Patents might not win awards for gripping storytelling, but developing a strong patent style can make the process smoother, your applications more effective, and your clients’ inventions better protected.
Read on as we explore the key elements of a strong patent drafting style, explain why they matter, and show how you can elevate your drafting process to the next level.
What is a patent drafting style?
A patent drafting style is the unique way you organize and present information in your patent applications. It’s not just about what words you choose but how you organize them to ensure that your application flows logically and meets legal requirements.
Take a look at these examples. Which one do you think works better?
Example A: “There is provided an apparatus comprising a housing within which are disposed a motor and a plurality of sensors, wherein the motor is operable to rotate a shaft.”
Example B: “An apparatus includes a housing containing a motor and a plurality of sensors. The motor is configured to rotate a shaft.”
If you think Example B has a stronger patent drafting style, you’re right! Here’s why:
It’s shorter and avoids unnecessary filler phrases like “there is provided.”
The subject (“an apparatus”) is clear and immediately sets up what’s being described.
Each idea flows naturally — first the housing, then its contents, then the function of the motor.
This is the essence of a strong patent drafting style: clear language, logical structure, and consistent phrasing.
Key components of a patent drafting style
A strong style boils down to a few key elements that keep everything clear, consistent, and easy to follow. Let’s break it down:
Lexicon: The specific vocabulary used throughout a patent application. This includes terms like “embodiment,” “variation,” or “plurality” and ensures consistency in how the invention is described. A clear lexicon avoids ambiguity and makes the document easier to read.
Sentence structure: How individual sentences are written to describe the invention’s components, processes, and relationships.
Paragraph structure: The organization of paragraphs to describe specific features or steps of the invention. Each paragraph should focus on one concept, creating a logical flow that’s easy for examiners and other readers to navigate.
The importance of a strong patent drafting style
Whether you’re new to patent drafting or looking to up your game, developing a consistent patent drafting style pays off in more ways than one. Here’s why it matters:
Clarity for examiners: A well-drafted application helps patent examiners quickly grasp the invention’s core idea, reducing misunderstandings and speeding up prosecution.
Stronger claims: Clear, consistent descriptions make it easier to import language directly into the claims, ensuring §112 support for any amendments you make during prosecution. This gives you greater flexibility to adapt your claims as needed throughout the process.
Efficiency: Clear and consistent descriptions streamline the drafting process, reduce time spent rewriting, and make future revisions faster and more straightforward.
Professionalism: A polished application reflects well on the entire team, showing clients — and their stakeholders, investors, and business partners — that their invention is in expert hands.
6 Tips for Developing a Strong Patent Drafting Style
Understand what makes the invention important
A strong patent drafting style begins with a clear understanding of the invention’s significance and how it differs from the prior art. While some jargon is necessary for patent applications, overusing it can obscure the core innovation, making it harder for patent examiners to grasp the value of the invention. This can delay allowances or lead to unnecessary rejections.
To avoid this, use the summary section or create a separate dedicated section that communicates the invention’s importance in plain, accessible language. Think of this as the “elevator pitch” for your patent — use this space to answer two key questions: What problems does the invention solve? How does it improve on existing solutions?
By starting with clarity and saving the technical and legal details for later sections, the rest of the application can be built logically on a strong foundation. Your examiner will also have a clear framework with which to review the rest of the application, setting the stage for smoother prosecutions.
Choose a consistent drafting lexicon
Consistency in terminology is one of the hallmarks of a strong patent drafting style. Words like “embodiment,” “variation,” and “alternative” might have interchangeable definitions, but it’s important to choose what you want these words to mean for your applications and then apply them consistently. Inconsistency can confuse readers and even weaken your claims.
The same goes for plural vs. singular terms — decide upfront what phrase you’ll use to describe concepts like “one or more” and “more than one,” and stick with your choices.
By standardizing these terms, you’ll reduce ambiguity, streamline drafting, and ensure consistency throughout the application. Over time, this “patent lexicon” becomes second nature, preventing hours of writer’s block on future drafts. Plus, consistent terms make the application easier for the examiner to understand and harder for competitors to misinterpret.
Pro tip: Consider keeping a glossary of preferred terms to standardize your language across all applications.
Atomize your paragraphs for efficiency and precision
The structure of your paragraphs is more important than you might think. A good patent drafting style follows a predictable template, where each paragraph serves as a standalone explanation of a single aspect of the invention.
This strategy — atomizing paragraphs — does more than keep things tidy. It allows you to establish a rhythm in your drafting process, where every element is described using the same structure. This consistency reduces mental fatigue and speeds up your work.
Because each paragraph is a self-contained unit, it’s easier to edit the draft and ensure every part of the invention is comprehensively addressed. Plus, examiners and other readers benefit from this clarity when navigating your application.
Use consistent sentence patterns across descriptions
Consistency in sentence patterns makes the document easier to read and understand, especially for examiners who deal with hundreds of patents. For beginners, this means developing a habit of using repeatable structures when describing similar components or processes.
For example, if you’re describing several components, stick to a pattern like: “The [component name] is configured to [function] and is connected to [related component].” Use this same pattern throughout to describe other components.
Similarly, when detailing processes, start each sentence with the action: “Step A involves...,” “Step B follows by...,” and so on.
Focus on the subject of each sentence
A clear and deliberate choice of sentence subjects can make patent drafting significantly more effective. That’s because the subject often determines how easily your descriptions can transition into claims.
When sentence subjects are vague, passive, or unrelated to the invention, they create hurdles during prosecution. For instance, generic phrases like “it is shown” or “there is provided” don’t offer the clarity needed to tie your detailed description back to your claims.
Instead, focus on subjects like “the apparatus,” “the method,” or specific elements of the invention. This approach makes your application easier to parse.
Avoid passive voice
Here’s a rookie mistake that’s easy to fix: relying on passive voice. Passive sentences may sound formal, but they often lack the precision and clarity that patent applications demand. For beginner patent agents or engineers, mastering this small adjustment can make a world of difference.
Instead of saying, “The inclusion of the feature in the apparatus…” switch to “The apparatus includes...” Active voice puts the focus directly on the subject, which makes your writing more assertive and easier to follow. This is especially important when drafting sentences that might later become the foundation of your claims.
