Due to its worldwide patents, the Coca-Cola Company of the United States used to offer a single flavor variety, a single standard bottle and a unified product before the 1960s.

The Coca-Cola formula did not apply for a patent, but was protected as a corporate secret because the patent protection period is only 20 years.

But as a large international company, there must be other technologies that have applied for patents.

The most famous thing is that Coca-Cola has applied for an appearance patent for its classic glass bottle.
