An inventor spends money, time and ‘intellectual energy’ on developing a particular product. Now after spending so much time working hard to develop the product you would want to reap the benefits of your hard work. Hence, invention patent is something, which you should consider very seriously. If you have a look at the U.S, patent law an inventor is a person who contributes to the claims of a patentable invention. Now there may be various people involved in the invention of any item. The U.S laws say that the patent is the right of the person who provides the intellectual domain. Merely assisting in the process doe not mean anything. There can of course be joint inventors or co inventors. Patent is something which is extremely important as it helps people to protect there creation. Now if someone else wants to use know- how and learn something from it he will have to compensate the inventor in someway.
The inventor may license the product to the entity for an up front fee or an ongoing royalty. He can also sell the patent outright. A good example of an inventor selling his product is Henry Woodward sold is U.S patent on light bulb to Thomas Edison who then developed it into a commercial success. Now if you have created something and you want to protect your discovery you could approach a patent attorney. He is a person who specializes in represent clients for obtaining patents. He also acts in all matters obtaining to the patent. Some times he may also have to file cases in case if he feels someone has used it without obtaining permission. In some places, they are referred to as patent agent, or patent lawyer. However, they perform the same function of obtaining patent rights for the client and protecting it.
