This will guide the process you'll use to apply for the patent. 4. File a provisional patent application. This offers a layer of protection in case someone later claims they had the idea before you did. As Issie Lapowsky points out, U.S patent law is a first-to-file system, not first-to-invent.
Ancient River Valley Civilizations Introduction. The term civilization separates cultures that were more developed and settled than the previous hunter-gatherer societies. The first civilizations arose around 4000 BC in four river valleys across the globe. This unit is designed to examine the rise of these early civilizations and the emerging social complexity of populous societies.
Civilization first developed in the Indus River valley in present-day Pakistan in the middle of the 3d millennium B.C., more than a thousand years earlier than it did in China. In fact, the civilization of the Indus valley, usually called Harappan after its chief city, rivals Sumer and Egypt as humanity's oldest. But like Sumer and its successor civilizations in the Middle East, Harappan civilization was unable to survive natural catastrophes and nomadic invasions.
