Joint patent ownership occurs when more than one person can claim ownership over a single patent. Each joint patent owner has rights pertaining to licensing, selling, and using the patented item in question.
What Is Joint Patent Ownership
When multiple people can claim ownership over a single patent, it can be said that they have what is known as "joint patent ownership." Each owner has rights that allow them to do the following with the patented item in question:
When it comes to concerns associated with joint patent ownership, the most significant is that of licensing. This is due to the fact that every joint owner has the legal right to grant a non-exclusive license to any person or entity that they choose to, without having to get permission from the other patent owners. Joint ownership of patents can get quite messy given that there is no single patent owner with the ability to grant exclusive licenses or prevent the others from granting licenses of their own. In fact, when a patent has multiple owners, its very value can be diminished in the perspective of potential buyers and licensees.
Because patent ownership begins with the inventor, according to United States patent laws, issues pertaining to joint intellectual property ownership happens more frequently when dealing with patents that have more than one inventor. It's important to take steps early in the life cycle of an invention to transfer each inventor's patent rights to a legal entity, such as a company, using a written Patent Assignment, if at all possible.
A fully signed copy of this Patent Assignment, which identifies each patent or patent application, should be kept on record with the United States Patent and Trademark Office to provide a solid notice regarding the chain of title for the invention in question to the general public.
Basics of Patent Ownership
Owning a patent on an invention or innovation is important because the patent owner is given specific rights pertaining to the patented item. Under normal circumstances, patent rights remain with the inventor until they are transferred to another person or (more commonly) a legal entity, by way of a written Patent Assignment. This is true even in cases where an employee creates an invention for their employer, in most cases.
It's a good idea to establish who owns the item to be patented before filing an application to patent the item with the United States Patent and Trademark Office to avoid any potential issues in the future. Patent owners can take the following actions once they have patent rights:
- License the rights to use the patented items and collect royalties for its use
- Sell their patent rights to another person or entity
- Pursue legal action in the event that patent infringement has occurred
- Manufacture the patented item
- Sell the patented item
- Use the patented item
It's worth noting that, even if you're the inventor of a patented item, if you do not own the patent on that item, you have none of the rights listed above.
In the United States, the rights pertaining to a patent are established under federal law, but ownership of the patent in question is actually determined by your local state laws. Although the state ultimately has the final say in who owns a patent, changes in the patent's ownership are kept on record with the United States Patent and Trademark Office to provide the public with notice regarding who can claim ownership of the patent in question.
A lot of people are confused when it comes to patent inventorship and patent ownership and believe that these are one and the same. In fact, they are not. A person might be the inventor of a patented item, but have no access to the patent rights associated with the item in question, particularly in cases in which the inventor assigns their rights to a third party, such as their employer. Additionally, a person or business entity might own patent rights on an item even though they are not responsible for inventing it, such as when an employee who invented an item assigns their patent rights to their employer.
