Assuming en banc is denied in next few days, Sprint will likely file a cert petition within the allowed 90 days. I expect the cert petition to be denied after the Supreme Court's first conference of the next term or about on October 9. Even if T-Mobile is successful in its (Alice, Section 101) invalidity argument against the Prism patents, that decision would almost certainly come after October 6 given oral argument is not until June. Of course, Sprint will move before the district court, Federal Circuit and Supreme Court to try and delay until after the T-Mobile decision, but all of those motions are very likely to be made and denied in the next 2 to 3 weeks. In my opinion, at this point Sprint is just throwing a few Hail Mary passes.
