Encryptawave Technologies v. Foxconn: Infringement Action Dismissed With Prejudice
Encryptawave Technologies LLC asserted US7233664B2 — a wireless encryption patent — against Foxconn Technology Group in the Eastern District of Texas, targeting over 120 mobile computing and scanning products. The plaintiff voluntarily dismissed with prejudice after just 123 days, before Foxconn filed any answer or summary judgment motion, with each party bearing its own costs.
Early Exit: Encryption Patent Suit Ends Before Foxconn Responds
On June 21, 2024, Encryptawave Technologies LLC filed suit against Foxconn Technology Group in the Eastern District of Texas before Judge Sean D. Jordan, asserting infringement of US7233664B2 — a patent covering encrypted wireless communications filed under application number US10/448989. The complaint targeted an unusually broad product portfolio spanning over 120 SKUs, including Honeywell-branded mobile computers, handheld scanners, and industrial data terminals such as the CK75, EDA51, CT45, and Dolphin series devices.
The case closed on October 22, 2024, just 123 days after filing. Encryptawave filed a Notice of Voluntary Dismissal with Prejudice under Federal Rule of Civil Procedure 41(a)(1), which permits a plaintiff to dismiss unilaterally before the defendant has served an answer or a motion for summary judgment. Dismissal with prejudice is legally significant: it operates as a final adjudication on the merits, permanently barring Encryptawave from reasserting the same claims against Foxconn under this patent.
The resolution timeline — well under six months — suggests the parties likely reached a private accommodation, though no settlement terms appear on the public docket. The equal cost-bearing provision is consistent with a negotiated resolution rather than capitulation by either side. What drove the withdrawal remains unknown: possibilities include a licensing arrangement, a freedom-to-operate concession, or a reassessment of claim scope following pre-answer communications. No invalidity or non-infringement finding was made by the court.

Dismissed with prejudice: what Rule 41(a)(1) means for both parties
Rule 41(a)(1): Plaintiff’s right to exit before defendant responds
Under FRCP Rule 41(a)(1), a plaintiff may dismiss an action without a court order by filing a notice of dismissal before the defendant serves an answer or a motion for summary judgment. Here, Encryptawave exercised that right. The ‘with prejudice’ designation converts this voluntary act into a final judgment on the merits — as binding as a court ruling — foreclosing any future lawsuit by Encryptawave on the same claims against Foxconn.
Permanent bar on re-filingEncryptawave permanently forfeits its claims against Foxconn
By dismissing with prejudice, Encryptawave surrendered its right to reassert US7233664B2 infringement claims against Foxconn in any future proceeding. This is a material concession regardless of any private agreement reached. The patent itself remains in force and may still be asserted against other defendants, but Foxconn’s products are now shielded from this specific plaintiff under this patent.
Claims extinguished vs. FoxconnFoxconn exits without admitting infringement or invalidity
Foxconn achieved dismissal without filing an answer, engaging in discovery, or making any merits concession. No finding of infringement, validity, or damages was entered. The equal cost-bearing term means Foxconn recovered none of its defence costs. The outcome provides no precedential guidance on whether the accused products actually infringe US7233664B2 — Foxconn’s position remains legally untested but commercially protected.
No merits ruling; costs unrecovered120+ product SKUs cleared — but patent remains active against others
The dismissal effectively clears Foxconn’s extensive mobile computing and industrial scanning portfolio from this specific dispute. However, US7233664B2 remains a live asset for Encryptawave against other manufacturers in the wireless encrypted communications space. Companies operating adjacent product lines — particularly those with Wi-Fi or cellular-enabled handheld devices — should monitor this patent’s enforcement posture carefully.

Official order — verbatim text
The dismissal notice invokes Rule 41(a)(1) in precise terms, confirming no court order was required — meaning Foxconn had not yet served an answer or summary judgment motion. The ‘with prejudice’ designation is the operative legal fact: it strips Encryptawave of any future cause of action against Foxconn on these claims. The cost-neutrality clause is notable; it suggests a negotiated exit rather than a unilateral concession, though no settlement agreement appears in the public record. No merits findings were made by the court.
US7233664B2 — Wireless Encrypted Communication Technology
US7233664B2 was filed under application number US10/448989 and covers encrypted wireless communication methods and systems — technology foundational to secure data transmission in mobile computing environments. The patent sits at the intersection of wireless networking and data security, domains that have become critical infrastructure for enterprise mobility, logistics, and industrial scanning applications. Its filing date places it in an era when Wi-Fi and early cellular data integration into handheld devices was emerging as a commercial priority.
The commercial significance of this patent is amplified by its breadth: Encryptawave’s product list spans enterprise-grade handhelds, vehicle-mounted computers, and industrial scanners — device categories where encrypted wireless communication is now a baseline requirement. Any manufacturer shipping Wi-Fi or cellular-enabled mobile data devices into logistics, healthcare, or manufacturing environments faces potential exposure. The patent’s continued validity following this case’s dismissal without a merits ruling means it remains an active enforcement risk across the sector.
Should you run an FTO against US7233664B2?
Any R&D or product team developing Wi-Fi or cellular-enabled handheld computers, industrial scanners, mobile data terminals, or vehicle-mounted computers should treat US7233664B2 as a priority FTO target. This case demonstrates that Encryptawave is actively asserting the patent against large-volume device manufacturers — and the breadth of the accused product list suggests the claims are being read expansively. A proactive FTO assessment is materially lower-cost than reactive litigation defence in E.D. Texas.

What this case signals for the wireless encryption IP landscape
A rapid exit before any defence filing typically signals leverage calculus shifted — here is what practitioners should take away.
Pre-answer dismissals in E.D. Texas often mask private licensing activity
When a plaintiff voluntarily dismisses with prejudice before the defendant even answers, the most commercially rational explanation is a licensing arrangement or covenant not to sue. Patent practitioners advising clients in the wireless encryption and mobile device sector should treat this pattern as a signal to audit their own exposure to US7233664B2 before Encryptawave targets their products.
US7233664B2 remains enforceable — the product list signals claim breadth
Encryptawave’s complaint named over 120 distinct product SKUs across multiple device categories, suggesting broad claim interpretation of the encryption patent. R&D and product teams developing Wi-Fi or cellular-enabled industrial handhelds, mobile computers, or scanning devices should conduct an FTO assessment against this patent before product launch or market entry.
Encryptawave v Foxconn — key questions answered
The dismissal with prejudice under Rule 41(a)(1) operates as a final adjudication on the merits. Encryptawave permanently forfeited its right to sue Foxconn again under US7233664B2 on these claims. No court ruling on infringement, validity, or damages was issued — the outcome reflects the plaintiff’s unilateral decision to exit, not a finding in Foxconn’s favour.
A 123-day resolution before any defence filing strongly suggests the parties reached a private arrangement, potentially a licensing deal or covenant not to sue. Under Rule 41(a)(1), dismissal is available before the defendant serves an answer or summary judgment motion, giving plaintiffs a narrow window for unilateral exit. The equal cost-bearing clause is consistent with a negotiated resolution rather than a unilateral capitulation.
Encryptawave’s complaint named over 120 product SKUs associated with Foxconn/Honeywell-branded mobile computers, handheld barcode scanners, vehicle-mounted terminals, and industrial data capture devices — including the CK75, CT45, EDA51, CN75, Dolphin 99EX, and VM series. The breadth of the accused product list suggests Encryptawave interpreted the patent’s wireless encryption claims broadly.
No. A dismissal with prejudice in this case only bars Encryptawave from suing Foxconn again on the same claims. The patent itself remains in full force and effect. No court made any finding as to validity or infringement. Encryptawave retains the right to assert US7233664B2 against any other manufacturer or seller of allegedly infringing products.
A § 285 exceptional case fee motion requires a merits adjudication or, in some circuits, a finding that the case was objectively baseless. Here, dismissal occurred before Foxconn filed any responsive pleading, leaving no merits record. The equal cost-bearing term in the dismissal notice suggests both parties accepted their own costs, effectively precluding a fee dispute — though this was a negotiated term, not a court ruling.
