TP-Link Systems v. InnoMemory: AC1200 Router Patent Action Resolved in 44 Days
TP-Link Systems Inc. brought a patent infringement action against InnoMemory, LLC in the Southern District of New York over the AC1200 wireless router, asserting US7057960B1. The case closed just 44 days after filing via a stipulated dismissal — TP-Link’s claims dismissed without prejudice, InnoMemory’s counterclaims dismissed with prejudice, each side bearing its own costs.
A 44-day stipulated exit: asymmetric dismissal terms hint at leverage
On 8 October 2024, TP-Link Systems Inc. filed an infringement action against InnoMemory, LLC in the U.S. District Court for the Southern District of New York, assigned to Judge Margaret M. Garnett. The dispute centred on US7057960B1 and its alleged relevance to TP-Link’s AC1200 wireless router product. TP-Link was represented by WilmerHale, a prominent IP litigation firm, while InnoMemory retained DNL Zito Castellano and Rabicoff Law LLC — a pairing frequently associated with non-practising entity assertions.
The case closed on 21 November 2024, just 44 days after filing, via a stipulated dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). The asymmetric terms are notable: TP-Link’s affirmative claims were dismissed without prejudice — preserving TP-Link’s right to refile — while InnoMemory’s counterclaims were dismissed with prejudice, foreclosing InnoMemory from reasserting those specific claims. Neither side was awarded costs, expenses, or attorney’s fees.
The speed of resolution — 44 days — suggests that substantive litigation was never meaningfully engaged. Cases of this duration typically resolve through early commercial negotiation or a recognition by one or both parties that continued litigation carries disproportionate risk or cost. The public record does not disclose whether any licence, payment, or other commercial arrangement was reached. The without-prejudice dismissal of TP-Link’s claims means the patent’s validity and infringement were never adjudicated, and TP-Link retains the theoretical ability to refile.

Asymmetric Rule 41 exit: what the stipulated dismissal means for both sides
Rule 41(a)(1)(A)(ii) stipulated dismissal explained
A Rule 41(a)(1)(A)(ii) dismissal requires both parties’ signatures, distinguishing it from a unilateral plaintiff withdrawal. Here, the parties negotiated asymmetric terms: TP-Link’s claims exit without prejudice (refiling permitted), while InnoMemory’s counterclaims exit with prejudice (permanently barred). This structure is consistent with a negotiated resolution rather than a straightforward walk-away.
Stipulated — bilateral agreementWithout prejudice vs. with prejudice: not the same outcome
TP-Link’s claims leaving without prejudice means no adjudication on the merits — the patent’s validity and alleged infringement remain open legal questions, and TP-Link could theoretically refile. InnoMemory’s counterclaims leaving with prejudice means those specific defences or counter-assertions cannot be raised again. The public record is silent on whether any commercial arrangement underpins this asymmetry.
Merits never adjudicatedInnoMemory’s counterclaims permanently barred
The with-prejudice disposal of InnoMemory’s counterclaims is a meaningful concession. It suggests InnoMemory either lacked confidence in its counter-assertions or agreed to their permanent waiver as part of a broader negotiated resolution. TP-Link, by contrast, exits with its patent enforcement position intact — US7057960B1 remains unlitigated and potentially enforceable against others.
InnoMemory counterclaims closed44-day close signals pre-litigation negotiation dynamics
Cases resolved within 44 days of filing rarely see substantive motion practice. This timeline, combined with WilmerHale’s involvement and the asymmetric dismissal structure, suggests the parties may have had pre-filing or early-stage commercial discussions. For the wireless networking IP market, the case leaves US7057960B1 unadjudicated — a risk that competitors and product teams should factor into FTO analysis.

Official order — verbatim text
The stipulated dismissal language — negotiated and signed by both parties under Rule 41(a)(1)(A)(ii) — creates a deliberate asymmetry: TP-Link’s infringement claims survive in the sense that they may be refiled, while InnoMemory’s counterclaims are permanently extinguished. This phrasing reflects a bilateral compromise rather than a unilateral retreat. No merits determination was made on US7057960B1’s validity or its application to the AC1200 router, leaving the substantive patent questions entirely open.
US7057960B1 — Wireless networking data-path technology
US7057960B1 was filed under application number US10/629667 and issued as a US granted patent. The patent sits within the wireless networking domain, with its claims relevant to data-path or memory management functionality in wireless router hardware — the technology area directly implicated by TP-Link’s AC1200 product line. The ‘960 patent was never subjected to a merits ruling in this litigation, leaving its claim scope and validity formally uncontested by any court.
For the wireless router and networking hardware sector, an unlitigated but actively asserted patent of this type represents a latent risk. InnoMemory’s willingness to assert it against a major manufacturer like TP-Link — and TP-Link’s decision to retain WilmerHale rather than settle quietly — suggests the patent is viewed as commercially significant by both sides. Competitors and adjacent product developers in the AC-class wireless router space should assess their exposure to US7057960B1’s claims before launching or iterating products.
Should your team run an FTO against US7057960B1?
Any company designing, manufacturing, or distributing AC-class or similar wireless routers — particularly those with data-path or memory management architectures that could read on US7057960B1’s claims — should conduct a freedom-to-operate analysis. The patent was asserted against a commercial product and dismissed without prejudice, meaning enforcement risk has not been legally resolved. R&D teams preparing new wireless router generations should not treat this case’s closure as a green light.
PatSnap Eureka’s FTO Search Agent allows IP and product teams to map US7057960B1’s independent claims against their product architecture, identify prior art that may limit the patent’s enforceable scope, and monitor for any continuation or related applications that could extend the assertion risk. Running an automated FTO on this patent family before product launch is a practical risk-management step given the unresolved litigation posture.

What this case signals for the wireless networking IP landscape
A rapid stipulated exit with asymmetric terms is rarely without strategic purpose. Here is what practitioners and product teams should note.
US7057960B1 remains unadjudicated — FTO exposure persists
Because TP-Link’s claims were dismissed without prejudice, no court has ruled on whether US7057960B1 is valid or infringed by the AC1200 router. Companies in the wireless router and networking hardware space should treat this patent as an active FTO concern until a merits ruling or IPR outcome changes its status.
Asymmetric dismissal terms are a negotiating signal worth reading
When plaintiff claims exit without prejudice but defendant counterclaims exit with prejudice, it typically suggests the defendant made a concession — whether substantive or commercial. IP professionals monitoring InnoMemory’s assertion activity should note this pattern when assessing future enforcement risk from similar entities.
TP-Link v InnoMemory — key questions answered
TP-Link Systems asserted US7057960B1 (application number US10/629667) in its infringement action against InnoMemory, LLC. The patent covers wireless networking technology and was alleged to be relevant to TP-Link’s AC1200 wireless router. No merits determination was made before the case was dismissed.
The asymmetric dismissal under Rule 41(a)(1)(A)(ii) was stipulated by both parties. TP-Link’s claims exiting without prejudice means it retains the right to refile the infringement action. InnoMemory’s counterclaims exiting with prejudice means those specific counter-assertions are permanently barred. The public record does not disclose the commercial terms, if any, that drove this arrangement.
The case closed in 44 days from filing on 8 October 2024 to dismissal on 21 November 2024. This timeline is well below the multi-year average for district court patent cases and suggests no substantive motion practice occurred. It is consistent with early commercial negotiation or a rapid assessment by both parties that continued litigation was not in their interest.
No. Because both parties’ claims were dismissed before any merits ruling, the validity and claim scope of US7057960B1 were never adjudicated. The patent remains a potentially enforceable asset. Companies in the wireless router hardware space should treat it as an active risk when conducting freedom-to-operate analysis.
