While changes such as the introduction of PTAB in 2012 or Alice 101 decision had impacted the patent litigation activity, in the first half of 2021 we saw a great recovery in patent litigation with more than 2000 cases over that six month period alone. With 14,506 patent cases filed over the last four years, patent litigation is increasing again.

Similar to other Patexia Insight Reports, this new report will cover all the stakeholders involved in district court patent litigation. The period of study covers all cases filed from July. 1, 2017, through Jun. 30, 2021. This period covers: 

  • 14,506 District Court Patent Cases
  • 12,293 Unique Patents
  • 14,251 Defendants and Plaintiffs
  • 3,050 Law Firms 
  • 14,685 Attorneys

Just like we did the last year again this year, even based on your feedback, we have decided to provide separate rankings for:

  • Patent Litigators (Partners, and Associates)
  • Local Counsel

Similar to other reports, the rankings will cover the "Most Active" and "Best Performing" in the following categories:

  • Defendants
  • Plaintiffs
  • Overall

The "Best Performing" category is calculated based on the outcome of all the terminated cases for the period of the study. Our research team will review the judgments and allocate points to respective parties.

We will provide an Excel file together with the report to cover up to the top 1,000 most active attorneys, law firms, companies, judges and top 3 clients for each firm and the top 3 law firms representing each company.
