This patent infringement litigation, Case No. 1:17-cv-12499, was filed in the U.S. District Court for the District of Massachusetts, presided over by Judge Indira Talwani. The plaintiff is Realtime Data LLC, operating as IXO, a prolific Non-Practicing Entity (NPE) known for asserting a broad portfolio of data compression patents against numerous companies across various industries. The defendant in this specific action was Carbonite, Inc., a company specializing in cloud backup and data recovery solutions. The accused products or services are Carbonite's offerings, specifically mentioned as including "Carbonite's Server Backup VM Edition," which allegedly infringed Realtime Data's patents related to data compression. This case was initially transferred to the District of Massachusetts from the Eastern District of Texas via a joint stipulation, a notable move given the frequent filings by NPEs in the latter venue.

The primary patent at issue, among others, is U.S. Patent No. 8,717,204 B2, titled "Systems and methods for accelerating data transmission." This patent generally describes technologies for enhancing the speed of data transmission over communication channels through data compression and decompression techniques. These methods involve analyzing data blocks, selecting appropriate compression algorithms based on data characteristics, and transmitting the compressed data to effectively increase bandwidth and reduce latency. Realtime Data has a history of asserting a family of patents related to data compression and data feed acceleration across many lawsuits.

The procedural posture of this case indicates significant activity. Following the transfer, a claim construction order was issued by Judge Talwani in December 2021, consolidating this case with other related Realtime Data actions against Acronis, Inc. and Sungard Availability Services, LP, all involving patents related to digital data treatment. Ultimately, in November 2022, Judge Talwani entered judgment in favor of Carbonite. This case is particularly notable due to Realtime Data's extensive patent assertion campaigns; since 2010, the company has accused over ninety different entities of infringement. Many of these cases, including those involving Realtime Data's asserted patents, have faced significant challenges under 35 U.S.C. § 101 concerning patent eligibility, leading to numerous invalidity findings at the district court level and subsequent appeals to the Federal Circuit. The involvement of an IPR proceeding (IPR2017-01826) also highlights the multi-front litigation strategy often seen in NPE assertions.

Realtime Data LLC v. Carbonite, Inc.: Key Legal Developments and Outcome

This patent infringement litigation, Realtime Data LLC d/b/a IXO v. Carbonite, Inc. (D. Mass. Case No. 1:17-cv-12499), involved allegations of infringement related to data compression patents, including U.S. Patent No. 8,717,204B2. The case saw significant legal developments, primarily revolving around challenges to patent eligibility under 35 U.S.C. § 101, ultimately culminating in a judgment of invalidity.

Filing & Initial Pleadings

The lawsuit was initially filed by Realtime Data LLC against Carbonite, Inc. on February 27, 2017, in the U.S. District Court for the Eastern District of Texas (Case No. 6:17-cv-00121-RWS-JDL), alleging infringement of certain data compression patents. The complaint sought unspecified damages and injunctive relief.

On December 19, 2017, the case was transferred from the Eastern District of Texas to the U.S. District Court for the District of Massachusetts, where it was assigned case number 1:17-cv-12499.

Pre-trial Motions of Substance

• Motion to Dismiss for Improper Venue: Prior to the transfer, Carbonite filed a motion to dismiss for improper venue, which was denied on August 21, 2017, in the Eastern District of Texas.
• Motion to Stay Pending IPR: Carbonite also filed a motion to stay the litigation pending the outcome of an Inter Partes Review (IPR). This motion was initially denied, but the court indicated that it could be renewed if the IPR was instituted. A decision on the institution of IPR2017-01826 was expected in February 2018.
• Patent Eligibility (Alice) Ruling (Eastern District of Texas): A report and recommendation from Magistrate Judge John D. Love of the Eastern District of Texas, dated September 20, 2017, in the original 6:17-cv-00121 case (which was later adopted by the Massachusetts court), found certain asserted patents (including '728, '530, and '908 patents, and members of the '203 and '751 patents' families, all related to data compression) to be patent eligible under both steps of the Alice test. This recommendation was adopted by Judge William G. Young in the District of Massachusetts on March 7, 2018.
• Stay Pending Related Delaware Litigation: On August 19, 2019, the U.S. District Court for the District of Massachusetts stayed the action against Carbonite. This stay was pending an appeal in a related lawsuit filed by Realtime Data against other companies in the U.S. District Court for the District of Delaware (e.g., D. Del. No. 1:17-cv-00800), where the Delaware court had dismissed the lawsuit on July 29, 2019, declaring three of the four patents asserted against Carbonite invalid under 35 U.S.C. § 101.
• Federal Circuit Vacates and Remands Delaware Decision: On October 23, 2020, the Federal Circuit vacated and remanded the Delaware court's decision, finding the initial § 101 analysis by the district court "too cursory to allow for meaningful appellate review." Following this, the Massachusetts District Court lifted its stay on the action against Carbonite.

Claim Construction (Markman)

Following the lifting of the stay, a claim construction hearing was held on January 21, 2021. On December 21, 2021, Judge Indira Talwani issued a single claim construction order in consolidated cases, including 1:17-cv-12499. This order construed five terms across four patents, which generally related to digital data, including the term "data stream."

Parallel PTAB IPR Proceedings

The U.S. Patent & Trademark Office Patent Trial and Appeal Board (PTAB) played a role in the litigation. On September 24, 2019, the PTAB invalidated certain claims of a "fourth patent" that had been asserted against Carbonite. Following this decision, the parties jointly stipulated to dismiss this particular patent from the district court action. The identity of this "fourth patent" is not explicitly stated as 8717204B2 in the provided information, but it was one of the patents asserted against Carbonite. While IPR2017-01826 was mentioned with an expected institution decision in February 2018, the specific outcome for patent 8717204B2 in that IPR is not directly detailed in the provided sources.

Outcome: Summary Judgment and Appeals

The litigation ultimately concluded with a judgment of invalidity based on patent-ineligibility under 35 U.S.C. § 101.

• Delaware District Court Reaffirms Invalidity: After the Federal Circuit's remand, the District of Delaware (in cases like Realtime Data LLC v. Array Networks Inc., 537 F. Supp. 3d 591 (D. Del. 2021) ("Realtime II") and 556 F. Supp. 3d 424 (D. Del. 2021) ("Realtime III")) once again found all asserted patents invalid under § 101, concluding they were directed to abstract ideas. The seven patents at issue in these Delaware appeals included U.S. Patent No. 8,717,203 ('203 patent), among others related to digital data compression. While U.S. Patent No. 8,717,204B2 is not explicitly listed as one of the seven, the '203 patent is a very similar patent in the same family, indicating a strong likelihood that the reasoning applied broadly to Realtime Data's data compression patents.
• Massachusetts District Court Grants Summary Judgment: Based on the August 23, 2021, order from the District of Delaware holding "all of the patents asserted against Carbonite to be invalid," the U.S. District Court for the District of Massachusetts, under Judge Talwani, granted summary judgment in Carbonite's favor in case 1:17-cv-12499. While the exact date of this summary judgment in the Massachusetts case is not explicitly stated, it occurred after August 23, 2021, and before November 10, 2022.
• Federal Circuit Affirms Invalidity: Realtime Data appealed the Massachusetts summary judgment. However, Realtime Data stipulated to stay its appeal pending the outcome of its appeal in the Delaware cases. On August 2, 2023, the U.S. Court of Appeals for the Federal Circuit affirmed the invalidity of the patents asserted against Carbonite in the related Delaware case (Case Nos. 2021-2251, 2021-2291), finding the claims directed to abstract ideas without an inventive concept. This affirmation by the Federal Circuit resolved the ongoing patent eligibility dispute against Realtime Data's patents. As per their stipulation, if the Federal Circuit affirmed the Delaware judgment of invalidity, Realtime Data would subsequently dismiss their appeal against Carbonite.
• Supreme Court Denies Certiorari: Realtime Data LLC sought a petition for certiorari to the U.S. Supreme Court to address the Federal Circuit's August 2023 decision, but the Supreme Court denied this petition on January 8, 2024, effectively ending the eligibility challenge.

The ultimate outcome for case 1:17-cv-12499 is that the asserted patents, including likely 8,717,204B2 based on the pattern of invalidity rulings against Realtime Data's data compression patents, were found invalid under 35 U.S.C. § 101.

I was unable to definitively identify the counsel of record representing defendant Carbonite, Inc. in case 1:17-cv-12499 in the Massachusetts District Court based on the provided web search results.

While the search results confirm that Carbonite, Inc. is the defendant in this patent infringement case brought by Realtime Data LLC, and detail various aspects of the case's procedural history including its transfer to the District of Massachusetts and subsequent rulings, they do not explicitly list the names of the attorneys or law firms that represented Carbonite, Inc. in this specific matter.

Information regarding attorneys for Realtime Data LLC was found in a Federal Circuit document (Case: 21-2251), but this pertains to the plaintiff-appellant, not the defendant. An older press release from 2013 mentioning Foley & Lardner LLP and attorney Andy Tindel as Carbonite's counsel was for a different patent suit and not directly applicable to the current case.
