The Deed or Title of a land is what confers ownership.

Land Patent, Deed, First Title Deed, Final Certificate and Land Grants all fall under the same system.

According to Wikipedia: http://en.wikipedia.org/wiki/Land_registration

“In law, land registration is a system by which the ownership of estates in land, is recorded and registered, usually by government, in order to provide evidence of title and to facilitate dealing.

In common law countries, particularly in Commonwealth jurisdiction, when replacing the deeds registration system, title registrations are broadly classified into two basic types: the Torrens title system and the English system, a modified version of the Torrens system.”

According to Wikipedia: http://en.wikipedia.org/wiki/Land_patent

“A land patent is evidence of right, title, and/or interest to a tract of land, usually granted by a government (or in the US the federal, state) to an individual or private company. In the original 13 American Colonies a proprietor would grant land patents. Besides patent, other terms for the certificate that grants such rights include first-title deed and final certificate. In the United States, all property can be traced back to the first title deed and to claims document titles for land originally owned by France , Spain, United Kingdom, Mexico, or Russia.

A land patent is known at law as “letters patent” and usually issues to original grantee, and their heirs and assigns forever. The patent does not constitute title but is mere evidence of right to title existing in law.”

In studying law, you will compulsorily study Real Property. After you do that, you can further take up studies in the field (as part of your optional subjects). Wouldn’t make a conclusion that you want to be a real property lawyer without studying real property itself first.
