35 U.S.C. § 101 is one of the most disputed and complex provisions of patent law. This is an aspect that all startups, inventors, and patenting specialists can agree on. The original purpose was to serve as a check on patent eligibility. However, the current state of this U.S. federal statute is the epicentre of the current legislative and legal battle over innovation.
The question of patent eligibility is no longer contingent on the simple wording of a statutory provision. The judicial interpretation of this statutory provision has changed the manner in which innovation is evaluated. A simple question under 35 U.S.C. 101 has now become a complex question.
This is more than a simple legal question. It has implications for startup funding and value. It also has implications for international filing. Inventors and firms must focus on making a strong argument for technological advancement to meet the eligibility requirements.
Key Takeaways
How has Patent Eligibility Evolved Over the Years?
Patent eligibility refers to the idea that an invention is reachable within defined categories of the U.S. law. An invention cannot be patented unless it is a subject matter eligible under 35 U.S.C. § 101.
The statutory language of § 101 is curiously simple. It reads:
“Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.”
Laws of nature (natural phenomena) and abstract ideas are known judicial exceptions; it has specifically impacted biotech and software innovators.

Reasons and Decisions That Evolved the Eligibility Criteria
There are two big reasons behind the rapid evolution of patent eligibility.
Judicial Uncertainty and Limits
Court decisions like Alice and Mayo made stricter eligibility rules. Many innovations were vulnerable to invalidation or rejection. These rulings were meant to prevent monopolization of basic principles, but they also ended up making unpredictability in the patent system.
Competitive Pressures
Many regions allow broader protection for technological advancement. The U.S. rules are narrower in comparison to global standards; investors risk a lot of competitive ground in the U.S. This is why you hear prompted calls to evolve U.S. policy and patent strategy.
Several Supreme Court decisions have practically reshaped § 101:
- Mayo Collaborative Services v. Prometheus (2012). A diagnostic method was invalidated for its reliance on a law of nature.
- Association for Molecular Pathology v. Myriad Genetics (2013). Ruled that natural DNA sequences are not patentable.
- Alice Corp. v. CLS Bank International (2014). Rejected software claims as abstract ideas, which are unpatentable.
Keep all of this in your mind when you are patent hunting.
The Patent Eligibility Restoration Act of 2023
The Patent Eligibility Restoration Act of 2023 was introduced by Senators Chris Coons and Thom Tillis in June 2023. The aim was to reform § 101. The bill seeks to establish more defined lines regarding exclusion as well as strike judicial exclusions.
It is important to investors because it impacts:
Portfolio Value. Less commercial banking due to uncertain protection.
Funding & Investment. Significant market leverage and IP enhancement of licensing.
Global Strategy. Aligning global filings with U.S. protection is essential.
Expert Tip
“Frame your invention around measurable technical improvement. Demonstrate practical application beyond mental processes or abstract concepts. Draft claims with precision and strategic foresight.”

Former Acting Director, U.S. Patent and Trademark Office
How to Improve Your Patent Bar Eligibility
Applicants must satisfy the criteria of technical or scientific education qualifications under A or B or C categories to become a USPTO patent agent. Ensure that you consider the following:
Passing the USPTO Registration Examination (patent bar).
Satisfying 37 CFR § 11.7 and having good moral character.
Explain how your invention improves technical performance.
Non-citizens may obtain limited recognition from time to time, allowing limited practice at the USPTO. Be prepared for more:
- Record the details of the application and its progress.
- Organize your claims by consulting an experienced patent attorney.
- Explain the purpose and service of your invention in simple terms.
- Provide easy information about technical details.
- Use diagrams and flowcharts or system architecture for clarity.
- Provide examples that highlight your invention in terms of practicality.
- Provide competitive context.
- Inform about time and business objectives.
- Keep yourself updated about § 101 restrictions if you are in AI and software and diagnostics.
- Construct a strategic claim to make a lasting impression.
- Do not keep yourself busy learning the law. That is not your task.
Adhere to all the above. Your eligibility for the patent agent exam will be unchallengeable.
