How to cite a patent in APA Style
A patent is a legal document acknowledging an invention as the intellectual property of its inventor. Though they fall under legal materials, references for patents follow standard APA Style, rather than the legal style used for things like court cases and laws.
To cite a patent in APA Style, list the name of the inventor, the year it was issued (in parentheses), the title of the patent (in italics), the patent number, the name of the issuing body, and the URL if available.
|Format||Inventor name, Initials. (Year). Title of patent (Country/Region Patent No. Number). Issuing Body. URL|
|Reference list||Ghatak, S. (2019). Immunization testing system (U.S. Patent No. 10,788,482). U.S. Patent and Trademark Office. https://rb.gy/ik0fb0|
|In-text citation||(Ghatak, 2019)|
