Synaptics sues Chinese rival Goodix Technology.

• Synaptics (NASDAQ:SYNA) has sued Chinese touch controller/fingerprint sensor IC vendor Goodix Technology and Florida-based smartphone OEM BLU Products for allegedly infringing several Synaptics patents related to touch sensing IP.

• 
  
• Complaints have been filed both with the ITC and a Northern California federal court (a favorite haunt of Silicon Valley companies filing infringement suits). Naturally, an ITC import ban is sought, as well as a cease and desist order for U.S. sales.
• News of the suits comes ahead of Synaptics' Thursday FQ3 report. The company has been battling with low-cost Asian touch controller vendors for design wins with Chinese OEMs; it's counting on its recently-launched TDDI (integrated touch controller/display driver) ICs to maintain a strong high-end share.
