A patent can only be applied for in the name of the actual inventor or co-inventor of the invention. It is not enough to make a financial contribution to a product to be considered the inventor. This is true even if the inventor was employed by another person or company to create the invention. Although an employer will often own the resulting patent, the patent will be issued in the name of the actual inventor. Just because you invented the underlying invention, that doesn’t necessarily mean you own the patent. This is especially true if the inventor’s employment contract contains a pre-assignment clause or if the patent was invented as part of the inventor’s job. In such cases, even though the patent will be issued in the name of the inventor, the employer may have contractual rights to the invention. In fact, if the inventor attempts to sell, license, or use the invention without the employer’s consent, the employer would probably have an action for breach of contract against the inventor.
After that the next question is, Can you patent a process?
So ans is not every invention is eligible for a patent. In fact, some things are specifically excluded from patent law. For example, US law does not provide patents for laws of nature, physical phenomena, abstract ideas, and non-useful objects. However, patents are available for:
A processes or method (business process, computer software or engineering methods)
A machine (anything that can perform a function)
A new composition (make-up, pharmaceuticals or artificial creations)
An article of manufacture (a tool or an object that can get a job done in a few steps)
