IS IT NECESSARY TO FILE A PROVISIONAL APPLICATION? |
|
Generally, an application filed with provisional specification is known as provisional application which is useful in establishing a priority date for your invention.

However, it is not necessary to file an application with provisional specification and one can file application directly with complete specification. |

WHAT ARE THE VARIOUS STAGES INVOLVED IN THE GRANT OF PATENT? |
|
After filing the application for the grant of patent, a request for examination is required to be made by the applicant or by third party and thereafter it is taken up for examination by the Patent office. Usually, the First Examination Report is issued and the applicant is given an opportunity to correct the deficiencies in order to meet the objections raised in the said report. The applicant must comply with the requirements within the prescribed time otherwise his application would be treated as deemed to have been abandoned. When all the requirements are met, the patent is granted and notified in the Patent office Journal. However before the grant of patent and after the publication of application, any person can make a representation for pre-grant opposition. |
