347-787-6824Patent law is often misunderstood, especially when it comes to the terms patent litigation and patent prosecution. These two processes serve completely different purposes, but both are essential in protecting intellectual property. Knowing the difference helps inventors, businesses, and entrepreneurs navigate the complex world of patents more confidently.
This guide breaks down both processes in clear, simple language and shows why partnering with a skilled team of registered U.S. Patent Attorneys, like the LAW FIRM OF DAYREL SEWELL, PLLC, is crucial.
What Is Patent Litigation?
Patent litigation is the legal process that occurs when someone believes a patent has been infringed. In other words, it happens when parties disagree about patent rights, validity, or use.
This typically involves issues like:
- Patent infringement
- Patent dispute between two companies
- Challenges to a patent’s validity (also called patent invalidation)
- Defense against a patent infringement lawsuit
Patent litigation is handled in U.S. federal courts, and the outcomes can significantly impact entire industries.

How Patent Litigation Works?
A typical litigation process includes:
- Filing the Complaint – A patent owner files a lawsuit alleging that another party used their invention without permission.
- Determining Jurisdiction – Patent cases fall under federal jurisdiction, with appeals being heard by the Court of Appeals for the Federal Circuit.
- Discovery – Both sides gather evidence, technical documents, prototypes, and expert reports.
- Claim Construction (Markman Hearing) – The court determines the legal meaning and scope of each patent claim.
- Trial or Settlement – Many cases settle, but high-profile disputes often proceed to trial.
- Judgment – The court decides on infringement, invalidation, and damages.
What Is Patent Prosecution?
Patent prosecution involves preparing, filing, and negotiating a patent application with the United States Patent and Trademark Office (USPTO).
What Is the Process of Patent Prosecution?
The patent prosecution process generally includes:
- Patent search and analysis
- Drafting and filing the application
- USPTO examination
- Responses to Office Actions
- Allowance or final rejection
When handled by an experienced attorney, prosecution becomes more strategic and increases the chances of patent approval.

Key Differences Between Patent Litigation and Patent Prosecution
The most significant difference between these two areas is their purpose. Patent prosecution establishes a patent, while patent litigation enforces or challenges it. Prosecution occurs before the USPTO, whereas litigation takes place in federal courts. Litigation is adversarial and evidence-driven, while prosecution is collaborative and administrative. Patent litigators argue cases; patent prosecutors craft applications. Litigation resolves disputes such as infringement or invalidation, while prosecution builds the patent foundation that may later be defended in court.
Both areas complement each other, and a strong intellectual property strategy requires an understanding of how each protects innovation at different stages of development.

FAQs
What is a patent litigator?
A patent litigator is a specialized attorney who represents clients in patent-related disputes, including patent infringement lawsuits, patent invalidation challenges, and complex patent dispute matters.
What is a patent prosecutor?
A patent prosecutor, also known as a patent prosecution lawyer, is an attorney licensed to practice before the USPTO. Their role is to prepare, file, and manage patent applications, draft strong patent claims, and respond to examiner rejections.
What percentage of patents are litigated?
Only a small portion of all issued patents ever end up in court. Studies show that roughly 1%–3% of patents are litigated, meaning most inventions never become the subject of a patent lawsuit.
What is patent invalidation?
Patent invalidation is a legal process in which one party challenges the validity of an issued patent, often during a patent infringement lawsuit. The goal is to prove the patent should never have been granted due to issues such as prior art, lack of novelty, or obviousness.
What is the Patent Prosecution Highway?
The Patent Prosecution Highway (PPH) is an international program that allows applicants to accelerate the examination of a patent application. If a corresponding application has already received a favorable ruling from another participating patent office, the USPTO may fast-track the review process. This can significantly shorten the time it takes to complete the patent prosecution process. The PPH is especially useful for inventors filing patents in multiple countries and seeking quicker approval.
