Invention ideas are different than ideas that are not patented. They can be cultural, commercial, or technological in nature. Invention ideas are the seeds for new business or products. The next step is conceptualizing the idea. This step requires brainstorming different solutions to a problem and considering several options. If your idea is commercially viable, you might want to consider patenting it.
Inventions are cultural inventions

Cultural inventions are inventor ideas and behaviours developed and perpetuated by groups of people. The ideas and behaviours are often handed down through generations. These inventions include things like language, music, and art. These cultural inventions are important because they make our lives better and help us stay connected to each other.

Inventions often begin as rough drafts, sketches, or experiments. They are often not fully realized ideas, but they become a part of culture.
They are technological inventions

Some of the most important technological inventions in history were invented by someone with an idea. For instance, the Bessemer Process led to mass production of steel that today is used in everything from skyscrapers to bridges. Another example is the transistor. Julius Lilienfeld patented the field effect transistor in 1926, which became an essential piece of circuitry in nearly every modern electronic gadget.

These technological inventions have shaped civilizations throughout history, and have shaped life on Earth. From the wheel to the Mars rover, humans have invented a variety of useful products. In fact, most major inventions did not have a single inventor; instead, several individuals have contributed to their development.
They are commercial inventions

Inventions are the lifeblood of every modern society and many of the world's largest companies were born from one great idea. IBM emerged from a company that sold mechanical census-counting machines, and Sony made its name by selling cheap transistor-based radios. Goodyear, the tire company, is credited with its invention of durable, "Vulcanized" rubber, and AT&T can trace its roots back to the invention of the telephone by Alexander Graham Bell in 1876. However, today's companies cannot survive on a single great idea alone.

Some of the most popular commercial inventions came from inventors working on the same problems as ours. In addition, some inventors had different ideas, so the dates are often disputed. Furthermore, some inventions were patented by several inventors at the same time and were eventually improved by a third inventor. To resolve such ambiguity, the date of the first working version of an invention is usually used. For example, Lothal dockyard was constructed in India between 2400 and 2000 BC.
They are patentable

Patents are granted by the federal government to enable people to make a profit from their inventions. However, there are strict rules about what constitutes a patentable idea. Inventors must prove that their ideas are truly novel and not merely variations on a prior art idea. In order to receive a patent, an idea must be turned into a working prototype or a blueprint.

An invention must be novel, unique and non-obvious. This means that the inventor ideas must be the first person to develop it. Moreover, it must be fundamentally different from previous inventions, and the inventor must be able to describe how his invention works.
They are marketable

Whether or not an inventor idea is marketable depends on several factors. First, the idea should be useful, saving people time and money. Second, the invention should be priced appropriately, otherwise it will be difficult to implement the idea at a profit. Third, the inventor's idea must be appealing enough to appeal to enough buyers to be considered marketable.

Fourth, the inventor should be willing to try out a wide variety of ideas. For example, an engineer with 25 years of experience in the aerospace industry came up with a medical device that had nothing to do with his background. Inventors should also be flexible in their approach and remain steadfast in their pursuit of their dreams.
