Bright Data v. Data Company Technologies: Federal Circuit Affirms Unpatentability
Bright Data, Ltd. appealed the invalidation of three patents covering faster and more efficient data communication systems against The Data Company Technologies, Inc. The Federal Circuit affirmed the unpatentability finding across all three patents, closing a 750-day appellate battle.
Federal Circuit closes the door on Bright Data’s three-patent appeal
Bright Data, Ltd., the internet proxy and data-collection infrastructure company, filed this Federal Circuit appeal on 13 July 2023, challenging an underlying invalidity or cancellation determination covering three of its US patents: US10484510B2, US10257319B2, and US10069936B2. All three patents relate to systems providing faster and more efficient data communication — technology central to proxy-based web data collection. The respondent, The Data Company Technologies, Inc., successfully defended the unpatentability finding below.
On 1 August 2025, the Federal Circuit issued its order affirming the decision below in full. The court’s AFFIRMED disposition means it identified no reversible legal or factual error in the lower tribunal’s conclusion that the three asserted patents are unpatentable. For Bright Data, the affirmance extinguishes patent protection for these specific claims. For The Data Company Technologies, the ruling removes the litigation cloud these three patents created.
The 750-day duration suggests a substantive appellate record — consistent with cases involving multiple patents and complex patentability arguments. The basis of termination as ‘Unpatentable’ indicates the challenge succeeded on the merits rather than on procedural grounds. What the public record does not reveal is whether any claim narrowing, claim construction dispute, or specific § 101/§ 102/§ 103 ground drove the affirmance — those details would require review of the full opinion.

Federal Circuit affirms: what the unpatentability ruling means for both parties
Affirmance means no reversible error was found below
When the Federal Circuit affirms, it holds that the tribunal below committed no reversible legal or factual error. The lower unpatentability finding — covering all three Bright Data patents — is now final at this appellate level. The court did not substitute its own judgment; it confirmed the lower decision was legally sound. Bright Data’s claims are extinguished as a matter of patent law.
Appellate standard: no reversible errorBright Data loses enforceability on all three patent assets
With affirmance, US10484510B2, US10257319B2, and US10069936B2 are no longer enforceable. Bright Data cannot assert these patents in future litigation or licensing negotiations. The ruling effectively removes three data communication patents from its IP portfolio. Bright Data’s remaining option at the federal level would be a petition to the Supreme Court — a high bar with low grant rates for patent cases.
Patents unenforceable — appeal options narrowData Company Technologies secures a clean freedom-to-operate position
The affirmance confirms that The Data Company Technologies’ challenge to patentability succeeded at both the lower and appellate levels. The company now operates without the threat of infringement claims under these three patents. The Federal Circuit’s endorsement of the unpatentability finding also raises the bar for Bright Data reasserting similar claims through continuation or reissue proceedings.
FTO confirmed across all three patentsProxy and data infrastructure sector faces weakened patent landscape
The invalidation of three Bright Data data communication patents at the Federal Circuit suggests the proxy infrastructure space may face difficulty securing broad patent protection for systems-level data communication improvements. Competitors and new entrants in web data collection, residential proxy, and data pipeline technology should note that the unpatentability bar was upheld on appeal — consistent with a tightening judicial view of this patent class.

Official order — verbatim text
The Federal Circuit’s order — ‘THIS CAUSE having been considered, it is ORDERED AND ADJUDGED: AFFIRMED’ — is a merits affirmance, not a procedural disposition. The court reviewed the unpatentability finding under the applicable appellate standard, which for legal conclusions is de novo and for factual findings is substantial evidence. The terse AFFIRMED language, combined with the ‘Unpatentable’ basis of termination, confirms the lower tribunal’s invalidity determination was legally and factually sound across all three patents. Neither party obtained a partial remand or claim-by-claim carve-out on the available record.
US10484510B2, US10257319B2 & US10069936B2 — Data Communication System Patents
The three patents at issue — US10484510B2 (App. No. 16/278107), US10257319B2 (App. No. 15/957945), and US10069936B2 (App. No. 14/025109) — form a patent family covering systems designed to provide faster and more efficient data communication. The application filing sequence from App. No. 14/025109 through to 16/278107 is consistent with a continuation or continuation-in-part strategy, suggesting Bright Data sought to extend and refine its core proxy communication claims across multiple prosecution tracks.
For the internet data collection and proxy infrastructure sector, these patents represented meaningful IP assets — covering system-level improvements to how data requests are routed, processed, and returned across proxy networks. The Federal Circuit’s affirmance of unpatentability across all three family members weakens Bright Data’s ability to assert proprietary rights in this architecture. Competitors developing proxy-based data pipelines, residential proxy networks, or data communication acceleration platforms should note that the core claim structures did not survive appellate review.
Should you run an FTO against US10484510B2, US10257319B2, and US10069936B2?
Product teams building proxy infrastructure, residential proxy services, or data communication acceleration systems should be aware that all three Bright Data patents have been affirmed unpatentable at the Federal Circuit. While these patents no longer present an enforcement risk under their current grant numbers, related Bright Data continuations or divisional applications — if any exist — may carry overlapping claim scope. An FTO review of the full family remains prudent before commercialising competing proxy or data routing technology.
PatSnap Eureka’s FTO Search Agent can map the full Bright Data patent family, identify any surviving related applications, and flag claim language that may overlap with your product’s technical architecture. For data communication and proxy infrastructure teams, Eureka surfaces both granted patents and pending applications, letting your IP counsel assess residual risk from the broader family even after this affirmance.

What this case signals for the data communication and proxy IP landscape
Three Federal Circuit-invalidated patents narrow the enforcement options for data infrastructure IP holders. Here is what IP teams should take away.
Multi-patent invalidation at the Federal Circuit is a high-value signal
When the Federal Circuit affirms unpatentability across three related patents in a single appeal, it signals systematic weakness in the underlying claim architecture. Companies holding similar proxy, data routing, or communication-efficiency patents should audit claim scope before investing in enforcement or licensing programs.
Data communication system patents face appellate scrutiny — prepare accordingly
The Basis of Termination as ‘Unpatentable’ — upheld on appeal — suggests the claims may have faced § 101, § 102, or § 103 challenges that the Federal Circuit found persuasive. R&D teams drafting new applications in the proxy and data collection space should build prosecution records that clearly distinguish over prior art and address eligibility concerns early.
Bright v Data — key questions answered
The Federal Circuit affirmed the unpatentability of all three Bright Data patents — US10484510B2, US10257319B2, and US10069936B2 — on 1 August 2025. The court found no reversible error in the lower tribunal’s invalidity determination, making the unpatentability finding final at the appellate level.
Three patents were affirmed unpatentable: US10484510B2 (App. No. 16/278107), US10257319B2 (App. No. 15/957945), and US10069936B2 (App. No. 14/025109). All three cover systems providing faster and more efficient data communication, consistent with Bright Data’s proxy infrastructure technology.
An affirmance means the Federal Circuit found no reversible legal or factual error in the unpatentability ruling below. All three patents are now unenforceable. Bright Data’s remaining federal recourse would be a Supreme Court petition — statistically unlikely to be granted. The patents cannot be asserted in future litigation under their current grant numbers.
The appeal was filed on 13 July 2023 and closed on 1 August 2025 — a duration of approximately 750 days. This is consistent with multi-patent Federal Circuit appeals involving substantive patentability arguments, which typically require full briefing, possible oral argument, and panel deliberation.
The affirmance forecloses enforcement of the three specific patents. However, if Bright Data has pending continuation or divisional applications with overlapping claim scope, those could theoretically be pursued — subject to estoppel arguments arising from the invalidity proceedings. Companies monitoring Bright Data’s IP position should track its prosecution activity at the USPTO for related family members.
