hi, new guy here.

I really don't see any significance to such patent. It's like patenting a fork with 3 prongs, even though you can easily find ones with 4 prongs.

Whenever i want to print something bigger than the build area and the part has to be strong enough to support weight, i will split the part and implement the appropriate indentations.
Alternatively i'll just screw in or glue non printed support beams such as wood or metal tubing.
