Williams v. Collins
Headline: Federal Circuit Affirms Patentability of Targeted Drug Treatment Method
Citation: 131 F.4th 1325
Brief at a Glance
Patent for a specific drug treatment of a genetic mutation is valid because it's a concrete application, not an abstract idea.
- Focus patent claims on specific applications, not just general concepts.
- Clearly articulate the concrete steps and components of a medical treatment method.
- Distinguish your invention from abstract ideas by highlighting its practical implementation.
Case Summary
Williams v. Collins, decided by Federal Circuit on March 19, 2025, resulted in a plaintiff win outcome. The case concerns the patentability of a method for treating a patient with a specific genetic mutation using a particular drug. The Federal Circuit affirmed the district court's grant of summary judgment, holding that the patent claims were not directed to an "abstract idea" under the Alice/Mayo framework. The court found the claims were tied to a specific, concrete application of a drug to a patient with a particular genetic makeup, distinguishing it from abstract mental processes or mathematical formulas. The court held: The patent claims are not directed to an abstract idea because they are tied to a specific, concrete application of a drug to a patient with a particular genetic makeup, thus satisfying the first step of the Alice/Mayo test.. The claims involve a specific treatment method that is more than a mere diagnostic or natural phenomenon, as it involves the affirmative act of administering a drug.. The court distinguished the claims from abstract ideas by emphasizing the practical application and the specific limitations imposed by the genetic mutation and the drug.. The patent claims are eligible for patent protection because they represent a specific and practical application of scientific knowledge to improve human health.. This decision provides clarity for the patentability of medical treatment methods, particularly those involving personalized medicine and genetic targeting. It reinforces that claims detailing specific applications of drugs to patients with particular genetic profiles are likely to survive challenges under the abstract idea exception, encouraging innovation in the pharmaceutical and biotechnology sectors.

Deep Legal Analysis
Standard of Review
De novo review, as the appeal concerns the interpretation of patent law and the application of the Alice/Mayo framework to patent claims.
Procedural Posture
Appeal from the U.S. District Court for the District of Delaware, which granted summary judgment in favor of the patent holder.
Burden of Proof
The patent challenger bears the burden of proving that the patent claims are invalid. The standard is whether the claims are directed to an abstract idea under the Alice/Mayo test.
Legal Tests Applied
Alice/Mayo Test
Elements: Step 1: Determine if the patent claim is directed to a patent-ineligible concept (e.g., abstract idea, law of nature, natural phenomenon). · Step 2: If so, determine whether the claim elements, individually and as an ordered combination, transform the nature of the claim into a patent-eligible application.
The Federal Circuit found the claims were not directed to an abstract idea at Step 1. The court reasoned that the claims were tied to a specific, concrete application: treating a patient with a specific genetic mutation (e.g., KRAS G12C) using a particular drug (e.g., sotorasib). This specificity distinguished the claims from mere abstract ideas or diagnostic methods. Therefore, Step 2 was not reached.
Statutory References
| 35 U.S.C. § 101 | Inventions patentable — This statute defines what subject matter is eligible for patent protection. The Alice/Mayo test is used to determine patent eligibility under this section, particularly for claims involving abstract ideas, laws of nature, or natural phenomena. |

Precedent cases cited or related to Williams v. Collins: Alice Corp. v. CLS Bank Int'l, 573 U.S. 208 (2014); Mayo Collaborative Servs. v. Prometheus Labs., Inc., 566 U.S. 66 (2012).
Q: What is the Alice/Mayo test?
The Alice/Mayo test is a two-step framework used to determine if patent claims are eligible under 35 U.S.C. § 101. It first asks if the claim is directed to an abstract idea, and if so, whether the claim elements transform the idea into a patent-eligible application.
Q: Did the court find the patent claims to be an abstract idea?
No, the Federal Circuit found that the claims were not directed to an abstract idea. The court emphasized that the claims were tied to a specific, concrete application of treating a patient with a particular genetic makeup using a specific drug.
Q: What does 'patent eligibility' mean?
Patent eligibility refers to whether an invention falls within the categories of subject matter that can be patented, such as processes, machines, manufactures, or compositions of matter, and does not fall into judicially created exceptions like abstract ideas, laws of nature, or natural phenomena.
Q: What statute governs patent eligibility?
Patent eligibility in the U.S. is primarily governed by 35 U.S.C. § 101, which defines patentable subject matter. The Alice/Mayo test is a judicial interpretation of this statute.
Q: Why is specificity important in patent claims for medical treatments?
Specificity is crucial because it helps demonstrate that the claims are tied to a concrete application rather than a general, abstract concept, which is a key factor in passing the Alice/Mayo test for patent eligibility.
Q: What is a 'concrete application' in patent law?
A 'concrete application' refers to an invention that is tied to a specific, tangible use or implementation, as opposed to a general idea, mathematical formula, or mental process. The court found the drug treatment method to be a concrete application.
Q: Can diagnostic methods be patented?
Diagnostic methods can be patentable, but they are often subject to scrutiny under the Alice/Mayo test. The key is to demonstrate that the method is more than just an abstract idea or a natural phenomenon.
Q: Are there any exceptions to patent eligibility?
Yes, judicially created exceptions to patent eligibility include abstract ideas, laws of nature, and natural phenomena. Claims directed to these concepts may be ineligible unless they involve a significant inventive concept.
Q: What does 'de novo' review mean?
De novo review means the appellate court considers the case anew, without giving deference to the legal conclusions of the lower court. The Federal Circuit reviews patent eligibility questions de novo.
Q: How did the court distinguish this patent from prior abstract idea cases?
The court distinguished this case by emphasizing that the claims were tied to a specific, concrete application of a drug to a patient with a particular genetic makeup, rather than being a general diagnostic or treatment concept.
