Amgen hit with $50.3 mln US verdict in cancer drug patent lawsuit

By Blake Brittain

Dec 18 - Amgen's AMGN.O leukemia drug Blincyto infringes patents owned by Germany's Lindis Biotech, a Delaware federal jury said in a verdict made public on Wednesday, awarding Lindis $50.3 million in damages.

The jury said that Amgen infringed two Lindis patents covering immunotherapy innovations. The verdict said Amgen's infringement was willful, which could lead the court to increase the damages award up to $150.9 million.

An Amgen spokesperson said the company was disappointed with the verdict and would seek to overturn it. Attorneys and spokespersons for Lindis did not immediately respond to a request for comment.

Amgen earned $566 million from U.S. sales of Blincyto in 2023, according to a company report.

Lindis sued the Thousand Oaks, California-based Amgen in 2022. It said that Blincyto mimicked Lindis' patented method of using "bispecific" antibodies to stimulate the body's immune system to kill cancer cells.

Amgen denied the allegations and argued that the patents were invalid.

The case is Lindis Biotech GmbH v. Amgen Inc, U.S. District Court for the District of Delaware, No. 1:22-cv-00035.

For Lindis: James Taylor, Jessica Jones, Henry Platt, Robert Gill, Matthew Antonelli, Alireza Behrooz, Dennis Ostrovsky and Courtland Merrill of Saul Ewing

For Amgen: Michael Wise, Joseph Hamilton, Lara Dueppen, Courtney Prochnow and Alisha Burgin of Perkins Coie; Lisa Pensabene, Hassen Sayeed, Carolyn Wall, Luann Simmons and Sorin Zaharia of O'Melveny & Myers
