Issue
Whether a mixture of naturally occurring bacteria is patent-eligible.
Held
The patent is invalid because the mixture is a natural phenomenon not invented by man.
Exam use
In an exam, introduce Funk Brothers Seed Co. v. Kalo Inoculant Co. with the citation only if you can remember it accurately; otherwise use the case name and court, then focus on the rule and application. A strong answer should say what Funk Brothers Seed Co. v. Kalo Inoculant Co. decided, why the facts mattered, and how the authority helps resolve the new facts. Avoid treating the case as a decorative reference. Use it to prove a doctrinal step in Patent eligibility of natural phenomena, then move quickly to analysis.
Summary
Funk Brothers Seed Co. v. Kalo Inoculant Co. is included in the Quantum Computing Law case database because it gives students a concrete authority for Patent eligibility of natural phenomena. The reported citation is 333 U.S. 127, and the decision is associated with Supreme Court of the United States. In revision, treat the case as a way to connect the legal issue to a real dispute rather than as an abstract rule. The key exam move is to state the holding, identify the fact pattern that made the rule matter, and then decide whether a new problem question should apply, distinguish, or limit the authority.
Facts
The material factual signal for Funk Brothers Seed Co. v. Kalo Inoculant Co. is: Kalo patented a mixture of bacterial strains for legume inoculation that occurred naturally. Students should read the linked source and turn that signal into a short fact table: parties, transaction or public-law setting, procedural posture, conduct in dispute, and the fact the court treated as decisive. This prevents vague case-dropping. In an answer on Quantum Computing Law, use the facts to explain why Patent eligibility of natural phenomena was live, then compare the problem facts against the facts in the case before stating any conclusion.
Procedural History
Funk Brothers Seed Co. v. Kalo Inoculant Co. is reported as a decision of Supreme Court of the United States. The procedural route should be checked against the linked source before formal citation. For study notes, record whether the decision was an appeal, judicial review, trial judgment, tribunal ruling, or constitutional/application proceeding, because that posture affects how confidently the rule can be used.
Issue
Whether a mixture of naturally occurring bacteria is patent-eligible.
Held
The patent is invalid because the mixture is a natural phenomenon not invented by man.
Ratio Decidendi
Natural phenomena are not patentable, even if newly discovered, unless there is a human-made change that provides a new use.
Obiter Dicta
Check the linked source for concurring, dissenting, or obiter observations before quoting this case. If the case includes non-binding reasoning, use it as persuasive support rather than as the core rule.
Reasoning
For reasoning, start with the ratio: Natural phenomena are not patentable, even if newly discovered, unless there is a human-made change that provides a new use. Then read the source and separate three things: the legal test, the facts used to apply that test, and any policy or institutional reason the court gave. This structure makes Funk Brothers Seed Co. v. Kalo Inoculant Co. easier to use in essays and problem questions. In Quantum Computing Law, the case should be compared with related authorities on Patent eligibility of natural phenomena; if the jurisdiction, statute, or procedural posture differs from the exam problem, explain that limit explicitly instead of treating the authority as automatic.
Plain-English Explanation
Plainly, Funk Brothers Seed Co. v. Kalo Inoculant Co. is a case to use when a Quantum Computing Law answer needs an authority on Patent eligibility of natural phenomena. Do not just list it. Explain the problem the court had to solve, the rule or holding it used, and the fact that made the result persuasive. That turns the case from a memorised name into evidence for your legal analysis.
