I predict a high chance that they lose this patent. Mark my words.

According to patent prosecution records, the independent claims for GB2484736 originally lacked any network transport limitations and were deemed entirely unpatentable against the prior art listed above.

To get the patent granted, DisplayLink’s attorneys amended the claims to specifically add delivery of the display data over a "general-purpose data network." The validity challenge relies on proving that adding a general-purpose transport layer (like USB or Ethernet) to existing image-compression methodologies was an obvious step and completely unoriginal in 2010, given the widespread existence of USB monitors and network-attached graphics at the time.
