The Prior Art Search Challenge
It is difficult to identify novelty of an invention without a thorough understanding of previous work in the field. Prior art search is essential to define the boundaries between a potential invention as claimable in a patent and the published prior art. It is common practice to perform keyword-based and/or classification-based searches of the disclosed concept. Getting a comprehensive result including hidden or unexpected prior art using classic methods is challenging, particularly when working under time constraints. The quality of the search greatly depends on how much time is spent on the search, and on the technical background and skill of the searcher.
