Small Entity Reduction
A small entity is defined in Canadian patent law as a business with fewer than 50 employees or any university. Small entities pay only 50 percent of the standard patent application fees. In order to qualify for the fee reduction, the small entity cannot have licensed or transferred rights to the invention to a business with more than 50 employees – unless it is to a university. In order to file a patent application as a small entity, the entity must submit a small entity declaration stating they "believe they are entitled to pay fees at the small entity level."
Standard Patent Fees
As of 2011, the standard patent application fee is $400 Canadian dollars. Additional fees will need to be paid if the inventor requests an examination of the patent. The fee for this is CA$800. Applicants who have previously filed patent applications can request priority status. The fee for this is CA$500. If an invention was created by two or more inventors, but one of them refuses to file for a patent or cannot be located, the applicant can apply to have the patent granted in her name only. The standard fee for this is CA$300, if the application was filed after October 1, 1989. The fee for reinstatement of an abandoned application or restoration of a forfeited application is CA$200.
