Cromford's technological advantage became an international prize. Arkwright's water frame and later water-powered carding machinery transformed cotton spinning, and he protected the system through patents and licensing. But the machinery's secrets did not remain in Britain: Samuel Slater, an apprentice of Arkwright's backer Jedediah Strutt, carried knowledge of Arkwright's technology to Pawtucket, Rhode Island, where he founded the American cotton industry. The episode became one of the era's most consequential acts of industrial knowledge transfer, helping reproduce the Cromford model overseas. Arkwright's own legal position was also unstable. His patents were challenged in court, and his second patent was ultimately overturned on the grounds that it contained no originality. Despite the defeat, his factory system had already been widely copied in Lancashire, Scotland, Germany, and the United States, making him Britain's wealthiest untitled person by his death in 1792.
