Is the Invention Patentable?
Prior to filing a patent application, it is advisable to attempt to assess the patentability of the invention by conducting prior art searches covering worldwide publications, including patent and non-patent literature. A registered patent agent can advise you about the types and cost of such searches. Patent and published patent application databases are available over the Internet, some free of charge. They generally offer a comprehensive and readily accessible source of patent information. Database searches are generally dependent on key word input, accordingly, it is important to understand the nature and scope of the invention. Whatever the technique used for conducting a search, it is important that the search results be carefully analyzed and the differences between the invention and prior patents appreciated. Registered patent agents have the expertise and skills necessary to properly carry out effective searching and to make such an analysis to provide patentability opinions. It is also noteworthy to acknowledge that patent literature is only published 18 months post filing, and thus may later be discovered as relevant prior art though not searchable prior to filing of the projected application.
