Short answers, pulled from the story.
The Jumpman logo was crafted by Nike shoe designer Peter Moore. Moore came across a Life magazine photo of Michael Jordan taken by photographer Co Rentmeester at the University of North Carolina at Chapel Hill campus and had Jordan replicate the pose in Chicago wearing his Bulls uniform and Nike Air Jordan shoes.
The Jumpman logo is based on a pose identical to the grand jeté ballet technique. Jordan originally performed the pose for a Life magazine photo shoot before the 1984 Summer Olympics, holding a basketball in his left hand.
The Jumpman logo was introduced in 1988, appearing on the third version of the Air Jordan shoes. It became the logo for Nike's Jordan brand in 1997.
No. Rentmeester filed suit against Nike on the 22nd of January 2015 in a federal court in Portland, Oregon, claiming copyright infringement. The judge ruled against him in June 2015, and a U.S. appeals court upheld that decision in February 2018.
On the 8th of April 2020, after eight years of legal battle, Jordan prevailed at the China People's Supreme Court, which revoked 74 trademarks belonging to Qiaodan Sports. The court ruled that unauthorized registration of a person's name as a trademark misleads the public into assuming endorsement, violating Article 31 of China's Trademark Law.
Drake and Future titled a song "Jumpman" after the logo and mentioned the brand multiple times in its lyrics. Guitarist Buckethead also released a composition called "Jordan" that referenced the Jumpman logo on its single cover.
