The Week in Tech: Sundar Pichai Has a Chat With Congress

■ An argument often made against antitrust action is that the technology industry is dynamic, and that today’s dominant predator can become tomorrow’s prey. Nokia once dominated mobile phones but lost its standing to Samsung and Apple in the smartphone era.

Similarly, Intel, once so overwhelming a force in the semiconductor industry that it was a frequent target of antitrust cases, is struggling to keep pace with a shifting industry. My colleague Cade Metz explained how Amazon is the latest tech company to start building its own chips, threatening Intel’s grip on the server chip market.

■ It’s rare for a bail hearing to make international news, but this was no ordinary arrest.

Meng Wanzhou, chief financial officer of the tech behemoth Huawei and a daughter of the company’s founder, was arrested Dec. 1 at the airport in Vancouver, British Columbia, for extradition to the United States.

The American and Canadian authorities claim Ms. Meng circumvented trade sanctions against Iran, using a Huawei subsidiary. The arrest of a prominent executive at one of China’s biggest tech companies, with close ties to the government, complicates the Trump administration’s negotiations to end a trade war with China.

On Tuesday, a judge granted bail of 10 million Canadian dollars, or about $7.5 million. Ms. Meng agreed to 24-hour physical and electronic surveillance and a curfew.

■ China was at the center of another interesting tech industry news story. Qualcomm said a Chinese court had ordered Apple to stop selling older iPhones in China. The court, according to Qualcomm, said Apple had infringed on two Qualcomm patents and issued a preliminary injunction on seven older iPhone models.

It’s another sign of the deteriorating relationship between the two companies. Apple sued Qualcomm last year, accusing it of monopolistic practices. Qualcomm has accused Apple of patent infringement, while carrying out a public-relations campaign against the iPhone maker.
