[Monterey2000]

Does anyone know if these are the same patents litigated in the UK trial and currently under appeal? I assume the US patents in the US Federal court and ITC cases are different patents and are NOT standards essential patents (SEP).

The patents-at-issue are U.S. Patent Nos. 10,250,877; 8,674,859; 9,674,556; 9,173,054 and 8,737,933.

I know the UK case asserted European patents. The UK case patents litigated are shown below.

The patents asserted are:
European Patent (UK) 2 363 008 – Enables the efficient control of carrier aggregation in 4G (LTE). In advanced mobile phones, carrier aggregation is key to achieving high data rates.
European Patent (UK) 2 557 714 – Supports the use of multiple antennae transmissions in 4G (LTE). The patent enables the use of flexible levels of error protection for reporting by the handset, increasing the reliability of the signaling.
European Patent (UK) 2 485 558 – Allows mobile phone users quick and efficient access to 4G (LTE) networks. One of the main technological challenges of developing LTE networks was efficient bandwidth usage for various traffic types such as VoIP, FTP and HTTP. This patent relates to inventions for quickly and efficiently requesting shared uplink resources — for example, reducing lag when requesting a webpage on a smartphone on LTE networks.
European Patent (UK) 2 421 318 – Decreases latency during HSUPA transmission by eliminating certain scenarios in HSUPA where scheduling requests may be blocked. A blocked scheduling request may prevent a smartphone from sending data.
