How to Cite a Patent? Major Citation Styles Explained

To cite a patent is not to decode legal jargon. That is not how it is supposed to feel, at least. Writing an academic paper? Filing legal documentation? Publishing technical research? A wrong citation format can weaken your credibility. This article breaks down patent citations and keeps it simple and clear.

How to Cite a Patent in Various Formats?

There is no single set method of patent citation. A list of formats is available to choose from. You can use one that fits your patent the most. A patent can be cited in the following formats:

  • ACS
  • AMA
  • APA
  • Chicago
  • CSE
  • IEEE
  • MLA

ACS (American Chemical Society)

The ACS style format is adopted by those who are in the field of academia associated with chemistry. Two components make an ACS citation:

1. Showing identifiable information or data within the patent text.

2. A source list which references a whole biography.

An Example of ACS Citation:

In-Text Citation:

(Mike US Patent 1,378, 436 B3)

Bibliography/References Section:

Mike, M. R. US Patent 1,378, 436 B3, [Year of Issue]

AMA (American Medical Association)

You will need to consider the following to cite a patent in the AMA style:

  • The inventor’s name
  • The assignee’s name
  • A title or description of the patent (no italics)
  • The number assigned to the patent
  • The date of patent publication

An example of the AMA 11th Edition Patent Citation:

John AK and Ryan BD – names of the inventors

Method and Apparatus for Robotics Security – title of the patent

US Patent 0,309,766 – the patent number

November 1, 2022 – the publication date of the patent

APA (American Psychological Association)

Academic papers, articles and books included, use the APA format for patent citation. The 7th edition of APA citation has the following guidelines that one must meet:

  • The inventor’s name
  • The year when the patent was issued
  • The patent title (a description if there is no title: in italics)
  • The patent number
  • The issuing body name/title
  • The URL (if available and applicable)

An Example of APA 7th Edition Patent Citation:

Elijah, F. K. (2018). Method and apparatus for robotics security (U.S. Patent No. 5,234,567). [URL]

Chicago

You need the following to cite a patent in the Chicago Manual of Style (CMOS):

  • The inventor’s name
  • The patent title
  • The patent number

An example of the Chicago 17th Edition Patent:

James, C. D., and Henry, A. S. “Information Security System Using Artificial Intelligence Techniques.” U.S. Patent 7,234,569, July 15, 2018.

CSE (The Council of Science Editors)

The CSE style guide is to be used with natural sciences such as biology, geology, physics, and chemistry. There are two formats CSE can work with:

  • The sequence/citation format
  • The name/year format

Both formats demand the following essentials:

  • The author’s name
  • The inventor’s name
  • The assignee’s or patent holder’s name  
  • The title/name of the patent
  • The country that issues the patent and the country code patent number (add commas)
  • The patent publication date (Year/Month/Day)

An Example of CSE 8th Edition Patent Citation:

Benny, AQ, Joe, C.S. Secure Online Private Communication with End-to-End Encryption. US Patent 7,012,345. May 12, 2022.

IEEE (Institute of Electrical and Electronics Engineers)

The IEEE citation style does not have any citations. Still, the following guidelines must be adopted:

  • The inventor’s name, including initials or first name and surname (periods and spaces between first name and middle names)
  • The patent title
  • The U.S. patent number
  • The patent publication date (Month, Day, Year)

An Example of IEEE Patent Citation:

H. S. Helly and H. B. Moe, “Efficient Machine Learning for Network Protection,” U.S. Patent 3,234,567, December 14, 2017

MLA (The Modern Language Association)

The MLA style is prioritized for scholarly texts. The general guidelines that must be followed are:

  • The inventor’s name
  • The patent’s name/title
  • The issuing agency
  • The issue date (Day/Month/Year)

An Example of MLA Patent Citation:

Ben, Jay R. US 2,474,807, Cryptographic Breakthroughs for Data Security, United States Patent and Trademark Office, 11 July 2020.
