Why should a patentability search be conducted?
It is generally advisable to conduct a patentability search. In the United States alone, there are a large number of patents (over 6,000,000) already issued, arranged in approximately 460 classes and more than 140,000 subclasses. Owing to the large number of patents previously issued, it is possible that an invention may not meet the patentability requirements of novelty or unobviousness due to prior existing patents.
