Similar to prior years, the 2021 Edition is the all-inclusive report with rankings of law firms, attorneys, companies and PTAB judges under different categories (Petitioner, Patent Owner, and Overall)

This year, for the first time, we have also dedicated a section to lateral moves for IPR attorneys

The report covers 7,582 IPR cases for the last five years (from July 1, 2016 through June 30, 2021). 

We have analyzed more than 5,000 unique patents and around 80,000 unique claims challenged over the last five years, to come up with the Activity, Success, and Performance Scores for all attorneys, law firms and companies on the patent owner and petitioner sides. This includes a review of:

  • 7,582 IPR cases
  • 5,087 patents
  • 80,831 patent claims
  • 930 law firms
  • 5,341 attorneys
  • 2,658 companies
  • 195 judges

We have also made some adjustments to our models based on the survey we conducted and the feedback we received from the IP community. This includes an update to our ranking formula. 

In addition, due to requests we received from our clients, we have expanded the Excel file to cover up to 1000 most active law firms, attorneys, and companies with all their stats and scores for the last five years.

Similar to last year, we will provide a Press Kit and the firms will be able to have a press release or publish the digital badges on their sites.
