A more accurate title would be "You can infringe a patent even if you didn't do all the steps yourself". This ruling is simply making the common-sense observation that you can't get around a patent by doing some steps with your right hand and other steps with your left hand and then pointing out that neither hand infringed the patent by carrying out all the specified steps.

Flagged for a misleading title. Page 10 explicitly states:
``To be clear, we hold that all the steps of a claimed method must be performed in order to find induced infringement, but that it is not necessary to prove that all the steps were committed by a single entity''
Previously, you either had to perform all of the steps of a claimed method or induce another to perform of all of the steps of a claimed method. There was no remedy available when you perform some of the steps and induce another party to perform the remaining steps.
