Plum Laboratories v. RCN Communications: Pop-up Network Kit Patent Dispute Ends With Prejudice
Plum Laboratories, Inc. brought a four-patent infringement action against RCN Communications, LLC and RTECH Solutions, LLC in Tennessee’s Eastern District over Pop-up Network Kit technology. The parties jointly stipulated to dismiss all claims and counterclaims with prejudice under Rule 41(a)(1)(A)(ii) — closing the case in 300 days.
Four-Patent Pop-up Network Kit Dispute Settled Quietly in Under a Year
Plum Laboratories, Inc. filed this infringement action on 8 November 2023 in the U.S. District Court for the Eastern District of Tennessee, targeting RCN Communications, LLC and its affiliate RTECH Solutions, LLC. The complaint asserted four issued U.S. patents — US10003124B2, US10381714B1, US10249938B1, and US10651545B2 — all directed to Pop-up Network Kit (PNK) technology. Plum was represented by Bradley Arant Boult Cummings LLP; defendants retained Neal Gerber & Eisenberg LLP alongside individual counsel Charles Shih.
The case closed on 3 September 2024 via a joint stipulation of dismissal with prejudice filed under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). All claims brought by Plum and all counterclaims asserted by RCN and RTECH were dismissed with prejudice simultaneously, meaning neither side can re-litigate the same claims in any future proceeding. This bilateral finality is a hallmark of negotiated resolution, strongly suggesting the parties reached a confidential settlement before filing the stipulation.
The 300-day duration is notably swift for a four-patent infringement matter, suggesting that substantive claim construction or expert discovery phases were likely abbreviated or bypassed entirely. The public record does not disclose any licensing terms, financial consideration, or ongoing business arrangement between the parties. The with-prejudice dismissal of RCN’s counterclaims — which in patent cases typically include invalidity defences — means those challenges to Plum’s patents are also extinguished as between these parties, which may have commercial value for Plum’s enforcement posture.

Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41(a)(1)(A)(ii) — parties jointly end the case permanently
A joint stipulation under Fed. R. Civ. P. 41(a)(1)(A)(ii) requires the written consent of all parties and takes effect immediately upon filing — no court order is needed. The ‘with prejudice’ designation means the dismissal operates as a final adjudication on the merits, permanently barring Plum from re-filing the same infringement claims against RCN and RTECH on these four patents.
Bilateral, court-order-free finalityPlum’s patents survive — but enforcement against RCN is closed
Dismissal with prejudice extinguishes Plum’s claims against RCN and RTECH on these specific patents. However, the patents themselves remain in force and fully enforceable against the rest of the market. Crucially, RCN’s counterclaims — which in patent cases almost always include invalidity arguments — were also dismissed with prejudice, meaning RCN cannot later challenge the validity of these patents in this dispute. That outcome is consistent with a negotiated resolution that preserved Plum’s IP assets.
Patents intact; RCN-specific enforcement closedRCN exits litigation but cannot revisit invalidity claims
For RCN Communications and RTECH Solutions, the with-prejudice dismissal provides certainty — Plum cannot re-sue them on the same four patents. However, the bilateral nature of the stipulation means RCN also gave up its counterclaims, likely including any invalidity or non-infringement arguments it had developed. This trade-off is typical in settlements: defendants accept some IP risk in exchange for litigation finality and cost certainty.
Litigation finality; counterclaims waivedPlum’s PNK patent portfolio remains a live enforcement threat to others
Because the four PNK patents were not invalidated or limited in scope, any third party deploying similar Pop-up Network Kit technology should treat this outcome as a signal that the portfolio is actively enforced. The rapid settlement — before claim construction — means no public narrowing of claim scope occurred, leaving the patents’ full breadth intact. Companies in the portable or deployable network infrastructure space should assess their freedom-to-operate exposure against these four US patents.

Official order — verbatim text
The stipulation invokes Rule 41(a)(1)(A)(ii), which requires all parties’ written consent and delivers immediate dismissal without a court order. The with-prejudice designation on both claims and counterclaims is legally significant: it operates as a final judgment on the merits for purposes of res judicata, preventing either party from relitigating these specific infringement or invalidity positions. The bilateral scope — covering Plum’s infringement claims and RCN’s defensive counterclaims — is consistent with a fully negotiated exit rather than a unilateral concession by either side.
US10003124B2 and three related patents — Pop-up Network Kit technology
The four asserted patents — US10003124B2, US10381714B1, US10249938B1, and US10651545B2 — share a common technological lineage in Pop-up Network Kit systems, covering rapid-deployment portable network infrastructure. The application dates, derived from the corrected application numbers (filed across 2017–2019), suggest a coordinated continuation filing strategy designed to build layered claim coverage around the PNK product family. The patents sit within the wireless communications and network infrastructure domain.
For competitors and integrators in the portable or emergency-deployment network space, a four-patent stack of this kind is strategically significant. Each patent in a continuation family typically covers a distinct aspect of the system — hardware configuration, antenna design, deployment methods, or power management — making it difficult to engineer around any single patent without potentially infringing the others. Plum’s willingness to assert all four patents simultaneously signals an aggressive enforcement posture that warrants ongoing portfolio monitoring.
Should you run an FTO against Plum’s four PNK patents?
Any R&D team designing portable, modular, or rapid-deployment network kit products should treat Plum’s four-patent PNK portfolio as a live risk. The patents were asserted against a commercial defendant and survived to a negotiated resolution with no public scope limitation. Companies developing deployable wireless infrastructure — whether for emergency response, event connectivity, military, or enterprise temporary deployment — should conduct a formal freedom-to-operate analysis before commercialisation.
PatSnap Eureka’s FTO Search Agent can map your product specifications against the claim sets of US10003124B2, US10381714B1, US10249938B1, and US10651545B2 simultaneously, flagging overlapping claim elements and identifying prior art that could support a design-around or invalidity position. Given the absence of any claim construction order in this case, understanding the full potential claim scope is essential before bringing a PNK-category product to market.

What this case signals for the portable network infrastructure IP landscape
A rapid, bilateral dismissal with prejudice on four patents suggests negotiated resolution — and keeps Plum’s PNK portfolio fully armed for future enforcement.
No claim construction means full patent breadth is preserved for future targets
Because the case resolved before any Markman hearing or claim construction order, the scope of Plum’s four PNK patents was never publicly narrowed. Any company building or deploying pop-up or rapid-deployment network kits faces the same undiminished infringement risk that prompted this filing. An FTO analysis against US10003124B2, US10381714B1, US10249938B1, and US10651545B2 should be a priority for product teams.
Bilateral with-prejudice dismissal strongly signals a confidential settlement
Joint stipulations that dismiss both claims and counterclaims with prejudice are a recognised fingerprint of negotiated resolution. The public record is silent on financial terms or licensing arrangements. Competitors and potential licensees should note that Plum has now demonstrated willingness to litigate and resolve — a pattern that typically precedes further enforcement campaigns in adjacent market segments.
Plum v Rcn — key questions answered
The joint stipulation under Rule 41(a)(1)(A)(ii) dismisses all of Plum’s infringement claims and all of RCN’s counterclaims with prejudice. ‘With prejudice’ means the dismissal operates as a final judgment — neither party can re-file the same claims or counterclaims against each other in any future proceeding. Plum’s four PNK patents remain valid and enforceable against third parties.
Plum Laboratories asserted four U.S. patents: US10003124B2, US10381714B1, US10249938B1, and US10651545B2. All four relate to Pop-up Network Kit (PNK) technology. The patents derive from application numbers filed between 2017 and 2019, suggesting a deliberate continuation-filing strategy to build layered coverage around the PNK product family.
The public record does not confirm a financial settlement, but the bilateral dismissal with prejudice of both claims and counterclaims under Rule 41(a)(1)(A)(ii) is strongly consistent with a negotiated resolution. The terms of any agreement — including licensing fees, royalties, or business arrangements — are not disclosed in the court record.
No claim construction order appears in the public record. The case resolved in approximately 300 days — before the typical timeframe for a Markman hearing in a four-patent district court case. This means the scope of the asserted claims was never publicly narrowed, and Plum’s PNK patents retain their full potential claim breadth as issued.
Pop-up Network Kits are portable, rapidly-deployable wireless network systems designed for quick setup in locations lacking fixed infrastructure — such as emergency response, military, event, or enterprise temporary deployment scenarios. Plum’s four-patent stack covering PNK technology is commercially significant because it creates layered IP protection that is difficult to design around, and the successful assertion against RCN signals active enforcement intent across the sector.
