Should I consider filing for foreign patent protection?
Only if you have established business ties in foreign countries or another good reason to do so
Because foreign filing is expensive, I generally do not recommend that small businesses, startups, or solo inventors do so unless they have a viable plan to profit from it. Profiting in foreign markets in the future without current existing business relationships, distribution channels, etc., in foreign countries is possible, but not common, in my experience. It may take years to build necessary relationships that can be financially exploited for profit. By the time a startup would establish foreign relationships, it would begin incurring annuities59 to maintain the pendency of the patent application and would therefore divert funds away from operations in the United States, which makes financial success in the U.S. difficult.
How much does it cost to secure foreign patent protection?
Not much to preserve your right to do so, but a lot to secure foreign patents.
As discussed in Chapter 6, there is no initial cost to preserve the ability to file patent applications in foreign countries. An inventor only needs to file a patent application in the United States before engaging in marketing activities. An applicant must file utility patent applications in any foreign country within twelve months after filing a utility patent application, or after six months for design patent applications.
The twelve-month deadline to file utility patent applications in a foreign country may be extended another eighteen months by filing a Patent Cooperation Treaty (PCT) application. Read more about the pros and cons of worldwide patent protection. A PCT application gives an applicant up to thirty months from the initial filing of the patent application to file in foreign countries.60 The PCT application does not apply to design patent applications.
Instead of filing the PCT application, a patent application can be filed directly in foreign countries, but it can be quite expensive because of annuities. Many foreign, patent offices require an annuity (i.e., an annual payment) to the foreign patent office to maintain the pendency of the patent application. They range between a few hundred to a few thousand dollars each year. There are also annual maintenance fees to maintain issued patents in force.
If a business needs to seek foreign patent protection, the entrepreneur can file the PCT application and, within the thirty-month period, actively establish foreign business relationships or licensees that already have those foreign business relationships. The thirty-month period is crucial because, at the end of thirty months, the business will have to file patent applications directly in each individual foreign country, which may be cost-prohibitive without any assurance that the business will be profitable in those foreign countries.
