"TPL continues to make significant investments in the design, development, and marketing of MMP-based products (including embedded processors and development boards used in wireless consumer electronic devices and components thereof and products containing the same) under the OnSpec brand"

So if PTSC is half owner of the MMP and TPL is using the MMP to develope more products, I would interpret that as PTSC owning Part of What TPL Builds.

Sound like a future legal battle to me, I hope these guys will work it out.
