Can I write the complete specification in non technical style?
The Complete Specification is a technical as well as a legal document that fully and particularly describes the invention and discloses the best method of performing the invention.
As the Complete Specification is an extremely important document in the patent proceedings it is advised that it should be drafted with utmost care without any ambiguity.
The disclosure of the invention in a complete specification must be such that a person skilled in the art should be able to perform the invention.
Request for Examination
The applicant has to expressly demand for the examination of his application by filing up and submitting the required forms and making the corresponding payment for it.
A request for examination has to be made within forty- eight months from the date of priority of the application or from the date of filing of the application, whichever is earlier.
The Patent Office shall wait up to the end of thirty one months from the earliest priority date and then process the application.
However, the applicant may demand an expedited prosecution of the application at any time before the end of thirty one months period.
Examination report
The patent examiners shall search for similar earlier inventions in the same field as your patent application. Such similar earlier inventions are known as “prior art”.
Next, they will examine and compare the prior art to your patent application and determine if the prior art anticipates the novelty of your patent application. The patent examiner will also determine if the other patentability criteria (such as inventive step and industrial application) are met.
An examination report (FER) is prepared after conducting a prior art search to ascertain the novelty, and examining as to whether the invention disclosed in the specification is inventive and industrially applicable.
The Examiner also examines whether the invention belongs to one of the categories of non-patentable inventions coming under Section 3 and 4, and whether the application is in conformity with all the provisions of the Act.
The applicant is required to comply with all the requirements imposed upon him by the Act as communicated through FER.
Responding to the examination report
Applicant must respond to First Examination Report (FER) within SIX months, and the application must be put in order for a grant within TWELVE months of the FER.
If applicant fails to respond to the FER within six months from the date of issuance of FER or within an extended period of 3 months, the application is deemed to have been abandoned under Section 21(1) of the Act.
A communication to that effect is sent to the applicant for record.
If the response filed by the applicant does not overcome the objections of the examination report then the Controller shall offer an opportunity of a hearing to the applicant and decide the case on merits.
Subsequent to this hearing the Controller may either refuse the application or Grant the patent on the merits of the case.
What is a disclosure of the status under Section 8(1) of The Patents Act, 1970?
During prosecution, the applicant needs to inform the Indian Patent Office regularly about the status of patent applications corresponding to the same invention filed in other countries/jurisdictions.
Applicants must provide details of corresponding applications within six months of filing in India and failure to do so can result in the application being refused or lead to invalidation/revocation of any granted patent as set out in Section 8(1) of The Patents Act, 1970.
When biological material is described in the specification and when such material is not available to the public and cannot be described as per the provisions of the Act, such material shall be deposited to make the application complete.
