Patent Prosecution &​ Office Action Responses

Patent prosecution generally refers to the process of advancing a patent application towards grant and securing patent rights. Patent prosecution starts with filing of a patent application and entails responding to communications received from Patent Offices. 

In case the Patent Office has objections to the grant of the patent application, the Patent Office communicates the objections to the applicants and/or representatives of the applicants.

Patent prosecution involves understanding the objections raised by the Patent Office, preparing a strategy to overcome the objections, and responding to the Patent Office in writing. 

Novelty, Obviousness, and Inventive Step are common issues raised by the Patent Office. Patent prosecution professionals analyse the objections and documents cited by the Patent Office and prepare a written response comprising amendments to claims and/or arguments to assert the patentability of the patent application. 

We, at TT Consultants, have qualified & experienced Patent Agents & Technical engineers with technical & legal knowledge to assist our clients in analysing Office Actions received from Patent Offices and responding to the Office Actions for advancing patent applications towards grant.

No. Issuing an Office Action is a common practice, and in fact, one of the steps of prosecution of a patent application. An Office Action is issued by any patent office to make sure that a patent is issued to a valid invention.​

There is no specific format to prepare the response. However, it is essential to respond to all the objections raised in the Office Action. Leaving or refusing to provide response or to comply to the office requirements may result in issuance of another office action or in refusal of the patent application.

Yes. An Examiner can combine two or more documents during examining non-obviousness/inventiveness requirement if they think that a skilled person would be able to do so. The Examiner provides reasoning as to why the different documents can be combined. ​

Any new matter cannot be added in the description or claims once the patent application is filed. In some jurisdiction, Examiner may allow incorporation of features that have been described in the filed specification into the claims. ​
