A Chinese professor charged in connection with an intellectual property dispute involving the Chinese telecom company Huawei was brought from the Dallas area to Brooklyn for reasons that cannot be publicly disclosed, prosecutors revealed in court Wednesday afternoon.

Bo Mao, 36, is accused of helping steal proprietary technology from a California startup to help Huawei, according to documents filed in Texas and New York federal courts. He has pleaded not guilty to one count of conspiracy to commit wire fraud.

The motion to move the case to the Eastern District of New York contained grand jury information that cannot be released to the public or to Mao's defense attorneys, despite their requests to see it, Assistant U.S. Attorney Alexander Solomon said in court.

One of Mao's defense attorneys, Thompson & Knight partner Richard Roper of Fort Worth, Texas, said he doesn't understand why the case has any connection to the Eastern District of New York at all.

"If there's some outrageous … information relating to my client, I'd certainly like to see it," Roper said.

U.S. District Judge Ann Donnelly of the Eastern District of New York told Roper she didn't have much more to share about the venue.

Donnelly is also the judge in at least one more matter concerning Huawei, which wasn't discussed in court Wednesday.

In that case, prosecutors charged Huawei, one Huawei subsidiary and the company's chief financial officer with bank fraud, wire fraud and conspiracy to commit bank and wire fraud in January. Huawei and another subsidiary were also charged with conspiracy to obstruct justice related to a grand jury investigation in the Eastern District of New York.

The government has redacted and sealed various documents in that case. In court Wednesday, Solomon said the Mao case will also involve classified materials, although he said he didn't expect Mao's defense lawyers to need security clearances.

Mao is scheduled to appear again in Donnelly's courtroom in November.
