Eldred v. Ashcroft, 537 U.S. 186 (2003), was a decision by the Supreme Court of the United States upholding the constitutionality of the 1998 Sonny Bono Copyright Term Extension Act (CTEA). The practical result of this was to prevent a number of works from entering the public domain in 1998 and following years, as would have occurred under the Copyright Act of 1976. Materials which the plaintiffs had worked with and were ready to republish were now unavailable due to copyright restrictions.
Neither software nor computer programs are explicitly mentioned in statutory United States patent law. Patent law has changed to address new technologies, and decisions of the United States Supreme Court and United States Court of Appeals for the Federal Circuit (CAFC) beginning in the latter part of the 20th century have sought to clarify the boundary between patent-eligible and patent-ineligible subject matter for a number of new technologies including computers and software. The first computer software case in the Supreme Court was Gottschalk v. Benson in 1972. Since then, the Supreme Court has decided about a half dozen cases touching on the patent eligibility of software-related inventions.
State Street Bank and Trust Company v. Signature Financial Group, Inc., 149 F.3d 1368, also referred to as State Street or State Street Bank, was a 1998 decision of the United States Court of Appeals for the Federal Circuit concerning the patentability of business methods. State Street for a time established the principle that a claimed invention was eligible for protection by a patent in the United States if it involved some practical application and, in the words of the State Street opinion, "it produces a useful, concrete and tangible result."
Business method patents are a class of patents which disclose and claim new methods of doing business. This includes new types of e-commerce, insurance, banking and tax compliance etc. Business method patents are a relatively new species of patent and there have been several reviews investigating the appropriateness of patenting business methods. Nonetheless, they have become important assets for both independent inventors and major corporations.
Diamond v. Diehr, 450 U.S. 175 (1981), was a United States Supreme Court decision which held that controlling the execution of a physical process, by running a computer program did not preclude patentability of the invention as a whole. The high court reiterated its earlier holdings that mathematical formulas in the abstract could not be patented, but it held that the mere presence of a software element did not make an otherwise patent-eligible machine or process patent ineligible. Diehr was the third member of a trilogy of Supreme Court decisions on the patent-eligibility of computer software related inventions.
Patentable, statutory or patent-eligible subject matter is subject matter which is susceptible of patent protection. The laws or patent practices of many countries provide that certain subject-matter is excluded from patentability, even if the invention is novel and non-obvious. Together with criteria such as novelty, inventive step or nonobviousness, utility, and industrial applicability, which differ from country to country, the question of whether a particular subject matter is patentable is one of the substantive requirements for patentability.
Giles Sutherland Rich was an associate judge of the United States Court of Customs and Patent Appeals (CCPA) and later on was a United States Circuit Judge of the United States Court of Appeals for the Federal Circuit (CAFC), and had enormous impact on patent law. He was the first patent attorney appointed to any federal court since Benjamin Robbins Curtis was appointed to the Supreme Court in 1851.
A Markmanhearing is a pretrial hearing in a U.S. District Court during which a judge examines evidence from all parties on the appropriate meanings of relevant key words used in a patent claim, when patent infringement is alleged by a plaintiff. It is also known as a "Claim Construction Hearing".
Gottschalk v. Benson, 409 U.S. 63 (1972), was a United States Supreme Court case in which the Court ruled that a process claim directed to a numerical algorithm, as such, was not patentable because "the patent would wholly pre-empt the mathematical formula and in practical effect would be a patent on the algorithm itself." That would be tantamount to allowing a patent on an abstract idea, contrary to precedent dating back to the middle of the 19th century. The ruling stated "Direct attempts to patent programs have been rejected [and] indirect attempts to obtain patents and avoid the rejection ... have confused the issue further and should not be permitted." The case was argued on October 16, 1972, and was decided November 20, 1972.
The Copyright Clause describes an enumerated power listed in the United States Constitution.
In re Bilski, 545 F.3d 943, 88 U.S.P.Q.2d 1385, was an en banc decision of the United States Court of Appeals for the Federal Circuit (CAFC) on the patenting of method claims, particularly business methods. The Federal Circuit court affirmed the rejection of the patent claims involving a method of hedging risks in commodities trading. The court also reiterated the machine-or-transformation test as the applicable test for patent-eligible subject matter, and stated that the test in State Street Bank v. Signature Financial Group should no longer be relied upon.
Dann v. Johnston, 425 U.S. 219 (1976), is a decision of the United States Supreme Court on the patentability of a claim for a business method patent.
Bilski v. Kappos, 561 U.S. 593 (2010), was a case decided by the Supreme Court of the United States holding that the machine-or-transformation test is not the sole test for determining the patent eligibility of a process, but rather "a useful and important clue, an investigative tool, for determining whether some claimed inventions are processes under § 101." In so doing, the Supreme Court affirmed the rejection of an application for a patent on a method of hedging losses in one segment of the energy industry by making investments in other segments of that industry, on the basis that the abstract investment strategy set forth in the application was not patentable subject matter.
AT&T Corp. v. Excel Communications, Inc., 172 F.3d 1352 was a case in which the United States Court of Appeals for the Federal Circuit reversed the decision of the United States District Court for the District of Delaware, which had granted summary judgment to Excel Communications, Inc. and decided that AT&T Corp. had failed to claim statutory subject matter with U.S. Patent No. 5,333,184 under 35 U.S.C. § 101. The United States Court of Appeals for the Federal Circuit remanded the case for further proceedings.
CyberSource Corp. v. Retail Decisions, Inc., 654 F.3d 1366, is a United States Court of Appeals for the Federal Circuit case that disputed patent eligibility for the '154 patent, which describes a method and system for detecting fraud of credit card transactions through the internet. This court affirmed the decision of United States District Court for the Northern District of California which ruled that the patent is actually unpatentable.
Alice Corp. v. CLS Bank International, 573 U.S. 208 (2014), was a 2014 United States Supreme Court decision about patent eligibility. The issue in the case was whether certain patent claims for a computer-implemented, electronic escrow service covered abstract ideas, which would make the claims ineligible for patent protection. The patents were held to be invalid because the claims were drawn to an abstract idea, and implementing those claims on a computer was not enough to transform that abstract idea into patentable subject matter.
Journal of Intellectual Property Law is a biannual student-edited law review covering intellectual property law published by the University of Georgia School of Law. The journal covers trademarks, patents, copyright law, trade secrets, internet law, and sports and entertainment law.
United States v. Arthrex, Inc., 594 U.S. ___ (2021), was a United States Supreme Court case related to the Appointments Clause of the United States Constitution as it related to patent judges on the Patent Trial and Appeal Board (PTAB). In a complex decision, the Court ruled that these judges were considered "primary officers" under the Appointments Clause, normally subject to appointment through the US President and the US Senate, but to remedy the matter, the Court ruled that the constitutional issue is resolved by allowing the PTAB decisions to be subject to review by the appropriately-appointed Director of the Patent Office.
Minerva Surgical, Inc. v. Hologic, Inc., 594 U.S. ___ (2021), was a United States Supreme Court case dealing with the principle of assignor estoppel and its application. The Supreme Court reaffirmed the principle of assignor estoppel, however with the exception that the doctrine is only applied when assignors assertions are actually consistent with previous representations as to the patent. The majority decision was written by Justice Elena Kagan, with Justice Samuel Alito and Justice Amy Coney Barrett filing separate dissenting opinions.
