Issue(s) Presented

“I. Network-1’s Appeal A. Independent Basis for Verdict: Does the evidence compel a finding of non-infringement irrespective of the challenged constructions? B. Claim Construction: 1. Did the district court properly construe ‘low level current’ to mean ‘a non-data-signal current that is sufficient to begin the start up of the access device but that is not sufficient to sustain the start up’? 2. Did the district court properly construe ‘main power source’ to mean ‘a DC power source’? II. HP’s Cross-Appeal A. IPR Estoppel: Did the district court err in concluding that HP is estopped from presenting its obviousness challenge to all the asserted claims? B. Claim Broadening: Are the asserted claims invalid as a result of Network-1’s improper claim broadening during reexamination?”
