Item 8.01 Other Events.

Enzo Biochem, Inc. (NYSE: ENZ) today announced that the United States Court of Appeals for the Federal Circuit (“Federal Circuit”) issued an opinion dated June 20, 2019, affirming the lower court judgments of patent invalidity for U.S. Patent Nos. 6,992,180 and 8,097,405 that were made by the United States District Court for the District of Delaware in Enzo v. Roche, Case No. 1:12-cv-00106-LPS, Enzo v. Abbott Laboratories, Case No. 1:13-cv-00225-LPS, Enzo v. Abbott Laboratories, Case No. 1:12-cv-00274-LPS, and Enzo v. Becton Dickinson, Case No. 1:12-cv-00275-LPS. The Company is considering all available options for challenging the Federal Circuit panel’s decision. The Federal Circuit panel’s decision does not concern Enzo’s U.S. Patent No. 7,064,197, claims of which have been asserted against Roche in Case No. 1:12-cv-00106-LPS and against Becton Dickinson in Case No. 1:12-cv-00275-LPS.
