424.     Patents, trade marks and royalties.

Patents, trade marks and royalties which belong to a bankrupt pass to his trustee1. If a patentee becomes bankrupt and his patent is sold by the trustee, the patentee is not afterwards estopped from alleging that the patent is invalid or otherwise impugning it2.

A trustee in bankruptcy may register title to the patent3. The trustee may assign a registered trade mark with or without an assignment of the goodwill of the business, provided that the mark does not become deceptive in consequence4.
