They don't seem to have any value listed for Intangible assets , i suppose that's why its net tangible assets only for now.
I guess since its not generating any measurable economic benefit from its IP yet it doesn't really have much quantifiable value.

"For an IP asset to have a quantifiable value, it should: - generate measurable amount of economic benefit to its owner/user."
