The exhausted combination doctrine, also referred to as the doctrine of theLincoln Engineeringcase, is the doctrine of U.S. patent law that when an inventor invents a new, unobvious device and seeks to patent not merely the new device but also the combination of the new device with a known, conventional device with which the new device cooperates in the conventional and predictable way in which devices of those types have previously cooperated, the combination is unpatentable as an "exhausted combination" or "old combination". [1] The doctrine is also termed the doctrine of the Lincoln Engineering case because the United States Supreme Court explained the doctrine in its decision in Lincoln Engineering Co. v. Stewart-Warner Corp. [2]
In Lincoln Engineering, the inventor invented a new and improved coupling device to attach a nozzle to a grease gun. The patent, however, claimed the whole combination of grease gun, nozzle, and coupling. The Supreme Court stated that "the improvement of one part of an old combination gives no right to claim that improvement in combination with other old parts which perform no new function in the combination". [3] It then concluded that the inventor's "effort, by the use of a combination claim, to extend the monopoly of his invention of an improved form of chuck or coupler to old parts or elements having no new function when operated in connection with the coupler renders the claim void." [4]
This way of claiming an invention was termed “overclaiming,” because it inflated the royalty base for licensing and potentially effectuated a tie-in by means of which the patentee required users, for example, to purchase not only the couplings but the whole grease gun as well in order to use the invention. [5]
The Federal Circuit held in 1984 that this doctrine is outdated and no longer reflects the law. [6] In effect, the Federal Circuit overruled the Supreme Court on this point—or claimed that the passage of the 1952 patent recodification law had done so.
In its decision in Quanta Computer, Inc. v. LG Electronics, Inc. , [7] however, the Supreme Court seems to have assumed without any discussion that its old precedents such as Lincoln Engineering (uncited in the Quanta opinion) are still in force, as least with regard to the exhaustion doctrine. In Quanta, the Court considered the sale of a patented microprocessor to "exhaust" not only the patent on the microprocessor but the patent on a conventional personal computer (PC) containing the microprocessor, since the PC patent had essentially the same inventive concept (or departure from the prior art) as the microprocessor patent.
After 1984 it appeared that it was possible to obtain patents on old combinations, for example not only a new motor but also an otherwise conventional disc drive containing the new motor. It has also been held that the sale of the motor, in such a case, does not exhaust the patent on the disc drive containing the new motor. Hence, a purchaser of the motor who incorporated it into a disk drive would infringe the disk drive patent. [8] It is now uncertain whether such patents are valid. In any event, the Quanta decision appears to hold that the exhaustion doctrine shields from infringement liability the foregoing motor purchaser that incorporates the motor into a disk drive. [9]
Claiming a computer-related advance as an exhausted combination may provide a way to prevent the claimed advance from being classified as nonstatutory subject matter under section 101 of the US patent law. Placing a process that fails the machine-or-transformation test in a machine environment may overcome the absence of implementation by a specific machine, as required by In re Bilski and the Supreme Court decisions on which it is based. [10] (The successfulness of this expedient depends on acceptance of the Federal Circuit's abolition of the exhausted combination doctrine. [11] )
For example, the form of the processes claimed in Diamond v. Diehr , [12] Parker v. Flook , [13] and Gottschalk v. Benson [14] may appropriately be compared. In Diehr, the claim is to “a method of operating a rubber-molding press” and the claim contains at least minimal references to the press and other apparatus. In Flook, the claim is to a "method for updating the value of at least one alarm limit," where an “’alarm limit’ is a number.” The claim does not say anything about a reaction vessel or even temperature measuring devices. In Benson, the claim is to “a data processing method for converting binary coded decimal number representations into binary number representations.” One claim mentions a reentrant shift register and the other claim mentions no apparatus at all. In Flook, the claim could have instead been to “a method of operating a hydrocracking plant wherein hydrocarbon feedstock is placed into a chemical reactor, heat is applied, etc.” The claim, although to an exhausted combination, [15] would have required apparatus as did that in the Diehr case. Similarly, the claim in Benson could have been to a method of operating a telephone switch box or perhaps even a method of providing binary-coded-decimal numerical signals to a binary-coded operating device. Again, by providing a mechanical environment, even though it was an exhausted combination, the claims drafter might have avoided the holding of nonstatutory subject matter. It is possible that careful claims drafting techniques will succeed in elevating form over substance, to avoid the impact of the machine-or-transformation test.
The preceding analysis may have been overtaken by the Supreme Court's 2014 decision in Alice v. CLS Bank . In that case the Court confirmed and extended the legal analysis of its prior decisions in Parker v. Flook and Mayo v. Prometheus to claimed inventions involving implementations of computer algorithms, methods of doing business, and other methods of organizing human activity. The form of analysis that these cases dictate is that the presence of a machine, in particular a programmed digital computer, is not enough without more to assure patent eligibility. Rather, the implementation of the underlying idea must embody an "inventive concept." The inventive concept must provide "something extra" that extends beyond the algorithm or other idea, if an otherwise patent-ineligible claim is to be saved from patent ineligibility—according to these cases and recent lower court decisions that follow in their wake. [16]
Novelty is a requirement for a patent claim to be patentable. An invention is not new and therefore not patentable if it was known to the public before the filing date of the patent application, or before its date of priority if the applicant claims priority of an earlier patent application. The purpose of the novelty requirement is to prevent prior art from being patented again.
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.
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.
Parker v. Flook, 437 U.S. 584 (1978), was a 1978 United States Supreme Court decision that ruled that an invention that departs from the prior art only in its use of a mathematical algorithm is patent eligible only if there is some other "inventive concept in its application." The algorithm itself must be considered as if it were part of the prior art, and the claim must be considered as a whole. The case was argued on April 25, 1978 and was decided June 22, 1978. This case is the second member of the Supreme Court's patent-eligibility trilogy.
The exhaustion doctrine, also referred to as the first sale doctrine, is a U.S. common law patent doctrine that limits the extent to which patent holders can control an individual article of a patented product after a so-called authorized sale. Under the doctrine, once an authorized sale of a patented article occurs, the patent holder's exclusive rights to control the use and sale of that article are said to be "exhausted," and the purchaser is free to use or resell that article without further restraint from patent law. However, under the repair and reconstruction doctrine, the patent owner retains the right to exclude purchasers of the articles from making the patented invention anew, unless it is specifically authorized by the patentee to do so.
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.
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.
Freeman-Walter-Abele is a now outdated judicial test in United States patent law. It came from three decisions of the United States Court of Customs and Patent Appeals—In re Freeman, 573 F.2d 1237, In re Walter, 618 F.2d 758 ; and In re Abele, 684 F.2d 902 —which attempted to comply with then-recent decisions of the Supreme Court concerning software-related patent claims.
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.
Quanta Computer, Inc. v. LG Electronics, Inc., 553 U.S. 617 (2008), is a case decided by the United States Supreme Court in which the Court reaffirmed the validity of the patent exhaustion doctrine. The decision made uncertain the continuing precedential value of a line of decisions in the Federal Circuit that had sought to limit Supreme Court exhaustion doctrine decisions to their facts and to require a so-called "rule of reason" analysis of all post-sale restrictions other than tie-ins and price fixes. In the course of restating the patent exhaustion doctrine, the Court held that it is triggered by, among other things, an authorized sale of a component when the only reasonable and intended use of the component is to engage the patent and the component substantially embodies the patented invention by embodying its essential features. The Court also overturned, in passing, that the exhaustion doctrine was limited to product claims and did not apply to method claims.
In United States patent law, the machine-or-transformation test is a test of patent eligibility under which a claim to a process qualifies for consideration if it (1) is implemented by a particular machine in a non-conventional and non-trivial manner or (2) transforms an article from one state to another.
The Piano Roll Blues or Old Piano Roll Blues is a figure of speech designating a legal argument made in US patent law relating to computer software. The argument is that a newly programmed general-purpose digital computer is a "new" machine and, accordingly, properly the subject of a US patent.
United States v. Univis Lens Co., 316 U.S. 241 (1942), is a decision of the United States Supreme Court explaining the exhaustion doctrine and applying it to find an antitrust violation because Univis's ownership of patents did not exclude its restrictive practices from the antitrust laws. The Univis case stands for the proposition that when an article sold by a patent holder or one whom it has authorized to sell it embodies the essential features of a patented invention, the effect of the sale is to terminate any right of the patent holder under patent law to control the purchaser's further disposition or use of the article itself and of articles into which it is incorporated as a component or precursor.
A post-sale restraint, also termed a post-sale restriction, as those terms are used in United States patent law and antitrust law, is a limitation that operates after a sale of goods to a purchaser has occurred and purports to restrain, restrict, or limit the scope of the buyer's freedom to utilize, resell, or otherwise dispose of or take action regarding the sold goods. Such restraints have also been termed "equitable servitudes on chattels".
In re Alappat, 33 F.3d 1526, along with In re Lowry and the State Street Bank case, form an important mid-to-late-1990s trilogy of Federal Circuit opinions because in these cases, that court changed course by abandoning the Freeman-Walter-Abele Test that it had previously used to determine patent eligibility of software patents and patent applications. The result was to open a floodgate of software and business-method patent applications, many or most of which later became invalid patents as a result of Supreme Court opinions in the early part of the following century in Bilski v. Kappos and Alice v. CLS Bank.
Ariosa Diagnostics, Inc. v. Sequenom, Inc., 788 F.3d 1371, was a controversial decision of the Federal Circuit in which the court applied the Mayo v. Prometheus test to invalidate as patent-ineligible a patent said to "solve ... a very practical problem accessing fetal DNA without creating a major health risk for the unborn child." In December 2015, the Federal Circuit denied a motion for en banc rehearing, with several members of the court filing opinions urging Supreme Court review. On June 27, 2016, the Supreme Court of the United States denied Sequenom's petition for a writ of certiorari.
