Only the following may be included in the pledge subject to the provisions of this chapter as forming part of a business: the sign and trade name, the right to the lease, the clientele and goodwill, the business furniture, the equipment or tools used in the operation of the business, the patents, licences, trade marks, industrial designs and models, and generally the intellectual property rights attached thereto.
A certificate of addition subsequent to the pledge which includes the patent to which it applies follows the fate of that patent and forms part, like it, of the pledge constituted.
In the absence of an express and precise designation in the deed constituting it, the pledge only includes the sign and trade name, the right to the lease, the clientele and the goodwill.
If the pledge relates to a business and its branches, the latter must be designated by a precise indication of their registered office.
