Inventorship sounds like a pretty easy topic to grasp and thankfully, it is.

Simply put, the inventors are the individuals who invented the subject matter in the application. They conceived of the idea and either reduced it to practice on their own, or had someone else reduce it to practice for them. A single individual or a group of people may hold the inventorship.

Corporations or other such entities can never qualify for inventorship, only the people within these entities can be the actual inventors.

However, there is a difference between the inventorship and the ownership of a patent. While corporations may not be labeled as inventors, they may own the rights to a patent.

In instances where joint inventors are responsible for inventing the subject matter, the joint inventors may have worked as a team or entirely isolated from one another. One inventor may have worked on one aspect, while another focused on an entirely different aspect of the invention. They needn't have even known each other at the time they were developing the invention.
