are not extinguished. IFPower retains the legal right to refile the same claims based on US7298361B2 and US7863860B2 against Anker at any time within the applicable statute of limitations. No judgment, injunction, or costs order was entered against either party.
The complaint identified four Anker products: the 3-in-1 Cube, Anker 315 Wireless Charging Pad, Anker 544 Wireless Charger, and Anker Wireless Charging product line. These products were alleged to infringe US7298361B2 and US7863860B2, both directed at wireless charging technology.
Under Federal Rule of Civil Procedure 41(a)(1)(A)(i), a plaintiff may voluntarily dismiss an action without a court order by filing a notice before the opposing party serves an answer or motion for summary judgment. Because Anker had not filed either, IFPower’s dismissal notice was self-effectuating — the case terminated automatically upon filing without any judicial ruling required.
Anker faces no current liability — no judgment or injunction was entered. However, the dismissal was without prejudice, meaning IFPower can refile. Anker received no formal clearance on the merits of US7298361B2 or US7863860B2. Companies in similar product categories should not treat this dismissal as a signal that these patents are invalid or unenforceable.
