A patent is the government grant of the right to prevent others from making, using, and selling an invention for a specified time (20 years from filing). Patents are examined based on a number
of criteria. Domestic patents are granted by the U.S. Patent and Trademark Office, called the USPTO, and must be new, useful and non-obvious. Foreign patent offices, typically within each country,
grant patents based on similar criteria as that of the U.S., being new, useful, and have inventive step. Domestic, foreign, and international patent application processes are complicated legally and
procedurally, so it is wise to consult with an experienced patent attorney as early as possible in the evolution of the invention in question.
A patent application may initially be filed in one of three ways:
1) directly here in the U.S. as a domestic U.S. patent application;
2) directly within a foreign country as a foreign patent application; or
3) at a qualified international receiving office as an International patent application.
The Patent Cooperation Treaty (PCT) gives an inventor the ability to file an international patent application and reserve coverage in almost 150 different countries simultaneously.
The PCT is an international procedure established by an international agreement to which the U.S. is a signatory. The PCT is administered by a United Nations agency, the World Intellectual
Property Organization (WIPO), which is headquartered in Geneva, Switzerland.
WIPO has established an intricate, well organized system for the filing and administration of international patent applications. In the U.S., PCT applications can be filed with the USPTO, a PCT
An international patent application has a number of benefits. First, it acts to grant an inventor additional time (around 30 months) to decide which particular countries to enter. The extra time is
useful where the product is in an initial stages of development and marketing and further time is needed to establish the key market areas.
Secondly, the international application will be given an examination (international search report and written opinion) that can be used to further define and amend the application prior to entering
individual countries. These international findings help the applicant to evaluate the strength of the patent application and are used to make necessary amendments. All international searches and
reports are available to each of the national patent offices designated by the applicant for help later when deciding whether to grant the invention a national patent.
Third, cost savings may be realized if more than 3 or 4 national stage applications (direct filing in a particular country) will be filed. Although the initial filing fees for the international
application are higher than the U.S., consolidated examination and amendments within the PCT often lead to cost savings when entering each foreign country via a national stage application.
It is important to determine early on in the patenting process whether you as a business or entrepreneur desires to expand patent protection to the international markets. The globalization of markets
and intricate networking of economies necessitate its consideration. Patents are geographical in nature and each inventor should consider applying for a patent here in the U.S. and also in foreign
