Bright Data v. BI Science: Federal Circuit Appeal on Internet Proxy Patents
Bright Data, Ltd. brought an infringement action against BI Science (2009), Ltd. asserting two US patents covering systems and methods for improving internet communication via intermediate nodes. The appeal reached the Court of Appeals for the Federal Circuit and closed after 923 days. The recorded basis of termination is Appeal Dismissed; the docket order states AFFIRMED.
Federal Circuit closes Bright Data v. BI Science after 923-day appeal
Bright Data, Ltd. initiated an infringement action against BI Science (2009), Ltd. asserting US9742866B2 and US9241044B2 — both directed to systems and methods for improving internet communication by using intermediate nodes. The appeal was docketed at the Court of Appeals for the Federal Circuit as Case No. 21-1667, filed on 18 February 2021 and closed on 30 August 2023, spanning 923 days.
The recorded basis of termination is Appeal Dismissed. The docket order states: 'THIS CAUSE having been considered, it is ORDERED AND ADJUDGED: AFFIRMED.' These two characterisations differ; the specific terms and procedural mechanism underlying their coexistence are not disclosed in the available record, and no reconciliation is offered here.
The 923-day duration is consistent with complex Federal Circuit proceedings involving multi-patent infringement disputes in the internet infrastructure domain. What drove the precise resolution — and what, if anything, was agreed between the parties — is not disclosed in the publicly available record.

923 days — a multi-year Federal Circuit appeal in an internet infrastructure patent dispute
US9742866B2 & US9241044B2 — Internet Communication via Intermediate Nodes
Any company building or deploying products that route internet traffic through intermediate nodes — including proxy servers, CDN edge nodes, VPN relay architectures, or web data collection tools — faces potential exposure to Bright Data's asserted patent family. The absence of a definitive appellate merits ruling in this proceeding means the claim scope has not been authoritatively narrowed or invalidated at this level.
Official order — verbatim text
The docket order states 'AFFIRMED' following consideration of the cause; however, the recorded basis of termination is Appeal Dismissed. These two characterisations are reported as-is from the available record. The specific procedural basis for their coexistence is not disclosed, and no merits-level reconciliation is offered here.
Appeal Dismissed: what the Federal Circuit's recorded outcome means
Appeal Dismissed at the Federal Circuit — no merits ruling on record
The recorded basis of termination is Appeal Dismissed, indicating the appeal did not proceed to a full merits adjudication at this level. Separately, the docket order text states AFFIRMED. These two characterisations are reported as-is from the available record; the specific procedural basis for their coexistence is not disclosed.
Recorded: Appeal DismissedBright Data's appellate position ends without a disclosed merits win
With the appeal recorded as dismissed, Bright Data does not gain a confirmed appellate ruling on the infringement merits through this proceeding as characterised in the termination record. The enforceability status of US9742866B2 and US9241044B2 going forward is not definitively resolved in the publicly available record.
Patent status: unresolved on recordBI Science avoids a recorded adverse appellate merits ruling
As the basis of termination is Appeal Dismissed rather than a full merits ruling against BI Science, the defendant is not recorded as having lost at the Federal Circuit level. Whether any arrangement between the parties accounts for this outcome is not disclosed in the available record.
No adverse merits ruling recordedIntermediate-node proxy patents remain a live enforcement risk in this sector
The two asserted patents — covering systems and methods for improving internet communication via intermediate nodes — remain relevant to companies operating in the internet proxy, CDN, and data-routing sectors. The absence of a publicly disclosed merits ruling means the claim scope of these patents has not been definitively adjudicated at appellate level in this proceeding.

R&D signals in the internet proxy and intermediate-node patent space
Forward-looking patent intelligence derived from Bright Data v. BI Science — surfacing filing trends, portfolio dynamics, and white-space opportunities in internet routing and proxy technology.
Bright Data's intermediate-node patent family beyond the two asserted patents
Bright Data's enforcement of US9742866B2 and US9241044B2 at the Federal Circuit suggests these are core assets within a broader filing strategy around proxy and internet routing technology. Mapping the full continuation and divisional family around application nos. US14/930894 and US14/468836 may reveal additional claim coverage relevant to proxy infrastructure product teams.
Bright Data portfolio — proxy IPFiling trends in intermediate-node and proxy routing systems since 2015
The application dates underlying US9742866B2 and US9241044B2 place them in the mid-2010s wave of internet infrastructure patenting. Tracking subsequent filing activity in the intermediate-node, residential proxy, and edge-routing space can reveal whether patent density is increasing — and where competitors are staking new claim territory adjacent to Bright Data's coverage.
Proxy routing — filing trendsBI Science's patent position in internet communication technology
BI Science (2009), Ltd. defended a Federal Circuit infringement action on intermediate-node internet communication patents, represented by Sterne, Kessler — suggesting a considered IP defence posture. Examining BI Science's own filing activity and cited prior art in this proceeding may reveal defensive patent strategies relevant to others operating in the same technical space.
BI Science — defensive IPAdjacent innovation opportunities near Bright Data's claimed proxy architecture
The claim space around improving internet communication via intermediate nodes has become contested territory. Adjacent white-space areas — such as privacy-preserving relay protocols, decentralised node selection mechanisms, and encrypted intermediate routing for IoT — may offer R&D teams room to innovate without directly overlapping the claim boundaries of the asserted patents.

What this case signals for the internet proxy and routing IP landscape
Two foundational intermediate-node patents litigated at the Federal Circuit — with an outcome that leaves claim scope unresolved in the public record.
Intermediate-node proxy patents are actively enforced at appellate level
Bright Data's willingness to pursue a 923-day Federal Circuit appeal on US9742866B2 and US9241044B2 signals that these patents are considered high-value enforcement assets. Companies in the proxy, VPN, CDN, and data-routing sectors should treat these patents as live litigation risk and monitor Bright Data's portfolio activity.
Ambiguous termination records create uncertainty for third-party FTO analysis
The divergence between the recorded basis of termination (Appeal Dismissed) and the docket order text (AFFIRMED) means third parties cannot rely on a clean appellate merits ruling to inform freedom-to-operate decisions. Independent claim-scope analysis of US9742866B2 and US9241044B2 remains advisable for any product that routes traffic through intermediate nodes.
Bright v BI — key questions answered
The recorded basis of termination is Appeal Dismissed. The docket order separately states 'THIS CAUSE having been considered, it is ORDERED AND ADJUDGED: AFFIRMED.' These two characterisations are reported as-is; the specific procedural basis for their coexistence is not disclosed in the available public record.
Bright Data asserted two US patents: US9742866B2 (application no. US14/930894) and US9241044B2 (application no. US14/468836). Both cover systems and methods for improving internet communication by using intermediate nodes.
The appeal was filed on 18 February 2021 and closed on 30 August 2023, spanning 923 days — consistent with a multi-year Federal Circuit proceeding in a complex internet infrastructure patent dispute.
Both patents are directed to systems and methods for improving internet communication by using intermediate nodes — a technical architecture relevant to proxy networks, content delivery infrastructure, anonymised routing, and web data collection platforms.
Yes. The absence of a definitive appellate merits ruling on the claim scope of US9742866B2 and US9241044B2 in this proceeding means these patents remain a live risk for any product routing internet traffic through intermediate nodes. An independent FTO analysis against the claim families of both patents is advisable.
