This note describes the attempt by a Polish trading company to increase its capital value by issuing shares based on the value of its assets. These assets included a trade mark which, once entered on the company's books, was then the subject of an exercise in depreciation. Following litigation up to the District Administrative Court level it was held that only trade marks that have been registered can be depreciated: in this case, it appears, the trade mark was only the subject of an application, but it is the act of registration itself that establishes its status.
