Johnson and I discuss obviousness determinations built on excessive combinations of prior art, warning that such analyses blur the line between legitimate hindsight reconstruction and genuine innovation assessment. We also highlight a systemic blind spot: nuisance "ankle-biter" assertions that exploit litigation economics while largely evading PTAB scrutiny. These cases have driven much of the political backlash against patents while remaining functionally untouched by the post-grant review process.
