USPTO design patent drawings disclose the ornamental appearance claimed for an article. Prepare a consistent set of views and check the sheet format, line treatment and figure descriptions before filing. The requirements concern both what the figures show and whether the filed drawings reproduce clearly.

If your source materials need organising into consistent figures, discuss a drawing-set brief with Menteso.

USPTO Drawing Margins and Sheet Size

Under the drawing standards summarized in MPEP 507, use A4 sheets (21.0 × 29.7 cm) or U.S. letter sheets (21.6 × 27.9 cm). Minimum margins are 2.5 cm at the top, 2.5 cm at the left, 1.5 cm at the right and 1.0 cm at the bottom. Keep the usable drawing area within these limits.

Check the final exported document at its intended page size. A drawing that fits in a design application can still be clipped or scaled incorrectly during export. Distinguish drawing-sheet standards from the separate formatting requirements for written application papers.

Views That Disclose the Design

Plan enough views to disclose the design clearly, commonly including perspective and appropriate front, rear, side, top and bottom views. Review justified omissions and descriptions with the responsible practitioner. Confirm that shared features align across views; do not let a perspective rendering contradict the orthographic set.

Lines, Shading and Unclaimed Subject Matter

Clear line work and appropriate surface shading help communicate contours and surfaces. Broken lines may depict subject matter that is not part of the claimed design, with the required explanatory treatment. Decisions about claimed and unclaimed features should follow the filing strategy and professional review rather than a draftsman’s assumption.

The USPTO design patent application guide explains drawing disclosure, shading, broken lines and the special requirements for photographs or color material. Check those rules before substituting photographs for drawings or preparing a color submission.

Design Drawing Review Checklist

Compare all views against the same approved source model or photographs. Check feature consistency, figure numbering, descriptions, shading, margins and final legibility. Keep revision notes so the reviewer can see which features changed and why. Resolve ambiguity before filing: later corrections cannot simply add missing disclosure.

A design patent concerns ornamental appearance; a utility patent addresses functional inventions. Use the patent application guide to compare preparation steps. For drawing support, review Menteso patent drawing services and send a brief describing the article, available source material, intended office and required views.

A patent is a right that is granted to the inventor. Before applying for design patent, an inventor must identify which type of patent their invention is.

Types Of Patent are:

1. Utility Patents: It covers the invention of a new or improved product, process, or the machine. 
2. Design Patents: This patent right is granted to inventors that have invented a new, ornamental design for an article of manufacture. 

Before applying for a patent, inventor and startups should ask three questions to themselves:

These 3 questions will help you to decide when you are ready to file a patent for your invention:

1. What makes my invention new?

Take a good look at all the related products and technologies and determine what makes your invention different from everything else. It will give you a better understanding of your invention’s value.

2. Is Your Invention or Idea Novel?

Before filing a patent, you have to know more than what is new about your invention or idea. You have to know that if your invention is novel or not.

3. Are You Ready to File a Patent Application for your invention?

Before filing a patent, be assured that you have a good idea of your invention’s novelty and if you have sufficient of a patent application to persist patent prosecution. This will help you to file the best patent application that you can.

So here are the top tips you should know before applying for patenting invention:

1. Work in an inventor’s notebook: It is a great way for documenting and measuring progress as you test and refine your designs.

2. Do market research: Take the time to do your research to see if your idea is even worth it. These few simple questions you can answer by visiting your local stores or doing some online searches.

• Will your product sell?
• To whom?
• Where? Online? At stores? 
• How will it be sold? 
• At what price? 
• Who is your competition?
• Why is your product idea different?

3. Admissions – Be careful with what you say: One big problem independent startups and inventors face when they choose to express themselves is concerning the very real obstacle of admissions. Those who are expressing themselves should be given relevant references before they file a patent application or say anything during the prosecution of a pending patent application. Everything the inventor does say can be used against them.

4. Determine whether your concept has passed the invention barrier: We cannot patent an idea. The solution is to take that invention idea, test it, refine it, redesign that idea. Every step will take you closer to a tangible invention that is patentable.

5. Acquire and use a non-disclosure agreement: Non-disclosure agreements are contracts that can be used to defend against infringement in ways that a patent cannot.

6. Join an inventors group: It will give you access to the people just like you. 

7.  Make a simple prototype or mock up of your invention idea: It will help you explain clearly how your invention works and how it solves queries for potential customers. 

8. Make sketches and 3D models of your invention: It will help you tweak and make adjustments to your invention. It is an inexpensive way to present ideas without having to make a perfect prototype.

9.  Learn about the processes your product will need to be manufactured: Learn about the expenses of manufacturing your product or invention. Visit maker places in your area. Talk to people in the industry your product is concerned. Before researching the process you are inquiring about, make your first phone call for getting even a rough idea of what is going on that will help you ask the right questions and get the most out of every intercommunication. 

10. Get a design for manufacturing/design for assembly (DFM/DFA): If you’ve done your market research, understand the processes and costs necessary to produce your invention, and have a basic design for how your invention will work, you now need to have an expert design it specifically for the process in which it will be manufactured.

11. If necessary, file a provisional patent application (PPA): Provisional patent drawings can be your friend. This will give you some time to work on your invention and show manufacturers, investors, and others that you know the process and are serious about guarding your intellectual property. You can also search for a lot of information online about provisional patent applications. 

12. If you fear being specific don’t seek a patent:  If you are afraid to be specific in a patent application then you really should not be seeking a patent in the first place. Instead, you should be keeping what you have invented or what is your invention to yourself as a trade secret to the greatest possible extent.

What else you need is to include additional fees for filing, search, and examination purposes.

Get a brief understanding of the patent illustrations techniques and its importance in protecting the appearance of your inventive idea. 

An inventive idea is better defined when its information is accompanied by a comprehensive and accurate illustration. A visual depiction of any invention or idea helps the patent examiners understand what it’s all about.

Various categories in which ideas can be depicted noticeably & professionally.

• Design Patents (ornamental design of a functional item for which legal protection has been granted).
• Utility Patent Drawings.
• Software-related Patent drawings.
• Trademarks Patent Drawings.
• DNA (DNA structures, DNA Chain links, DNA coding).

Patent Illustration Techniques that will help you to adopt a better patent filing methodology:

• Patent Drawing in the traditional method: Drawing with pen, ruler, and instruments used by the people down by the ages.
• Patent Drawing in modern method(2D 3D modeling tools): There are several reliable and advanced patent drawing software available now that provide a lot of advantages and functionality which improves the overall patent designing experience.

1. AutoCAD – Most reliable commercial computer-aided design and drafting software. 

2. MS Visio – Used to draw a variety of diagrams including flowcharts, floor plans, data flow diagrams, and building plans, 3D Maps, and more. 

3. CorelDRAW – Used by professionals in designing logos, brochures, cards, and any other kind of vector designing. 

4. Autodesk Inventor – Used for 3D mechanical drawings 

5. SolidWorks – Used solid modeling program that enables designers to create models, assemblies, and parts in the most professional and reliable way.

Role Of Patent Illustrator

Patent Designers are technical and creative persons that are well aware of the different tricks and techniques used in patent illustrations with high precision and accurate technical details. 

They have a thorough knowledge of filing requirements for patent drawings at the United States Patent and Trademark Office (USPTO), European Patent Office (EPO), and other global patent offices.

A patent illustrator comes up with multiple views of those products that describe the invention perfectly. 

Compared to the traditional method of patent illustration, the modern method & advanced patent drawing software helps to make stunning and accurate illustrations easily in less time.

From the above discussion, Patent illustration techniques and importance will help you to employ which methodology to patent your inventive ideas

If you’re an enthusiast inventor who believes in giving wings to your creativity then you might need patent illustration services when you’re about to draft your claim. 

You need to describe your invention with precision through non-provisional patent drawings, which can be made by hiring professional illustration service providers. 

The purpose is to ensure that your invention is quite different from all the inventions that were earlier patented and eventually provides value to solve an issue. 

Here’s a quick introduction regarding patent illustrations and why you need professional technical illustration services. 

You can Achieve the Best Disclosure through Patent Drawings: 

Your patent drawing is quite useful in the way that it offers a reference to the readers who are going through your description of the patent. You can showcase several features and functionalities in the drawing of your invention, which is essential to get your patents approved while submitting. 

You must rely on professionals with years of experience in providing the finest patent illustration services that further ensures your patents aren’t getting rejected. You can explore the internet to find the most reliable services as per your business requirements. 

You have to Ensure Patent Drawings follow the Regulation:

Many people aren’t aware of the fact that the design patents must strictly follow a particular requirement. These regulations state that every patent must be drawn on a particular sized sheet along with precise margins and the type of paper should be given proper emphasis. So, you must be very careful while you’re choosing your patent drawing service provider to ensure everything is up to the mark and you have a greater chance of getting approval. 

How to Find the Best Illustration Services 

You can always find the best service providers when you need to file a patent for your invention by researching the internet. The ones with better reviews and adequate years of experience can be considered for your patent needs. You can always go through the feedback of clients to know more about the overall quality of services delivered by a service provider. 

Whenever you’re about to submit a patent, it’s crucial that your application stands out of the league and must depict everything in detail. 

No matter if you’re submitting an engineering drawing or utility drawing for any invention, your drawings play a significant role in getting approval. 

But most of the time you may be confused between two terms- Utility Drawings patents and Design Patents. People aren’t able to decide which is better when compared. 

But the real distinction between utility and design patent is usually the difference in protecting design (how it looks) vs. utility (how it works). 

Design patents are ornamental design which is usually considered by those who are concerned about their competitors who may copy their design. One can apply for a design patent if they want to ensure that their designs remain unique and no one could copy them. 

On the other hand, if your main focus is on protecting the features and functionality of your new concept, you must apply for utility drawings patents. Although, some cases may require the applicant to file utility and design patent applications. Submitting a design patent or utility patent entirely depends on your project and overall requirements. 

As per the industrial experts, it is important to understand the aspects that may lead to the rejection of your patent. This simply means you must consider relying on design patent professionals that can lend a hand in providing the best designs that have a higher chance of getting approval. 

So, it’s always a great decision to seek professional help whenever you’re about to submit your patent application form. 

Drawings are perhaps the most crucial part of your design patent applications, which describe your utility patent or application quickly. You need to ensure that your drawings must depict what is being claimed in an invention. 

Some people ignore the importance of utility patent drawings, which shouldn’t be done since your drawings provide the complete meaning of your patent, which otherwise could be quite difficult to understand. 

So, you just can’t neglect the importance of drawings if you wish to describe clearly what your utility patent is. Let’s have a quick look at the utility patent drawing requirements.

Patent Application Process Rules 

If you are about to submit a patent drawing and unsure about the overall process rules, here’s the list of rules that you must strictly follow while submitting a patent drawing. 

• Always prefer black and white colors.
• Your drawing must include the application number along with other crucial details including- applicant’s name, inventor’s name, and inventor’s identification. 
• The size of the application drawing must be 11×8.5 inches and should be in white. Also, it must be flexible, non-shiny, and plane.
• Avoid solid shading. You can always prefer patterns
• Make sure you use correct numbering as per the guidelines for every part. 

Guidelines by USPTO

It is always a great decision to go through the guidelines offered by USPTO to better understand the overall process of submitting your application for utility patent drawings. Here’s what you need to focus on:

• Ensure your drawings are neat and clean and must have clear depiction through adequate use of numbers, symbols, texts, and graphs. 
• You need to invoke the potential of your creativity to make the drawings more appealing. 
• Make sure that there should be no overwriting and the entire drawing should be neat and clean while you are submitting. 

These are some of the requirements that the inventor must keep in mind while submitting utility drawings. Furthermore, it is advised to consider consulting professional utility patent drawings services if you face any issues in creating patent drawings for your invention. 

Hiring professional service providers is a great way of ensuring that your patent drawings get quick approval, which further saves your time and effort. 

Receiving a rejection for your patent application could be the most disheartening thing. You may spend long hours designing your patents but knowing that it isn’t up to the mark could be quite annoying.  

Many reasons may lead to a rejection of a design patent application. It’s important for you to understand the reason behind the rejection and to work precisely on improving your application. 

Whether it’s inconsistency or ambiguousness, one simply cannot expect their application approval if they haven’t put their best efforts. 

Here we’ll be discussing the top rejections for design patent applications that can be avoided by considering a few crucial aspects. 

102 Rejections 

If you are expecting a patent on innovation in the United States, it’s crucial to understand the legal requirements that would decide whether your patent would be approved or not. 

Most of the patent application drawings could be rejected under 35 U.S.C. § 102 if there’s a single preceding reference match every element of your application’s claim. 

Reports claim that 102 rejections are quite consistent over every technology center. Mechanical engineering as well as the manufacturing industry is widely impacted more than the other industries. 

You can always seek professional help if you’re not aware of submitting a patent drawing for manufacturing or mechanical engineering. 

103 Rejections 

The § 103 rejection could be caused if the invention doesn’t have a non-obvious improvement as compared to the prior art. The examiner may consider the invention to be obvious and the applicant is asked to further improvise the design. 

This 103 rejection is mostly seen in the field of computer networks, security, or cryptography. It is always a great decision to hire professional patent drawings services if you’re facing issues in submitting your patent application. 

These professionals could surely help you in submitting your patents and minimizing the chances of rejection. 

112(b) Rejections

Another common rejection is the 112(b) rejection, which can occur is the claims aren’t setting forth the subject matter that is claimed to be the invention. Moreover, the claims should essentially point out along with a proper definition of the subject matter, which is to be protected. 

Again, seeking professional help could be the game-changer if you’re still unable to understand the issues with your patents. 

Patent drawings play a crucial role in enhancing your brand repute whenever you’re about to submit your patent ideas. 

But are you aware of the software and overall process involved in creating patent drawings? If your answer is no, you’ve landed at the right spot! 

There are several professional tools that are being utilized by avid designers across the world. These tools and software provide a lot of advantages and functionality that improves the overall patent designing experience. 

Here we’ll introduce you to the software that is used in making patent drawings and how they help you depict your ideas noticeably & professionally.

AutoCAD 

It’s one of the most reliable commercial computer-aided design and drafting software, which is designed by Autodesk. It has an internal graphics controller to create 2D or 3D drawings with the help of layering and thus providing professional drawing capabilities. 

MS Visio 

Microsoft Visio is professional software that is used to draw a variety of diagrams including flowcharts, floor plans, data flow diagrams, and building plans, 3D Maps, and more. 

It helps the user to precisely craft diagrams, visuals, and graphs that flawlessly depicts the detailed information about a product. 

CorelDRAW 

CorelDRAW is designing software that is entirely vector-based and is used by professionals in designing logos, brochures, cards, and any other kind of vector designing. 

It’s one of the most preferred designing software utilized by professional graphic designers to design patent drawings. 

Autodesk Inventor

Autodesk inventor online can be used for product simulation, mechanical drawing, and other designing purposes for engineering. 

It’s a dimension driven computer-aided design, which is used in visualization simulation and also for documentation.

SolidWorks

SolidWorks is a widely used solid modeling program that enables designers to create models, assemblies, and parts in the most professional and reliable way. 

Models in this application are first created in 2D sketches and later can be extruded into 3D by using a variety of SolidWorks tools. You can also upload the solidworks patent drawings on our website, created with the solidworks.

These are all the tools that are used widely by professional designers to give wings to their patent design ideas.

All patent offices have their patent drawing rules that should be followed stringently while filing the patent applications. We will discuss the EPO Patent Drawing Rules requirements of the European Patent Office.

EPO (European patent Office) has set patent drawing rules for drawings, photographs, diagrams, and flowsheets that you must follow while generating drawings for the patent application. If you do not follow the patent drawing rules, you might get the unnecessary objections from the examiner. These unnecessary objections will increase grant time for your patent. A great patent drawing is one that doesn’t raise any examiner query. And for a set of great patent drawings, you need an expert patent illustrator.

EPO Patent Drawing rules: Important Points

You must follow EPO Patent Drawing Rules for cutting down office actions, saving costs, time, and efforts. Following patent drawings rules are the source for first-hand rejection of the patent drawings and thus your patent application:

Color Drawing Rules of European Patent Office

Black and White Patent Drawings:

As per the EPO patent drawing rules, the EPO requires black and white drawings. You can use black printing ink such as India ink when you are printing the drawings on paper. You need to make sure that when the drawings are made using any software, the drawings are generated using only black color. It is to be noted that the other colors when printed in black and white can give different shades of grey color.

Black and White Photographs:

Photographs are possible as per the EPO Patent Drawing Rules solely when they are the only available medium for illustration of the invention. The examples of photograph eligible patent illustrations could be chemical structures, cell structures, or beauty products, etc.

It is to be noted that the photographs should be of high quality so that they can print every detail when they are printed in black and white format.

Colored Photographs:

A Color photograph is acceptable only when you satisfy the conditions for the acceptance of black and white photographs. Also, the color photograph should satisfy the condition of color drawings.

Colour Drawings:

You must use color drawings only when you have no other choice. The color drawings’ quality should be very high. The examiner or the patent office should be able to print every detail of the color drawing in black and white format. Please note that the color drawings are prohibited in international applications. They may be allowed only when they are the only medium to express the details of the invention.

If you wish to use color drawings in your application, you must file a petition with the EPO. Your petition must explain the significance of the color drawings. The EPO patent drawing rules allow color drawings only after the grant of the petition.

The inclusions of color drawing petition are:

1. Petition Filing fee.
2. A black and white photocopy of the color drawing with similar details and 3 sets of color drawings.
3. Your drawing description must include the following paragraph: “The patent or application file contains at least one drawing executed in color.

Perspective Views

Also, you must include one or more perspective views of the invention. Further, try to keep one view on a sheet. However, you are permitted to include more views on a sheet. We do not recommend more than 2 views on a sheet for better clarity. In addition, try to avoid wasting sheets, keep the position, and maintain a proper gap between the views.

NOTE: Do not use similar sheets for views and claims.

Some other important views are included below. These views become important when you need to give more specific details about your invention.

Exploded Views:

Exploded views show the working, order, or relationship of an assembly of different parts. You must place an exploded view within the brackets. Read Patent Drawing Exploded Views for more information on exploded views.

Sectional Views:

A sectional view is used to show a hidden area or part of an object by cutting/removing some of the parts of that object. The cutting line is termed as cutting plane. Read Patent Drawing Sectional Views for more details.

Use of Scale in Patent Drawings

You must create a drawing with a scale that shows the mechanism of the invention without crowding. Further, you cannot use indications like actual size or scale 1/2 on the drawings.

Drawing Surface Shading requirements:

Drawing Surface Shading indicates the surface conditions or shape of any object. Spaced lines are preferred for shading. They must be thin, few in number and must contrast with the rest of the drawing. Further, you can also use stippling shading, however, that shading is generally recommended for design patent drawings.

In addition, you must assume the Light coming from the upper left corner at an angle of 45° for shading. Pitch black shading is prohibited. However, you may represent bar graphs with them.

Consider Reading: Patent Drawing Symbols for Draftsmen, the topic includes symbols for surface shading.

Drawing References:

• Use the English alphabet for references. However, to depict wavelengths, angles, and formulas, etc. you may use other kinds of alphabets.
• Keep legible reference characters such as sheet or view numbers. You should avoid using brackets or inverted commas.
• Keep the size of Numbers and letters to a minimum of 0.32 cm in height. You must place them at a clear surface and avoid placing them over figures and shades.
• Orient the references in the direction of the drawing view.
