CommScope v SOLiD Technologies [2022] EWHC 769 (Pat)
This was a patent infringement action relating to digital antenna systems (“DAS”). The patent was for a digital DAS, in which the internal handling of the analogue RF signals is digitised. The judge, Mellor J, criticised the claimant’s expert witness, who he characterised as having had significant experience of the US patent litigation system, and as a result significant difficulty adjusting to the rules applying to the giving of expert evidence in the UK. He went on to hold claim 1 of the patent to be anticipated, and the other allegedly independent claim to be obvious.
Hugo Cuddigan QC and Edward Cronan acted for the successful defendant, SOLiD Technologies.
