USPTO patent drawing standards are set out in 37 CFR 1.84 and explained in the MPEP. Review the rules for the application type, prepare a clear disclosure and check the final filing export for reproducibility. This checklist highlights common format and review questions.

37 CFR 1.84: Patent Drawing Checklist

Application of color

Black-and-white drawings normally use clear, solid black lines. Digital preparation is common; the filed result must meet the relevant reproduction and format requirements. Color submissions have application-specific requirements. Check the official utility or design guide rather than assuming the same procedure applies to both.

Use of Photographs

Photographs are only permitted where photographs are the sole practical means of demonstrating the invention. For instance, inventions comprising a scientific gel are not suitable for drawings, and photographs are more suited to reveal the invention.

Scale of drawing

The size of the paper should be either 21cm by 29.7cm or 21.6cm by 27.9 cm (8 1/2 by 11 inches). The drawing should be represented on a scale that will not be crowded when reproduced at 2/3 size. Hints like “full scale” or “1/2 scale” are not admissible since they lose their significance with reproduction in various setups.

Margins

Use the correct sheet size and keep figures within its usable area. A4 and U.S. letter have different usable dimensions; do not apply an A4 drawing-area limit to every sheet. Minimum drawing-sheet margins are:

•  top: 2.5 cm
•  left side: 2.5 cm
•  right side: 1.5 cm
•  bottom: 1.0 cm

Requirement of paper

The paper must be white, matte (non-shiny), flexible and solid. One side should contain texts while another side should be left blank.

Regarding Views

The drawing must carry as many views as essential to precisely exhibit the invention. Exploded views and blown-up partial views of specific portions of the invention may be utilized. The drawings should be assorted collectively and meet the same direction on the page if you require to display different views of the invention. Drawings are favored to be in the upright form (as opposed to the horizontal landscape drawings). Shading is reinforced where it assists in explaining the invention.

Rules Regarding Numbers & Letters 

Numbers are preferred to letters as relating attributes in a drawing. The English alphabet must be applied when using letters. All numbers, letters, and reference lines, emerging on the drawings, shall be easy and definite. Brackets, circles or inverted commas shall not be practiced in connection with numbers and letters. 

What must be incorporated?

Patent drawing should cover invention name, inventors’ name, application number, and identification. These are obliged to be inserted to produce a successful patent drawing.

Words in Drawings

 The drawings shall not hold text matter, except a single word or words, when completely requisite, such as “water,” “steam,” “open,” “closed,” “section on AB,” and, in the event of electric circuits and block schematic or flow sheet diagrams, a few short catchphrases necessary for understanding. Any words adopted shall be so placed that, if translated, they may be passed over without opposing any lines of the drawings.

Bottom Line

Patent filers should not underestimate the significance of drawings in their applications. Patent offices implement explicit standards related to the technical aspects of drawings they receive, but consideration must be given to more than just satisfying those specifications. A patent applicant’s most reliable choice is to employ the services of a professional draftsperson specialized in technical patent drawings and aware of the various needs of patent offices.

Official MPEP Drawing Sources

Consult MPEP 608.02 and 37 CFR 1.84 for drawing standards and MPEP 507 for drawing review. Use the utility guide or design guide for the intended application.

Final Drawing Review

Reconcile the figure set with the approved disclosure, check shared features across views and inspect the actual exported pages. Record source version, reviewer and unresolved questions. Review view selection and design drawing margins, or contact Menteso to discuss a drawing brief and quality checks.

There are several jobs that require no experience and practice and can be accomplished by anyone while there are some tasks that need enormous training and detailed knowledge to perform. Patent drafting is one such job that demands years of experience and qualification. Not everyone can complete this task on their own. One who aspires to defend their invention or unique ideas should consult patent professionals for every step in order to get their invention patented successfully.

Patent drafting basically involves preparing a patent application which has all the detailed stipulations about the invention. It should be made accurately and precisely in order to avoid the chance of getting it rejected by the court.

Here are a few things that a patent application comprises

• An abstract of the patent
• One or more claims
• Background data
• Drawing and detailed description
• Summary

Why does one require patent drafting services?

The patent drafting service is a process of building claims and patent descriptions. They act as a foundation for every patent application and explain the invention accurately and briefly. Although patent drafting services are a tedious and lengthy task, the risk of getting applications rejected diminishes. Following are few points stating the requirement of patent drafting services:

• No malformed application: Patent drafting is a fundamental and critical step. It can be done by an unprofessional as well but the probability of the approval of application and claims holds fewer chances as the tiniest mistake can make your application at fault. As per USPTO, only 20% of the issued patent applications were commercialized. This declares the need of hiring patent drafting professionals for patent drafts.
• Precisely defined claims:  Seeking the guidance of patent drafting services is an exceptional assistant to inventors as it accommodates them to define and express their invention in a detailed manner and remove all passive voices. They use the correct expressions to manifest the ideas with less complication and make them perfect for approval by the jury.
• Limited chance of patent rejection: A poorly written draft may bother or annoy the judges which can end up in patent rejection. To avoid such scenarios, taking the cooperation of professionals will be a wise and right choice.
• Cost-effective:  An inadequately drafted application may attract litigations to amend the claim and language to receive undesired gains. This can be a high-priced error. Selecting an expert is less costly than this. It may seem to the applicant that taking the help of professionals is expensive but they are unaware of the benefits that they will reap in the future.
• Complicated nature of drafting: It may appear an easy business to compose a patent application but it is not a piece of cake for everyone. The nature of the application is way more intricate than it seems. A professional with years of technical and legal knowledge can draft a patent application explicitly. Moreover, the contents of the application should be represented well. For instance, the scope of the patent, etc. wants a thorough explanation which only a professional can handle well.
• Valuable advice: Patent drafting services not only include drafting a patent application but also incorporate valuable and relevant advice that helps you get your invention patented rightly. Patent drafting is a prolonged and tiresome job and filled with a complex process that becomes difficult to understand by a normal person.
• Competitive edge: Patent drafting services give the inventor a competitive edge. A broadly or narrowed established claim can allow the competitors to circumvent the patent. A professional drafter keeps this important point while drafting a patent application and prevents your competitor’s circumvention.

Top 5 things to contemplate while picking a patent drafting service provider

1.  Qualified Patent attorney: Before engaging an attorney for patent drafting service, make sure the attorney holds the required qualifications and is listed to practice before USPTO. He/She also possesses technical and scientific knowledge and must have passed the examination conducted by USPTO to practice in the patent.
2. Consider the cost arrangements: Patent drafting services are expensive and one should only engage with a firm or service provider after knowing the total cost involved in drafting a service. There are times when the service provider discusses the cost after analysing the technicalities of the invention.
3. Look for options: There are many attorneys who will help you get your inventions patented. But people hesitate to reach a number of attorneys fearing the bill. A firm cannot send you a billing email unless you have signed an engagement letter with them stating about bills. Consequently, you should go out and look for as many choices as you can so that you can select the best out of all for your invention.
4. Choose an attorney who can understand your invention: A patent drafter should have both legal and technical knowledge. It is imperative that the attorney understand your invention or idea properly and draft it well in the application. Missing to do so can result in refusal. Hence, obtain the one who has satisfactory expertise in the area of your invention along with legal understanding.
5. Relationship of the firm with the USPTO: Many times, the speed and examination of the patent application can be improved if the firm is having a direct connection with the USPTO examiner interviewer. In case, the application gets rejected, interviewing with the examiner for the same can pave a way to improve the application and hence helps in rectifying it for the approval in future.

A patent draftsman helps turn invention information into a clear technical disclosure or drawing set. The term can refer to different work, so confirm whether the engagement covers patent illustration, specification preparation, claims or another task. The title alone does not establish authority to provide legal advice or represent an applicant.

Explain a Patent: Application vs. Granted Rights

A patent application is a request for protection submitted to the relevant patent office. A granted patent provides rights defined by the applicable law and issued claims; filing an application alone does not guarantee a grant or prevent every competing activity. Patentability, scope and enforceability require separate assessment.

A utility application addresses functional subject matter, while a design application concerns ornamental appearance. Read the USPTO application guidance to understand the different routes before choosing a preparation brief.

What Does a Patent Draftsman Need From the Inventor?

Collect a technical explanation of the problem, proposed solution, components or steps and how they interact. Supply drawings, photographs, CAD files, test information and relevant variants where available. Identify uncertain facts and known prior art so the drafting team can ask focused questions.

Specification Preparation and Claim Support

The written disclosure should explain the invention clearly and support the subject matter later claimed. Keep terminology consistent and map important features to relevant passages and figures. A concise title, appropriate background and summary, detailed description, claims and abstract each serve different purposes; they are not interchangeable.

Review the USPTO utility filing guide for the relevant sections. Do not apply an invented minimum word count to the title or assume that a marketing description establishes adequate disclosure.

Patent Illustration and Document Coordination

For illustration work, agree on the required views, reference characters, source version and review responsibilities. Compare each figure with the written description. The drafter should escalate missing information instead of inventing structure or selecting claim scope without instructions.

Review Before Filing

Have the appropriate practitioner assess disclosure sufficiency, claim wording, inventorship and filing strategy. Check consistency across names, terminology, figures and administrative papers. Preserve approved files and revision notes. Careful preparation supports review but cannot promise allowance.

Explore our claim drafting guide and patent drawing services. Contact Menteso with your source material, required deliverables, intended office and timeline to discuss a defined preparation scope.

To prepare drawings for a design patent, start with the appearance of the article you intend to claim, then develop consistent views for professional review. A drawing alone does not obtain a patent. The drawings form part of an application whose subject matter and disclosure must satisfy the applicable requirements.

How to Patent a Drawing: Start With the Right Question

A U.S. design patent concerns a new, original and ornamental design for an article of manufacture. A utility patent concerns a functional invention. A sketch may communicate either kind of subject matter, but simply creating or uploading a drawing does not establish patent rights. Discuss the intended protection before commissioning final figures.

Build a Clear Drawing Brief

Provide the article name, source photographs or CAD files, relevant variants and a description of the appearance to be shown. Identify unresolved design changes. Have the responsible practitioner confirm claimed and unclaimed subject matter rather than leaving those decisions to assumptions during illustration.

Use a consistent source version for every view. Record the approved brief and revision history so that the drafter, inventor and reviewer can reconcile later changes. Consider filing strategy and public-disclosure timing early rather than assuming preparation should always wait until product launch.

Choose and Reconcile the Views

Plan perspective and appropriate front, rear, side, top and bottom views sufficient to disclose the design. Check whether any omission needs an explanation. Compare shared edges, contours, proportions and surface details across the set. Do not combine conflicting product versions.

Check Lines, Shading and Page Format

Prepare legible line work, appropriate surface shading and consistent figure descriptions. Review broken-line treatment for unclaimed subject matter. Follow the USPTO design patent application guide, including any special requirements for photographs or color material.

Check the exported filing document for sheet size, margins, clipping, numbering and reproduction quality. Our design drawing requirements guide provides the drawing-sheet margin checklist.

Review the Complete Application

Drawings must work with the claim, title and figure descriptions. Ask the responsible practitioner to resolve ambiguous disclosure before filing. After submission, monitor official correspondence and the deadlines stated in each notice; do not assume that a visual correction can add missing subject matter.

Explore Menteso patent drawing services and our application guide. Contact the team with the article, available source files, intended office and timeline to discuss a drawing brief.

Patent drawings explain an invention or product visually. In a U.S. design patent application, they disclose the ornamental appearance claimed for an article. A useful drawing set combines sufficient views, consistent details and clear treatment of claimed and unclaimed features.

This guide focuses on design patent drawings. If you need illustration support, explore Menteso’s design patent drawing services or discuss a design patent application.

Design patent drawings vs. utility patent drawings

A design application addresses appearance; a utility application addresses an invention’s functional subject matter. The drawing brief should identify the intended application type before illustration begins. Read our utility vs. design patent drawings guide for the distinction.

Which views should design patent drawings include?

The USPTO design patent application guide calls for enough views to disclose the claimed appearance completely. Front, rear, top, bottom and side views are common. Perspective views can help show three-dimensional shape. A view may sometimes be omitted with an appropriate explanation, such as an identical or mirror-image side.

Prepare a view list before drawing. For each figure, record its direction, the features it must show and any proposed omission for professional review. Check that curves, openings and proportions agree across the complete set.

Solid lines, broken lines and surface shading

Solid and broken lines communicate different aspects of the claimed design. Broken lines can identify unclaimed environment or boundaries, with their purpose explained in the application. Surface shading helps disclose contours. The appropriate treatment depends on the design; consult MPEP section 1503 rather than treating every dotted or shaded area as interchangeable.

When sending a brief to an illustrator, separate visual instructions from decisions about claim scope. Ask the responsible patent professional to approve what is claimed, what is excluded and how the drawings and descriptions express those decisions.

Patent drawing preparation checklist

• Gather clear photographs, sketches or CAD views of the same product version.
• Identify the intended filing jurisdiction and application type.
• Agree the figure list and flag hidden, repeated or omitted views.
• Check consistency of edges, surface features and proportions between figures.
• Review line treatment, shading and figure descriptions together.
• Keep an approved final set and a record of revisions for the filing team.

Common mistakes to catch before filing

Look for mixed product versions, mismatched views, unclear surfaces and unexplained broken lines. A polished marketing render is not automatically a suitable patent drawing. Have the final illustrations reviewed as part of the application package, rather than as isolated images.

Avoid assuming that missing detail can always be added after filing. Resolve disclosure questions before submission with the professional responsible for the application.

Frequently asked questions

Do I always need exactly six views?

No fixed view count replaces complete disclosure. The required set depends on the article and claimed appearance. Review proposed omissions and explanations against the USPTO guide.

Can I use photographs instead of drawings?

Photographs are permitted only under applicable requirements. Check the USPTO guide and obtain application-specific advice before relying on product photos.

What should I send for a drawing quote?

Describe the article, available source files, expected views, filing jurisdiction and review deadline. Start with a general description and agree a suitable method for exchanging detailed invention materials.

Patent illustrations are important and play a crucial role in the patent application. But unfortunately, most of the patent applications get rejected in the initial stage, then there are certainly other issues, including default in drawings, which is the most ignored part of the patent application.

The patent application is also interfered with without having the formal drawings and the purpose of adding drawing in the patent application is to create a visual appearance of the innovation because a description of the innovation alone cannot create an actual comprehension. The illustrations can be regarded as a secondary language that assists the potential and the society to get the actual picture of the innovation.

How Patent Illustration/Drawings got Rejected and How to Get Rid of Them

Let’s consider specific points due to which this patent got rejected: 

1. Do not admit to direct reproduction

Patent drawings should not be filed directly to the office. There should be proper black and white line drawings, which is highly preferable by almost all of the judiciaries who can use color or grayscale pictures too, for some specific patents only. For that, it is going to take more effort, time, expense, and expertise.

2. Drawing contains unnecessary text matter

Another rejection point, which says, the sheet or the drawing contains unnecessary text matter. This is when the patent gets rejected due to the carefree and non-professional approach of the applicant and ends up having an office action. The patent drawings should not have any text or number that is not needed or belong to the patent drawing and this is why you need a patent drafter who understands the draft and patent prerequisite.

3. Lines with persistent black color

The drawing should have lines with persistent black color that should be uniformly thick to be long lasting and withstand the pressure handling in several copies. It is a tedious task and it depends on the expertise of the illustrator who makes it precise to the requirement.

4. The cross-section

When an inventor dissemble its product, it divides into several sub-parts with their section surfaces. These surfaces need to be shown with a hatch filing into it where various hatch patents can be used to indicate various surfaces. It is necessary to have a patent expert who has this knowledge of hatch patents and how he or she differentiates among the surfaces and the material of different parts of patent drawings.

5. Non-distinguishable drawings while reproducing

This is a most important point of an objection among drawings and it keeps cropping in an office action many a time, especially in patent illustrations that have complexes in minor details. In this situation, while filing a patent, the drawings are reduced to size two-thirds in reproduction, indications, such as actual size or scale 1*2 are not allowed on the patent drawings since it will lose their meaning when reproduced in another format.

6. Difficult to differentiate claimed and unclean portions

In most of the design cases, it makes it difficult to differentiate between the claimed and unclean portions, this causes a to and fro rejection of the patent. A patent illustrator is proficient enough in preparing those patent drawings with fineness, without compromising with quality and claim of the patent product.

Another point that we used to see a lot in an office action form, that is, it contains numbers and letters, less than 0.32 cm. 

7. Maintain a constant size

Although, it seems much easier to maintain a constant size of the text. But this is among the most rapid reasons to receive rejection as it is essential to know which text to be kept and which not. Sometimes, the section including the text is too small or too large that it becomes very difficult to go by the standards. For getting it approved you will need the assistance of an expert in drawings.

Sometimes a figure is hard to keep on a single sheet. It occurs mostly in flow diagrams, piping and instrumentation diagrams, electrical circuits, and many more. To make them ready for filing, one must know how they can be split into different sheets by drawing connections among the parts of figures that can be seen as a single figure when assembled.

8. Figures are not properly arranged and separated clearly

Another objection coin contains figures which are not properly arranged and separated clearly. This becomes a problem when you try to keep multiple figures into one sheet, it makes the patent drawing messy and difficult to recognize the actual claims or essential details while reducing prediction.

9. Drawings not arranged in an upright position

It is said that the drawings are not arranged in upright positions, clearly separated from one another. In patent drafts, the figures are used to keep an upright position whether they are in cock-trait sheet or a landscape sheet. Orientation of the sheet can also lead a patent application towards rejection. These were the points that can cause a patent rejection and these were some of the common requirements that can be considered by most of the countries.

10. Satisfactory Reproduction

Satisfactory Reproduction guarantees that this patent is fit enough to be filed as per the PCT guidelines, it depends on the rule number 11 and 26 of the PCT system. These rules and points can be different for different countries, or maybe, they have similar rules, but with a different approach or different rule numbers. 

Conclusion

According to the patent laws, an applicant must furnish a patent illustrations of the invention wherever applicable. Innovation is always properly explained when the description is supplemented with a detailed illustration. The illustrator should draft illustrations keeping in mind the patent drawing rules of the concerned PTOs to avoid patent drawing rejections. This includes utility patent drawings and design patent drawings that can represent the invention in detail.

Patent illustrations or drawings are one of the most essential components of a patent draft. If made prudently and wisely, it can assist you a lot in expediting the overall patent granting process. Unlike other kinds of normal drawings, making drawings for patents demands understanding of patent drawing rules, acquaintance with the patent regulatory framework, and an artistic approach towards drawing.

What are illustrations for patents?

Patent illustrations are also called patent drawings and are used to represent an innovation visually. In this, we can use graphs, diagrams, pictures, and drawings to present our innovation visually.

Are illustrations for patents mandatory?

No, patent illustrations are not mandatory as per statutory rules; still, a candidate should include patent drawing as it adds a lot to the comprehension of the innovation. It allows a quick look at the final product which will be available after it is manufactured.

What are different views needed in a patent drawing?

There are mainly six views that are utilized in patent illustrations. Though there are no minimum views required, still, we need to add maximum views as possible as it can assist patent examiners to comprehend the innovation without emphasizing much on their eyebrows. Some of the essential views those we can use in patent illustrations are:

• Sectional views
• Duplicate views
• Exploded views
• Plain and un-ornamented view
• Flat objects Views

What is dimensioning in patent illustration?

Dimensioning adds information that specifies

• The exact size of the object
• Location of features (e.g. holes)
• Characteristics of features (e.g. depth and diameter of hole)
• What materials are to be used, how the part is to be completed
• Dimensions also communicate the tolerance (or accuracy)

Comprehending the patent illustrator’s preliminary steps, in anticipation of good patent illustrations, is essential to your success. Great patent illustrators focus on this, constantly.

The final form of a patent application is of great significance. The USPTO places great emphasis on thoroughness. There are numerous rules to be complied with. Every patent examiner has tremendous discretion over whether a patent application is approved or rejected. By completely meeting the prerequisites and guidelines of the USPTO’s, you will have a better application. Your possibility of success is better than an application that does not comply. It is imperative to focus on detail. 

Here are steps to prepare your information for patent drawings: 

1. This is the time to collect all of your prior art references. These references can come from worldwide patent searches, textbooks, the Internet & more. Focus on what is different about innovation. Patent illustrators may also ask you, what parts require to be displayed in detail of your illustrations and what parts are general.

2. In a comprehensible form, to the most excellent of your ability, rough sketch the innovation. This is the basis of your whole patent application. The patent illustrations are the most essential element of the patent application. Ask yourself, when an examiner looks at your patent application, what is the first thing to be looked at? and that is the drawings.

In sketching your preliminary drawings, you do not have to be worried about the size of the drawings or the layout of the figures. The patent illustrator will deal with that. The primary concern is to show all aspects of your innovation.

3. Note down a name adjacent to each part, in each sketch. 

4. Draw a lead line connecting the name to the part or component. 

5. Show every new feature. You do not have to be so worried about labeling the prior art.

6. Construct a description of the innovation in short simple sentences from your sketches.

7. This information alongside some other collateral material, like photographs, is all that patent illustrators require to finish formal patent illustrations. Patent drawings are the basis of a patent application. Good patent drawings or illustrations by professional patent illustrators guarantee a successful examination by the USPTO’s examiner.

The essential task of completing a patent application, also known as a patent specification, is assisted by patent drafting services for inventors. A patent is a type of intellectual property that you can utilize yourself, sell or rent (license) to others. It is allowed by a government and you have to implement it yourself. There are three main components to a patent: 

1) a full description of your invention; 

2) drawings; 

3) claims. The claims represent the things about your innovation that are unique, they detail the particulars that others can’t duplicate without your authorization.

Patent Preparation additionally known as Patent Drafting is the initial phase in the process of obtaining a patent. It is the method of writing the patent description and claims. At the point when the patent is given, the draft is the specification part of the document. Patent drafting contains different aspects like the total knowledge of the innovation, technical subject matter, in-depth knowledge of many laws, a detailed description of the innovation, and associated patent drawings therefore it is a tough task.

Patent drafting services provide inventors with assistance in the important step of completing a patent application, sometimes referred to as a patent specification. There are two distinct kinds of patent applications utilized for the patent process: complete and provisional specification.

Patent Drafting

Patent drafting is the method taken when creating a patent application. Creating a patent specification that is of high quality, notwithstanding if it is finished or provisional, is most significant. A patent application will normally incorporate the accompanying:

1. An abstract of the patent

2. One or more claims

3. Background information

4. Drawing and detailed description

5. Summary.

Provisional applications are utilized when the innovator has essential ideas for the innovation he or she wants to patent but at the same time feels there is an opportunity to get better. A provisional application gives the innovator a priority date. Claims do not need to be incorporated for provisional applications.

Claims, a very significant element of the patent application, determine the scope of protection being sought with the patent application. They also outline what other innovators cannot do to prevent infringement liability. Claims are necessary during both prosecution and litigation.

Whenever you have filed a provisional application, you have 12 months or a year to finish and submit a specification that includes claims. A whole patent application must be within the boundaries established by your provisional application and provide a comprehensive description of the innovation, including the best way of performing the innovation.

Importance of Patent Drafting

A company’s innovations and ideas are key elements to its future success and growth. These significant assets need to be recognized, nurtured, and protected so their importance can be realized.

Most innovators feel the best at explaining their innovation, and while they are normally ready to clarify the utilization of the innovation, more technical language can prove to be troublesome. 

A patent draft should describe in complete detail how to enable the invention, or how a person ordinarily skilled in that art could make and use the said invention. The innovation also has to be notably distinct from prior art both in structure and function. Engaging a patent professional for patent drafting is very significant because of the detailed technical component and finding the right balance between broad and narrow claims.

The correctness and completeness of a patent application and stated claims become vital if and when prosecution or litigation happens. Using the patent drafting services of a patent professional who comprehends patentability requirements and underlying technology may end up saving you time and money in the long run.

While claims are not required in a provisional application, they are needed for the whole application. Describing and claiming the best method appropriately will help prevent others from simply “designing around” the innovation. Drawings are also often a helpful and sometimes necessary part of both provisional and complete applications.

Patent Application Drafting Workflow

The innovator will submit an Invention Disclosure Form (IDF) that includes a summary of the innovation to a patent professional. Whenever this is done, the accompanying advances will be taken:

1. Consultation between innovator and patent professional to ensure a complete understanding of the invention. 

2. Identify needed invention parts and verify with the inventor.

3. Claim drafting done in multiple stages.

4. Prepare basic claims.

5. Inventor reviews.

6. Incorporate inventor notes into the next stages of preparation.

7. After reviews are complete, prepare the final claim.

8. Specification drafting: Once the innovator and patent professional agree on the innovation scope, the patent professional will draft the specification and appropriate claim set. This will include a whole explanation of the technical points, highlighting any particular points that make the innovation unique.

9. Enable claims.

10. Incorporate any illustrations and embodiments.

11. Once the draft is finished, it will go through several reviews.

12. Have an attorney complete a review if your jurisdiction requires this.

13. Draft will be sent to the inventor.

14. Any comments or edits received from the client are incorporated.

15. Completion of the final draft.

Patent drafting is the process of writing a patent specification that clearly and sufficiently describes an innovation. It is a very significant step in the process of patent filing.

The possibility of getting a patent grant relies largely on the quality of drafting of the patent specification.

A complete patent application includes numerous sections that form part of a patent specification. The Patent Office defines these sections and includes the Title of the invention, the Field of the invention, and the Background of the innovation. They also include a summary of the invention, a brief description of the drawings, a detailed description of the embodiments and Claims.

Patent Drafting Mistakes

A patent specification is a techno-legal document. Through this document, innovation and the scope of protection of the invention are identified. 

Check out some of the common mistakes that can occur while drafting patent specifications:

1. Insufficiently describing the innovation:

 Lack of disclosure of sufficient data in the patent specification is one of the common mistakes. This happens when the specification is drafted by an inventor himself or by an inexperienced patent agent. Likewise, this occurs because of the assumption that the person reading the patent application will comprehend the innovation properly with the provided details. The patent law requires a candidate to provide an easily understandable description. 

2. Claiming the innovation too broadly:

This is another mistake that a rookie in patent drafting performs. For the sake of broadening the scope of protection of their innovation, most of the innovators try to claim their innovation too broadly. They usually do this to cover as much protection as possible from their patent application. However, claiming an innovation too broadly can make the scope of protection of the innovation indefinite. 

3. Claiming the innovation too specifically:

For an innovator, the method of performing their innovation is always very clear. Due to this, it becomes rather hard for the innovator to think about a broader version or an alternate embodiment of their innovation. 

4. Utilizing inconsistent terms:

One of the necessities for writing a very much drafted patent specification is the utilization of consistent terms. Claims containing inconsistent terms can cause unintended results in patent litigation.

5. Drafting claims without adhering to the drafting rule:.

Patent claims are written under certain rules. Patent Offices define these rules and are essential to follow for properly drafting the claims. Failure to draft the claims following these rules raises the ground for rejection.

Some of the rules include:

• The patent claim should be written in a single sentence.
• The claim should include a preamble, a transitional phrase, and a body.
• Each “new” component ought to be presented utilizing ‘a’ or ‘an’ for the first time and then utilizing ‘the’ or ‘said’ during subsequent usage.

6. Prioritizing ‘How’ before ‘What’ and ‘Why’: 

The biggest mistake that patent drafters often make is to portray the functionalities of the invention before making the basics of the invention. They invest most of their time in clarifying ‘How the invention works?’ rather than describing ‘What the invention is?’ and ‘Why it is created or what’s the purpose?’. It is essential to make the readers first aware of the innovation and then about its functionalities and operations. This will facilitate a better and clear comprehension of the innovation.

7. Framing ‘Actionable Information’ without comprehension ‘Legal Requirements’: 

This is also a very common mistake that happens when patent drafters tend to frame functionalities without the full knowledge about what and how much is legal to describe. Mistakes happen when the description of your innovation matches with the description of someone else’s application (filed earlier), unintentionally, maybe because both innovations fall under the same technology domain, structure, etc. It’s an absolute necessity to frame intelligently so as not to infringe any patent application which was filed before. 

8. Framing it ‘All with Specificity’ without focusing on avoiding ‘Ambiguity’: 

Describing functionalities with specific details is beneficial but it does not assure that the information is unambiguous. It is important to frame sentences in a manner that the reader can only get the idea of what the innovator meant to depict, not something other than that. It is necessary to check for ambiguity and then frame the sentences making it easier for the user to comprehend all its functionalities. 

9. Trying to depict ‘Specifications’ using ‘Generic’ terminologies: 

Sometimes, patent drafters try too hard to figure out ways to depict all specifications, while keeping it generalized at the same time. It is a good practice to portray functionalities in general terms to attract a large audience. But, expanding and explaining technicalities in a general way, sometimes changes the meaning which is intended by the innovator. 

10. Depicting details using ‘Common Abbreviations’: 

Mostly patent drafters try to depict more than one thing of the same type, using common abbreviations, such as ‘etc., or so on’. However, it’s wrong to depict things generally utilizing these, since it may or may not ask the reader to utilize his or her imagination to put anything in that place according to their understanding. It produces ambiguity and non-specificity to the presented information to have more than one literal meaning. It can be helpful if the readers are familiar with the terminology and jargon, which are intended by the innovator by the use of abbreviations. But, this sort of writing is not recommended as people unfamiliar with the dialects can interpret in a wrong way, which will eventually demolish the general purpose behind patent drafting.

Patent Illustration Services

A drawing/diagram is a vital factor in a patent application for a better comprehension of it by a common man. Patent law mandates the prerequisite for patent drawings in a patent application for precise illustrations, which makes it beneficial to convince the illustrator and expedite the entire process. It becomes unavoidable to have an illustration in a patent application, and these are normally referred to as a patent illustration, patent drawing, patent figures, and patent images, and more.

A good patent illustration can make it simple for the patent drafting, and thus speeding up the entire process, alongside the prosecution of the application. Patent illustration is equally important if not more than that of the drafting of the patent application, and for which it requires the same measure of expertise, skill, and diligence that a draft demands of a patent application.

Patent Illustrations are needed to be in the form of line drawings in black and white as against in the form of color etc. The Indian patent and design offices have rules to the impact of paper size, margins, the durability of the patent, etc. Likewise, the other jurisdictions have rules to the impact of what types of line drawings are allowed. Shading to what degree is allowed and not.

Indian patent Act and rules have particular rules about the patent Illustrations. The Indian Act and rules also allow for the patent drawing to be referenced as a part of the Abstract in the event the same is considered as important in the understanding of the technical invention, the advancement, and utility which is to be mentioned as a part of the Abstract. 

If it is not in the drawings? it is not in the patent

Yes, it is true beside the case of chemical compounds or composition. It has been seen that all the other fields of innovation have the ability to squeeze in a figure or two, which implies likely the patent examiner will wind up asking the candidate or the attorney to cough up number of diagrams to empower the crystal clear projection of the innovation.
