KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398 (2007)
Primary Holding
The Supreme Court held that the "teaching, suggestion, or motivation" (TSM) test used by the Federal Circuit to determine obviousness under 35 U.S.C. § 103 is too rigid and does not align with the statutory language, allowing for a more flexible approach that considers the totality of the circumstances surrounding the invention. This ruling emphasizes that a patent claim may be deemed obvious based on the knowledge of a person having ordinary skill in the art, without requiring explicit motivation to combine prior art references.
In the case of KSR International Co. v. Teleflex Inc., the Supreme Court decided that the way to determine if an invention is obvious (and therefore not eligible for a patent) needed to be more flexible. This matters because it helps prevent companies from getting patents on ideas that are too similar to existing products, which can keep prices down and encourage more competition in the market. For consumers, this ruling protects your rights by ensuring that patents are only granted for truly innovative ideas, not just minor tweaks on existing technologies. This case is relevant if you’re buying products that might be affected by patents, as it helps ensure that you have access to a wider variety of choices and potentially lower prices.

In the case of KSR International Co. v. Teleflex Inc., Teleflex and its subsidiary Technology Holding Company filed a lawsuit against KSR International Company for allegedly infringing United States Patent No. 6,237,565 B1, known as the Engelgau patent. This patent, held exclusively by Teleflex, pertains to an "Adjustable Pedal Assembly With Electronic Throttle Control," which describes a mechanism that integrates an electronic sensor with an adjustable automobile pedal to relay the pedal's position to a computer controlling the vehicle's throttle. KSR countered the infringement claim by asserting that the patent was invalid under 35 U.S.C. §103 due to its obviousness, arguing that the combination of elements in the patent was already known in the prior art. The procedural history leading to the Supreme Court involved KSR's challenge to the Federal Circuit's application of the "teaching, suggestion, or motivation" (TSM) test, which the court used to assess the obviousness of the Engelgau patent. KSR contended that the Federal Circuit's approach was inconsistent with the statutory requirements of §103. The case was initially decided by the Federal Circuit, which upheld the validity of the patent, prompting KSR to seek certiorari from the Supreme Court. The Supreme Court granted the writ and ultimately reversed the Federal Circuit's decision, indicating that the lower court had misapplied the standard for determining obviousness. The background context of this case highlights the ongoing debate over patent law, particularly regarding the standards for obviousness and the criteria used to evaluate patent claims. The Engelgau patent's subject matter was at the intersection of automotive technology and electronic control systems, raising questions about innovation and the boundaries of patent protection in rapidly evolving fields. The Supreme Court's ruling aimed to clarify the standards for patent obviousness, moving away from the strict TSM test employed by the Federal Circuit and emphasizing a more flexible approach that considers the broader context of prior art and the knowledge of skilled practitioners in the relevant field.
Whether the Court of Appeals for the Federal Circuit's application of the "teaching, suggestion, or motivation" test for determining obviousness under 35 U.S.C. §103 is consistent with the statutory requirements and precedents established by the Supreme Court.
The judgment of the Court of Appeals is reversed, and the case remanded for further proceedings consistent with this opinion.

eBay Inc. v. MercExchange, L. L. C., 547 U.S. 388 (2006)
Consumer LostA federal court considering whether to award permanent injunctive relief in patent infringement cases must apply the traditional four-factor test used in equity, which requires the plaintiff to demonstrate irreparable injury, inadequacy of legal remedies, a balance of hardships favoring the plaintiff, and that the public interest would not be disserved by the injunction.
Quanta Computer, Inc. v. LG Electronics, Inc., 553 U.S. 617 (2008)
Consumer WonThe doctrine of patent exhaustion applies to method patents, and the authorized sale of components that substantially embody the patents in suit exhausts the patent rights associated with those components.
Merck KGaA v. Integra Lifesciences I, Ltd., 545 U.S. 193 (2005)
Consumer LostThe Supreme Court held that the exemption from patent infringement under 35 U.S.C. §271(e)(1) applies to uses of patented inventions in preclinical research, even if the results are not ultimately included in a submission to the FDA, as long as those uses are reasonably related to the development and submission of information required by federal law regulating drugs.
Laboratory Corp. of America Holdings v. Metabolite Laboratories, Inc., 548 U.S. 124 (2006)
Consumer LostA patent cannot claim a monopoly over a basic scientific relationship, such as the correlation between homocysteine levels and vitamin deficiencies, as this falls under the exclusion of laws of nature and natural phenomena from patent protection.
