The Latest Information Regarding All Legal Proceedings Between Oxylabs and Luminati (now Bright Data)

Our commitment to a fair market in which innovation thrives through legitimate competition

The story’s first chapter dates back to July 2018, when Luminati (now Bright Data) sued Oxylabs, claiming that Oxylabs’ technology infringed Bright Data’s patents. Oxylabs has always maintained the position that Oxylabs has not infringed on any of Bright Data’s patents.

In fact, Bright Data’s allegations were resolved in the first concluded case, as a settlement was reached between both parties, resulting in all claims and counterclaims in the case being dismissed with prejudice. Hence, our existing and future partners should not be concerned regarding Bright Data’s messages regarding Oxylabs' products.

That said, little did we know at the time, for Bright Data, it wasn’t necessarily all about winning the case. As further actions against us have shown, it seems Bright Data’s aim might be all about tying up its competition in endless legal proceedings, distracting its rivals from their core business operations, and discouraging regular companies from using non-Bright Data proxy providers. Indeed, Bright Data filed two additional lawsuits against Oxylabs. In those lawsuits, Oxylabs asserts that Bright Data’s patents are not infringed, are invalid, and are not eligible for patent protection.

Hence, Oxylabs will continue to protect its technology and reputation utilizing all available legal remedies, including appellate process to ensure fair market practices that encourage legitimate competition for all market stakeholders’ interests.

Case No. 299

Luminati (now Bright Data) filed a complaint against Oxylabs

Luminati (now Bright Data) sued Oxylabs, claiming that two Oxylabs’ products - Oxylabs’ residential proxy network service and Real-Time Crawler - allegedly infringed Bright Data’s two patents, U.S. Patents 9,241,044 and 9,742,866

(Case No. 299)


August 21, 2019

Case No. 299

Claim Construction Order

The Court issued its claim construction[1] opinion (a so-called Markman[2] opinion), which proved to be critical for the later stages of Case No. 299. With this decision, at Oxylabs’ request, the Court invalidated one of the three independent claims of Bright Data’s patents (Claim 108) as indefinite and issued an order construing the claims of Bright Data’s patents.

September 09, 2019

Case No. 299

Oxylabs filed Alice Motion

Oxylabs filed its Motion for Judgment on the Pleadings[3] (a so-called Alice Motion[4]) seeking a ruling that Bright Data’s patents were invalid for impermissibly claiming an abstract idea.

November 04, 2019

Case No. 299

Oxylabs filed Motion for Summary Judgment

Oxylabs also filed a Motion for Summary Judgment that Oxylabs did not infringe Bright Data’s patents. Both motions (i.e., Motion for Judgment on the Pleadings and Motion for Summary Judgment) were pending, and if the Court had granted either of them, the lawsuit would have concluded on the merits in Oxylabs’ favor.

November 05, 2019

Case No. 299

Luminati (now Bright Data) withdrew non-patent claims

On December 12, 2018, in Case No. 299, Bright Data asserted certain non-patent claims against Oxylabs. Oxylabs wrote to Bright Data on September 10, 2019, and advised that these additional claims asserted in Case No. 299 were frivolous and that the continued pursuit of the claims would subject Bright Data to liability for Oxylabs’ attorney’s fees. On November 4, 2019, rather than pursue these additional non-patent claims asserted in Case No. 299Bright Data voluntarily withdrew them without prejudice.

December 06, 2019

Case No. 395

Case No. 396

Luminati (now Bright Data) filed two new complaints against Oxylabs

In Case No. 395, Bright Data also once again asserted the same additional non-patent claims, which Bright Data voluntarily withdrew in Case No. 299 back in November 2019.


January 03, 2020

Case No. 299

Case resolved by settlement

Case No. 299

Case dismissed with prejudice in accordance with the parties’ settlement agreement

The claims asserted by Oxylabs include: violation and conspiracy to violate the antitrust laws of the United States, monopolization and attempted monopolization of the residential proxy marketplace, and the filing of sham patent-infringement lawsuits against competitors, including Oxylabs. To promote fair marketplace practices, Oxylabs sought to redress the injuries it has suffered and hold Bright Data, EMK Capital, and Hola accountable for their actions.

Subject to the Stipulation, Bright Data moved to dismiss its claims of infringement against Metacluster with prejudice, and defendants agreed to the dismissal. Based on the parties’ Stipulation, the Court entered an Order on July 2, 2021, dismissing Bright Data’s claims against Metacluster with prejudice.

November 05, 2021

Case No. 395

Certain claims infringed and not invalid

The jury issued a verdict finding certain claims infringed and not invalid. While we are disappointed in the decision, we thank the jury for their service. We note that the jury’s decision relates solely to a claim for monetary damages. Oxylabs is legally entitled to continue providing the accused services. The Court has not issued any orders related to continued use of Oxylabs’ residential proxy service. We intend to continue to pursue our positions both with the District Court and, if necessary, at the Court of Appeals. Oxylabs continues to offer its services in an uninterrupted manner.

Legal terminology

1. Claim Construction Order is the process of giving meaning to a patent’s claims by defining selected claim terms.

2. Markman Hearing is a pretrial hearing in a U.S. District Court during which a judge examines evidence from all parties on the appropriate meanings of relevant keywords used in a patent claim. “Markman” comes from the United States Supreme Court’s decision in Markman v. Westview Instruments, Inc., 517 U.S. 370 (1996), which held that it is up to the Court (as opposed to a jury) to interpret a patent’s claims. A Markman hearing is also known as a “claim construction hearing.”

3. Motion for Judgment on the Pleadings/Motion to Dismiss are motions that a party to a lawsuit may file, asking the Court to dismiss the case before it proceeds to discovery and a trial. They are motions taking issue with a party’s claim as a matter of law.

4. Alice Motion refers to the United States Supreme Court’s decision in Alice Corp. Pty. Ltd. v. CLS Bank Int’l, 573 U.S. 208 (2014), which held that a trial court must determine whether a patent is invalid for claiming unpatentable subject matter. The trial court must first determine whether the challenged claims “are directed to a patent-ineligible concept,” i.e., an abstract idea. If the claims are directed to an abstract idea, the Court then must determine whether the claims recite “additional elements” that “transform the nature” of the claims into a patent-eligible application of the abstract idea.

5. Pretrial conference is a Court hearing with the Judge and the parties to a case conducted prior to trial.

6. Inter Partes Review (IPR) - Inter partes review is a trial proceeding conducted at the Patent Trial and Appeals Board to review the patentability of one or more claims in a patent only on a ground that could be raised under §§ 102 or 103, and only on the basis of prior art consisting of patents or printed publications.

7. Ex Partes Reexamination (EPR) - Ex parte reexamination may be requested by either a patent owner or a third party in order to challenge the novelty or nonobviousness of one or more claims in a patent. The scope of prior art submitted in support of the challenge is limited to printed publications and patents, while other types of prior art (such as product prior art) cannot be raised in a request for ex parte reexamination.

8. Post Grant Review (PGR) – With respect to newer issued patents, Post Grant Review process begins with a third party filing a petition on or prior to 9 months after the grant of the patent or issuance of a reissue patent. A post grant review may be instituted upon a showing that it is more likely than not that at least one claim challenged is unpatentable.
