We start with the parties involved and how their trades interrelate. The first appellant and the plaintiff in the suit below, Sandipala, produces personalised electronic identification cards. The second and third appellants, Mr and Ms Tannos, are father and daughter and are Sandipala’s directors. They are responsible for most, if not all, of the decisions involving Sandipala. The first to third respondents were the defendants in the suit below. The first respondent, STMicroelectronics Asia Pacific Pte Ltd (“ST-AP”), sells microchips, which we will refer to simply as “chips” below for convenience. These chips can be used by companies like Sandipala to produce electronic identification cards. The third respondent, Mr Vincent Pierre, Luc, Cousin (“Mr Cousin”), is ST-AP’s country manager in Indonesia. The second respondent, Oxel, also supplies and sells chips for use in electronic identification cards. Unlike ST-AP, which produces the hardware, ie, the physical chip, Oxel supplies the software for the chip, ie, its operating system. The chip produced by ST-AP is encoded with Oxel’s software. When the chip is produced and encoded, Sandipala uses the completed chip to produce the physical electronic identification cards.
