This ruling removes near-term dismissal risk and allows MPWR's patent case to advance to jurisdictional discovery. Monitor for evidence of WT Microelectronics' Delaware contacts during discovery, which could strengthen MPWR's enforcement position. The case is in early stages — no damages or injunction are imminent, but the ruling signals the court is taking MPWR's claims seriously.
