Federal Circuit Affirms Invalidity of Bright Data’s Data Communication Patent Against Major Data UAB

Introduction

In a significant ruling for the data infrastructure and proxy technology sector, the U.S. Court of Appeals for the Federal Circuit affirmed the invalidity of Bright Data, Ltd.’s patent in *Bright Data, Ltd. v. Major Data UAB* (Case No. 23-2415), closing a 679-day appellate battle on August 1, 2025. The court upheld the lower tribunal’s finding that U.S. Patent No. US10484510B2—directed to a system providing faster and more efficient data communication—was unpatentable, delivering a decisive outcome on patentability grounds.

For patent attorneys tracking data communication patent litigation, this case offers meaningful precedent on invalidity and cancellation actions in the Federal Circuit. For IP professionals and R&D teams operating in the web data, proxy infrastructure, and network optimization space, the ruling signals important considerations around patent prosecution quality, claim drafting, and freedom-to-operate (FTO) analysis in a fast-evolving technology landscape.

Case Overview

The Parties

The Patent at Issue

At the center of this dispute is U.S. Patent No. US10484510B2 (Application No. US16/278107), which covers a system providing faster and more efficient data communication. This patent broadly relates to network communication architectures designed to optimize data transfer speed and efficiency—a foundational technology claim in the proxy and web data infrastructure market where Bright Data holds significant commercial interest.

• • US10484510B2 — System providing faster and more efficient data communication

The Accused Product

The litigation centered on data communication systems and infrastructure alleged to embody the claimed invention. Given the nature of the patent, commercial products or services offering enhanced data routing, proxy-based communication, or optimized network data delivery would fall within the scope of the assertion.

Legal Representation

– Plaintiff (Bright Data): Robert M. Harkins and Thomas M. Dunham of Cherian LLP

– Defendant (Major Data UAB): Wensheng Ma of Maschoff Brennan PLLC

Both firms bring established IP litigation credentials, with Maschoff Brennan recognized for its patent defense work across technology sectors.

Litigation Timeline & Procedural History

The matter was filed directly at the appellate level before the Court of Appeals for the Federal Circuit—the specialized Article III court with exclusive jurisdiction over patent appeals—on September 22, 2023. This indicates the appeal followed earlier proceedings, with the Federal Circuit reviewing a patentability determination that found US10484510B2 unpatentable.

The 679-day duration from filing to closure reflects the Federal Circuit’s standard appellate briefing and consideration timeline for patent validity matters, which typically involve complex technical records and extensive briefing cycles. The case was venued in the District of Columbia circuit jurisdiction, consistent with Federal Circuit practice. No chief judge assignment data was provided for this matter in the available case record.

The Verdict & Legal Analysis

Outcome

The Federal Circuit issued a clean AFFIRMED judgment, upholding the underlying invalidity/cancellation determination against U.S. Patent No. US10484510B2. The court found the patent unpatentable, ending Bright Data’s appellate challenge. No damages award is reflected in the case record, consistent with an invalidity proceeding rather than an infringement damages action. No injunctive relief information was disclosed in available case data.

Verdict Cause Analysis: Invalidity and Unpatentability

The verdict cause is designated as Patentability, with the specific action classified as an Invalidity/Cancellation Action—a proceeding challenging the fundamental legal validity of the patent itself rather than adjudicating infringement on the merits.

In Federal Circuit jurisprudence, invalidity findings on appeal are reviewed under exacting standards. When a patent is found unpatentable—as here—the analysis typically engages one or more of the following statutory grounds under 35 U.S.C.:

• • § 102 (Anticipation): Prior art fully disclosing the claimed invention
• • § 103 (Obviousness): Claimed invention obvious to a person of ordinary skill
• • § 101 (Patent-Eligible Subject Matter): Particularly relevant for data communication and software-implemented inventions

Given the patent’s subject matter—systems for faster and more efficient data communication—§ 101 eligibility challenges and obviousness arguments under § 103 are commonly dispositive in this technology category. Data communication optimization patents have faced sustained scrutiny under *Alice Corp. v. CLS Bank International*, 573 U.S. 208 (2014), where abstract ideas implemented through conventional computer components have been found patent-ineligible. While the specific legal basis for invalidity was not detailed in the available case record, practitioners should examine the full Federal Circuit opinion for the precise statutory grounds affirmed.

The affirmance by the Federal Circuit means the appellate court found no reversible error in the lower tribunal’s patentability analysis—a significant evidentiary and legal validation of the invalidity finding.

Legal Significance

1. Federal Circuit Imprimatur: An affirmance from the nation’s preeminent patent court gives the invalidity determination strong precedential weight in future proceedings involving similar data communication system claims.
2. Claim Scope in Data Infrastructure Patents: The outcome reinforces the vulnerability of broad data communication system patents when facing rigorous invalidity challenges, particularly where claimed “efficiency” improvements may lack sufficient differentiation from prior art.
3. Cancellation Proceedings: The invalidity/cancellation action framing suggests this may have originated through **inter partes review (IPR)** or similar USPTO post-grant proceedings before reaching the Federal Circuit—a pathway that has proven highly effective for patent challengers in the technology sector.

Strategic Takeaways

For Patent Holders:

• Prosecution strategy for data communication patents must anticipate § 101 and § 103 challenges with robust claim differentiation and detailed written descriptions supporting non-obviousness
• Appeal strategies following invalidity findings require a comprehensive record demonstrating claim construction errors or misapplied prior art standards

For Accused Infringers and Patent Challengers:

• IPR and post-grant invalidity proceedings remain powerful, cost-effective tools against data communication patents with broad functional claims
• Maschoff Brennan’s successful defense illustrates the value of specialized patent validity counsel in appellate proceedings

For R&D Teams:

• FTO analyses for data communication systems and proxy infrastructure products should account for the landscape of Bright Data’s patent portfolio, noting that US10484510B2 is now invalidated
• Design-around strategies for “efficient data communication” system architectures should be documented during development to support future invalidity arguments if needed

Industry & Competitive Implications

The invalidation of US10484510B2 has direct competitive implications for the web data collection, proxy network, and data infrastructure market—a sector experiencing rapid growth driven by AI training data demand, market intelligence, and automated web access services.

For Bright Data, losing appellate protection on this patent narrows one layer of its IP enforcement capability, though the company maintains a broad portfolio. Competitors and new market entrants in the data communication optimization space gain operational freedom previously constrained by this patent’s claims.

For Major Data UAB and similarly situated data service providers, the ruling affirms that Federal Circuit-level invalidity challenges can succeed even against established, well-resourced patent holders. This may encourage similar challenges to other patents in Bright Data’s portfolio or comparable patents across the proxy and network data sector.

More broadly, the case reflects a continuing industry trend in which data infrastructure patents face elevated invalidity risk when their claims are broadly drawn around functional efficiency improvements without sufficiently differentiated technical implementations. Companies investing in this space should anticipate that patent portfolios emphasizing architectural specificity and concrete technical solutions will demonstrate greater litigation durability than functionally framed claims.
