TQ Delta, LLC v Zyxel Communications UK Ltd & Anor [2019] EWHC 353 (Pat) (19 February 2019)

The trial should be fixed for September 2019 as further delay would be prejudicial to TQ Delta, the issues can be managed within a ten-day trial, and the court will not accommodate excessive estimates for cross-examination or preparation. Amendments to TQ Delta's pleadings regarding essentiality analysis are permitted, but admission of Dr. Nedev's revised expert evidence will depend on its content, proportionality, and impact on trial length.
