Three Basic Criteria For Getting a Patent

To get a patent, your invention must be new and non-obvious. In other words, you must incorporate an element that no one else has thought of before. An example of a non-patentable invention is mixing two colors of paint. Other categories of patentable inventions include articles of manufacture, machines, and processes. In contrast, non-patentable subject matter includes natural processes, theories, and body movements.


In order to be eligible for a patent, your invention must not be obvious to someone with ordinary skill in the art. This standard is known as non-obviousness, and it ensures that your creation is not a logical evolution of prior art. To determine whether your invention is non-obvious, the USPTO looks at the relevant prior art, or prior works of art, and will consider whether or not it is a logical evolution of that prior knowledge.

Once the applicant has demonstrated that his invention is not obvious, he must submit evidence of this to the Patent Office. This can be evidence in the form of an affidavit or declaration. It is important to note that the evidence must show a direct connection between the claimed features and the consideration. While this evidence must be objective, it is possible that your invention is commercially successful, for example, because it was marketed in a way that a competitor did not.

Another factor that can be used to determine whether an invention is obvious is its practicality. This principle applies to many inventions that may be rejected due to obviousness. Therefore, the inventor should present a strong initial case of non-obviousness in the patent application, and the examiner should have the opportunity to argue the validity of the invention if the patent is refused. It is important to note that this criteria does not apply to every single invention.

Another important element is market evidence. This evidence is much more reliable than abstract principles. Patent examiners are not allowed to consider market evidence for a product, but they can find it during an infringement dispute. A patent may not be valid until after it has been in use for several years. For this reason, the examiner should carefully review all patent applications and consider the evidence for non-obviousness.

When deciding whether an invention is not obvious, it is essential to consider whether the creation would have been made by an ordinary person without any prior knowledge. The criteria for patentability are complicated, but once the patent office has been satisfied, the patent will be granted. However, it is possible to overcome this obstacle by making it more obvious than the competitor’s. Once the court has approved the patent, the applicant will be able to market the product to the world, and the invention will be protected.

Whether an invention is obvious is a legal question that requires the Office to explain in detail why it is not obvious. It is important to remember that the ultimate determination of non-obviousness is a legal conclusion, but the underlying factual inquiry is a factual one. Findings involving the state of the art, teachings of references, and ordinary skill are crucial for establishing the patentability of a new invention.

Non-patentable subject matter

There are three main categories of patentable subject matter. These categories include inventions that have a functional purpose and those that aren’t. Examples of non-patentable subject matter include books, music, data structures, electromagnetic signals, and laws of nature. A patent cannot be issued for a “purely abstract” idea. In the U.S., however, an invention can be patentable if it meets all three criteria.

First, an invention must be “non-obvious.” In other words, it must be an improvement over an existing invention. It also needs to contain some element that no one else has yet thought of. A paint color mixer, for example, would not be patentable. Other patentable subject matter includes articles of manufacture, processes, and machines. It also includes composition of matter. Non-patentable subject matter includes theories, natural processes, and human body movements.

Patentable subject matter must be a useful invention that has a practical application. Some countries prohibit certain subject matter from being patentable, such as business methods. In order to be patentable, the invention must be a product, process, or a method, and must relate to a field of the manual or productive arts. Further, the invention must be capable of causing a physical effect, which is distinguishable from an abstract idea.

The term of the patent must be at least 10 years. The scope of patent protection is determined by the terms of the claims and the interpretation of the description and drawings. In addition, the invention must be available to the public. If the patent is granted after the invention is disclosed, compensation for unlawful exploitation must be limited to the subject matter of the patent. This means that compensation is based solely on the subject matter covered by the patent.

A patent can’t protect the originality of an idea if it isn’t useful to others. In addition, the invention must also be useful and claim originality. Unlike many laws in other countries, patent law allows only the first applicant on the file to obtain a patent. In some countries, however, it is also required before the product can be made public. Therefore, it’s imperative to seek legal advice from a patent lawyer as early as possible.

The third and final requirement for patentability is that the invention be unique and not existing before it was invented. Patents cannot cover inventions that were previously patented. Biological material that is essential to the process isn’t considered patentable. Biological material that isn’t used in a practical way may also be patented as a utility model.

Another example of non-patentable subject matter is algorithms. For example, an algorithm that converts binary-coded decimal numbers into pure binary numbers is considered non-patentable. The Supreme Court in Gottschalk v. Benson considered an algorithm to convert binary-coded decimal numbers into pure binary numbers. The Court also emphasized that abstract mathematics and computer software are not patentable subject matter.


First, your invention must have utility. To qualify as useful, it must be new, different, and inventive. The PTO has specific guidelines on defining utility. Generally, a utility assertion must be credible, specific, and based on substantial evidence. Further, the invention must be useful in the present, not some future day. To satisfy utility requirements, your invention must have tangible utility to the public.

The utility patent is issued for inventions that create a new useful process, machine, or composition of matter. It allows the owner to exclude others from making, using, or selling that invention. The term is twenty years, with extensions of up to five years allowed for drugs, medical devices, and additives. Design patents last only fourteen years. The application should also state whether or not the invention was made as part of a federally-funded research grant or intramural program.

The term “patent” comes from the letters “patents”. During the Middle Ages, sovereign entities granted patents for special privileges. The first recorded patent was given to Filippo Brunelleschi in Florence, Italy, in 1421 for an industrial invention. Since then, countries have established their own rules on how to apply for and grant patents, including the number of years a patent can last, types of patents, and filing rules.

The claims in a patent application are the most important part of the document. These claims should cover the invention as broadly as possible without straying too far from the requirements for novelty and utility. The content of your invention must teach other people how to do it. Besides, patents cover material that has utility or a useful purpose. However, there are many exceptions to this rule, and you must consider this carefully.

Finally, you must meet the novelty requirement. The most important part of the patent application is whether or not your invention has novelty. To be patentable, your invention must be useful. Usefulness is a general requirement, but is usually fairly easy to meet. Furthermore, it must improve upon another similar invention. The patent agent will consider all prior patented inventions, including similar versions, and will refuse to grant your patent if all of these features are already in a prior patent.
