Prior Art

Prior Art is arguably the most critical concept in the patenting process. It encompasses all information that has been made available to the public in any form before a given date that might be relevant to a patent's claims of originality. If an invention is described in the prior art, it is not considered novel, and a Patent cannot be granted.

The scope of prior art is vast and global. It includes existing patents and published patent applications from any country. Crucially, it also includes non-patent literature such as scientific journals, academic papers, magazine articles, public demonstrations, products already on the market, and even public internet pages or YouTube videos.

During the examination of a patent application, the USPTO examiner will conduct an extensive search of the prior art. They use this information to evaluate two main criteria: novelty and non-obviousness. If the exact invention is found in a single piece of prior art, the invention lacks novelty. If a combination of prior art references would make the invention obvious to someone skilled in the field, it lacks non-obviousness.

Inventors are legally obligated to disclose any known prior art to the USPTO through an Information Disclosure Statement (IDS). Failing to disclose relevant prior art that the inventor is aware of can lead to severe consequences, including the patent being declared unenforceable due to inequitable conduct.

Because prior art is so definitive, conducting a thorough prior art search before drafting a Non-Provisional Patent Application is highly recommended. A professional search helps inventors understand the landscape, refine their Claims to avoid existing technology, and save time and money by not pursuing a patent for an idea that is already public knowledge.
