Patent infringement fraud

Let him sell it. You collected and sold the evidence of your patent and the fact that the product used your patent.

If they sell enough, they can sue for compensation from producers and sellers, as well as royalties.

In addition, I personally think that since you are a partnership, it should belong to the processed products or your enterprise.

Patent sales are under the permission of the whole enterprise. If not, I'll settle it for you.

That's not the external circulation of the enterprise, or that person pretends to be a partnership enterprise qualification and infringes on the interests of the partnership enterprise (that is, you can't get a commission, because it doesn't count as the products of your enterprise, but only issues invoices on behalf of that individual).

And the production enterprise infringes your personal patent.

Then this individual is likely to be suspected of a criminal offence and infringe on the business secrets of the enterprise as a shareholder for personal gain.
