In January, we published the Patent Litigation 2023 Report analyzing all patent infringement cases filed in district courts during the period from July 1, 2017, to June 30, 2022. In this report, we also cover some of the most important lateral moves of patent litigators that happened last year.

In recent months, we've shared several insights from our 2023 report, ranging from an encompassing view of some of the best-performing and most active patent litigators in the US (Patexia 179 and Patexia 167) to the companies that stood out among the best-performing and most active plaintiffs and defendants (Patexia 171 and Patexia 168). As per tradition, the report also included the section dedicated to the lateral moves among the top 1,000 most active attorneys, as they transitioned between law firms in 2022 which will be the focus of this week’s insight.

A total of 17,052 patent litigators represented either plaintiffs or defendants in district court patent litigation cases during the five-year period of our study. By comparing the information we obtained from attorneys and law firms with those published in our previous report, we identified the ones who made lateral moves. We uncovered a total of 53 lateral movements among the top 1,000 attorneys as ranked by activity in the Patent Litigation 2023 Report. The following table shows the top 25 lateral moves, as sorted by the activity rank of the attorneys:

We have observed that often, a single plaintiff with a limited number of patents may sue hundreds of companies in multiple cases. While more defendants mean more work for them, the amount of work does not increase proportionally with the number of cases filed using the same patents. Therefore, the calculation of the activity score and rank assigned to each attorney entails a comprehensive approach, incorporating a weighted function that takes into account not only the number of cases managed but also the patents involved.

Law firms continually strategize to capitalize on shifts within the patent litigation landscape. Drawing insights from the data acquired through lateral moves, we compiled a list of law firms that have experienced notable fluctuations in their litigator headcounts. This analysis involved subtracting the number of attorneys who joined a firm from those who departed, enabling us to identify those firms that demonstrated substantial growth or decline in their number of litigators. This approach provides a dynamic perspective on the evolving legal landscape, shedding light on the tactical decisions and trends that have influenced the composition of litigators within various law firms.

Among the law firms that have experienced significant attorney growth in 2022, we find notable names like Morrison & Foerster, BC Law Group, P.C., Kirkland & Ellis, McKool Smith, and Skiermont Derby. Morrison & Foerster takes the lead with a net gain of 7 litigators due to its acquisition of Durie Tangri. The other firms in this group maintain an average gain of 2.5 attorneys per firm.

Morrison & Foerster appears regularly among Patexia’s various law firm rankings. With over 1,000 attorneys, the firm has recently represented Apple, Genentech, Inc., and Xilinx, among others. In recent years, the firm has expanded considerably, especially after the acquisition of Durie Tangri bringing in 36 new attorneys. Among the new patent litigators in the firm are, Brian C. Nash, Daralyn J. Durie, Adam R. Brausa, Eric C. Wiener, Austin M. Schnell, and Timothy C. Saulsbury – all ranked highly on Patent Litigation Report’s 2023 top 1,000 most active attorneys.
BC Law Group, P.C. was founded by IP attorneys from McKool Smith, who started this boutique law firm and have taken on cases for Scramoge Technology Ltd., Sonrai Memoty Limited, and Lionra Technologies Limited.
