I'm not so sure. It's a fact that he was involved in the development of this new feature, and it's his opinion that he originated the idea. Whether he did or not is for a court to decide, but he's not committing perjury by believing this.

Now if he knows he didn't originate the idea and has brought vexatious proceedings, then sure, this may be perjury, but we are some way off knowing this, and i don't think we'll be in a position to determine this either way.
