The Entire D6 Interview With Intellectual Ventures' Nathan Myhrvold (3 of 3)

We’re posting all the interviews from the sixth D: All Things Digital conference that took place in late May.

But–as many readers have requested–they will all be available in their entirety in this column.

Here is a video of an interview Walt Mossberg did with Nathan Myhrvold, founder and CEO of Intellectual Ventures.

In it, Mossberg wrangles with the former Microsoft (MSFT) CTO and research guru over his controversial company, which is assembling a large body of patents and inventions.

The Wall Street Journal wrote a piece earlier this week about Myhrvold’s efforts, discussing how he is “using that clout to press tech giants to sign some of the costliest patent-licensing deals ever negotiated.”

The video of the interview is in three parts.

In this third part, Myhrvold takes questions from the audience, including about whether Intellectual Ventures is making a patent land grab, putting resources behind inventions to make actual products, patent abuse and making research into a profit center.
