Double patenting of the same invention occurs when an individual attempts to obtain a patent for an invention that has already been patented by the same individual. This is prohibited as it would grant excessive control over the invention to the individual. It is akin to obtaining two driver’s licences for the same vehicle, which is unjust to others who may also wish to utilise the invention.
Same-invention double patenting occurs when an inventor attempts to obtain two patents for the same invention, which is prohibited due to the unfair advantage it would give the inventor over others. For instance, if an inventor applies for a patent on a new type of phone and then seeks another patent for the same phone under a different name, this would be considered same-invention double patenting. This practice is not allowed as it would result in the inventor having an unfair advantage over others who wish to use the phone, as they would be required to obtain and pay for two separate patents.
Same-invention double patenting refers to a situation where an inventor seeks to obtain multiple patents for the same invention.
