51 results about "Subdivision" patented technology

Subdivision is the act of dividing land into pieces that are easier to sell or otherwise develop, usually via a plat. The former single piece as a whole is then known in the United States as a subdivision. If it is used for housing it is typically known as a housing subdivision or housing development, although some developers tend to call these areas communities.
