Samsung Electronics failed to convince an East Texas federal court on Friday to pause the California Institute of Technology’s high-stakes patent lawsuit against it while it challenges the patents’ validity at the U.S. Patent and Trademark Office.

U.S. District Judge Rodney Gilstrap said halting the lawsuit until the Patent Trial and Appeal Board reviews the patents would unnecessarily delay the court case and prejudice Caltech.

Caltech had no comment on the decision. Representatives for Samsung and Caltech did not immediately respond to a request for comment.

Caltech sued Samsung after it won a $1.1 billion California jury verdict in 2020 against Apple and Broadcom in a dispute over some of the same patents. A U.S. appeals court tossed the verdict last year and remanded for a new trial on damages.

The school’s 2021 lawsuit alleges Samsung’s Galaxy phones, tablets, watches and Wi-Fi-enabled Samsung products like televisions and refrigerators infringe its data-transmission patents.
