In addition, one needs to be meticulous in creating specific and detail-oriented patent drawings as there are particular rules and regulations in place for different patent offices. The additional importance of patent drawings services are shown below in Figure 6:<\/p>\n\n\n\nFigure 6: Importance of Patent Drawing Services<\/strong><\/figcaption><\/figure>\n\n\n\n\nSimplification of Complex Details: <\/strong>Explaining the working of new machines with several hidden cross-sectional areas can be a daunting task, even for the best of inventors with tons of experience. An examiner or ordinary observer who may not have the required technical prowess will find it challenging to grasp the invention with a textual explanation. That is why patent drawings come in handy to capture the intricate details of the invention more straightforwardly for better clarity. A professional patent illustrator is more adept at placing the drawings in the appropriate place to facilitate easy comprehension for the examiner or a general observer.<\/li>\n\n\n\nImproving Clarity of the Invention: <\/strong>The description of a new invention that consists of working of complex parts may not be easily grasped by an ordinary observer who lacks the necessary technical knowledge. Patent drawings for various angles can help them visualize the invention’s working in the real world. For example, the working of any mechanical or electronic device is best captured by illustrations to focus on the specific part of the invention.<\/li>\n\n\n\nAssisting in Patent Filing: <\/strong>While a utility patent is concerned with the feature and functionality, the design patent focuses on the aesthetic part of a product. Design patents are crucial for establishing the uniqueness of a brand, and it is best portrayed with the assistance of a drawing. A well-crafted drawing firmly shows the essence of design and strengthens a brand’s market position.<\/li>\n\n\n\nIncreasing Strength of the Claim<\/strong>: In the absence of neat and well-labeled patent drawings, there is a probability that the claim for the invention might be rejected. The examiner may not understand the invention’s novelty with the textual explanation and deem it unoriginal. Patent drawings that are placed at relevant places aid in boosting the claim of your invention.<\/li>\n<\/ol>\n\n\n\nAfter learning about the basic concept of patent drawings, one must also understand the various types of patent drawings and their features.<\/p>\n\n\n\n
<\/span>Types of Patent drawings<\/span><\/h2>\n\n\n\nThere are mainly three types of patent drawings as discussed below:<\/p>\n\n\n\n
\nUtility Patent Drawings:<\/strong> The purpose of utility patents is to protect the product’s functional aspects, i.e., how the article works and how it is used. Utility patent drawings help illustrate the following things \u2013 block diagrams, electric circuits, chemical formulas, flow charts, and line drawings showing the shape of objects. In an ideal scenario, the utility patent drawings must cover the entire element mentioned, at least in claims.<\/li>\n<\/ol>\n\n\n\nAlthough it is said that the task of preparing utility patent drawings is best left to the professionals, a basic understanding is still necessary for everyone involved. Some of the standards for drafting impeccable utility patent drawings are discussed below:<\/p>\n\n\n\n
\nLines Numbers and Figures:<\/strong> The utility patent drawings submitted in patent applications are black and white line drawings with solid and secure black lines. There is more relaxation allowed while filing the provisional applications. Every sheet and figure has to be numbered consecutively, and the text should be at least 1\/8 inch in height for better readability upon reduction. The two commonly used sheets sizes for drafting patent drawings are A4 and Letter. The majority of the drafting companies use the default sheet size unless directed to use a specific size.<\/li>\n<\/ul>\n\n\n\n\nLead Lines: <\/strong>In utility patent drawings, reference numbers are used for correlating a feature to a written description of that feature. To facilitate a better understanding for the examiner, a lead line or other indicator is used to link reference numbers and features. The rule of the thumb regarding lead lines is that they should meet the object, surface, or line identified at a right angle.<\/li>\n<\/ul>\n\n\n\n\nAesthetics and Improving Legibility<\/strong>: While preparing the utility patent drawings, it is critical to take care of the symmetry. A symmetrical drawing improves the aesthetics and increases its readability and understanding. A utility patent drawing should be easy on the eye so that interpretation of the main points of the drawings becomes easier.<\/li>\n<\/ul>\n\n\n\n\nFlowcharts: <\/strong>Symmetry and consistency are also important while incorporating flow charts for utility patent drawings. The lines and the boxes used in the flowcharts should have the same thickness, color, and size to avoid confusion in the mind of general observers. In addition, the arrow length should be the same to maintain the same distance between two consecutive blocks. A symmetrical and balanced flowchart is successful at delivering the desired message. Figure 7 below shows an example of a utility patent drawing.<\/li>\n<\/ul>\n\n\n\n

Design Patent Drawings:<\/strong> Compared to utility patent drawings, a design patent drawing only protects an article’s ornamental appearance, such as its shape, surface ornamentation, or configuration. It covers the aesthetics of a functional item. Some examples are furniture, jewelry, beverage containers, and computer icons. The shading in design patent drawings must be clear to reflect the invention’s contour, shape, and material textures. Unlike utility patent drawings, design patent drawings do not have reference numbers. Some of the requirements for drafting a clean design patent drawing are listed below:<\/p>\n\n\n\n\nColor of Design Patent Drawings: <\/strong>The drawings must be illustrated in black and white. Special care has to be taken for any surface shading to project the character and contour of all surfaces related to the 3D aspect of the design. Broken lines are utilized to indicate portions that are not a part of the claimed design. For special cases, black and white photographs can be used in place of ink drawings if photographs are the only way to illustrate the invention. However, applicants must file a petition and seek approval to file colored drawings or photographs in place of black and white drawings.<\/li>\n<\/ul>\n\n\n\n\nDesign Patent Drawings Views: <\/strong>The drawings of the design patent should cover the following views \u2013 front, rear, right side, left side, top and bottom. All the views should be presented head-on and not from a particular angle. Views presented from an angle are called perspective views and are not mandatory in patent applications. In case the two views are mirror images of each other, then one of them can be removed. However, it is better to provide a statement confirming that the other side is a mirror image of the one highlighted in the drawing. The bottom view can be omitted if the bottom is flat and has no ornamentation. However, the figure description must include a statement emphasizing the point that the bottom is flat and unornamented. The surfaces that are not flat should not be described as unornamented. <\/li>\n<\/ul>\n\n\n\n
Figure 8: Example of a Design Patent Drawing<\/strong><\/figcaption><\/figure>\n<\/div>\n\n\n3. Plant Patent Drawings:<\/strong> A plant patent protects the critical features of a plant from being copied or used by others. Plant drawings are generally reproduced in other mediums, such as permanent watercolor renderings that truly capture the appearance of the plant. These drawings are not mechanical in nature and must be well-drafted to highlight their unique characteristics. A large number of inventions are easily understood with the inclusion of patent drawings in patent applications. Plant patent drawings may be in color. However, the color portrayed must also match the respective color designation defined in the color dictionary specification. Usually, two copies of the color drawings are submitted in a patent application.<\/p>\n\n\n\n
