Patexia Insight 86: Best Firms for ANDA Litigation in 2020

This morning we released our first ANDA Litigation Intelligence Report. For the first time, we ranked all attorneys and law firms by their activity and performance for Hatch-Waxman litigation. Our research team analyzed the outcome of 976 ANDA cases filed by pharmaceutical companies from June 1, 2017, through June 1, 2020.

For a total of 551 terminated cases, we identified the outcome (e.g., non-infringement, invalidity, settlement, etc.). Then, depending on the outcome and win/loss of parties (i.e., defendants and plaintiffs), we allocated points to each side, including the law firms and attorneys representing them to calculate their performance. The ANDA litigation is very important for both brand and generic pharmaceutical companies as the outcome sometimes can significantly impact their profitability.

This 114-page report, which covers all of the nearly 240 law firms, 1,105 attorneys including local counsel, 320 pharmaceutical companies (generic and brand), as well as 97 judges is available to Patexia Concierge members on the site and in PDF format. It can also be purchased online through Patexia, but here we will cover some of the highlights including a number of the top law firms, as identified and covered in our 2020 report.

                                          ANDA Reports



Out of a total of 976 ANDA cases filed during the period of our study, as of June 25, 2020, a total of 551 cases had been terminated, while the rest were in different phases and were still pending.

As we explained in the report (Section 1 - Ranking Methodology) and will summarize it here, we designed a method to measure the activity and performance of all stakeholders. As for the activity, it was simple: we counted all of the ANDA cases in which a company or its representatives (i.e., law firms or attorneys) were named in one of the public documents available through PACER (e.g., complaint or power of attorney). For the performance calculation, we used the following table to first calculate the success for each party, and then using a weighted average function, calculate the performance as a function of both activity and success.

The ANDA cases analyzed were represented by 10 official PACER outcome classifications:

  1. Judgment - Judgment on Consent
  2. Judgment - Motion Brief Trial
  3. Judgment - Court Trial
  4. Judgment - Other
  5. Dismissed - Settled
  6. Dismissed - Voluntarily
  7. Dismissed - Other
  8. Transfer/Remand - MDL Transfer
  9. Statistical Closing
  10. Non-reportable Closing

Six of these PACER classifications (numbers 5 through 10) are listed directly in table below. The four other outcomes in the table, reflect a case's practical outcome, as drawn from a case-by-case analysis of all cases within the remaining four (numbers 1 through 4), PACER "Judgment" categories. Of all categories of case closures in the following table, only four are scorable. Blank entries (dashes) in any columns/rows indicate the respective participant was not scored for that particular outcome.

We measured both activity and performance, for three separate categories:

  • Defendants
  • Plaintiffs
  • Overall

We ended up with a total of six categories. We ranked the Best Performing and Most Active law firms for the period of this study.

Since more than 90 percent of all cases had been filed in either Delaware or New Jersey District Courts, local counsel and their impact on the outcome of the cases became clear (e.g., their past experience with ANDA cases, familiarity with the venue, judges, etc.). So we also decided to dedicate a separate section to local counsel and rank the most active counsel.

Here are some of the highlights from the report (in alphabetical order):

  • Alston & Bird with a total of 3 ANDA cases (all on the generic side), ranked the 29th Best Performing Firm for representing defendants. The firm was also among the Top 50 Most Active ones.
  • Carlson Caspers with 12 cases and representing defendants in all of them, was one of the Top 10 Best Performing Firms for representing generic pharmaceuticals (defendants). In terms of activity, the firm was ranked the 18th Most Active firm for representing generic pharmaceuticals. The firm was ranked as one of the Top 25 Best Performing firms overall.
  • Husch Blackwell with a total of 9 cases was ranked in the Top 50 in multiple categories, including 26th Most Active Firm for representing generic pharmaceuticals. The firm is mainly active on the generic side although they have also been active on the brand side and ranked the 50th Most Active firm for representing brand pharmaceuticals. In terms of performance, the firm is among the top 50 for both brand and generic pharmaceuticals.
  • Knobbe Martens with a total fo 12 cases, only represented generic pharmaceuticals (defendants). In terms of activity, Knobbe is the 13th Most Active firm for representing defendants. In terms of performance, we were not able to rank the firm yet as none of the 12 cases for the period of the study had reached a conclusion.

In all cases, the firm represented the generic pharmaceuticals and was ranked the 13th Most Active Firm for representing defendants in ANDA cases.
