The topic discusses patent law. Patent protection is different from copyright protection. Copyright protects a form of expression such as musical dramatic, literary or artistic expressions. Copyright also includes computer programs.
Patents protect an invention. The invention may be a product, apparatus, composition of matter or a process with a function or purpose. In some countries like Canada it is also possible to patent software or methods of conducting business, depending on the specific nature of the invention. The intention must be useful. It must be recognized as subject matter that may be patented according to the laws. For example, it must be novel. It must be new and not known to the public or the entire world. It must be non- obvious. It must have the requirements of inventiveness and not merely skilled improvements on the process. There are some things that cannot be patented. For example, you cannot patent professional skills, plants and higher forms of life, mathematical equations and anything that cannot be described with precision. Ideas cannot be patented but the physical embodiments of the idea can be.
Patented give inventors exclusive rights to their intentions. No one can make, use or sell the invention in the country where the invention is patented. No manufacturer may export or import, use or sell your patented invention, unless they procure a license to do so from you.
The Patent Office will not stop others from practicing your invention. A patent permits the owner of the patent to protect their own rights. The inventor must own the intention to patent it. The invention may be sold to second party before, during and after the process of obtaining a patent. The patent owner can sue a person who infringes the patent by using, making or selling an identical or similar thing. Once granted, a patent is good for 20 years after the application is filed. For Canadian patents, there are annual maintenance fees that must be paid. Inventions made by you as an employee of a company maybe that company’s property and their right to patent.
Before you apply for your patent, do a search with respect to your patent. The search will tell you whether someone else has already patented or disclosed something like or close to your invention. If you know what related inventions are patented, it helps you decide the scope of what you may claim as your own and avoids an infringement on others’ patents.
The form of the application is described in the Canadian Patent Act and in the rules set out by the Patent Office. The office regularly rejects applications that are not correctly done. Your application must include a petition, a detailed description of your invention, an abstract, at least one claim, any drawing referred to in the description and the filing fee. The claims define the scope of protection you are seeking for your invention. The claims define the scope of protection you are seeking for your invention. It must be clear what you are preventing others from on making, using or selling.
More detailed information about the Canadian Patent system and its requirements can be found at the Canadian Intellectual Property Office (CIPO) website:https://www.cipo.ic.qc.ca . This site also provides access to the Canadian Patent Database from which a patent search can be conducted. A list of registered patent agents is available from the Patent Office website.
Patents are made public 18 months after the application is filed. The publication is to share the knowledge with the public, so that society can benefit from this advance in technology and knowledge.
You must apply in each country where you want the patent protection. Canada’s patent laws do not protect your patent in other countries, It is not necessary to make an application in all countries at the same time to protect your rights. Accordingly to international convention, if you file in one country, you can file in most other countries within one year and have your position protected.
You should consult with a patent agent regarding protecting your invention in other countries, as there are variations to the laws that apply to the patents. Generally, inventions must be new and should not have been made available to the public before you file your application. However, in both Canada and the United States there is a one-year grace period for inventors. If you have made your invention publicly available, then you have 1 year in which to file your application. In Europe, however, if you have not filed an application for a patent, and you have made your invention publicly available, you would not be entitled to a patent.
Sometimes there are conflicts as to who will receive the patent foe an invention. In Canada and most jurisdictions around the world, the inventor to file an application will receive a patent. If there are 2 inventors who develop the same invention, the inventor who files the application first receives the patent.
