A patent search can help an inventor to determine whether it makes sense to pursue patenting an idea. Not only can a determination be made of whether the idea is novel and non-obvious, but a search often helps an inventor to expand an invention, by becoming more aware of the state of the field.


A provisional application is a legal document filed in the United States Patent and Trademark Office, that establishes an early filing date, but which does not mature into an issued patent unless the applicant files a regular non-provisional patent application within one year. We advise clients to file a provisional application in order to give the inventor time to further refine the invention or even to seek investors before continuing into the production phase.


A complete nonprovisional application differs from a provisional in that it must contain at least one claim to be examined by the United States Patent and Trademark Office. A nonprovisional application may also claim priority to a previous application, which is not permitted with provisional applications. When prosecuted properly, this type of application has the potential to ripen into a registered patent.


After an initial examination of a nonprovisional application, an examiner will issue what is commonly referred to as an Office action. This is typically a rejection or a request to amend the claims of the application. Our patent attorneys can assist you in adequately responding to these Office actions, and maximizing your chances of receiving a registered patent.


A patent application filed under the Patent Cooperation Treaty (PCT) is called an international application, or a PCT application. Once filed with a receiving office, the International Searching Authority (ISA) conducts a search for related prior art. The ISA then issues a written opinion regarding the patentability of the invention. It is optionally followed by a preliminary examination, performed by the International Preliminary Examining Authority. Finally, the relevant national or regional authorities administer matters related to the examination of the application and the issuance of a patent.
