In the United States, federal law supersedes state law, meaning that federal law takes precedence when the two conflict. This is known as the Supremacy Clause, which is derived from Article VI of the US Constitution. An example of this is the legalization of marijuana in certain states, which is still classified as a Schedule I Drug under federal law. However, the federal government has limited ways to enforce its laws on the state level, and states have authority over matters within their borders. This has resulted in situations where individuals comply with state law but violate federal law, and vice versa.

What You'll Learn
Supremacy Clause
The Supremacy Clause is a significant structural provision of the US Constitution, establishing federal law as superior to state law. This clause was included in the Constitution in response to the problems with the Articles of Confederation, which lacked a similar provision and resulted in federal statutes not binding state courts. The Supremacy Clause ensures that federal law prevails when there is a clash with state law, provided that the federal law is constitutional.
The clause gives the Supreme Court the power to review state court decisions involving issues arising under the Constitution and federal law. The Court can interpret the Constitution and overrule state court decisions. The Supremacy Clause has been used by the Supreme Court to establish a robust role for the federal government and reinforce the division of federal and state powers.
The clause has been applied in several early-20th-century Supreme Court decisions, developing the doctrine of field preemption. This doctrine states that some federal legislation implicitly prevents states from adopting laws on the same subject. Federal law can expressly preempt state law by including explicit language or implicitly through its structure and purpose.
The Supremacy Clause also allows the federal government to make treaties that supersede state law, even if they abrogate states' rights under the Tenth Amendment. However, the enforceability of treaties has been limited by Supreme Court decisions, requiring congressional action or explicit "self-executing" language for a treaty to be binding domestic law.

Federal preemption
In the United States, federal law supersedes state law, meaning that state laws can be overridden by federal laws. This is known as the Supremacy Clause, which is a key provision in Article VI of the US Constitution. The Supremacy Clause establishes the doctrine of "preemption", which states that federal law takes precedence over state law in most cases of conflicting laws.
The Supremacy Clause ensures that federal law is supreme within the United States and that any conflicts between federal and state laws are resolved in favour of the federal government. This clause was established to prevent constitutional issues, as allowing state laws to supersede federal laws would mean that "the authority of the whole society [would be] subordinate to the authority of the parts".
The Supreme Court has affirmed the Supremacy Clause in several cases, including Marbury v. Madison (1803), where the Court held that Congress cannot pass laws contrary to the Constitution and that the Judicial system is responsible for interpreting the Constitution. In Martin v. Hunter's Lessee (1816) and Cohens v. Virginia (1821), the Court further affirmed its power to review and overrule state court decisions involving federal law and constitutional interpretation.
It is important to note that the federal government cannot automatically compel states to enforce federal laws. For example, despite federal laws prohibiting marijuana, some states have legalized medical or recreational marijuana use. In these cases, the federal government has chosen not to enforce its laws strictly, allowing states to implement their own regulations.

State regulatory activity
The Supremacy Clause of the US Constitution, a key provision appearing in Article VI, addresses the conflict between state and federal laws. The Supremacy Clause establishes that federal law supersedes state law in many—but not all—cases of conflicting laws, provided the federal law is constitutional.
The Supreme Court has interpreted the Supremacy Clause and Article III as granting it the ultimate power to review state court decisions involving issues arising under the Constitution and laws of the United States. The Court has the final say in matters involving federal law, including constitutional interpretation, and can overrule decisions by state courts.
The area of law that addresses the conflict between state and federal laws is known as preemption. Preemption can arise in any area over which Congress has authority, but it is most often an issue in areas where Congress and the states share authority. Preemption applies when federal laws and regulations have so thoroughly covered a particular field that no room remains for the states.

Federal vs. state marijuana laws
In the United States, federal law is supreme within the country. The Supremacy Clause dictates that federal law overrides state law when there is a conflict, as long as the federal law is constitutional. This was established in 1865.
Despite this, the Tenth Amendment limits what state laws can be federally preempted. While the federal government can enforce its marijuana laws, requiring state agents to enforce these laws is unconstitutional. This is known as the anticommandeering rule. The federal government has never alleged in court that federal law preempts state medical marijuana laws, and the Department of Justice has even argued in favour of dismissing a lawsuit claiming that Arizona's medical marijuana law was preempted.
The Controlled Substances Act (CSA) also makes it clear that it only preempts state laws under very limited circumstances. The CSA will only preempt a state law if it is “physically impossible" to comply with both state and federal law, or if the state law stands as an obstacle to the CSA. This is not the case with carefully crafted state medical marijuana programs.
While marijuana possession and distribution are federal crimes under the CSA, this has not stopped states from legalising cannabis for adults' or medical use. As of 2022, 37 states, the District of Columbia, and four US territories allow for the use of medical marijuana. 13 states and one territory have decriminalised the use of cannabis, and 18 states, two territories, and the District of Columbia have enacted laws to allow the recreational use of marijuana.
The conflict between federal and state laws has created business law complications, particularly regarding banking rules and regulations. It has also led to consumer confusion, as the market is now saturated with hemp and CBD products that may or may not be allowed under federal law.

Federal patent laws
In the United States, federal law takes precedence over state law when there is a conflict between the two. This is based on the Supremacy Clause, which establishes that federal law is supreme within the country. However, for federal law to override state law, it must be passed in accordance with the Constitution, and the Supremacy Clause also applies to local laws.
The United States Patent and Trademark Office (USPTO) is the authority responsible for examining and granting patents. Patents can be utility, design, or plant patents. Utility patents are the most common type and last for 20 years from the filing date, becoming enforceable on the day of issuance. Design patents protect ornamental designs, while plant patents protect new varieties of asexually reproducing plants.
The process of obtaining a patent involves submitting an application to the USPTO, which is then reviewed by an examiner to determine if the invention is patentable. Patent validity can be challenged in US Federal District Courts, and these courts also have primary jurisdiction in patent infringement cases. The US Court of Appeals for the Federal Circuit reviews decisions made by the Federal District Courts and the Patent Trial and Appeal Board (PTAB).
The US patent system has been characterised by its strong pro-patentee legal regime, extensive case law, and large economy. This has made US patents more valuable and litigated than those of any other country.
