HTC Corporation v Gemalto SA [2014] EWCA Civ 1335 (22 October 2014)

HTC Corporation v Gemalto SA [2014] EWCA Civ 1335 (22 October 2014)

The term 'microcontroller' in the patent claims is limited to a single chip with at least some on-chip memory (other than registers and cache), and does not encompass systems with all memory off-chip. On this construction, the HTC devices do not infringe claim 3. Claim 3 is entitled to priority because the priority document discloses the general idea of compaction, not limited to a specific method.
