The Patent Office may issue communications regarding their observations
on the patentability setting forth appropriate ‘Response’ and / or ‘Amendments’ from
the applicants to the original application. Usually, in about, one or two hearings
or responses, outstanding issues with regards to claims and the scope of protection
are resolved to the satisfaction of the Patent Examiner.
Patent application prosecution, however, is dependent upon many factors
such as the complexity of the subject matter, related prior art, quality
of the patent draft and finally the quality of compliance to objections
raised by the Patent Office.. After successful prosecution and upon
payment of required issuance fee etc., the patent is granted to the applicant.
