Federal Circuit dismisses SSPPU “”rule””

Readers of this blog will know that I’ve frequently questioned the idea that there’s a “rule” mandating that royalty or damages for infringing multi-component products be calculated using a “Smallest Salable Patent-Practicing Unit” (SSPPU) as a value-base. The idea of this “rule” has attracted quite some powerful followers and in February 2015 it was even codified into the new IEEE patent policy (!).

 

 

 

 

 

Well, on December 3, 2015, in an appeal decision in the CSIRO vs. Cisco case, the US Federal Circuit made it crystal clear that no such “rule” exists.
