Frequently Asked Questions

What are the international requirements for filing a patent?

Filing a patent internationally involves adhering to certain requirements that vary depending on international agreements and national laws. Generally, a patent application must include one or more claims that establish the invention as unique. These claims should be useful, non-obvious, and novel. Each claim should designate a specific property right that can be protected. The World Trade Organization (WTO) mandates that all its member states must allow patent protection for all inventions in all technical fields for a minimum of 20 years. However, individual nations maintain their own laws about what inventions can be patented. The inventor must be the one to file the patent, and the invention must be useful, marketable, novel, and non-obvious. It should also fall into one of the four general patent classes: articles of manufacture, processes and methods, compositions of matter, and machines. Certain inventions, such as abstract ideas, laws of nature, non-useful objects, or physical phenomena, are not eligible for patent protection.
