Patent Prosecution And​ Office Action Response

Patent prosecution generally refers to the process of advancing a patent application towards grant and securing patent rights. The patent prosecution process starts with the filing of a patent application and entails patent office action response 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 service involves understanding the objections raised by the patent office, preparing a strategy to overcome the objections, and issuing an office action response to the patent office in writing.  

Novelty, obviousness, and inventive step are common issues raised by the patent office. Patent prosecution specialists analyze the objections and documents cited by the patent office and prepare a written action 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 analyzing office actions received from patent offices and responding to office actions for advancing patent applications toward the grant.

Our Services

Office action response drafting

Response to OA/ER determines the direction of prosecution. Hence, it is important to carefully prepare the response. For preparing the response, we, at TTC, analyze the OA/ER and understand the viewpoint of the Examiner. Based on the cited documents, we prepare a strategy on whether to amend or provide arguments to overcome the objection/rejection. 

While amending, care is being taken not to make amendments that may result in unnecessary narrowing of the claims.

We also deal with complying with Formal requirements of different jurisdictions which may have arisen in OA/ER. We assist in preparing responses to Non-Final Office Action, Final Office Action, First Examination Report, European Search Opinions, International Search Opinions, etc. 

Devising multiple strategies for responding to objections

As the response to OA/ER decides the next course of patent prosecution, it is important to carefully reply to the objections/rejections raised in OA/ER. We assist clients in preparing multiple office action response strategies. 

This provides multiple alternatives for clients to take decisions based on current and future business and legal scenarios. The client may select the most suitable strategy to move forward. 

Drafting instruction letter to associates in various jurisdictions

Many clients file patent applications in different jurisdictions. They must respond to issued OA/ER individually for each jurisdiction to obtain a grant in that jurisdiction. 

We assist clients in drafting instruction letters to foreign associates for preparing responses to patent applications in relevant jurisdictions.

Detailed claim chart preparation

We assist clients in preparing a claim chart indicating a thorough mapping of claimed features of the invention and relevant features of the cited documents. 

This service helps clients clearly differentiate the features of the claimed invention and prepare the most suitable amendment and response strategy. 

Oppositions and third-party observations

We help prepare responses to pre-grant and post-grant oppositions. We also assist clients in determining the closest prior arts for issuing notice of opposition. 

We further provide our observations to clients, which help them decide a course of action in opposition proceedings. 

Appeal briefs and reply briefs

We also assist in preparing pre-appeal briefs, appeal briefs, and reply briefs, particularly in US jurisdictions.

No. Issuing an office action is a common practice and, in fact, one of the steps of patent prosecution process of a patent application. An office action is issued by any patent office to make sure that a patent is issued for 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 a response or to comply with the office requirements may result in the issuance of another office action or rejection of the patent application. 

Yes. An examiner can combine two or more documents while examining the 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 to the description or claims once the patent application is filed. In some jurisdictions, examiner may allow the incorporation of features described in the filed specification into the claims. 

Different jurisdictions have different provisions for speaking with the examiner. For instance, during prosecution in the US, it is possible to schedule a call with the examiner after the issue of an OA to understand his viewpoint. During prosecution in India, a hearing provides an opportunity to discuss the invention with the examiner.
