The Examination is the process of ensuring that an application complies with the requirements of the relevant patent laws and basic criteria of patentability. This includes novelty, non-obviousness and industrial applicability requirement. The examination plays a very critical role to decide the fate of an invention. The examination system varies from country to country and completely depends upon local patent rules and regulation. We have tried to give an insight of difference in patent application examination process in major patent offices such as USPTO, EPO, JPO, KPO (South Korea) and IPO (India).
In USA, a patent application is examined by default (assuming that all of the required materials (i.e. specification and oath/declaration) have been filed. There is no need to file a request for examination, unlike certain other countries. An examiner is assigned to your application in the appropriate art unit. However, the applicant or attorney can file a status request with the United States Patent and Trademark Office when he or she thinks that the USPTO has forgotten about his application, or has misplaced his application.
If, you file a "Provisional" Utility US patent application it is not examined. You must file a "non-provisional" utility US patent application to have the claims examined or petition for conversion of provisional into a non-provisional. The filing fees include a filing fee, a search fee, and an examination fee. If only the filing fee is paid, the USPTO will not examine your application until the search and examination fees are paid.

At EPO, There is a need to file “request for examination” to examine whether the European patent application and the invention meet the requirements of the European Patent Convention and whether a patent can be granted. The request for examination may be filed from the date on which the application is filed up to the end of six months after the date on which the European Patent Bulletin mentions the publication of the European search report. If the request for examination is not filed within this period, the application is deemed to be withdrawn. When accelerated examination is required, the applicant files a request for examination before the search report is transmitted to him, he may also dispense with the need to comply with the invitation pursuant to Rule 70(2), and file a categorical request for examination whatever the result of the search may be, by which the procedure can also be accelerated (see Notice from the EPO dated 14 July 2007, Special edition No. 3, OJ EPO 2007, F.1). In this case, confirmation that he desires to proceed further with his application is deemed to be given when the search report is transmitted to him, so that in accordance with Rule 62(1) the search report is not accompanied by a search opinion.
AT JPO (Japan), request for examination is needed. For national phase application request must be filed within three years from the filing date (PCT). The accelerated examination is available in Japan and first office action usually issues within 6 months or less of filing the request for accelerated Examination. JPO also started trial of “Super Accelerated Examination,” to meet the needs of applicants who require quicker results
At KPO (South Korea), request for examination is needed. Request for examination is required within 5 years from the filing date. There is preferential examination in South Korea where, the commissioner of the Korean Intellectual Property Office may direct an examiner to examine an application in preference to another.
In India, Request for examination is needed, within a period of 48 months from the date of priority of the application or from the date of filing of the application whichever is earlier. Where no request for examination of the application for patent has been filed, the application will be treated as withdrawn.
