If so, you should consider the advantages that are offered by filing an " international" patent application under the PCT. By filing one international patent application, you can simultaneously seek protection for an invention in each of a large number of countries
If your answer is yes, you should consider that the "international search report" contains a list of documents relevant as to prior art which you can evaluate and which is sent to all of the countries in which your international patent application has effect.
You also have the option of obtaining an international preliminary examination report, which gives you even more information about the patentability of your invention before you incur the high costs of the patent granting procedure in each of those countries.
If so, you should take into account the benefits of international standards which are applied by the "international Searching Authorities" and the "International Preliminary Examining Authorities" when carrying out the international search and the international preliliminary examination of your application
Any patents subsequently granted on the international application by the national or regional Offices can be relied on by the applicant to a greater extent than would have been the case without the benefit of the international search report and the international preliminary examination report.
Your are entitled to file an international patent application if you are a national or resident of one of the PCT Contracting Steats
You can file your international patent application with your national Patent Office which will act as a PCT "receiving" Office or, unless not permitted by security provisions in your national law, with the International Bureau of WIPO.
If you are a national or resident of a country which is party to one of certain regional patent treaties (the ARIPO Harare Protocol, the Eurasian Patent Convention and the European Patent Convention), you may alternatively file your international patent application with the regional Patent Office concerned, if permitted by your national law.
Your international patent application has the effect of a national patent application in those PCT Contracting States which you "designate" in your application. It has the effect of a regional patent application in those among the PCT Contracting States which are also party to a regional patent treaty (the ARIPO Harare Protocol, the Eurasian Patent Convention and the European Patent Convention and OAPI Agreement), provided they are designated for a regional patent( It should be noted that, for some of these States, only a regional patent patent can be obtained via the PCT)
Because your international patent application must be prepared in accordance with international standards effective in all of the PCT Contracting States, subsequent adaptation to varying national( or regional) formal requirements ( and the cost associated therewith) will not be necessary. The granting of a patent remains the responsibility of the national or regional Offices but the start of the processing of your application before those Offices (the "national phase" or "regional phase") including examination as to substance, is delayed until after the end of the 20th or 30th month from the priority date.
Because your international patent application is effective in all designated PCT Contracting States, you do not have to incur the costs that yould arise if you prepared and filed separate applications for all of those States, and you have to pay only a single set of fees for filing your international patent application with the PCT receiving Office.
Information about these fees can be obtained from the receiving Offices. They cover the filing, searching and publication of your international patent application, and are payable in the currency or one of the currencies accepted by your Office (receiving Office).
National fees in the designated States become payable much later because national processing is delayed if you use the PCT. In several Offices, including the EPC, national fees are also lower for international patent applications than they would be if you filed separate national applications.
The language in which your international patent application under the PCT can be filed depends upon the requirements of the receiving Office with which it is filed. Depending on the rules applicable in your PCT receiving Office, international patent applications may be filed in Chinese, Danish, Dutch, English, Finnish, French, German, Japanese, Norwegian, Russian, Spanish, or Swedish.
In your international patent application, you may claim the priority, under the Paris Convention, of your earlier patent application for the same invention, whether it was a national, a regional or an international(PCT) application, for up tp 12 months after the filing of that earlier application. If you do not claim priority from an earlier application, the priority date will be the international filing date of your international application.
Every international patent application is subjected to an "international search" by an International Searching Authority(ISA). International Search is a high quality search of the patent documents and other technical literature at least in those languages in which most patent applications are filed ( Chinese, English, French, Germany, Japanese, Russian and Spanish).
The high quality of the search is assured by the international standards prescribed in the PCT for the documentation to be consulted, and qualified staff and effective search methods of the ISAs, which are experienced Patent Offices that have been specially appointed to carry out international searches.
The following are the ISAs: the national Offices of Australia, Austria, China, Japan, the Russian Federation, Spain, Sweden and the United States of America, and the European Patent Office. For a given international patent application, there will be one or more competent ISAs.
The results of the international search are set out in an "international search report" which is made available to you by the fourth or fifth month ( or tenth month, if no priority is claimed) after the international patent application is filed.
The international search report contains no comments on the value of your invention but lists citations of prior art relevant to the claims of your international patent application and gives an indication of the possible relevance of the citations to the questions of novelty and inventive step( non-obviousness).
This enable you to evaluate your chances of obtaining patents in the countries you have designated. A search report which is favorable, this is, in which the citations of prior art would appear not to prevent the grant of a patent, assists you in the later prosecution of your application in those countries in which you wish to have protection.
If a search report is unfavorable, you have the opportunity to amend the claims in your international patent application or to withdraw the application before it is published. The high quality of the international search assures you that any patent granted is less likely to be successfully challenged, and thus provides valuable input to investment decisions
Under the PCT system, you have the option, as applicant, to have an international preliminary examination of your application carried out, on payment of a fee, for the purposes of the patent granting procedure in any of those PCT Contracting States which recognize the international preliminary examination procedure.
This preliminary examination is made on the basis of the international search report according to internationally accepted criteria of patentability ( novelty, inventive step and industrial applicability). It is carried out by an International Preliminary Examining Authority (IPEA) having qualifications similar to those of the ISA mentioned above.
As applicant, you participate actively in the international preliminary examination. The IPEAs are the ISAs mentioned above except the national Office of Spain. For a given international patent application, there will be one or more competent IPEAs.
The results of the international preliminary examination are set out in an "international preliminary examination report" which is provided to you. The report consists of an opinion on the compliance with the international criteria mentioned above of each of the claims which has been searched.
It provides you with an even stronger basis on which to evaluate your chances of obtaining patents, and, if the report is favorable, a stronger basis on which to deal with the national and regional Patent Offices when prosecuting your application before them.
It should be noted that the decision on the granting of a patent remains the task of each of the national or regional Offices designated in the international patent application; the international preliminary examination report is authoritative but is not binding on those Offices.
Until international publication ( 18 months after the priority date), no third person is allowed access to your international patent application unless so requested or authorized by you. If you wish to withdraw your application ( and you do so in time before international publication), international publication does not take place.
When an international patent application has been filed, all national procedures in the designated States are delayed until the end of the 20th month from the priority date or, if international preliminary examination is requested before the end of the 19th month from the priority date, until the end of the 30th month from that date.
The delay gives you at least eight months ( or 18 months where preliminary examination has been sought) more, before you have to fulfil the national requirements, than if you do not use the PCT. This additional time can be very useful for evaluating your chances of getting patents and of exploiting your invention commercially in the various designated countries, and for assessing the technical value of your invention as well as the continued need for protection in those countries. In making your evaluation, you have the benefit of the international search report and possibly the international preliminary examination report.
It is only after you have decided whether, and in which States, you wish to proceed further with your application that you must fulfil the various national requirements for entry into the national phase. These requirements include paying national fees and, in some cases, filing translations of the application as filed and/or as amended. These steps must be taken before the end of the 20th or 30th month from the priority date. There may also be other requirements in connection with the national phase, for example, the appointment of local agents. Have you decided to enter into Korean national phase ? If so, contact us
The substantive examination and other processing of your international patent application before the national and regional Offices is made easier by the international search , which enables you to make necessary amendments to your application even before the national or regional procedure starts. It is facilitated even more by international preliminary examination during which further amendments are possible.
You also achieve other savings in communications, postage and translations from the work done during the international processing and not repeated before each designated Office ( for example, you must submit only one copy of the priority document instead of having to submit several copies).
