International Patent Filing Advantages

International patent filing is a highly competitive process. This is one of the most effective ways to protect your invention from counterfeiters or potential patent infringers located across multiple countries. You can file your application in more than one language, and the PCT system provides a system for submitting your application in multiple languages. When you enter the national phase, you must pay the filing fees for each country. Once you have filed an application in a single language, you can use the PCT system to submit your application in all languages, including the language you intend to use for the patent. 

International patent filing is a complex process, but it is worth it. The process is faster and more effective than ever. The Paris Convention patent filing enables you to file a single application in any one of 153 countries. The Paris Convention is a global agreement for the protection of industrial property, and most countries adhere to it. By filing your first application in a participating country, you will get provisional protection in those countries. Then, you will need to engage a local patent representative in the other countries you wish to file your patent application.
