NanoViricides Inc. (NNVC)

Considering that none of Diwan, NNVC, Theracour, or AllExcel have filed any patent applications since 2006, it might all be theoretical.

After $63M and ten years, nobody has managed to come up with anything worthy of patenting. It may be the God's blessed Diwan only once, some time in 2005, when they revealed the cure for almost the totality of all know viral infections.

However...

You're right about it being usual practice for companies to have their employees agree to assign any IP they invent to the company as part of their employment agreement.

U.S. patent law says that every inventor has an equal and undivided right to the entire patent, and those rights pass to their assignees.

Regarding Diwan, who knows. Considering that he acts in his own self-serving interests contrary to NNVC shareholders, I'd wager he hasn't signed away any of his rights so that he maintains rights personally.

I still think the oddest thing about this is that nobody has registered the assignment from AllExcel to Theracour. There are a number of important reasons why the licensee and its shareholders would want that to be done.
