Jury selection is scheduled to begin on Tuesday.
The indictment alleges that, besides stealing trade secrets, Huawei and some of its subsidiaries did business in North Korea despite US sanctions there and installed surveillance equipment that helped Iran spy on protesters during 2009 anti-government demonstrations in Iran.
Huawei's lawyers have tried to get the broad criminal case dismissed, arguing in court filings that the US allegations were too vague, that some were "impermissibly extraterritorial," and did not involve domestic wire and bank fraud.
Huawei is the world's biggest supplier of gear for wireless telecom networks but the company is banned from selling equipment to US carriers over fears it poses a security risk. It has also been blacklisted by other Western allies like Canada and Britain.
The company makes phones and other consumer electronics but has been cut off from other lines of business. More recently it has expanded into chipmaking as the boom in artificial intelligence fuels demand for microprocessors.
During President Donald Trump's first term in office, his administration raised national security concerns about Huawei and began lobbying Western allies against including the company's products in their next-generation high-speed wireless networks. The US announced the criminal charges in early 2019 and has since expanded the allegations.
Chinese officials said the US government has engaged in "economic bullying" and improperly used national security as a pretext for "oppressing Chinese companies."
US prosecutors accused Huawei of using a Hong Kong shell company known as Skycom to sell equipment to Iran in violation of US sanctions. They also charged its chief financial officer, Meng Wanzhou, with fraud, saying she misled HSBC bank about the company's business dealings in Iran.
Meng, the daughter of Huawei's founder, was arrested in Canada in late 2018 on a US extradition request but released in September 2021 in a high-stakes prisoner swap that freed two Canadians held by China and allowed her to return home.
As part of the deal, the US dropped its extradition request and said it would dismiss the fraud charges against Meng.
The biggest maker of network gear, Huawei struggled to hold onto its market share under sanctions that have blocked its access to most US processor chips and other technology. The limits led it to ramp up its own development of computer chips and other advanced technologies.
