Theranos creator Elizabeth Holmes appeared in a federal courtroom in San Jose, Calif., Tuesday for the first time in over a year, attending the very first in 3 days of discussions which will form what jurors could hear at her upcoming criminal fraud trial.

Prosecutors allege that she and former Chief Operating Officer Ramesh”Sunny” Balwani tricked patients and investors by asserting that the organization’s blood-testing technology can do more than it might.

The U.S. lawyer’s office in the Northern District of California and lawyers for Ms. Holmes have been sparring for weeks over the reach of proof to be allowed throughout the trial, that is now slated for late August. The trial was postponed several times, initially due to the coronavirus outbreak and many lately after Ms. Holmes told the court she’s expected to have a baby in July.

Ms. Holmes and Mr. Balwani, whose trial is going to be held individually following hers endings, have each pleaded not guilty.
