Patenting core 70s, 80s and 90s computer graphics techniques in the 00s
This is how the Commodore 64 and other tile-based computers of the 80s and 90s performed scrolling.
They didn't do any memory copying (as per the patent), they drew onto the newly uncovered area of the screen (as per the patent, arguably even more advanced because the computers had off-screen areas of tile to load into before the scroll) and so on. They rendered the tiles from a tile cache (the graphical characters or bitmaps), as per the patent. They could smooth scroll (by scrolling by fractions of the tile's width or height). It was handled in hardware, not software, but that's because modern software is more advanced.
The entire concept is trivial. There is no way they spent millions developing it. You get any software engineer, posit the problem, and they'll come up with a similar solution.
