Trouble arose between R3 and Ripple Labs in September 2017 when R3 filed a lawsuit against Ripple in Delaware and New York. R3 claimed that Ripple violated a purchase agreement for XRP tokens between the two companies. The agreement included an option for R3 to be able to purchase up to 5 Billion XRP at a price of $0.0085 before the end of 2019.
In October 2017 a Delaware judge dismissed the case and R3 was forced to continue litigation in California and New York.
Ripple filed a counter claim against R3 in California accusing R3 of violating several commitments within the agreement. At the time of filing the total value of the tokens in question was approximately $1 million, but within several months during the winter crypto boom that became a staggering value of $3.85 billion.
A San Francisco state appeals court denied Ripple's appeal to the order that dismissed its lawsuit against R3 in March 2018.
