The father corroborated this, and the incorporation proceeded with the younger Pemberton joining Candler and Woolfolk Walker as the principals.
With Candler and Walker soon at odds with Charley Pemberton, his father announced that it was the rights to the Coca-Cola name but not the formula that he had conveyed to the son.
Though he remained a shareholder in Coca Cola Corporation, the son left the company in the summer of 1888, and began selling a lower-quality version of the beverage, under the name Coca-Cola.
In the same year, Charley Pemberton died at the age of forty, after an apparent overdose of opium, as he was probably addicted to it like his father.
The Coca-Cola Company remained vulnerable, until the inactive Coca Cola Corporation's charter expired in 1908, to legal challenges from it.
