Final answer:
Louis Le Prince's US patent focused on the specific method and apparatus of his motion picture camera, while his British and French patents covered the general concept of a camera that could capture and project moving images.
Step-by-step explanation:
The difference between Louis Le Prince's US patent compared to his British and French patents
The difference between Louis Le Prince's US patent and his British and French patents lies in the scope and legal protection offered by each patent. The US patent, granted in 1888, outlined the specific method and apparatus of Le Prince's motion picture camera, providing him with exclusive rights in the United States. On the other hand, Le Prince's British and French patents, granted in 1886 and 1887 respectively, were broader and covered the general concept of a single-lensed camera that could capture and project moving images.
This difference in scope and specificity is why the US patent is often considered more important in the history of cinema, as it protected the specific invention of Le Prince's camera.
