What is an invention?
An invention is a new, inventive and useful solution to a problem.
It can be a novel device, process or product.
Inventions that meet the criteria for patentability can be protected through patents.
What is a patent?
A patent is a form of intellectual property granted by a government that confirms the exclusive right to an invention for a period of up to 20 years.
A patent is only valid in the country where it is granted.
You cannot obtain an international patent.

Virtual reality glasses
Distillery process and method for bottling liquid
Compositions of matter
What cannot be patented?
Higher life forms
Animal, plant or cellular organism
Mathematical models and formulas
Idea in someone's mind
Improving existing inventions
An invention does not have to be an entirely new device, process or product.
It can be—and is most likely to be—an improvement to an existing invention.
About 90% of patents are for improvements to existing patented inventions.
Headphones have existed for a century but continue to evolve with technology.
The criteria for patentable inventions are found in the Patent Act, which is the federal legislation governing patent law in Canada.
How do you know if you have an invention eligible for a patent?
Your invention must be new, useful and non-obvious.
Your invention must be the first of its kind in the world.
It must not be known to the general public in writing or in any other form anywhere in the world before the application is filed.
Your invention must work at a practical level and have a useful function.It simply has to have a use.
Your invention must be something that a person with relevant technical experience and knowledge would not have thought of.
How to obtain a patent?
Start by submitting a patent application to the Canadian Intellectual Property Office (CIPO) to secure a filing date.
In Canada, patents are granted to the first person to file an application.
A patent gives you the exclusive right to prevent others from making, using or selling your invention in any manner.
This only applies to countries that have granted you a patent.
It is valid for up to 20 years from the date you file your application.
Value added by patents
Holding a patent can boost investor and stakeholder confidence.
It makes it easier for small and medium-sized businesses to attract financing from investors in order to take their business to the next level.
Patents can also give you a competitive edge and ensure market exclusivity by acting as a barrier for your competitors.
Remember: The patent holder is the sole person with the exclusive right to use, sell and manufacture the innovative technology for up to 20 years.
Patents can also be a revenue source.
You can use your patented technology for the purpose of:
You can use, manufacture or sell your invention directly to consumers in the marketplace.
You can allow another party to exploit your patent for monthly royalties.
You can sell or transfer your patent ownership to another party for an immediate lump sum of money.

Using patents strategically
Commercialize your invention
Turn your patent into dollars!
Getting legal rights to your invention through a patent gives you proof of ownership. This is crucial to gaining the most commercial value.
Turn your know-how into a commercial asset!
Holding a patent may open up opportunities for business growth and job creation.
Consider a licensing agreement. For start-up businesses, licensing is typically the fastest way to generate cash flow.
What are some of the benefits of licensing your patent?
- Leverage existing manufacturing deals and distribution channels
- Access existing markets and benefit from established names
- Reinvest in further research and development
- Use revenues earned from monetizing your patent to finance further research and development for your company
Export your invention
You must obtain a separate patent for each country where you seek protection.
Consider strategically filing for patent rights in countries where you plan on doing business—to sell or manufacture products, license your technology or assign your IP to another party.
For more information on seeking patent protection internationally, consult the World Intellectual Property Organization (WIPO) web page on the Patent Cooperation Treaty.

Applying for a patent in Canada
Be the first to file
Patents are granted to the first person to file an application.
File as soon as possible in case someone else is on a similar track.
Keep secrecy before applying
Keeping secrecy before filing is crucial to prevent others from filing for the same invention before you.
Consider confidentiality and non-disclosure agreements if you must reveal your invention to anyone before you file your patent application.
If you publicly disclose your invention before filing, it may be impossible to obtain a patent because the invention will no longer be considered new.
However, you could benefit from Canada's 12-month grace period, which allows applicants to file after disclosing the invention.
Search patent databases
Before you file, search for existing patents or patent applications. This will determine if your invention, or a similar one, has been patented already.
Start with the Canadian Patents Database on the CIPO website.
Search using key words, the name of the inventor, the owner or the applicant, or any other relevant terms. You should also search international databases to see what has been patented across the world.
- Google Patents
- United States Patent and Trademark Office website
- European Patent Office website
- WIPO PATENTSCOPE database
Understand the application process
Make sure you understand the patent application process at CIPO.
Consult the roadmap for a visual representation.
Submit your application
Use our electronic services to file your application and pay fees online, or mail your application and payment to CIPO.
CIPO will only accept applications in English or French.
To receive an official filing date in Canada, you must include in your application:
- a statement that a patent is sought
- a document describing your invention
- your name and address
- the filing fee and, if applicable, a signed small entity declaration
Note: An entity is considered small if it employs 50 or fewer employees or is a university.
While you can get a filing date without sending in a complete application, you should make your first application as complete and descriptive as possible.
CIPO must receive your complete application within 15 months of the filing date.
See the complete list of elements that you need to include in your application.
Publication of your patent application
Your complete application will be published in the Canadian Patents Database generally 18 months after filing.
Patent applications are not automatically examined simply because they have been filed.
You must request that your patent application be examined within five years of the Canadian filing date and pay the examination fee. Otherwise, your application will be considered abandoned.
The examination process could take up to a few years to complete because CIPO receives a large number of patent applications.
For more information on response times, take a look at CIPO's service standards.
You can pay an advanced examination fee ($500) in addition to the request for examination fee to accelerate the examination of your patent application.
There are other ways to fast-track the examination of your application. Follow these links for more information.
- Patent Prosecution Highway (PPH)—Fast-track examination
- Patent applications relating to clean technology inventions
What happens during examination
A patent examiner will review your application and decide whether your invention is new, useful and non-obvious, as per patent legislation.
If your application is not acceptable, the examiner will explain why, and you will then have a chance to make changes to it.
Obtain your patent
If everything is in order, you will receive a Notice of Allowance by mail, and you will then have six months to pay your final fee.
CIPO will mail the patent grant to you within eight weeks of receiving the final fee.
For financial planning purposes, see the list of standard fees for patents.

Managing your patent
Pay annual maintenance fees
Keep your patent application or granted patent in good standing by paying annual maintenance fees.
The first payment is due no later than the second anniversary of the filing date.
Monitor patent infringement
It is your responsibility to monitor the marketplace for any unauthorized use of your patented item.
If someone is infringing on your rights, take action.
Consider seeking the help of an IP professional, as litigation matters can become complex.
Consider alternative dispute resolution methods such as arbitration, mediation and negotiation to solve IP litigation situations.
How to detect patent infringement
Here are some tips for detecting patent infringement:
- Monitor your competitors. Look at their products and check for copycats.
- Attend trade shows and look for new products on display that will be marketed.
- Do online research related to your technological field, read journal articles and look for companies looking to tap into your field.
- Set online alerts to stay informed of new developments and key words that are of interest to you.
Revise your patent portfolio
Consider the following tips to effectively manage and increase the value of your patent portfolio:
- Regularly evaluate your individual patents and align each one with your current business goals. Identify those that fall outside of these goals.
- Consider selling under-utilized or unused patents to free resources, as maintaining such rights can get expensive.
- Consult with technology or industry experts before selling any of your patents or letting them expire.
By eliminating inefficiency, you are focusing on generating solid new business growth.
