§ 153 Kinds of Property
All property is, as we have already seen,409 either corporeal or incorporeal. Corporeal property is the right of ownership in material things; incorporeal property is any other proprietary right in rem. Incorporeal property is itself of two kinds, namely (1) jura in re aliena or encumbrances, whether over material or immaterial things (for example, leases, mortgages, and servitudes), and (2) jura in re propria over immaterial things (for example, patents, copyrights, and trade-marks). The resulting threefold division of property appears in the following Table:—
| Property | Jura in re propria | Material things | Land | Corporeal property |
| Chattels | ||||
| Immaterial things | Patents | Incorporeal property | ||
| Copyrights | ||||
| Trade-marks | ||||
| &c. | ||||
| Jura in re aliena | Leases | |||
| Servitudes | ||||
| Securities | ||||
| &c. | ||||
