Depends how much money you have.

For example, Tesla just patented the Robotaxi one year ago, despite having open-source solutions like Apollo Self-Driving platform.

Patents are really an obsolete system that favors the super-rich and the lawyers.

I'd be surprised if they patented the general concept of a robotaxi. Almost certainly, it'd be one specific type they they could say they invented.
