Exhibit 99.5

FotoNation Customer Email for DTS Acquisition

Dear Name,

I’m very excited to let you know that earlier today, Tessera announced that we will acquire DTS (Nasdaq: DTSI), a global leader in premium audio technologies. The new company combines market leading audio and imaging innovators with complementary products, technologies, customer channels and intellectual property assets to enable the creation of an expanded, integrated platform to invent the future of smart sight and sound.

This transaction will enable us to offer a combined complementary technology portfolio that is ideally suited to deliver the next generation of solutions to the mobile, consumer electronics, and automotive markets while expanding our ability to address incredible new opportunities in IoT and AR/VR. Upon completion of the acquisition, the combined company will be one of the world’s leading product and technology licensing companies, with over 450 engineers focused on developing next-generation imaging, audio and semiconductor packaging and interconnect technologies.

I look forward to providing further insights into this development the next time we get together. As always, we value our relationship and look forward to working together moving forward.

Best regards,
