Lex Machina Releases 2024 Patent Litigation Report

February 08, 2024

Patent case filings continued the decreasing trend exhibited since 2021, likely driven by the drop in cases filed by high-volume plaintiffs over the same period of time, and case filings before Judge Albright and the Western District of Texas declined in 2023


Menlo Park, CA — Lex Machina, a LexisNexis company, today releases its annual Patent Litigation Report. The report examines trends in patent litigation in federal district courts, appellate courts, and the Patent Trial and Appeal Board (PTAB). Focusing on the three-year period from 2021 to 2023, it surveys emerging trends in case filings, venues, judges, law firms, parties, timing metrics, case resolutions, findings, and damages. The report often focuses on different sets of data, e.g., filtering cases in order to provide analytics on general patent, high-volume plaintiff, ANDA, PTAB, and federal appellate cases.

“Our data illuminates several intriguing recent trends in patent litigation,” said Elaine Chow, Lex Machina’s patent legal data expert and editor of the report. “In this report, we see a continuation of the recent decrease in general patent case filings, which is likely caused, at least in part, by the drop in cases filed by high-volume plaintiffs. We also see that the Western District of Texas in general, and Judge Albright in particular, both fell from the top of the case filing tables in 2023. These data-backed trends can be linked to external circumstances in the legal profession, such as judicial orders.”

Findings from the report include:

  • Highlights in federal district and appellate courts:
    • In 2023, 3,111 patent cases were filed, continuing the steady decline of patent case filings since 2021.
    • The Western District of Texas was the most active district from 2021 to 2023 with 22% of all patent cases filed, though the number of patent cases filed in 2023 in this court dropped significantly compared to the previous two years.
    • Judge Albright was assigned to the highest number of patent cases from 2021 to 2023 with 1,844 cases, though his assigned patent cases in 2023 dropped significantly compared to the previous two years.
    • Ramey represented plaintiffs in the highest number of patent cases filed from 2021 to 2023, and Fish & Richardson represented defendants in the highest number of cases filed in the same three-year period.
    • For patent cases that were appealed to a federal appellate court and terminated from 2021 to 2023 with a decision on the merits of the appeal, 34% were ultimately reversed.
    • From 2021 to 2023, $6 billion in total damages were awarded as Reasonable Royalty across 129 cases.
  • Highlights in PTAB:
    • The number of PTAB petitions filed dropped in 2023.
    • There was a slight increase in instituted trials compared with the data reported in the 2023 Patent Litigation Report (from 51% to 54%).
    • For PTAB cases that were appealed to a federal appellate court and terminated from 2021 to 2023 with a decision on the merits of the appeal, 22% were ultimately reversed.
    • Samsung was the most active petitioner in PTAB petitions filed during the three-year period from 2021 to 2023.
    • Fish & Richardson represented parties in the highest number of petitions filed from 2021 to 2023.
