On 7th July, 1934, Philips Screw Company was awarded with a patent over this invention. The patent was awarded by USPTO with registration number US2046837.
This is not the first patent which was granted to screw driver. The original inventor of this invention is P. Thompson. He transferred all the rights to Henry F Phillips, who later on went ahead to form a Company, named Phillips Screw Company. They later on did improvements on the invention and claimed Patent protection over those. This Patent was granted for one of the improvements.
