If you are an inventor and willing to protect your invention then the next right step towards protecting your inventions is to file for a patent, that way you restrict others from making, selling or using your invention.  Before you file or submit a patent application in a particular country, it is better to perform patent search to get clarity about the patentability of the invention. Once the search is done, the next step is to draft the application according to respective country’s patent standards of the patent office of that country. Once you are ready with your draft, then you can go ahead and file the patent application.

In brief, patent filing is a process of submitting application to patent office of a country in order to get the grant for the invention in that particular country. If a person wishes to protect his invention in multiple countries, then he will have to file patent application in each of those countries separately.

There are multiple filings under which one may protect his/her invention. In order to identify the type of filing that suits your requirements, it is important to know all types of patent filings. Each type of filing serves a different purpose.

The types of Patent filing can be classified into:

It is necessary that provisional application is followed by complete patent application within prescribed time window, the complete patent application needs to be filed within 12 months from the priority date. In case if the complete application is not filed within prescribed time then the provisional application lapses. There are other advantages of filing a provisional application as well.
