OpenAI has responded to Apple's trade secret lawsuit by releasing iMessage conversations involving former Apple engineer Chang Liu. According to The Decoder, these messages reveal Apple employees reaching out to Liu for technical assistance and access to internal documents after he had left the company.

This move by OpenAI appears to challenge Apple's claims by highlighting ongoing contact between the ex-employee and his former colleagues. The release of these communications could play a significant role in the unfolding legal dispute between the two tech giants.

For Japanese investors, this case underscores the increasing legal complexities in intellectual property and talent mobility within the global tech sector, which may influence market dynamics in both equities and technology-related assets.
