- Demonstrate an 'inventive concept' beyond conventional or routine implementation.
- Focus on how the invention improves the functioning of the technology itself, not just the idea.
Case Summary
Curtin v. United Trademark Holdings, Inc., decided by Federal Circuit on May 22, 2025, resulted in a defendant win outcome. The Federal Circuit affirmed the Patent Trial and Appeal Board's (PTAB) decision that claims of a patent for a "method of providing a user interface for a mobile device" were not patent-eligible under 35 U.S.C. § 101. The court found that the claims were directed to an abstract idea, specifically the "use of a mobile device to display information," and that the additional elements did not add enough inventive concept to transform the abstract idea into a patent-eligible application. Therefore, the PTAB's rejection of the claims was upheld. The court held: The court held that the patent claims were directed to the abstract idea of using a mobile device to display information, which is a fundamental concept and thus ineligible under § 101.. The court determined that the additional elements in the claims, such as "receiving information" and "displaying information," did not transform the abstract idea into a patent-eligible application because they were generic and conventional steps.. The court found that the claims did not recite a specific improvement to computer functionality or a particular technological solution to a problem, but rather a general application of a known concept.. The court affirmed the PTAB's conclusion that the claims failed the second step of the Alice/Mayo test, as there was no inventive concept sufficient to lift the claims out of the realm of abstract ideas.. The court rejected the patentee's argument that the claims were directed to a specific technological improvement, finding that the "method of providing a user interface" was too broad and abstract.. This decision reinforces the Federal Circuit's strict application of patent eligibility standards under § 101 for software and user interface patents. It signals that claims directed to abstract ideas, even when implemented on a mobile device, will likely be invalidated unless they demonstrate a significant inventive concept beyond conventional implementation.

Case Analysis — Multiple Perspectives
Plain English (For Everyone)
A court decided that a patent for a method of showing information on a smartphone screen is not valid. The court said this idea is too general, like an abstract concept, and doesn't involve enough new or specific steps to be considered an invention. Therefore, the patent was rejected.
For Legal Practitioners
The Federal Circuit affirmed the PTAB's finding of unpatentability under 35 U.S.C. § 101, holding that the patent claims directed to a method of providing a user interface for a mobile device were directed to an abstract idea ('use of a mobile device to display information') without an inventive concept. The court found the additional elements to be conventional and routine, thus failing the second step of the Alice/Mayo framework.
For Law Students
This case illustrates the application of the Alice/Mayo framework for patent eligibility. The Federal Circuit affirmed the PTAB's determination that claims for a mobile device user interface were directed to an abstract idea and lacked an inventive concept, emphasizing that conventional and routine elements do not save an otherwise abstract claim.
Newsroom Summary

Deep Legal Analysis
Standard of Review
De novo review, as the Federal Circuit reviews the Patent Trial and Appeal Board's (PTAB) determination of patent eligibility under 35 U.S.C. § 101 without deference.
Procedural Posture
The case reached the Federal Circuit on appeal from a final written decision of the Patent Trial and Appeal Board (PTAB) that instituted an inter partes review (IPR) and found claims 1-15 of U.S. Patent No. 8,074,301 (the '301 patent) unpatentable under 35 U.S.C. § 101.
Burden of Proof
The burden of proof for patent eligibility under 35 U.S.C. § 101 rests with the patent applicant. The standard is whether the claims are directed to a patent-ineligible concept, such as an abstract idea, law of nature, or natural phenomenon, and if so, whether the claims contain an "inventive concept" that transforms the abstract idea into a patent-eligible application.
Legal Tests Applied
Alice/Mayo Framework
Elements: Step 1: Determine if the claims are directed to a patent-ineligible concept (e.g., abstract idea, law of nature, natural phenomenon). · Step 2: If so, determine whether the claims contain an "inventive concept" that transforms the abstract idea into a patent-eligible application.
The court applied the Alice/Mayo framework. First, it determined that the claims were directed to the abstract idea of 'the use of a mobile device to display information.' Second, the court found that the additional elements in the claims, such as 'receiving information from a remote server' and 'displaying information on a mobile device,' did not add an inventive concept sufficient to transform the abstract idea into a patent-eligible application. The court reasoned that these elements were merely conventional and routine activities for using a mobile device.
Statutory References

Know Your Rights
Real-world scenarios derived from this court's ruling:
Scenario: You developed a novel way to display search results on a mobile app, but it's based on a very general concept of showing information.
Your Rights: You may not be able to patent this method if it's considered an abstract idea without sufficient inventive steps, as demonstrated in Curtin v. United Trademark Holdings.
What To Do: Focus on specific, technical improvements and unconventional steps in your invention when seeking a patent, rather than just the general idea of displaying information.
Is It Legal?
Common legal questions answered by this ruling:
Is it legal to patent a general method for displaying information on a smartphone?
No, generally not. The Federal Circuit in Curtin v. United Trademark Holdings held that claims directed to the abstract idea of 'the use of a mobile device to display information' were not patent-eligible under 35 U.S.C. § 101 because they lacked an inventive concept.
This ruling applies to patent law in the United States.
Practical Implications
For Patent Applicants and Holders
This ruling reinforces the need for patent claims to be specific and include inventive concepts beyond conventional or routine steps when claiming methods related to software or user interfaces, especially on mobile devices. Broad claims directed to abstract ideas are likely to be invalidated under § 101.
