A patent claim is undeniably an essential, if not the most crucial, part of a patent. It precisely explains what is claimed by the invention and what is to be protected. They are the only ones that define the exclusive rights granted to the patentee. Hence, making them the most significant part of a patent application. However, the language of patent claims can be hard to comprehend. As a practicing patent attorney for over 20 years, I see many inventors give up when they encounter the claim section. This blog aims to explain why the claims are written in a particular way and how claims should be construed. Read on if you are interested in dealing with this important part of patenting.
What is a Patent Claim?
Patent applications must clearly state the inventor’s invention to be granted exclusive rights. Apart from primary information such as the inventor’s name, filing data, and patent class found on the front page, a patent usually consists of the specification, drawings, and one or more patent claims.
Patent claims define the scope of protection granted by a patent. They specify the boundaries of what the patent holder has exclusive rights to make, use, and sell. The claims are the most important part of a patent because they determine what the patent covers and what it does not cover.
They are used to determine if a product or process infringes on the patent, and they form the basis for any legal action taken for patent infringement. Therefore, it is important to draft clear and concise claims that accurately reflect the invention and its scope of protection.
Patent claims are usually a description or a statement of technical facts that describe the invention. A patent claim is an integral part of a patent application. It defines the patent’s boundaries as well as the subject matter the patentee seek to protect.
It also clarifies what the invention covers and the scope. Patent specification is the “support” for the claims and describes the invention in detail.
essential characteristics to include in any patent claim:
- Complete: Claims must fully cover the invention.
- Specific: The claim language should be clear to allow others to understand what the patent covers.
- All claims should have support in the drawings and written descriptions.
WIPO defines a patent as a type of intellectual property that grants an inventor the exclusive right to an invention. In short, this can be, a new process, method, product or other intellectual property that gives an inventor exclusive rights to an invention. In addition, the public must be able to access technical information about the invention to obtain a patent. Next, we’ll discuss why patent claims are so important.
Understanding of Patent Claims
When you’re at the helm of a startup, every decision can feel like a major league game where each move could be a game changer. That’s exactly why understanding patent claims should be more than just a line item on your to-do list—it’s crucial armor in protecting your innovative ideas.
A patent claim, in its essence, is the part of your patent application that defines the boundaries of your invention’s territory. Think of it as the property line around your invention that tells others where they can’t tread without your permission. This is why crafting your patent claims with precision isn’t just important—it’s imperative for safeguarding your creation.
Imagine you’ve invented a new kind of smartwatch. Your patent claims must clearly delineate what about your smartwatch is proprietary and protected—whether it’s a unique way the watch monitors health metrics, or a novel method it uses to interact with other devices.
But here’s where it gets both interesting and a bit tricky: how you define these claims can be the difference between owning an ironclad protection or one that’s as leaky as a sieve.
Dive Deep into the Details
To start, dive deep into every component and capability of your invention. Avoid general terms and go for precision.
If your smartwatch uses a specific sensor layout that improves accuracy, your claim should detail this layout, not just mention ‘sensors’. This level of detail prevents competitors from sidestepping your patent simply by altering a minor, irrelevant feature.
Speak Their Language
When drafting your claims, use language that resonates with those in your field but keep it unambiguous to ensure it’s understood universally—not just by experts in your domain.
This means avoiding jargon that could be interpreted in multiple ways. For instance, instead of saying “high efficiency,” specify what makes it efficient. Is it battery life? Is it data processing speed? Clarity is your best friend here.
Scenario Sketching
Consider various scenarios in which your invention could be used. This doesn’t just help in expanding the scope of your patent but also in understanding potential areas where competitors might seek to infringe upon your rights.
Let’s say your smartwatch could have applications in healthcare, fitness, and home automation. Detailing these scenarios in your claims can broaden the protective reach of your patent.
Future-Proof Your Invention
The tech world moves at warp speed, and today’s innovations can quickly become tomorrow’s antiques. When drafting your patent claims, think about how your invention might evolve. Including potential future developments can protect not just the invention in its current form, but also its advanced iterations down the road.
Keep It Tight, But Not Too Tight
While it’s important to be comprehensive, adding unnecessary limitations can unduly narrow the scope of your protection. If there’s a core feature that makes your invention stand out, focus on protecting that feature without boxing it into specific embodiments unless absolutely necessary.
What Exactly is a Patent Claim?
A patent claim acts as the boundary of your intellectual property rights, defining exactly what you own and what you can legally protect against competitors. Think of it as a property deed for your invention.
It outlines the precise technical features that are covered under your patent, and by doing so, delineates where your territory begins and ends in the vast landscape of technological innovation.
Why Are Patent Claims So Crucial?
For startup founders, patent claims are not just legal formalities—they are the tools that protect the core innovations of your business. They provide a legal basis to stop competitors from copying, selling, or using your invention without permission.
A well-drafted patent claim can be the difference between thriving in a competitive market and watching someone else capitalize on your ideas.
Crafting a Patent Claim: More Art Than Science
The art of crafting a patent claim involves more than just technical knowledge; it requires strategic thinking and forward vision. When defining the scope of your patent claims, precision and foresight are key.
You need to be specific enough to protect your invention without leaving loopholes that competitors could exploit, yet broad enough to cover potential future applications and iterations of your technology.
Tailor Your Claims to Your Business Strategy
Your patent claims should align with your overall business goals and strategy. If your startup’s value proposition is based on a specific technology or process, your claims should robustly protect that area. If you’re planning to license your technology, broad claims can make your patents more valuable to potential licensees.
Engage with Professionals
While it’s tempting for budget-conscious startups to cut costs, drafting patent claims is not the place to skimp. Engaging with experienced patent attorneys who understand your technology can add immense value.
They can help craft claims that not only protect your current invention but also support your future business strategies and expansion.
Regular Review and Adaptation
The technological field can change rapidly, and what was relevant at the time of filing might need adjustments as new market competitors emerge, or as your own technology develops.
Regular reviews of your patent portfolio, with possible adjustments or additional filings, can keep your intellectual property rights aligned with your current business environment and future goals.
What are the importance of patent claims?
Incorrectly drafted patents could lead to invalidity as patent claims define the Patent’s protection. According to the Patents Act 1970, every complete specification must contain a patent claim which describes the invention for which it seek protection.
Properly written patent claims will ensure that your invention gets the protection it requires. Therefore, it is important to create the claims in the correct format. These are the reasons you should accurately write patent claims:
To Protect intellectual property
Well-written claims are the bottom-line of a good patent. These claims allow you to retain all rights to your inventions and designs. Moreover, you can use the rights to sue anyone who creates or sells your invention without your permission.
The technical description of the invention
Patent claims include the technical specification of the invention. Hence stating all the technicalities of the invention broadly is very crucial. In addition, one needs to shed light on other unknown technical aspects fields to which the invention relates.
Alternate uses of the invention
To accurately write patent claims is very important as it includes the alternate use of the invention. The most challenging thing for an inventor is to think of all the possible ways an invention can be used. It is important to state all the aspects which prove to be helpful in the future.
Problem-solving Description
Patent claims must include the solution to the problem the invention is trying solve so, writing might be a difficult task.
Patent prosecution can result in a rejection of an invention if the objectives are not clear. Hence, it becomes easier for the patent examiners to grant the patents if one clearly states the problem and the solution.
They Define Your Competitive Edge
At the heart of every startup is an idea that sets it apart from competitors. Patent claims crystallize this uniqueness by clearly outlining what your invention does and how it differs from others.
This delineation is what gives your product or process a competitive edge in the marketplace. Without strong, well-defined claims, you risk having broader overlaps with existing products, diluting your competitive advantage.
A Shield Against Infringement
Think of patent claims as your legal shield against potential infringers. They provide a clear boundary that others in your industry cannot cross without facing legal consequences.
This is particularly vital for startups that might find themselves up against larger, more established companies. A solid set of patent claims ensures that you can protect your niche in the market and go after any entity that tries to encroach upon your intellectual territory.
Facilitates Easier Navigation Through Patent Laws
The landscape of patent law is complex and can be a daunting maze for many. Clear and concise patent claims help in simplifying this navigation.
They serve as a reference point during legal scrutiny and patent enforcement, making it easier to ascertain whether a third party’s product or process infringes on your patent. Essentially, well-drafted claims can mean a smoother ride through legal challenges and patent disputes.
Enhances Your Valuation
For many startups, much of their valuation hinges on their intellectual property portfolio. Patent claims are a critical factor in this valuation. The stronger and more comprehensive your claims are, the higher the potential value of your patent.
This can be a game changer during funding rounds, mergers, or acquisitions. Investors often look at the robustness of a startup’s patent claims when assessing its worth and future potential.
Provides a Framework for Future Innovation
Patent claims do more than just protect current inventions—they also lay the groundwork for future innovations. By clearly stating what your patent covers, you also identify areas ripe for further development.
This can guide your research and development team’s efforts, helping them understand where they can innovate further without stepping outside the protected bounds.
Assists in Licensing Negotiations
If part of your business strategy involves licensing your technology, well-drafted patent claims are your best asset.
They make it easier to define the terms of licensing agreements, ensuring that all parties understand the scope of what’s being licensed. This clarity can prevent conflicts and misunderstandings, making licensing negotiations smoother and more productive.
Can you Ask for Additional Claims after patent Allowance?
Yes, it is possible to apply for new patents to extend the coverage of an allowed patent application, as long as you do this before the application matures into an issued patent. There are several ways to do this:
- Continuation Applications: A continuation application is a type of application that allows a patent holder to add new claims to a pending or issued patent. This can be useful for adding new coverage to a patent that is approaching expiration.
- Divisional Applications: A divisional application is a type of application that allows a patent holder to divide a pending or issued patent into two or more separate patents. This can be useful for creating new patents that cover different aspects of an invention.
- Continuation-in-part (CIP) Applications: A CIP application allows the patent holder to add new matter to a pending or issued patent while still claiming priority to the original application. This can be used to cover new and distinct aspects of an invention that were not previously claimed in the original patent.
- Reissue Applications: A reissue application is a type of application that allows a patent holder to correct errors or omissions in an issued patent. This can be used to correct errors in the claims or to add new claims that were not included in the original patent.
It’s important to note that these applications are subject to the same requirements of novelty and non-obviousness as the original patent and can be rejected for not satisfying those requirements.
Extending Protection with Continuation Applications
A continuation application is a valuable tool for inventors looking to extend the scope of their original patent. It allows you to pursue additional claims related to the same invention disclosed in your original application.
This is particularly useful if you’ve developed new aspects of your invention that you didn’t initially consider. Filing a continuation application can help keep your competitors at bay by covering these new developments under the umbrella of your original patent date.
Dividing Your Innovation: Divisional Applications
Sometimes, during the patent examination process, an examiner may require you to limit your claims due to issues like lack of clarity or overbreadth. In such cases, a divisional application can be filed.
This type of application lets you split your original application to protect additional inventions or embodiments that were disclosed but not claimed in the original. It’s a strategic way of ensuring that no potential aspect of your invention goes unprotected.
Adding New Matter with Continuation-in-Part (CIP) Applications
Continuation-in-Part (CIP) applications are particularly advantageous when your invention has been improved upon or modified after the filing of the original patent application. A CIP allows you to add new subject matter to the existing disclosure, which can extend the patent’s coverage to these improvements.
However, it’s important to note that the new matter added via a CIP application will have a different priority date from the original filing, which can affect the patentability of the new content.
Correcting and Enhancing Claims through Reissue Applications
Reissue applications are a remedy for inventors who may have claims that need correction for being too broad or too narrow, or for correcting errors that occurred during the patent prosecution process.
This type of application allows for the modification of the claims to better reflect the inventor’s contribution to the field and ensure that the patent protection accurately covers the intended scope of the invention.
Strategic Considerations for Additional Claims
When considering additional claims after patent allowance, it’s important to weigh the strategic benefits against the potential risks, such as increased scrutiny from the patent office or potential legal challenges to amended or new claims.
Additionally, each type of application carries its own cost and procedural requirements, which need careful consideration to ensure that the additional protection aligns with your business goals and patent strategy.
Navigating Post-Allowance Claims: Strategic Expansion of Your Patent
Once your patent application receives an allowance, it might seem like the finish line has been crossed. However, the innovation landscape is dynamic, and your initial patent might not encompass future technological iterations or uses that you envision after the allowance.
Adding claims post-allowance offers a strategic advantage by enhancing the protective canopy of your original patent. Here’s how you can approach this to ensure your invention remains robustly shielded in the market.
The Tactical Advantage of Post-Allowance Claims
Expanding your patent through additional claims after it has been allowed can seem daunting but offers a crucial edge in protecting and capitalizing on your intellectual assets.
It’s not just about safeguarding against potential infringements but also about enhancing your patent’s commercial potential through licensing or direct application in varied markets.
Continuation Applications: Broadening Your Innovation’s Reach
Think of a continuation application as a sequel to your original patent narrative—it extends the story by introducing new claims related to the disclosed invention without altering the initial disclosure.
This is particularly useful when you’ve uncovered more about your invention’s potential after filing the original application. A continuation must be filed while the original is still under consideration, providing a strategic pathway to extend coverage without starting from scratch.
Harnessing Divisional Applications to Capture More Terrain
When the patent office suggests narrowing your claims due to overlaps or clarity issues, a divisional application allows you to divide your original application.
This strategy is like planting flags in different parts of your innovative territory, ensuring that various aspects of your invention receive individual protection under their own merits. It’s a way to strategically segment your invention when different aspects of it can stand alone in utility.
Continuation-in-Part (CIP) Applications: Adding Fresh Innovations
If your invention has evolved or you’ve made enhancements since the original filing, a CIP application lets you add these new elements to your patent documentation.
This method is akin to updating your existing patent to reflect the evolved status of your technology, securing a more comprehensive safeguard that covers not just the original invention but also its improved versions.
Strategic Reissuing: Refining Your Patent Claims
Sometimes, the scope of a patent might either be too broad, risking invalidation, or too narrow, limiting its defensive utility. Reissue applications allow you to modify your patent post-grant to correct these scopes—ensuring that the claims precisely reflect your intended protective range. This can be crucial when you discover post-grant that your patent could be stronger or more targeted.
Engaging in Proactive Patent Management
Adding claims post-allowance should be seen as part of proactive patent management. It’s not just about defending what you’ve already created but about anticipating future developments, market expansions, and potential competitive movements.
By regularly reviewing your patent strategy in light of current market and technological trends, you can make informed decisions about when to expand your claims, reissue your patent, or file for a continuation or divisional applications.
Basic Types of Patent Claims
There are two types of patent claims; they describe inventions in patent applications. As a result, the terms describe the patent’s limitations and scope. According to 35 U.S.C. 112, claims can be classified into two types namely, independent and dependent claims.
Before filing an application for a patent, it is essential to understand all types of patents in order to determine the best type of patent for your invention. We will now discuss in detail the different types of claims in a patent application.
Independent Claims
According to the USPTO, these are claims independent of any other claims. They are the most comprehensive. These include a preamble as well as all necessary elements for the definition of the invention. So, independent claim sets the tone for patent protection in the invention. As a result, it protects patent infringement according to the doctrine of equivalents. This means that a patentee could be held responsible for infringing any limitation of a claim. If you are filing for a patent, it is important to understand the prior art claims.
Example:
1. A method of diagnostics using artificial intelligence, the method comprising:
acquiring a progressive scan of a patient using a multiple pulsed source in motion tomosynthesis imaging system;
performing image construction based on the progressive scan;
using artificial intelligence (AI) to detect a lesion by comparing a prior scan with the progressive
scan; and
determining with the AI a location of the lesion and lesion growth.
Dependent Claims
USPTO states that one or more claims can be presented in a dependent format, this allows referring to or further limiting another claim. Therefore, dependent claims can be based on an independent claim or previous claims made before them and therefore limit their scope of protection.
These are the most basic type of patent claims. Above all, claims must be carefully written to protect the invention against potential infringers to secure patent protection.
Example:
2. The method of claim 1, comprising generating a warning and sending one or more recommendations
to examine a region of X-ray interest (ROI) scan or CT scan.
3. The method of claim 1, comprising using AI to construct a model of the performance of each
subsystem in a normal operating mode and each of a plurality of different possible failure modes.
4. The method of claim 3, comprising:
dynamically predicting the performance of each subsystem based upon the response of each of the models to dynamically changing operating conditions.
For instance, the preamble to each claim begins with “A method as recited earlier in claim 1” of an independent claim. Dependent claims are related to the invention. In this instance, it is an apparatus.
Dependent claims do not necessarily cite back to independent claims; on the other hand, they can also cite a dependent claim. These dependent claims define and limit claim 1 (Independent Claims).
Independent Claims: The Foundation of Your Patent
Independent claims are the cornerstone of a patent application. These claims must be self-contained and describe the invention in its entirety without relying on any other claim of the patent.
They are designed to cover the broadest scope of your invention, setting the framework for what you are claiming as your intellectual property. When drafting independent claims, it is essential to strike a balance between breadth and specificity—broad enough to deter infringers yet specific enough to stand up against scrutiny for novelty and non-obviousness.
An effective independent claim will describe the invention in a way that encompasses all possible variations and uses, making it robust against competitive designs that try to circumvent your patent.
However, overly broad claims can be vulnerable to invalidation for lack of specificity or overlap with prior art. Therefore, careful drafting is crucial to ensure comprehensive but defensible coverage.
Dependent Claims: Refining and Strengthening Protection
Dependent claims build upon and refine the scope set by independent claims. They are used to narrow the focus and provide additional details or embodiments of the invention.
Each dependent claim refers back to an earlier claim, adding limitations or further specifying elements of the invention. These claims are crucial for defending against patent infringement by covering specific iterations of your invention that might be targeted by competitors.
Dependent claims enhance the enforceability of a patent by incrementally narrowing the scope of protection, which can be critical during litigation or patent prosecution. They help clarify and limit the invention’s scope and can be instrumental in overcoming prior art or obviousness rejections.
Furthermore, dependent claims provide a safety net; if the independent claim is invalidated, the dependent claims may still stand, providing residual protection for the invention.
Utilizing Multiple Dependent Claims for Layered Protection
Another strategic use of dependent claims is the drafting of multiple dependent claims, which depend on more than one claim. This method creates a web of protection that further complicates the efforts of potential infringers to design around your patent.
Multiple dependent claims can refer back to several other claims in a cascading or branching manner, thereby layering the protection and creating a robust barrier against infringement.
Specialized Claim Types: Means-Plus-Function Claims
Beyond the basic independent and dependent claims, there are specialized claim types like means-plus-function claims. These claims define a part of the invention in terms of the function it performs, rather than its physical structure.
Means-plus-function claiming can be advantageous for covering the underlying technology of software inventions or complex machinery where the function is crucial, but the specific hardware might evolve.
This type of claim must be carefully drafted to ensure that the function is described clearly enough to be understood by someone skilled in the art and is fully supported by the description in the patent specification.
However, the use of means-plus-function claims can be a double-edged sword, as their scope of protection is often limited to the corresponding structure, material, or acts described in the specification and equivalents thereof.
Strategic Application of Claim Types in Patent Drafting
The strategic use of different claim types in a patent application can significantly enhance the protection of your invention and provide a competitive edge in the marketplace.
By understanding the strengths and limitations of each claim type, inventors can tailor their patent applications to maximize coverage and enforceability, adapting to the unique demands of their technological sector and business objectives.
Patent Claim Construction: Tips
Firstly, there is no accustomed way to draft a patent claim. Each patent claim is unique and is dependent on the invention. The protection sought by the patent applicant will determine the process used.
However, the type of protection sought can determine whether the claim is narrower or wider in relation to the prior art. Patent claims should not be too broad, thus why it is essential to pay attention. They should not include anything that the applicant hasn’t invented. Or too narrow. As a result, the patent owner could lose their vital protection if this happens. To avoid such inconvenience, a patent attorney can be a good choice to assist you in writing your patent claims.
Three sections that make up a claim:
- The preamble
- The transitional phrase and
- The claim’s body
The Preamble
Preamble defines a category for the invention. It does not define the scope of the invention but rather it is the body of the claim that serves that function. The preamble clarifies whether an invention is a device or a technique.
Transitional Phrase
A transitional phrase follows the preamble. To clarify, there are three types of transitional phrases: consisting, consisting substantially of, and consisting. The “comprising”, the transitional phrase, is popular since it provides the most protection, . The U.S. trademark and patent office state that “consisting” is a transitional phrase that means the invention is restricted to the elements contained within it.
Claim Body
The claim body is everything that follows the transitional phrase. consequently, it explains the elements and limitations of the claim. The point of novelty should be the focus of the body of claims.
Secondly, each claim must start with a capital letter and end with a period. Except for abbreviations and periods, they cannot be used elsewhere in claims. To clarify, each claim can only contain one sentence. A line indentation can help you separate a claim that contains multiple elements or steps.
Indefinite claims are those that contain words or phrases with unclear meanings. To clarify, patent law requires that there be an antecedent basis. This requires that patent law claims to “specially claim the subject matter which the inventor considers the invention.” This is known as definiteness. So, claims are considered indefinite if they contain words or phrases with unclear meanings.
This is why every claim element must have an antecedent basis. Most importantly, an indefinite article, such as an, or a, should be used before a noun/noun sentence when first introduced. That is to say, if you use the noun later in the claim, it should precede the definite (e.g. the, or said). Here are some tips to aid you build your claims.
Use the right words in patent claims
Words should be very accurate in a manner while drafting the claims. The technical feature of your invention describes your invention and its variant parts. If you use a word that is new in the claims, make sure to clearly explain its meaning in your description. Pay attention to “relative words” such as slow, long, tall, high, wide, perfect, and so on, unless the claim contains a correlation.
Make sure the description backs up your claims
The claims have to be supported by the description. This means that all the characteristics of your invention that form part of the claims must be fully explained in the description. In addition, any terms you use in the claims must be either found in the description or clearly inferred from the description. That is use consistent terminology and words.
Claim alternative embodiments to the invention
Consequently, consider other embodiments of your invention. When writing a claim it is important to describe how the various components are structured and how the various components interact and connect. This broadens your protection.
Don’t limit yourself too much
Before filing claims, remove all limitations that are unnecessary. Do not file any limitations or technical features that aren’t necessary to cite the invention in its most patentable form. Pay attention to the prior art.
