Right. It’s best to think of the claims in a patent as a set of DAGs (a single patent can contain multiple “inventions”). To infringe, you have to go from a starting node to a connected ending node and implement/match all nodes along the path.
Have to admit I've never heard this in my life. If this is the case, then TIL, thanks!
I will say that my point largely stands, though: the leaf nodes of this particular DAG are places where you will almost inevitably end up if you want to implement robotic farm machinery. Deere averages a couple hundred patents a year, so if you don't step on this specific land mine, another one will get you.
