Seagen’s patent lawsuit against Daiichi Sankyo is nearing resolution at the district court. In April of this year, Seagen convinced a Texas jury that Daiichi Sankyo’s breast cancer drug, Enhertu®, is infrining Seagen’s U.S. Patent No. 10,808,039. Daiichi Sankyo also failed to convince the jury that the ‘039 patent was invalid. As a result, the federal court in the Eastern District of Texas is scheduled to conduct a bench trial on what appears to be Daiichi Sankyo’s last defense before the Court enters judgment. On June 28, the court will conduct a bench trial (no jury) on the issue of prosecution laches. The trial is scheduled to commence at 1:00 pm and will last only three hours. Can Daiichi Sankyo avoid paying Seagen royalties?
