CogniPower v. Fantasia Trading: USB-C Power Delivery Patents Dismissed Without Prejudice
CogniPower LLC filed suit in the District of Delaware asserting two reissued power-delivery patents against Fantasia Trading’s Anker-branded GaN USB-C chargers and power banks. Before any answer was filed, CogniPower voluntarily dismissed the action without prejudice — preserving its right to refile — after 246 days.
Reissued Power-Delivery Patents Dropped Before Anker Could Respond
CogniPower LLC filed this infringement action on 16 January 2025 in the District of Delaware before Judge Jennifer L. Hall. The complaint targeted Fantasia Trading, LLC — the U.S. entity behind the Anker brand — asserting two reissued patents, USRE047031E and USRE047713E, against at least ten Anker USB-C products including GaN-based PowerPort chargers and the PowerCore Fusion 5K PD power bank.
On 19 September 2025 — before Fantasia Trading filed any answer or moved for summary judgment — CogniPower invoked Fed. R. Civ. P. 41(a)(1)(A)(i) to voluntarily dismiss the action without prejudice. That procedural rule permits a plaintiff to exit as of right at this early stage, meaning no court approval was required and no merits ruling was issued. The dismissal without prejudice explicitly leaves CogniPower’s patent claims alive for potential future enforcement.
The 246-day arc from filing to dismissal — ending before substantive litigation commenced — is consistent with out-of-court resolution discussions, strategic reassessment of claim scope, or licensing negotiations, though the public record is silent on the underlying driver. Because no answer was filed, Fantasia Trading avoids any estoppel. CogniPower retains full optionality on its reissued patents, making the commercial outcome of this case materially uncertain from the outside.

Voluntarily dismissed: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i) — plaintiff’s unilateral exit right
Fed. R. Civ. P. 41(a)(1)(A)(i) allows a plaintiff to dismiss an action without court order at any time before the defendant serves an answer or a motion for summary judgment. CogniPower confirmed that neither had occurred. The dismissal is self-executing — no judicial approval needed — and the case closes immediately upon filing the notice.
No merits ruling issuedDismissal without prejudice preserves CogniPower’s right to refile
A dismissal without prejudice does not extinguish the underlying claims. CogniPower’s notice expressly states the dismissal is ‘without prejudice,’ meaning it may reassert USRE047031E and USRE047713E in a future action. This is categorically different from a dismissal with prejudice, which would bar refiling. The public record does not disclose whether a settlement, licensing deal, or strategic reconsideration drove this choice.
Claims remain liveFantasia Trading exits without admission, judgment, or estoppel
Because no answer was filed and no court ruled on the merits, Fantasia Trading faces no adverse judgment, no infringement finding, and no estoppel barring future defenses. However, the without-prejudice posture means the litigation risk from these two reissued patents has not been permanently resolved. Anker-branded power delivery products remain potentially exposed if CogniPower refiles.
No estoppel; risk remainsGaN USB-C charger market: patent exposure persists
CogniPower’s reissued patents cover power delivery controller technology relevant to GaN-based USB-C chargers — a high-growth product category. The without-prejudice dismissal suggests competitors and suppliers in this space cannot treat this case as a clean bill of health for their own designs. Any company shipping USB-C PD chargers into the U.S. market should consider whether USRE047031E and USRE047713E fall within their FTO risk perimeter.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1)(A)(i) and confirms no answer or summary judgment motion had been filed — a threshold that makes the dismissal self-effectuating with no judicial discretion involved. The explicit ‘without prejudice’ designation is the critical commercial operative: it preserves CogniPower’s entire cause of action. No claim was adjudicated, no validity finding was made, and no infringement determination exists on the record. Both parties’ legal positions remain exactly as they were at filing.
USRE047031E & USRE047713E — Reissued USB-C Power Delivery Controller Patents
USRE047031E and USRE047713E are reissued U.S. patents held by CogniPower LLC, stemming from application numbers US15/090929 and US15/168998 respectively. Reissue patents are granted by the USPTO to correct errors in an issued patent — a process that can also result in broadened or narrowed claims relative to the original grant. The underlying technology relates to power delivery controller architectures, directly relevant to the USB-C PD charging ecosystem that underpins GaN-based consumer chargers.
The products targeted — including GaN-based PowerPort Atom chargers and PowerCore Fusion power banks — represent Anker’s premium USB-C product lines. GaN power delivery technology is a fast-growing segment with multiple OEM and ODM suppliers, meaning these reissued patents may have enforceability implications well beyond Fantasia Trading. CogniPower’s decision to assert reissued claims suggests confidence in post-reissue scope, making these patents a live risk consideration for any company active in the USB-C PD charger supply chain.
Should you run an FTO analysis against USRE047031E and USRE047713E?
Any company designing, manufacturing, importing, or distributing USB-C power delivery chargers — particularly GaN-based products — should treat these two reissued patents as an active FTO risk item. The without-prejudice dismissal means CogniPower has not waived its enforcement rights, and reissued claim language may cover controller architectures across a broad range of products beyond those specifically named in this complaint.
PatSnap Eureka’s FTO Search Agent allows R&D and IP teams to map product-level technical features against the reissued claim sets of USRE047031E and USRE047713E, identify design-around opportunities, and monitor CogniPower’s broader portfolio for continuation or related filings. Given the pre-answer dismissal, proactive FTO work now — before any refiling — is materially lower cost than reactive litigation defense.

What this case signals for the USB-C power delivery IP landscape
A pre-answer dismissal involving reissued power delivery patents against a major consumer electronics brand rarely resolves the underlying IP tension.
Without-prejudice dismissal is not a clean exit for the market
CogniPower retains full ability to refile against Fantasia Trading or any other GaN USB-C charger manufacturer. The reissued patent status of USRE047031E and USRE047713E suggests the claims were already refined post-grant — potentially broadening their enforceability reach against newer product generations.
Pre-answer timing suggests negotiation, not defeat
Dismissals filed before the defendant answers — particularly in Delaware with experienced patent counsel on both sides — are frequently consistent with licensing discussions or settlement. Fish & Richardson’s involvement for Fantasia Trading indicates the defense was well-resourced, raising the likelihood of structured out-of-court engagement rather than unilateral withdrawal.
CogniPower v Fantasia — key questions answered
A dismissal without prejudice under Rule 41(a)(1)(A)(i) preserves CogniPower’s right to refile the same claims against Fantasia Trading or other defendants at any time within the applicable statute of limitations. No merits ruling was issued, so neither party has gained or lost any legal ground on the patent claims themselves.
CogniPower asserted two reissued U.S. patents: USRE047031E (application US15/090929) and USRE047713E (application US15/168998). Both are reissue patents covering power delivery controller technology relevant to USB-C GaN charging devices.
The complaint targeted at least ten Anker products including the PowerPort Atom PD1 (GaN), PowerPort Atom PD2 (GaN Tech), PowerPort Atom III Slim, PowerPort Atom III Slim (Four Ports), PowerPort+ Atom III (2 Ports), PowerPort C1, PowerPort III Nano A2616, PowerPort PD 2, 18W Power Delivery USB C Charger (PowerPort PD 1), and PowerCore Fusion 5K PD.
Pre-answer Rule 41(a)(1)(A)(i) dismissals without prejudice are consistent with several scenarios: licensing or settlement negotiations reaching a resolution, strategic reassessment of claim scope or venue, or a plaintiff preserving optionality while pursuing parallel targets. The public docket in this case is silent on the specific driver.
Reissue patents have undergone a second USPTO examination to correct errors in the original patent. This process can result in claims that are broader or narrower than the original grant. For FTO purposes, companies should not rely on prior clearance opinions based on the original patents — the reissued claims require independent analysis.
