The act of becoming the owner of certain property; the act by which one acquires or procures the property in anything. Used also of the thing acquired. Original acquisition is where the title to the thing accrues through occupancy or accession, (q. v.,) or by the creative labor of the individual, as in the case of patents and copyrights. Derivative acquisition is where property in a thing passes from one person to another. It may occur by the act of the law, as in cases of forfeiture, insolvency, intestacy, judgment, marriage, or succession, or by the act of the parties, as in cases of gift, sale, or exchange.
