Are you seeking patent protection for your invention? Do you have a patentable invention? Are you a patent applicant?  Have you received the first office action? Uncover the essentials of responding to USPTO Office Actions in this blog post about the patent process. Learn about the types, responses, and strategies to advance your patent application towards approval in the U.S. Patent and Trademark Office.


Embarking on the journey of patent registration begins with your application submission to the United States Patent and Trademark Office (USPTO). However, receiving a Patent Office Action from the examining attorney at the USPTO can be a pivotal moment in this process. This detailed guide aims to equip inventors and patent attorneys with the necessary insights to understand and effectively respond to Office Actions, paving the way for your invention’s successful patenting.

What is a Patent Office Action?

A Patent Office Action is a formal communication in the form of an official letter from the USPTO, highlighting issues within your patent application. This would be in a nonprovisional patent application, as only a utility patent application is reviewed for registraiton. Whether it’s a question of patentability or a compliance matter, understanding the nuances of these actions is crucial. Typically, it takes about eighteen months for the first review, where a Patent Examiner meticulously evaluates your application, focusing on the claims for patentability and formalities. A written response can be filed by the applicant, registered patent agents, or registered patent attorneys.  The office action is a part of the patent application prosecution process. A patent applicant will received a first non-final office action and if the legal issues with the patent application are not resolved, the applicant will receive a final office action.  This is all a part of the patent prosecution process.

Allowable claims in a patent application are those claims that have been deemed by a patent examiner to meet all the legal requirements for patentability. Allowable subject matter refers to the types of inventions that can legally be protected by patents. 

Types of Office Actions and Their Impact

Office Actions are categorized mainly into Non-Final and Final actions. Each type signifies different stages of your application’s review process, requiring distinct strategies for response. The distinction is critical for inventors to understand as it directly influences the course of action for amending and arguing against the rejections.

Strategic Responses to Office Actions

Responding to an Office Action is more art than science, involving a strategic mix of amendments and arguments. Key strategies include:

  • Interviews with Patent Examiners: A proactive discussion can clarify issues and potentially lead to an agreement without the need for formal responses.  You or your representative may need to conduct USPTO examiner interviews – yes, plural – in order to understand the legal problems with the pending claims.
  • Amending Claims: Tailoring your claims to overcome objections while maintaining the essence of your invention is a delicate balance to strike.
  • RCE (Request for Continued Examination): This option allows for further negotiation if initial responses do not result in approval.
  • Appeals and Continuations: When direct responses don’t suffice, appealing the Examiner’s decision or filing continuation applications might be the next steps.

Dealing with Specific Rejections

Office Actions may cite various reasons for rejection, including the most common reasons of novelty (§102), obviousness (§103), and non-patentable subject matter (§101). Each type of rejection requires a tailored response, often involving detailed arguments against the Examiner’s interpretations or amending claims to align more closely with USPTO standards.

Prior Art, Obviousness, and More

Navigating the complexities of patent application rejections by the USPTO can be daunting. This guide demystifies the reasons behind claim rejections and offers strategic insights for crafting effective responses. Whether you’re facing prior art challenges or dealing with non-patentable subject matter, understanding these hurdles is the first step toward overcoming them.

Prior Art Rejection of Claims Explained

Prior art rejections occur when a Patent Examiner identifies existing documents or publications that disclose the same features as your invention, predating your application’s filing. This can include anything from earlier patents to journal articles. The critical takeaway? Your invention must be novel and not previously disclosed to the public. Addressing these rejections typically involves arguing the novelty of your invention or amending claims to highlight unique aspects. 

Beyond Prior Art: Other Rejection of Claims

The USPTO doesn’t stop at prior art. Claims can be rejected for a variety of reasons, including but not limited to:

  • Non-compliance and Form Issues: If your claim describes something not detailed in your application or ventures into non-patentable subject matter (like abstract ideas), expect a rejection. Ensuring your claims are well-supported by your application and fall within patentable categories is crucial.
  • Obviousness Concerns: A claim may be deemed obvious if it combines known elements in a way that would be apparent to someone skilled in the field. This often involves a combination of references. Crafting a response might require demonstrating the non-obviousness of your invention’s combination of elements.
  • Anticipation by a Single Reference: This rejection signifies that a single prior publication describes all elements of your claim, rendering it unpatentable due to lack of novelty. Overcoming this requires a nuanced argument highlighting how your invention differs significantly from the cited reference.
  • Non-Patentable Subject Matter: Especially relevant for software patents or business methods, this rejection asserts that the claim covers abstract ideas or non-patentable concepts. Responses often involve redefining the invention to emphasize applicable technological implementations.

Section 35 U.S.C. 112 – Addressing Indefiniteness

Indefiniteness under Section 112 often stems from ambiguous claim language or unclear application drawings, potentially hindering the patent’s enforceability. This section mandates that patent claims must be precise enough to inform others of the boundaries of the invention. Pre-application review for clarity and detail can preempt such rejections. In instances where essential information is missing, strategic measures like filing a continuation-in-part application may resolve indefiniteness issues.

Section 35 U.S.C. 101 – Ensuring Patent-Eligible Subject Matter

Section 101 delineates the realm of patent-eligible inventions, excluding, for example, natural phenomena or abstract concepts. Challenges under this section, such as claims deemed to cover non-patentable subject matter, require nuanced negotiation with the patent examiner. This is especially true for inventions in the fields of biotechnology, pharmaceuticals, and software, where the lines of patent eligibility are finely drawn and frequently debated.

Section 35 U.S.C. 102 – Overcoming Anticipation by Prior Art

Anticipation rejections under Section 102 occur when a patent examiner identifies prior art that discloses all elements of a claimed invention. The key to overcoming this rejection lies in demonstrating that the cited prior art does not encompass every aspect of the claim or by amending claims to accentuate the novel elements of your invention. This direct approach requires a detailed comparison and a clear articulation of the invention’s unique features.

Section 35 U.S.C. 103 – Defending Against Obviousness

The most prevalent form of rejection, Section 103 addresses the non-obviousness requirement. An invention is considered obvious if someone skilled in the field could deduce it from public knowledge. Successfully countering a Section 103 rejection involves illustrating the innovative leap your invention makes over existing knowledge. This often requires a strategic dialogue about the combined teachings of cited references and may necessitate claim adjustments to underscore the invention’s novel aspects.

Navigating Double Patenting Issues

Double patenting rejections protect against extending patent protection unjustly by claiming overlapping inventions across multiple patents. Resolving these rejections might involve filing a Terminal Disclaimer to align the ownership and expiry terms of the overlapping patents or amending claims to distinguish them clearly from those in the earlier patent.

Addressing Claim Objections and Rejections

When dependent claims are objected to because of an independent claim’s rejection, your strategy might include amending the independent claim or arguing its patentability. Remember, each objection or rejection offers a chance to refine your claims for closer alignment with USPTO standards.

Crafting Strategic Responses

Your response to an Office Action should be tailored to the specific type of rejection or objection. This might involve legal arguments, amendments to clarify your claims, or both. Understanding the nature of the rejection—be it for prior art, obviousness, or other issues—is key to formulating a compelling reply.

What is a Notice of Allowance?

A Notice of Allowance is a document sent to a patent applicant from the USPTO after the patent examiner has decided to issue the requested patent. The Notice of Allowance comes after the inventor has turned in a patent application and provided all information about the invention. This information includes the patent’s description, design, drawings, or blueprints.

What is a Final Office Action?  

If the USPTO Patent Examiner finds that the amendments and arguments in the response to the Non-Final Office Action are insufficient or fail to be persuasive, the Patent Examiner will likely prepare and issue a Final Office Action.

A Final Action is issued when the response to the Non-Final Office Action fails to remedy or adequately address all of the issues raised in the Non-Final Office Action, or when the response raises new issues that impede the allowance of the claims.

From a practical point of view, Patent Examiners are required to review the amendments to the claims in a response to a Non-Final Office Action, but Patent Examiners may not be required to examine amendments or new arguments in a response to a Final Office Action, except in limited circumstances. 37 C.F.R. 1.116(b) states that amendments after a Final Office Action are allowed for (1) canceling claims or complying with any requirement of form expressly outlined in a previous Office Action, (2) presenting rejected claims in better form for consideration on appeal, or (3) touching the merits of the application upon a showing of good and sufficient reasons why the amendment is necessary and was not earlier presented.

Final Thoughts and Tips for Success

Facing a USPTO Office Action can initially seem daunting. Yet, with a clear understanding and strategic approach, overcoming these hurdles is entirely achievable. Remember, timely and comprehensive responses are key. Engaging with a knowledgeable patent law firm or patent agent can also provide invaluable guidance through this complex process.
