A Beijing regulator said it would bar Apple from selling its iPhone 6 and 6 Plus models because of "patent infringement" against 100C mobile phones.
But what is 100C (also branded as 100+)? CNBC was unable to find an official website for the brand — either in Chinese or English, but reports indicate it is a model owned by Shenzhen Baili Marketing Services.
Some online photos of 100C phones showed a web address on their backside "100jia.cn," but that appeared not to currently exist.
A phone number listed online for Shenzhen Baili proved to be for a disconnected line, and an inquiry to an email address failed to successfully deliver.
Scant information was available about the company, but research from China International Capital Corp. appeared to show the company had 29.6 million yuan ($4.5 million) in 2013 operating income.
Beijing Business Today struggled to find many details about Baili, writing that the company did not seem to be a patent troll, but that it went a long time without introducing new products and did not appear to have an official website.
Apple has said that it is appealing the Beijing ruling.
"IPhone 6 and iPhone 6 Plus as well as iPhone 6s, iPhone 6s Plus and iPhone SE models are all available for sale today in China," Apple said in a statement Friday. "We appealed an administrative order from a regional patent tribunal in Beijing last month and as a result the order has been stayed pending review by the Beijing IP Court."
