The invention process is usually a systematic process throughout the entire manufacturing and technological development process. It can be an innovation for building an improved machine or item or a creative process for producing a new material or an end-product.
The most common inventions are those that have already been made. Examples include the sewing machine, the telephone, television, radio and the washing machine. These inventions were created by people that were either already doing what we now call those things or were able to see an existing product and imagine how it could be made better or easier. An example of this would be the sewing machine. While many people still use sewing machines today, some people never had one as we know it. Others, such as Thomas Edison, saw an issue in the textile industry and invented the sewing machine.
Many scientific methods have been invented over the years. Some examples include the microscope, the electric lamp, radio, television, and the light bulb. The light bulb is probably the most well-known example of a scientific invention. It allowed people to work at night without relying on artificial light.
Generally, an invention must do what has been previously done or be able to create something new. Often, an invention only requires further development to make it commercially viable. For instance, the electric generator we use today was originally developed by German scientists to supply electrical energy to hospitals during power outages.
Other types of inventions fall into what is known as a curative process category. This includes devices that prevent or heal diseases. Examples of this include penicillin, vaccines, insulin, blood thinners, artificial skin disease, angiogenesis, and bone grafting. The curative process category sometimes includes therapeutic inventions that benefit the public. Such examples include hearing aids and braces.
An invention can only be patented once it is “invented.” In other words, someone must first demonstrate to a significant degree how their invention works or will work before they can patent it. For example, the patent office will consider whether the claimed invention actually solves a problem, creates a product that solves a problem, or makes a product that solves a problem. The first time someone demonstrates how an invention functions, they can patent the invention. They don’t have to prove that the invention is new, although in some cases a patent application will request that evidence.
