Imagine you have developed a groundbreaking product that is going to revolutionize your industry. You do not want your competitors to copy the product. At the very least, you want them to pay you compensation for making a competing product.
You know that if you want to protect the product, you should file a patent application. So, you hire a patent lawyer and file a U.S. patent application. Problem solved, right? Time to start manufacturing and marketing your product.

You will want to analyze each of the reasons to foreign file. You should consider whether it makes business sense to file in several countries, in a more tailored list of countries or in a particular country. We will describe the different considerations when preparing a foreign filing program and conclude with examples of how foreign patent protection may be pursued for two different products: a communications chip and a cell phone.
