He has added to that list since taking office. Over the last three weeks, China’s trademark office gave preliminary approval for one trademark to Mr. Trump for providing catering services and four to his daughter through her trademarking business, Ivanka Trump Marks. Ms. Trump’s trademarks include those for jewelry, wedding dresses, watches and a range of electronic devices.

Mr. Trump applied for the trademark in April 2016, while his daughter applied for the four trademarks from May to July last year.

Mr. Trump has at least 89 trademarks registered and 28 others that have won preliminary approval. His daughter now has 17 registered trademarks and six that have won preliminary approval. Trademarks with preliminary approval are formally registered three months later if officials receive no objections.

Abigail Klem, the president of Ivanka Trump’s company, said that those trademarks were made “in the normal course of business” and noted that the company had taken similar steps in the past, “especially in regions where trademark infringement is rampant.”

She said the firm had seen a “surge” in companies trying to capitalize on the Trump name. “It is our responsibility to diligently protect our trademark,” she said.
