Key Takeaways:

  • A U.S. patent is a legal document that gives an inventor exclusive rights to their invention for a limited period, typically 20 years from the filing date.
  • Patents include distinct sections: abstract, background, summary, figures, embodiment, and claims. These sections define the scope and enforceability of the invention.
  • Patents can cover utility inventions, designs, or plant varieties, and each type looks slightly different in formatting and content.
  • Official patents display identifying features such as patent numbers, issue dates, inventors, and INID codes, allowing them to be distinguished and referenced internationally.
  • Sample patents often include labeled drawings, numbered claims, and government headers, which visually communicate the protected invention.

What does a patent look like? A patent is a legal title that grants an inventor the right of excluding others from selling, using, or making/reproducing a certain invention. In the U.S., the duration of a patent is 20 years from its filing date. Patents are granted for new inventions, machines, processes or composition of matter, or new improvements thereof. In this instance, “composition of matter” refers to chemical compounds, including new compounds and mixtures of ingredients.

Patentable Inventions

To determine if an invention is patentable, it must be relatively new as defined by patent law. Inventions that have been on sale, used by the public, or described in printed publications for over a year cannot be patented. Inventors can submit a patent application for the same invention in multiple countries.

Patenting organizations that publish patent applications include the WO, WIPO (World Intellectual Property Organization), and the EP (European Patent Office). Such published applications provide detailed information on inventions before they appear in U.S. patents.

Propagation of New Technologies

The patenting system was designed to propagate new technologies by publishing lists of new inventions and their full details. As such, patent documents are important sources of information for researchers.

For an invention to be patentable, it must possess these basic criteria:

  • It must be useful.
  • It must be novel.
  • It must be non-obvious.

Filing a Patent Application

For an invention to be protected, it must be filed either with the patent authority in that country or with one that the country acknowledges. For instance, filing a patent with the United States Patent and Trademark Office offers no protection for the invention in Asian or European countries.

Drafting Patent Applications

Patents are legal documents that describe an invention and the idea behind the invention. Drafting a patent application requires the services of an experienced patent attorney; otherwise, you get a legal document that is imprecise or vague and therefore difficult to enforce.

Format of Patent Applications

All patent applications and patents are generally in this format:

Abstract

This contains a summary of the invention. The information to be written here should help other persons quickly understand the nature of the invention. It is important to note that this section should contain a much broader description of the invention that the claims section. The claims section is what defines the actual limits of the patent's coverage.

Background

This describes the problem as well as any solutions currently in use. Do not describe your solution or invention idea at this point since it may be considered as prior art.

Summary of the Invention

Provide a summary of your novel idea or invention and how it solves the problem stated in the last section.

Figures

Include all diagrams and drawings that illustrate the invention. A qualified patent attorney can assist in the drafting of professional patent drawings; however, hand-drawn diagrams are not unheard of in patent applications. The main point to note is that the diagram must explain the idea clearly.

Embodiment

Describe how the invention or idea can be implemented. For instance, if the idea is the use of electromagnetic in an automotive transmission, you should explain the steps required to construct such a transmission. The major objective of this section is to show the workability of the invention.

Claims

At this point, you assert the right to the specific idea or invention mentioned above. This section requires care since you must ensure that all the core ideas behind the invention are claimed else you may not get the level of protection you seek.

An experienced patent engineer and patent attorney can help you come up with a comprehensive set of claims for the patent. The claims section is very important since a law court will rule based on the information contained here (in the event of a patent infringement).

Visual Elements of a Patent

When asking, what does a patent look like, it helps to understand its visual components. A U.S. patent document typically begins with a government header showing the patent number, type of patent (utility, design, or plant), and issue date. Beneath this header, you’ll often see:

  • Inventor and Assignee Information: Names and addresses of the inventor(s) and the entity that owns the patent.
  • Patent Drawings or Figures: Labeled illustrations that depict the invention or its design. For utility patents, these often include schematics or functional diagrams. For design patents, the drawings are the core of the protection.
  • Abstract and Summary Sections: Positioned near the front, summarizing the essence of the invention.
  • Claims with Numbering: Usually found toward the end, claims are numbered sentences that legally define the invention’s scope.

Patents issued internationally follow a similar visual format, though layout and language can vary. INID codes (Internationally Agreed Numbers for the Identification of Data) are standardized numeric labels printed near the bibliographic information to identify sections like inventors, filing date, and application numbers.

Identifying Patents

A patent's INID Codes can be found on all printed patents worldwide. It allows individuals to identify information elements in a patent. In most cases, an issued patent will be designated as “United States Plant Patent,” “United States Design Patent,” or just “United States Patent.”

Examples of Patent Appearance

Understanding what a patent looks like is easier with examples:

  • Utility Patent Example: Shows detailed drawings labeled with figure numbers, descriptive specification pages, and a claims section.
  • Design Patent Example: Features multiple perspective drawings of the product; the drawings largely define the legal protection.
  • Plant Patent Example: Includes color photographs or illustrations of the new plant variety along with a short description.

Most patents issued by the USPTO include:

  1. Front Page Information: Patent number, filing and issue dates, inventor and assignee, classification codes.
  2. Drawings/Figures: Labeled to match references in the written specification.
  3. Specification: Detailed written explanation that references the drawings.
  4. Claims: Sequentially numbered sentences that determine the patent’s enforceable scope.

Viewing sample patents from the USPTO or legal resources like Neustel Law Offices can help inventors visualize the standard format and requirements before filing.

Frequently Asked Questions

1. What does a U.S. patent look like? A U.S. patent is a multi-page document with a front page showing the patent number, inventor names, and filing details, followed by drawings, a written specification, and numbered claims.

2. Do all patents include drawings? Most utility and design patents include drawings. Plant patents include illustrations or photos, while some simple utility patents can have minimal figures if the invention is easily described in words.

3. What section of a patent defines the legal rights? The claims section defines the patent’s enforceable scope. Courts rely on these claims to determine infringement.

4. How can I tell if a patent is official? Official patents include a government header, a patent number, and INID codes on the front page. They are published by a recognized patent office, such as the USPTO.

5. Where can I see sample patents? You can view sample patents on the USPTO database, Google Patents, or law firm sites like Neustel, which provide examples of utility, design, and plant patents.
