Citing patents accurately and effectively is crucial for both academic research and legal documentation. It allows you to properly acknowledge the inventors and their contribution to the field while providing readers with the necessary information to access the patent document. This guide will walk you through the process of citing patents in different formats, including legal citations, academic citations, and general referencing.
Understanding the Basics of Patent Citations
Before diving into the details, it's essential to understand the fundamental components of a patent citation. Typically, a patent citation includes the following information:
- Patent Number: This unique identifier distinguishes the specific patent from all others.
- Patent Type: This clarifies the type of patent, such as "U.S. Patent," "European Patent," or "PCT Patent."
- Publication Date: This indicates the date the patent was published.
- Inventor(s): The names of the individuals who invented the subject matter of the patent.
- Assignee(s): The entity or entities that own the patent rights.
- Title: A brief description of the invention covered by the patent.
Legal Citations: The Standard for Legal Documents
Legal citations are crucial for court filings, legal briefs, and other formal legal documents. These citations adhere to specific rules and formatting to ensure clarity and consistency. Here's how to cite a patent in a legal document:
Example:
- U.S. Patent No. 9,000,000, issued to John Doe, assigned to Acme Corporation, entitled "Method for Making Widgets" (Jan. 1, 2015).
Key Elements:
- Start with "U.S. Patent No." followed by the patent number.
- Specify the inventor's name followed by "issued to."
- Include the assignee's name followed by "assigned to."
- Provide the patent title within quotation marks.
- Finish with the date of issuance in parentheses.
Tips:
- If there are multiple inventors, list them all, separated by commas.
- If the assignee is not known, omit this information.
- The date format should follow the standard used in legal documents.
Academic Citations: Referencing Patents in Research Papers
Academic citations are used in research papers, dissertations, and other scholarly works. Different academic styles (MLA, APA, Chicago, etc.) have specific guidelines for patent citations.
Example (APA Style):

- Provide the patent title in italics.
- Mention the patent number after the title, preceded by "U.S. Patent No."
- The citation should be formatted according to the chosen academic style.
Tips:
- If the patent has a published abstract, you may include it after the title.
- If the patent is referenced in a legal case, you can include the case name and citation as well.

When citing patents in non-legal or non-academic settings, you can adapt a simplified citation format for clarity and ease of understanding.
