Cost of a Worldwide Patent

The cost of a worldwide patent on an invention can cost millions. Getting a patent in almost all of the 200 countries could potentially cost about $1,000,000 for issuance and filing. In addition, it could cost another $1,000,000 to uphold the patent for its entire term.

The best way to manage your expenses is by using a Patent Cooperation Treaty (PCT) application. It makes it possible for you to file just one patent application internationally. Just that one application is accepted by up to 150 countries around the world. Also, a PCT application lets you postpone for up to 2-1/2 years in making a decision about which countries in which you should file. After you have filed your PCT application, it is translated into individual patent applications for each country where you are seeking patent protection. If you have a completed patent application, filing a PCT application could cost roughly $4,000.


The first place to start when considering worldwide patents is by applying for a domestic patent.

A patent gives the holder an exclusive right to an invention for a set period of time. After filing for a U.S. patent, there is a limited window of time in which to apply for international patent protection.

While a start-up may only be operating in the U.S. for now, with success it may want to expand abroad. If that is a possibility, then the company needs to act immediately to capitalize on international patent protection. Once the allotted time to apply for international patent protection expires, that company could be prevented from getting a patent for its own invention.

Strategy for Patent Application

Filing only where there are products being made that would be considered competitive with yours is a good strategy to keep expenses down.

For example, if products that compete with yours are made in China only but sold worldwide, just one patent in China would protect you around the world. But defending a patent in contradiction of sellers in the U.S. is easier than defending one in China, so having a U.S. patent, too, is prudent. You can apply this concept to as many countries as you can afford.

International Patents Enforcement

Applying for an international patent is easy using the PCT, enforcing them is still complicated, and of course, expensive.

The realities of enforcement should be considered when it comes to cost management and considering whether or not undertaking patent costs in a particular country is acceptable. The U.S. is the easiest country to take action. China remains difficult but enforcement is much easier now than it was in the past.

Enforcing a patent in Brazil, Russia, India, and South Africa is still quite difficult. These are countries where you might reconsider shelling out all the money it requires to obtain a patent. Your money might be better spent elsewhere.

Background on Patents

A patent has numerous important elements, including a disclosure that discusses the invention in detail and includes drawings, lists of prior art, and claims, which discuss what the patent protects.

The only way you truly know if a patent is valid is to have it tested in a lawsuit and in a subsequent appeal. If your patent survives the litigation process then you really know that it's valid.

How to Obtain Worldwide Patent Protection

How do you get worldwide protection for your invention? If you're an American, it all starts in the US.

The key date is the U.S. filing date for your patent application.

Once you file the U.S. patent application, there is up to a year, under international treaties, to seek international protection which is under two key treaties.

One is the Paris Convention, which is over 100 years old. You can file in the U.S. and within one year, file in most other countries of the world in their patent offices and claim the benefit of the priority of the U.S. filing date.

The other treaty that is very important for you is the Patent Cooperation Treaty, or PCT, described above. A PCT application buys you an additional 18 months, or 2-1/2 years, from the date that you filed the U.S. patent application until you actually have to go into any other country or jurisdiction.

There are five leading jurisdictions in the world for patents.

One is the U.S. Patent and Trademark Office, or USPTO, one is the European Patent Office, or EPO. Another is the Japan Patent Office.

The fourth and fifth jurisdictions are China and Korea, which are very important jurisdictions for patents. Between the five jurisdictions, China and Korea is where the 90 percent of the patent applications in the world are filed.

Obtaining Patent Rights Around the World

Patents are granted by each country individually, not by any comprehensive international think tank.

A single international patent-granting process is impossible because different countries have different patent laws. However, the European Union will soon be granting a Europe-wide patent. Even then, obtaining a patent around the world will require consultation with more than one jurisdiction, all of whom will need to approve the application and grant the patent.

The patent protection you receive varies from country to country varies based on whether the country issuing the patent has an efficient enforcement program in place. It also varies depending upon whether or not a certain country will even grant a patent on the proposed invention.

When you are seeking international patents, it is smart to draft an application so that it would be appropriate in the U.S. and China, since the U.S. and China construe their applications using some of the most strict disclosure requirements.

Coordination of international prosecution can be taken care of by your patent attorney, but they cannot represent you in countries that do not allow them to practice. It is required that you have separate representation in all countries that you want to get a patent.

Where Should I Pursue Patent Rights?

It is very important to file a patent application as early as possible. If you would like a patent, you need to file an application before disclosing or using the invention.

India may also seem to be of interest for international patent application given the size of the market

Maintaining and Estimating Patents Around the Globe

Living in the competitive world we have today, companies must constantly be more and more innovative in order to keep that competitive edge, while handling budgets that are shrinking for R&D and staying abreast of the constantly changing expenses related to getting international patent protection.

Estimating expenses can be time-consuming and challenging. Expenses usually have three different segments – an official segment, an associate or attorney segment, and a translation segment - which are disseminated across the various stages of the patent application process.

The entire estimated expenses to maintain and file an application or approved patent through to expiration range from $25,668 in Japan to $11,404 in Israel.

Costs for translations is tremendously high and range from $6,444 in Japan to $1,565 in Iran.

The estimated costs to request inspection in additional jurisdictions differ from $2,254 in Europe to $496 in India and are comprehensive of the expenses for additional claims in South Korea and Japan and the expenses for extra independent claims in Russia.

If it’s assumed the PCT application is fairly straightforward, the prosecution vary from $5,068 in Japan to $533 in Iran.

The projected expenses to be paid when time of patent grant/ allowance /issuance vary from $3,596 in EP to $143 in China.

Cost-Saving Strategies

Other countries make it very difficult to patent business methods or software. For these jurisdictions, you may need to draft your claims specifically to overcome these obstacles.

Also, some countries charge additional fees for each claim included in an application above a certain number. If you can manage to limit the number of claims that you have, you can prevent incurring these types of fees.

Depending on how much patent work you have, it could be less expensive to hire an in-house patent attorney, rather than retain outside counsel. Outsourcing other services in your patent portfolio can be an easy way to trim your legal fees.

Many steps of the foreign filing process are primarily administrative. A company can easily outsource those jobs to reduce their patent expenses.

Defining Your Idea and Understanding Patents

Patents can only be applied for in the name of the actual inventor(s).

You can apply for a patent individually or as part of a joint research group.

There are three key kinds of patents: plant, design, and utility. These have been established for various kinds of inventions.

You can protect a utility patent for a machine, process, article of manufacture, an improvement upon any of these existing products, or composition of matter (i.e. a drug).

You may apply for a different kind of patent, but you may also patent an ornamental design of an asexually reproduced plant variety or an article of manufacture.

Your creation must offer some usefulness to society, must not be unpleasant to public values of morality, and must be original, adequately described or enabled, non-obvious, and claimed by the inventor in clear and certain terms.

There are numerous products or ideas of human work that is not able to be patented; however, several can be protected through additional channels such as a copyright.

You are not able to patent the following: physical phenomena, laws of nature, abstract ideas, and musical, dramatic, literary, and artistic works (you must have a copyright for the above).

A utility patent should be applied for a product that has a precise value to society.

A utility patent protects a product for 20 years from the day the patent is approved.

Apply for a design patent when you have an invention pertaining to a new and improved design on an already standing process or product which does not disturb the functionality of the novel product.

A design patent lasts 14 years from the date of the original patent application.

A plant patent is appropriate if you create a novel asexually-reproductive type of plant. A patent on a plant is protected for 20 years from the initial patent application date.
