Obtaining foreign patents requires filing patent applications corresponding to United States applications in the foreign countries of interest. A foreign application should be filed before a United States patent issues on the corresponding United States application; preferably within one year of the United States filing date (in order to receive the priority benefit of the United States filing date).
Fees and Costs: Corresponding foreign patent application in non-English countries may require translation. The cost of translation is a function of the length of the application, the language involved and the strength or weakness of the U.S. dollar against the currency of the country involved.
As indicated earlier, a PCT filing within one year of the United States filing date would enable your company to delay filing in individual countries, while still preserving the important United States filing date as explained on how to patent a product with InventHelp post.
The Patent Cooperation Treaty (PCT) is a process meant to offer you an affordable way to expand your patent protection across more than 130 countries, although there does not exist a worldwide patent.
Within 12 months of filing your priority for a patent in your home country, in order to get the international protection, you have to file under the PCT process. You then enter the “international phase” and this gives you two years time to formulate your strategy for national filing and, meanwhile, your patent is being protected. After filing for long-term protection in individual countries, you enter into the “national phase”. It is advisable to hire professional patent services, such as InventHelp patent services, to help you out.
Maintenance Fees are required to maintain foreign patents in most countries. In many countries, these fees are payable annually (which is why they are often referred to as “annuities”). The amount of foreign patent maintenance fees varies from country to country, and typically increase from year to year: foreign maintenance fees range from hundreds of dollars to the low thousands for each patent.
