We offer Patent Drawings/Illustrations for your Patent Application

What are Patent Drawings?


A Patent Application often requires drawings or illustrations to aid the understanding of the technical features and assembly of the invention. The sheets of drawings should have as many views (Plan, Top, Side, Section, ISO Exploded) as is required to understand and aid the patent application fully.

IP AUSTRALIA manages patents and trademark applications in Australia as they have prior art knowledge of IP intellectual property. The requirements for drawing representations are:

There is no need for a specific number of views. However, one must provide good ideas to display the design, which usually requires several ideas fully.

We prefer traditional views (front, side and top) but will also accept perspective or isometric views. (See image below).

All views must show the same design. It mainly applies to colour, as colour is usually a visual feature of the design.

What can drafting Australia do to assist with your patent application?

Our Drawing/patent office works with patent lawyers as well as individual inventors. Our Patent Drawings & Illustrations are always by the guidelines set by the Intellectual Property Office. We use the best method or process, focusing on the advantages of the applicant’s benefits the most.

There are several vital points and requirements for all drawings

  • Draw accurately, without sketches, with well-defined linework.
  • Show only the design in question and no descriptive wording or dimensions.
  • The labelling of views like ‘perspective view’ or ‘rear views’ is acceptable.
  • A4 size paper if lodged by post.
  • Use broken or dashed lines when highlighting:
  • Use elements of the Product other than those bearing the visual features of the design.
  • Parts of the design refer to in the statement of newness and distinctiveness.
  • Boundaries like a pattern applied to part of a surface, stitching and perforations.
  • Features that establish an environmental context.

What information do we require to create a complete set of Patent Drawings?

We are able to create the drawings/illustrations from the following information:

  • Existing Products such as a Prototype
  • Hand Sketches in Image, PDF or Paper format
  • Existing CAD files in 2D or 3D

Creating a complete set of patent drawings requires careful attention to detail and adherence to specific guidelines set forth by the patent office where the application will be filed. Here’s the information typically required:

  1. Detailed Invention Description: A thorough description of the invention, including its features, components, and how it operates. This description serves as the basis for creating the drawings.
  2. Design Sketches or CAD Models: Initial sketches or Computer-Aided Design (CAD) models of the invention can be helpful in visualizing its various aspects and components.
  3. Technical Drawings: Detailed technical drawings of the invention, illustrating its various parts, dimensions, and configurations. These drawings should be clear, accurate, and labeled appropriately.
  4. Perspective Views: Drawings showing the invention from different angles and perspectives to provide a comprehensive understanding of its appearance and structure.
  5. Cross-Sectional Views: Cross-sectional drawings that reveal the internal structure and workings of the invention, particularly if it has complex components or mechanisms.
  6. Scale and Proportions: The drawings should be to scale, accurately representing the size and proportions of the invention. Measurements may be included to indicate dimensions.
  7. Annotation and Labels: Clear annotations and labels should be provided to identify each component of the invention and its relationship to other parts.
  8. Shading and Detailing: Shading, hatching, or other techniques may be used to distinguish between different materials, surfaces, or features within the drawings.
  9. Numbering and Reference Points: Each drawing should be numbered and include reference points to facilitate cross-referencing within the patent application.
  10. Compliance with Patent Office Guidelines: The drawings must comply with the specific requirements and guidelines set by the patent office where the application will be filed. These guidelines typically include rules regarding paper size, margins, resolution, file format, and other technical specifications.
  11. Consistency: Ensure consistency in style, line weights, and labeling throughout the set of drawings to maintain clarity and professionalism.
  12. Revision History and Document Control: Keep track of any revisions or updates made to the drawings to maintain an accurate record of the invention’s development.

How much do Patent Drawings cost?

At Australian Design & Drafting, we would quote a fixed price for Patent illustrations/drawings. We understand that inventions have very tight budgets. We provide a fixed-price quotation based on sketches or images.
