The one-year grace period allows inventors to apply for a patent within one year after publicly disclosing or marketing their invention.
The start of your marketing effort occurs when you first offer your product for sale, distribute a printed publication, or demonstrate how your product works in public. After the start of your marketing efforts, you have only one year to file a patent application. Otherwise, you cannot get a patent for your invention. Your invention has been dedicated to the public.
Should you wait one year to file your application?
Inventors are excited to learn about the one-year grace period. They can delay patent-related expenses until after they tested the market. However, we don’t recommend relying on the one-year grace period.
Here’s why.
Yes, you can start marketing your product without filing a patent application to test the market. When other people see your idea and decide to compete against you, they will create prior art. Their sales and product webpages can be used to reject your later-filed application. Remember you decided to file your patent application later after you’ve tested the market. All of the activities of other people before you’ve filed your patent application can and will be used to reject your application.
The worst part is that you have to tell the Patent Office about all your competitor’s activities. You have a duty of disclosure to tell the examiner about these activities in an information disclosure statement. Otherwise, you’ll be charged with inequitable conduct when you sue your competitors for patent infringement. Your patent will be invalidated and you may even be sanctioned.
What’s the purpose of the one-year grace period?
The purpose of the one-year grace period is to give inventors a second chance if they inadvertently failed to file a patent application on their invention before they started their marketing.
The purpose is not to give inventors time to test the market. At least, the patent law isn’t written to encourage that type of behavior.
Let me explain.
Oftentimes, inventors will market their products without a patent and start to make money. Now that the product is doing well, they want to get a patent on their invention. They are afraid that others will start to compete against them and take away their market share.
In these cases, they can take advantage of the one-year grace period and file a patent application. The one-year grace period gives these inventors a second chance.
However, if others have already started to compete against them, then these inventors may be prohibited from getting a patent. The marketing efforts of these other competitors become prior art. If they wanted to protect themselves against this situation, they should’ve file their application before going to market. For this reason, we recommend filing a patent application before you start your marketing efforts.
Do foreign countries have a one-year grace period?
Many foreign countries do not offer a one-year grace period. If they do have a grace period, its a variation of the true one year grace period. If you’re interested in international patent protection, I recommend that you file your U.S. patent application before beginning any marketing efforts. This approach preserves your right to seek patent protection in all foreign countries, regardless of their grace period rules.
This procedure keeps everything simple and you don’t have to litigate whether you filed the patent application within the grace period or not.
Countries with Grace Periods
- One-Year Grace Period: Australia, Brazil, Canada, Chile, Colombia, Estonia, Japan, South Korea, Malaysia, Mexico, Peru, Philippines, Turkey, United States, Singapore.
- Six-Month Grace Period: Albania, Eurasia, Japan, Russian Federation, San Marino.
Using the one-year grace period in the United States may jeopardize your ability to obtain patents in many countries that don’t offer this grace period.
Does Europe Offer a Grace Period?
Most European Union member countries do not have a grace period. This means that you must file your patent application before any public disclosure or marketing if you wish to obtain patent protection in Europe.
Does Taiwan Have a Grace Period?
Taiwan provides a 12-month grace period, but it only applies to disclosures made in non-patent publications. Marketing or other forms of public disclosure may not qualify, so it’s essential to understand the specifics when pursuing patent protection in Taiwan.
A Simplified Approach for International Protection
Because each country has different grace period policies, we recommend filing your patent application before any commercialization or marketing. This approach simplifies the process and ensures you can seek patent protection in any major economy, without concern for varying grace period rules.
