Should there be limits for patent lawsuits?

Virgin has now won the n’th lawsuit from Rovi on EPG application in their boxes/network. Also Ziggo won cases against Rovi.

Rovi (previous Gemstar) is the self declared king of EPGs supported by many patents, now found to be frequently invalid. But they just keep on coming at you, which is what many organizations fear; and they just pay up. Just when turns “trying to get your rights acknowledged” turn into extortion, if only for the legal costs involved.

Rovi loses yet another patent case

Rovi lost cases in the past against Ziggo and Virgin cable. It tried again with another lawsuit which it it now has lost again. The details of the verdict are interesting in the sense of getting a glimpse on the typical subtleties in patent cases.

Rovi has been permitted to refine it’s main patent claim (probably on grounds the original was too wide). Ziggo has argued that the new claim does not apply to it’s EPG; since it requires a (technical) integration between the favourite list and the EPG, where the favourite list is composed/adapted in the EPG. The court agrees with Ziggo that it’s product merely permits to constrain the EPG to favourite channels, i.e. does not violate the Rovi patent claim.
