Filing a Patent Cooperation Treaty (PCT) application is the most common method of filing internationally. Certainly, we can help you file in specific countries, but would need to reach out to co-counsel in said countries. These applications do not change in substance or content so much, but the examiner doing the searching and examination is what is called an International Search Authority (ISA) and that search and examination will be relied upon by the various countries that have signed up to the PCT (90+ countries).
We work with you and your business to help you understand the value that having international rights can be. From having already worked on your underlying U.S. Patent Application, we will be best suited to represent you before the world. Specifically, we also will help you interpret and forecast the costs involved in fully filing and enforcing your rights overseas so you can make the best decision possible.

Once you understand the PCT Application Process, you can apply for patent protection in multiple countries. In fact, you can file for a patent in as many as 155 countries using just one application!
Ultimately, the national patent office — or the European Patent Office for EU countries — examines and decides whether to grant the patent. The process includes several steps:
It is worth noting that you have up to 30 months from the date you filed the initial patent application — or up to 18 months after filing a PCT application — to decide in which countries you would like to enter the national phase for patent protection. This gives you time to explore your options.
