WiTricity v. Ideanomics & WAVE: Wireless EV Charging Case Dismissed in 41 Days
WiTricity Corporation filed suit in Delaware against Ideanomics and WAVE asserting five wireless inductive EV charging patents, including US9184595. The case was dismissed without prejudice in just 41 days — not on the merits, but for failure to disclose a related pending case on the civil cover sheet, a procedural misstep Judge Hall found warranted more than simple reassignment.
A procedural own-goal ends WiTricity’s Delaware EV charging suit early
On July 30, 2024, WiTricity Corporation filed a patent infringement action in the District of Delaware against Ideanomics, Inc. and Wireless Advanced Vehicle Electrification, LLC (WAVE), asserting five U.S. patents directed to wireless inductive charging technology, including the anchor patent US9184595. The accused product is the WAVE by Ideanomics wireless inductive charging system, a commercial platform for electrified fleet and transit vehicle charging.
The case was dismissed without prejudice on September 9, 2024 — 41 days after filing — by Judge Jennifer L. Hall. The dismissal was not on the merits. WiTricity left Section VIII of the civil cover sheet blank, failing to disclose a materially related case (WiTricity v. Momentum Dynamics Corp., No. 20-1671) pending before Judge Goldberg and asserting the same ‘595 patent. Judge Hall found this violated Delaware Local Rule 3.1(b)(3) and that mere reassignment was insufficient deterrence.
The 41-day lifespan of the case is notable — even for procedural dismissals. The public record does not reveal whether the omission was inadvertent or strategic; however, Judge Hall explicitly noted WiTricity’s stated concern that reassignment to Judge Goldberg would trigger a stay. WiTricity retains the right to refile with a compliant cover sheet, meaning the substantive infringement dispute over the five patents remains unresolved and commercially alive.

Dismissed without prejudice: what the ruling means for both parties
Dismissal for Local Rule non-compliance — not a merits ruling
Judge Hall dismissed the case under the court’s inherent authority to enforce Delaware Local Rule 3.1(b)(3), which requires plaintiffs to identify related pending cases on the civil cover sheet. Because WiTricity asserted the same ‘595 patent in a 2020 case before Judge Goldberg, the omission was a clear violation. The court expressly stated that simple reassignment would be insufficient deterrence, making dismissal the chosen sanction.
Procedural — no merits adjudicationWiTricity can refile — but faces the shadow of a stayed case
A dismissal without prejudice means WiTricity is not barred from refiling its infringement claims. However, any refiled complaint must disclose the Momentum Dynamics case. This likely means reassignment to Judge Goldberg — and, as WiTricity itself anticipated, a probable motion by defendants to stay the new case pending resolution of the earlier proceedings. The substantive patent claims remain live but the litigation path is now more constrained.
Refile permitted — stay risk elevatedIdeanomics and WAVE gain time but no permanent shield
The dismissal without prejudice offers Ideanomics and WAVE a temporary reprieve rather than a definitive win. No invalidity or non-infringement ruling was made. If WiTricity refiles, defendants are well-positioned to seek a stay before Judge Goldberg, potentially linking this dispute to the stayed Momentum Dynamics proceedings. This may materially delay substantive litigation, giving WAVE commercial breathing room on its inductive charging product line.
No merits win — stay strategy availableWireless EV charging IP uncertainty persists across the sector
WiTricity’s five-patent portfolio targeting the WAVE system signals aggressive enforcement across the wireless inductive charging space for electric vehicles. The dismissal resolves nothing technically — the patents remain in force and the accused product is still on the market. Competitors and fleet operators commercialising wireless EV charging should treat this case as an indicator of WiTricity’s enforcement intent, not a clearance event. Freedom-to-operate analysis against WiTricity’s portfolio is advisable.

Official order — verbatim text
Judge Hall’s order is explicitly a sanctions-based procedural dismissal, not a ruling on infringement, validity, or claim scope. The language — ‘DISMISSED without prejudice to refile’ — preserves all substantive claims while penalising the procedural violation. The order’s pointed reference to WiTricity’s own stated concern about a stay before Judge Goldberg suggests the court viewed the cover sheet omission as potentially tactical rather than inadvertent, reinforcing the decision to go beyond mere reassignment.
US9184595 — Wireless Power Transfer for Electric Vehicle Charging
US9184595B2, filed via application US12/705582, is a foundational patent in WiTricity’s wireless power transfer portfolio covering inductive resonance-based charging for electric vehicles. It sits alongside four companion patents spanning application dates from 2009 (US12/639972) through 2017 (US15/793198), together forming a layered IP stack covering coil geometry, resonator design, transmitter-receiver configurations, and power management for contactless EV charging systems.
WiTricity’s portfolio has been asserted across multiple defendants in Delaware, signalling an enforcement strategy aimed at establishing licensing dominance in the wireless EV charging sector. For competitors, fleet operators, and infrastructure providers commercialising inductive charging, these patents represent a persistent infringement risk. The ‘595 patent in particular has been in active litigation since 2020, suggesting WiTricity views it as a core claim anchor in its enforcement programme.
Should you run an FTO against WiTricity’s wireless EV charging portfolio?
Any company developing, manufacturing, or deploying wireless inductive charging hardware for electric vehicles — whether for passenger, fleet, or transit applications — should assess exposure to WiTricity’s five-patent cluster. The WAVE case demonstrates WiTricity’s willingness to assert multiple patents simultaneously against commercial charging products. The dismissal without prejudice means no invalidity or non-infringement findings exist to rely on.

What this case signals for the wireless EV charging IP landscape
A procedural dismissal in 41 days should not obscure the commercial reality: WiTricity is actively enforcing a broad wireless charging portfolio.
Civil cover sheet compliance is a substantive risk in Delaware patent practice
Judge Hall’s ruling makes clear that Delaware courts will sanction — not merely reassign — plaintiffs who omit related cases. Any practitioner filing a patent suit in Delaware where the same patent has been previously asserted must disclose that case in Section VIII, even if the earlier case is stayed or involves different defendants.
WiTricity’s refile will almost certainly land before Judge Goldberg
With mandatory disclosure of the Momentum Dynamics case, reassignment is effectively unavoidable. Judge Goldberg’s stayed case creates a litigation overhang for the entire WiTricity-vs-WAVE dispute. Defendants will likely seek to extend the stay, making the timeline for any infringement trial highly uncertain and potentially years away.
WiTricity v Ideanomics — key questions answered
The case was dismissed without prejudice by Judge Hall on September 9, 2024 because WiTricity failed to disclose a related pending case (WiTricity v. Momentum Dynamics, No. 20-1671) on the civil cover sheet, violating Delaware Local Rule 3.1(b)(3). Both cases asserted US9184595. The court found sanctions beyond reassignment were warranted.
Yes. The dismissal was expressly without prejudice, meaning WiTricity retains the right to refile. Any refiled complaint must comply with Local Rule 3.1 and disclose the Momentum Dynamics related case, which will likely result in assignment to Judge Goldberg and a probable motion to stay the new proceedings.
WiTricity asserted five U.S. patents: US9184595B2, US9843228B2, US9450422B2, US10141790B2, and US8400021B2. All relate to wireless inductive power transfer technology for electric vehicle charging. The accused product was the WAVE by Ideanomics wireless inductive charging system.
Delaware Local Rule 3.1(b)(3) requires plaintiffs to identify on the civil cover sheet any related civil action involving the same patent. WiTricity left Section VIII blank despite having filed a prior case asserting US9184595 before Judge Goldberg. Judge Hall ruled the omission violated the rule and dismissed the case as a deterrent sanction rather than simply reassigning it.
WiTricity v. Momentum Dynamics Corp. (No. 20-1671, D. Del.), filed December 9, 2020 and assigned to Judge Mitchell S. Goldberg, was stayed as of the September 2024 order. It asserts multiple patents including US9184595. That case is the more significant bellwether for claim construction and validity rulings affecting WiTricity’s wireless charging portfolio.
