France

On January 7, 1791, France passed a patent law that stated that "Any new discovery or invention, in all types of industry, is owned by its author...". Inventors paid a fee depending upon the desired term of the patent (5, 10, 15 years), filed a description of the invention and were granted a patent. There was no preexamination. Validity was determined in courts. 14 out of 48 of the initial patents were for financial inventions. In June of 1792, for example, a patent was issued to inventor F. P. Dousset for a type of tontine
Tontine
A tontine is an investment scheme for raising capital, devised in the 17th century and relatively widespread in the 18th and 19th. It combines features of a group annuity and a lottery. Each subscriber pays an agreed sum into the fund, and thereafter receives an annuity. As members die, their...

. These patents raised concerns and were banned and declared invalid in an amendment to the law passed in 1792.

Britain

In Britain, a patent was issued in 1778 to John Knox for a “[p]lan for assurances on lives of persons from 10 to 80 years of age.” At this time in British law, patents could only be issued for manufactured objects, not manufacturing processes.

United States

Patents have been granted in the United States on methods for doing business since the US patent system was established in 1790. The first financial patent was granted on March 19, 1799, to Jacob Perkins of Massachusetts for an invention for "Detecting Counterfeit Notes." All details of Mr. Perkins invention, which presumably was a device or process in the printing art, were lost in the great Patent Office fire of 1836. Its existence is only known from other sources.

The first financial patent for which any detailed written description survives was to a printing method entitled "A Mode of Preventing Counterfeiting" granted to John Kneass on April 28, 1815. The first fifty years of the U.S. Patent Office saw the granting of forty-one financial patents in the arts of bank notes (2 patents), bills of credit (1), bills of exchange (1), check blanks (4); detecting and preventing counterfeiting (10), coin counting (1), interest calculation tables (5), and lotteries (17).

On the other hand, cases such as Hotel Security Checking Co. v. Lorraine Co., 160 F. 467 (2d Cir. 1908), which held that a bookkeeping system to prevent embezzlement by waiters was unpatentable, were often read to imply a "business method exception", in which business methods are unpatentable. Another such case was Joseph E. Seagram & Sons v. Marzell, 180 F.2d 26 (D.C. Cir. 1950), in which the court held that a patent on “blind testing” whiskey blends for consumer preferences would be “a serious restraint upon the advance of science and industry” and therefore should be refused.

For many years, the USPTO took the position that "methods of doing business" were not patentable. With the emergence in the 1980 and 1990s of patent applications on internet or computer enabled methods of doing commerce, however, USPTO found that it was no longer practical to determine if a particular computer implemented invention was a technological invention or a business invention. Consequently they took the position that examiners would not have to determine if a claimed invention was a method of doing business or not. They would determine patentability based on the same statutory requirements as any other invention.

The subsequent allowance of patents on computer implemented methods for doing business was challenged in the 1998 State Street Bank v. Signature Financial Group, (47 USPQ

, (50 USPQ 2d 1447 (Fed. Cir. 1999)).

The USPTO continued to require, however, that business method inventions must apply, involve, use or advance the "technological arts" in order to be patentable. This was based on an unpublished decision of the U.S. Board of Patent Appeals and Interferences

In October 2005 the USPTO's own administrative judges overturned this position in a majority decision of the board in Ex Parte Lundgren
Ex Parte Lundgren

, Appeal No. 2003-2088 (BPAI 2005). The board ruled that the "technological arts" requirement could not be sustained, as no such requirement existed in law.

In light of Ex Parte Lundgren, the USPTO has issued interim guidelines for patent examiners to determine if a given claimed invention meets the statutory requirements of being a process, manufacture, composition of matter or machine (35 USC 101). These guidelines assert that a process, including a process for doing business, must produce a concrete, useful and tangible result in order to be patentable. It does not matter if the process is within the traditional technological arts or not. A price for a financial product, for example, is considered to be a concrete useful and tangible result (see State Street Bank v. Signature Financial Group).

The USPTO has reasserted its position that literary works, compositions of music, compilations of data, legal documents (such as insurance policies

), and forms of energy (such as data packets transmitted over the Internet), are not considered "manufactures" and hence, by themselves, are not patentable. Nonetheless, the USPTO has requested comments from the public on this position.

There has been considerable speculation as to how this opinion might affect future business method patent litigation, particularly where a patent owner seeks an injunction to stop an infringer. In 2006, three Justices (Breyer, J., joined by Stevens and Souter, JJ.) dissented from the dismissal of certiorari as improvidently granted in Laboratory Corp. of Am. Holdings v. Metabolite Labs., Inc., arguing that State Street enunciated an erroneous legal test under which processes that the Supreme Court had held patent-ineligible would be held patent-eligible.

. The decision appears to hold patent-ineligible many business-method patents granted in the last decade. Bilski announces a two-branch test of patent-eligibility for processes. First, processes that transform an article from one state or thing to another are patent-eligible regardless of whether their use requires a machine. What is an article, however, is debatable. The transformations involved in smelting ores or vulcanizing rubber are clearly patent-eligible. Thus, substances such as ores and rubber, are articles. Processes involving transformation of signals representative of physical parameters may also be patent-eligible. Processes involving transformation of financial data, such as that claimed in machine format in State Street, are probably patent-ineligible. Second, processes that do not make patent-eligible transformations are patent-eligible only if they are claimed as carried out with a “particular machine.” What is a particular machine is unclear. It appears that a programmed general-purpose digital computer is not a particular machine, for this purpose. It is unclear whether a particular machine must be novel and unobvious, and specially adapted for carrying out the new process. The Supreme Court’s decision in Parker v. Flook
Parker v. Flook
Parker v. Flook, 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 the implementation is novel and unobvious.

seems to call for that, but the Bilski court did not choose to opine on this point.

Australia

There is no general prohibition on the patentability of business methods in Australia. Their patentability is determined by applying the tests used to determine the patentability of any type of invention.

In a recent decision, Grant v Commissioner of Patents [2006] FCAFC 120, [47], the Full Court of the Federal Court of Australia held that a business method will only be patentable if it has a physical aspect, being a concrete, tangible, physical, or observable effect or phenomenon. Accordingly, 'pure' business methods, being those that do not have a physical aspect, are not patentable in Australia.

However, it has been suggested that Grant v Commissioner of Patents was wrongly decided because the court failed to properly apply the existing law as set out in the decision of the High Court of Australia in National Research Development Corporation v Commissioner of Patents (1959) 102 CLR 252 and that the court should not have imposed a physical aspect requirement.

Canada

Pure business methods cannot be patented in Canada because of its pre-constitutional (in 1982) subordination to British Common Law. Article 1(2)(c) of the Patent Law of 1977 “It is hereby declared that the following (among other things) are not inventions for the purposes of this Act, that is to say, anything which consists of …. a scheme, rule or method for performing a mental act, playing a game or doing business, or a program for a computer.” For example, the Canadian counterpart application of the U.S. patent at issue in the State Street case has been abandoned.

However, a business method patent may be patented in Canada if the patent is claimed in a manner which provides that an apparatus is involved. See Mark B Eisen, Arts and Crafts: The Patentability of Business Methods in Canada (2001), 17 C.I.P.R. 279. See also Amazon.com, Inc. v The Attorney General of Canada, 2010 FC 1011, October 14, 2010

Brazil

According to Brazilian Patent Law 9279, "commercial, accounting, financial, educational, advertising, raffling, and inspection schemes, plans, principles or methods" are not considered to be inventions or Utility Models.

India

Per Section 3(k), business methods are not patentable per se. However they are patentable if a new method solves a "technical" problem and an apparatus/system is involved.

Japan

In Japan, business methods are well recognized and accepted as patentable subject matter. The legal standard used to assess whether a business method is patentable requires that inventions be "a highly advanced creation of technical ideas by which a law of nature is utilized."

Patents are not issued solely for business methods. The business method must contain a technical aspect that is both tangible and real.

However this requirement may be satisfied simply by specifying that the method is implemented using a computer.

United States

There is no exclusion for methods of doing business under US patent law. Patent applications for methods of doing business are examined using the same standards as any other invention.

) requires that a method for doing business must be tied to a particular machine (e.g. computer) or transform matter. This case law, however, is under review by the US Supreme Court.

 on June 28, 2010 ruled that Bilski's patent was not valid. However, the decision was widely criticized for resolving the immediate problem with Bilski's business method patent while offering little guidance on the actual issue of business method patentability. Ultimately, the court rejected the more 'bright-line' test proposed by the federal circuit as too rigid and resolved the question by restating the statutes broad goals. Therefore, business methods continue to be patentable subject matter; however, the question remains as to how exactly to decide that patentability.

On average, the USPTO will issue 20 rejections for every allowance. Patent applications in more conventional technologies, such as electrical connector

Delays in examination

The USPTO is experiencing significant delays in examining business method patents. Projected delays of up to 14 years have been reported. The delays are due to a combination of the step change in business method filings as of the State Street Bank decision and the difficulty in hiring qualified examiners with financial services backgrounds (e.g. insurance and banking). It has also been reported, however, that inventors can get their patent applications examined in as little as six months, if they submit a Petition to make special
