When you have spent time and energy in creating a new invention, you need to make sure you apply for a patent. A patent is “a government authority or licence conferring a right or title for a set period, especially the sole right to exclude others from making, using, or selling an invention”. As the definition explains, this protects your invention from being made by others or selling your invention under their name. If you do not apply for a patent you have no legal right to protect your invention, so if someone else copies your work and applies for a patent before you, it is likely to be considered their invention. When you have been granted your patent you will be covered for how the invention works, what they do and how they do it as well as the materials it is made from and how it was made.
