The content protection/digital rights management company Widevine is suing Verimatrix, one of its major competitors for patent infringement based on Widevine's patent for selectively encrypting different portions of data sent over a network. Widevine has offered Verimatrix the opportunity to license its selective encryption patent, but Verimatrix has not responded.
Verimatrix denies Widevine's claims and states that it will vigorously defend itself.
Both of these companies have done well in the IPTV market. The preliminary conclusions from our report "Opportunities in TelcoTV" are that Verimatrix appears to be in a stronger position today because it has been included in the IPTV service of more major telcos than Widevine. This report will be released by the end of this month.

Verimatrix's patent portfolio has been ordered into reexam by the USPTO. It seems that prior art has been located that raises "Substantial New Question" about the patentability of VCAS. Control number 90/010,028 in the USPTO system.
