Reply to comment by Scottland83 in TIL The inventor of the television was a 15 year old farm boy who got the idea for scanning an image in rows from the back and forth motion of plowing a field. by chapstickninja
With synchronized pendulum clocks that could perhaps produce a single halftone document copy in perhaps 10 minutes. Bit of a far cry from producing & transmitting 15-25 greyscale images a second.

But same concept using scan lines and one-dimensional signal.

Certainly the pantelegraph of the 1860's was conceptually a scanning device to output a serial transmission. One could argue by the same logic that taking words in lines on a page, converting & transmitting them as telegraph code serially & assembling the output back into words on a page is the same concept, something Morse & others were doing in the 1840's.
In the end all discovery is seeing a little further by standing on the shoulders of giants. Which means we acknowledge what went before but also acknowledge the thing that makes something patentable i.e.
- Patentable subject matter, i.e., a kind of subject-matter eligible for patent protection
- Novel (i.e. at least some aspect of it must be new)
- Non-obvious (in United States patent law) or involve an inventive step (in European patent law)
- Useful (in U.S. patent law) or be susceptible of industrial application (in European patent law[1])
