You did not read the whole article... the patent DID NOT prevail.
You left out a very relevant part of the article:
People rallied to Ford’s side against the bullies. Editorials weighed in against the industry’s heavy-handed lawsuits, and Ford helped his own case by purchasing litigation insurance for his customers. By the time the patent litigation was over – Ford won on appeal in 1911 when the court ruled that the Selden Patent covered only cars made with a special type of engine nobody was using anymore – Ford was a hero, and the largest car manufacturer in America.
