Rich Media Club v. ResearchGate: Three-Patent Ad-Tech Dispute Ends With Prejudice
Rich Media Club, LLC filed suit against academic networking platform ResearchGate GmbH in the Eastern District of Texas, asserting three US patents covering rich media online advertising technology. The parties jointly stipulated to dismissal with prejudice after 429 days, each bearing their own costs and attorneys’ fees.
Ad-Tech NPE Targets Academic Platform in E.D. Texas Patent Assertion
On August 8, 2023, Rich Media Club, LLC — a non-practising entity holding a portfolio of rich media advertising patents — filed an infringement action against ResearchGate GmbH, the Berlin-based academic social network, in the Eastern District of Texas before Judge Rodney Gilstrap. The complaint centred on ResearchGate’s website researchgate.net and alleged infringement of three US patents: US11631115B1, US11468453B2, and US11443329B2, all directed at rich media digital advertising methods and systems.
The case closed on October 10, 2024, when the parties filed a Joint Stipulation of Dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). The court acknowledged and accepted the stipulation, dismissing all claims between the parties with prejudice. Crucially, each side agreed to bear its own costs and attorneys’ fees, meaning no monetary award was entered on the public record. A dismissal with prejudice extinguishes the plaintiff’s right to re-assert the same claims against ResearchGate on these patents.
At 429 days, the case ran longer than a swift pre-answer settlement but closed well before any trial setting, consistent with a negotiated resolution reached during or after claim construction briefing stages. The mutual cost-bearing arrangement and the absence of any public damages figure suggest the parties reached a confidential resolution — potentially a licence — without litigating to judgment. The precise commercial terms, if any, remain unknown from the public record.

Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41(a)(1)(A)(ii) ends the case by agreement
A joint stipulation of dismissal under Rule 41(a)(1)(A)(ii) requires signatures from all parties who have appeared, making it self-executing upon filing — no court order is strictly required. The court here formally acknowledged and accepted the stipulation. The ‘with prejudice’ designation is the critical qualifier: it functions as a final adjudication on the merits, permanently barring Rich Media Club from reasserting these three patents against ResearchGate on the same claims.
Permanent bar on re-filingRich Media Club cannot re-sue ResearchGate on these patents
The with-prejudice dismissal permanently extinguishes Rich Media Club’s right to bring the same claims under US11631115B1, US11468453B2, and US11443329B2 against ResearchGate. However, dismissal with prejudice does not invalidate the patents themselves — Rich Media Club retains the right to assert these patents against other defendants. The mutual cost-bearing arrangement means no fee-shifting under 35 U.S.C. § 285 was triggered, preserving the case’s commercial confidentiality.
Patents remain enforceable vs. othersResearchGate secures permanent peace from this plaintiff on these patents
ResearchGate achieves litigation certainty: Rich Media Club is permanently barred from re-asserting these three patents against the researchgate.net platform on the claims raised here. The each-party-bears-own-costs arrangement avoided any public fee award, which would have required a finding of ‘exceptional case’ status. Whether ResearchGate secured a licence, made a payment, or simply outlasted the plaintiff’s resolve is not discernible from the public record — all three outcomes are consistent with this dismissal structure.
Permanent resolution for ResearchGateRich media ad-tech patents remain live enforcement tools
This dismissal does not resolve the underlying validity or scope of the three asserted patents — they survive as enforceable assets. Other online platforms displaying rich media advertising, particularly those with academic or professional audiences monetising via display and video ad units, should note that these patents remain in Rich Media Club’s portfolio. The E.D. Texas filing, Judge Gilstrap’s docket, and the NPE enforcement model all suggest continued assertion activity is plausible against other targets in the sector.

Official order — verbatim text
The court’s order tracks the standard Rule 41(a)(1)(A)(ii) joint stipulation framework precisely — the ‘ACKNOWLEDGES and ACCEPTS’ language confirms the court treated this as a ministerial closure rather than a contested motion. The with-prejudice designation is outcome-determinative: it forecloses any future action by Rich Media Club against ResearchGate on these specific claims, functioning as a final judgment on the merits for res judicata purposes. The explicit instruction that parties bear their own costs forecloses any subsequent fee motion, drawing a clean line under the dispute.
US11631115B1, US11468453B2 & US11443329B2 — Rich Media Advertising Technology
The three patents-in-suit — US11631115B1, US11468453B2, and US11443329B2 — are US utility patents directed at rich media digital advertising technology, covering methods and systems for delivering, managing, and interacting with advanced online ad formats beyond static display. Their application numbers (US17/964485, US17/316499, US17/317627) indicate filings in the 2021 timeframe, with all three issuing as granted patents. The close filing dates of US17/316499 and US17/317627 suggest a deliberate parallel continuation strategy to broaden claim coverage across related aspects of the same underlying technology.
For online platforms monetising through programmatic or direct-sold advertising — including professional networks, academic platforms, and content publishers — this patent family represents meaningful enforcement risk. Rich Media Club’s assertion against ResearchGate’s website demonstrates that even non-advertising-native platforms fall within scope if they serve rich media ad formats. The continuation structure means claim scope may vary across the three patents, potentially capturing different technical implementations of ad delivery, user interaction, or campaign tracking. Competitors and adjacent platforms should monitor Rich Media Club’s portfolio for further continuation filings.
Should your platform run an FTO against US11631115B1 and related patents?
Any development or product team operating a web platform that serves rich media advertising — including video, expandable, interactive, or programmatic ad units — should assess freedom-to-operate against this patent family. The fact that ResearchGate, a research networking site rather than a pure ad-tech company, was targeted confirms that incidental ad monetisation is sufficient to attract assertion. Platforms built on third-party ad servers or SSPs should also understand whether their vendor agreements include patent indemnification covering this family.
PatSnap Eureka’s FTO Search Agent can map your platform’s ad-serving architecture against the independent claims of US11631115B1, US11468453B2, and US11443329B2 simultaneously, identifying which technical features create the highest exposure. Eureka’s patent family visualisation also surfaces related continuations and pending applications from Rich Media Club’s portfolio, ensuring your FTO covers not just current patents but emerging claim coverage that could ripen into new assertions.

What this case signals for the ad-tech and online platform IP landscape
A with-prejudice dismissal after 14 months in E.D. Texas reveals characteristic NPE litigation dynamics in digital advertising patent enforcement.
E.D. Texas remains the preferred venue for ad-tech NPE assertions
Rich Media Club’s choice of Judge Gilstrap’s docket in the Eastern District of Texas is consistent with the court’s reputation for plaintiff-friendly scheduling and established patent litigation infrastructure. Online platforms generating revenue from digital advertising should treat any E.D. Texas filing as a signal to assess exposure promptly — the court’s pace can accelerate cost pressure before claim construction.
Mutual cost-bearing signals a commercially negotiated exit
When both parties agree to bear their own fees in a with-prejudice dismissal, it typically signals a negotiated resolution rather than a capitulation. The absence of fee-shifting means neither party pursued — or could sustain — an ‘exceptional case’ motion under § 285. For defendants in similar positions, this outcome suggests early engagement and settlement economics may be more commercially rational than full litigation.
Rich v ResearchGate — key questions answered
Dismissal with prejudice under Rule 41(a)(1)(A)(ii) permanently bars Rich Media Club from re-asserting US11631115B1, US11468453B2, and US11443329B2 against ResearchGate on the same claims. It operates as a final judgment on the merits for res judicata purposes. Importantly, it does not invalidate the patents — Rich Media Club may still assert them against other defendants.
Rich Media Club asserted three US patents: US11631115B1 (application US17/964485), US11468453B2 (application US17/316499), and US11443329B2 (application US17/317627). All three relate to rich media digital advertising technology and were asserted in connection with ResearchGate’s website researchgate.net.
The Eastern District of Texas — specifically Judge Gilstrap’s court — is a historically favoured venue for NPE patent assertions due to its established patent litigation procedures and plaintiff-friendly scheduling. The public record does not specify why Texas venue was chosen over a Delaware or California filing, but the choice is consistent with NPE enforcement patterns in digital advertising patent cases.
No. A joint stipulation of dismissal with prejudice does not constitute a ruling on patent validity or non-infringement. The three patents — US11631115B1, US11468453B2, and US11443329B2 — remain in force and enforceable against third parties. No claim construction order, invalidity ruling, or IPR institution arose from this case based on the available public record.
In patent cases, each-party-bears-own-costs language in a dismissal stipulation forecloses a subsequent motion for attorneys’ fees under 35 U.S.C. § 285, which requires a finding that the case was ‘exceptional.’ This arrangement is commonly used in confidential settlements to prevent either party from later claiming fee entitlement, and is consistent with — though does not confirm — a negotiated licence or payment reaching the parties outside the public record.
