Obtaining a patent

Patent prosecution is the process of obtaining a patent through a national or regional patent office, addressing any objections raised by patent examiners and ensuring that the application meets the legal requirements for patentability.

It generally involves search and examination by the patent office.


During the search, the patent office considers the subject matter covered by the claims made in your patent application and determines what was already known in the public domain before the filing date of the application. Using this information the patent office then examines whether or not the application meets the legal requirements for patentability.


During examination the patent office will generally issue one or more examination reports, raising objections against the claims, i.e. indicating why they consider the application does not meet the legal requirements for patentability. An opportunity is then given for the applicant to submit arguments, and/or to submit amendments to the claims, so as to address the objections that have been raised.


Most patent offices require the applicant to have legal representation from a qualified local attorney, who can provide further advice on local patentability requirements and will prepare and submit responses to the examination reports following the instructions of the patent applicant.


Once the patent office is satisfied that the patent application meets the legal requirements they notify the applicant of allowance and grant a patent.


Appealing a refusal of a patent application

However, if despite the submitted arguments and/or claim amendments the patent office is not convinced that a patent application meets their legal requirements, they will refuse the application.


In this event, there is normally an opportunity to appeal this decision. For example, a decision by an Examining Division of the European Patent Office to refuse an application can be appealed and the decision will then be considered by a Board of Appeal.
