3 Why software?
4 Software Software is "a set of statements or instructions to be used directly or indirectly in a computer to bring about a certain result". These instructions are set out in source code, a set of in logical human-readable instructions coded into computer language. Object code is the result of a compilation of the source code into machine readable instructions.
5 Source code #!/usr/bin/perl # Public domain. Questions to Jamie McCarthy, jamie@mccarthy.vg use LWP::Simple; use Math::BigInt; my $html = get(`http://www.utm.edu/research/primes/curios/48565...29443.html'); my($prime) = $html =~ m{ ([^ }; $prime =~ tr{0-9}{}cd; $prime = Math::BigInt->new($prime); my $binary = ''; while ($prime > 0) { $binary = pack(`N', ($prime % 2**32)). $binary; $prime /= 2**32; } $binary =~ s{^\0+}{}; local *FH; open(FH, `| gunzip -acq') or die `cannot gunzip, $!'; binmode FH; print FH $binary; close FH.
10 Copyright vs Patents EXPRESSIONIDEA LITERALNON-LITERAL SYMBOLICFUNCTIONAL
11 Software Protection in Europe Software Copyright Directive 91/250/EEC requires copyright law to recognise software as a literary work. Art 52(2)(c) of the European Patent Convention states that programs for computers as such are not inventions, and therefore are not patentable.

12 Trouble with copyright: USA The idea-expression dichotomy is very well used in the United States, this has had interesting effects for software protection. look and feel cases, Apple v. Microsoft 821 F.Supp 616 (1993). Whelan Associates Inc v Jaslow Dental Laboratory Inc [1987] FSR 1 gave a test for the idea-expression dichotomy in software. Computer Associates v Altai 982 F 2d 693 (1992) – Abstraction, Filtration, Comparison.

13 Abstraction, Filtration, Comparison test Stage 1 - Abstraction - You dissect the code and isolate each level of abstraction. Stage 2 - Filtration - Examine the structured components at each level of abstraction to determine whether their inclusion at that level was idea or was dictated by efficiency, required by external factors or was taken from the public domain (and is therefore unprotectable). Stage 3 - Comparison - What remains following filtration is a core of protected expression. This must be compared for substantial similarity.

14 Trouble with copyright: UK John Richardson Computers v Flanders [1993] FSR 497. Saphena v. Allied Collection [1995] FSR 616. Ibcos Computers Ltd v Barclays Mercantile Highland Finance Ltd [1994] FSR 275. Cantor Fitzgerald International v Tradition (UK) Ltd [1999] Masons CLR 157. Navitaire Inc v easyJet Airline Co [2004] EWHC 1725 (Ch). John Richardson Computers v Flanders [1993] FSR 497. Saphena v. Allied Collection [1995] FSR 616. Ibcos Computers Ltd v Barclays Mercantile Highland Finance Ltd [1994] FSR 275. Cantor Fitzgerald International v Tradition (UK) Ltd [1999] Masons CLR 157. Navitaire Inc v easyJet Airline Co [2004] EWHC 1725 (Ch).
15 Test in Ibcos According to Jacob J, the Altai test should not be applied in the UK. What are the work or works in which the plaintiff claims copyright? Is each work 'original'? Was there copying from that work? If there was copying, has a substantial part of that work been reproduced? According to Jacob J, the Altai test should not be applied in the UK. What are the work or works in which the plaintiff claims copyright? Is each work 'original'? Was there copying from that work? If there was copying, has a substantial part of that work been reproduced?
16 Protection of functionality in Navitaire Copyright protection for computer software is a given, but I do not feel that the courts should be astute to extend that protection into a region where only the functional effects of a program are in issue. There is a respectable case for saying that copyright is not, in general, concerned with functional effects, and there is some advantage in a bright line rule protecting only the claimant's embodiment of the function in software and not some superset of that software.
17 The road towards patentability: USA The Abstraction-Filtration- Comparison test has been a failure. Owners begin to pursue other types of protection. Diamond v Diehr, 450 U.S. 175, 185 (1981) "everything under the sun that is made by man." In re Alappat, 33 F. 3d 1526 (1994), useful, concrete, and tangible result. State Street Bank v Signature Financial Group (1998) 47 USPQ2d 1596.
18 Software patents (USA, 1985- 2005)
19 But… software copyright is useful
20 Software patentability around the world Art. 27.1 TRIPS Agreement: patents shall be available for any inventions, whether products or processes, in all fields of technology. Reluctance to apply indiscriminate patentability in most regions. Art. 27.1 TRIPS Agreement: patents shall be available for any inventions, whether products or processes, in all fields of technology.

21 Patentability in Europe Strict reading of the law leads one to believe that software as such is not patentable. European Patent Office (EPO) Board of Appeals interpreted as such very broadly in several cases. 20,000 software patents approved by the EPO, 6,000 applications per year in UK.

22 Technical effect Case law has decreed that only software that has a technical effect can be patented. The term is not in the legislation, and therefore there is no clear definition of technical effect. Lack of consistency in its application. Merrill Lynch [1989] RPC 561: "There must... be some technical advance on the prior art in the form of a new result.

23 The CII Directive Technical contribution: means a contribution to the state of the art in a field of technology which is new and not obvious to a person skilled in the art. A relatively small directive proposal designed to overhaul a few technicalities in patent law and practice by harmonising the patentability of computer implemented inventions… Technical contribution: means a contribution to the state of the art in a field of technology which is new and not obvious to a person skilled in the art.

25 CII Directive
26 The aftermath Back to where we began… Case law will help to determine the definition of technical effect. New ideas have emerged in recent cases. The Commission and some sectors of the software industry will not give up. Talk of a new directive coming our way.

27 Halliburton v Smith International Two patents involved, one drill bit and software to design drill bits. In this ruling, there seems to be a clear technical effect, the software can only be used for specific purpose. The patent was struck down because it had inadequate disclosure (upheld after appeal). Could this be the strategy to attack software patents in the future? Two patents involved, one drill bit and software to design drill bits.

28 The little man test (CFPH LLC Application) The question to ask should be: is it (the artefact or process) new and non-obvious merely because there is a computer program? Or would it still be new and non-obvious in principle even if the same decisions and commands could somehow be taken and issued by a little man at a control panel, operating under the same rules? For if the answer to the latter question is 'Yes' it becomes apparent that the computer program is merely a tool, and the invention is not about computer programming at all.
29 Aerotel v Telco [...] despite the fact that such patents have been granted for some time in the US, it is far from certain that they have been what Sellars and Yeatman would have called a "Good Thing." The patent system is there to provide a research and investment incentive but it has a price. That price (what economists call "transaction costs") is paid in a host of ways: the costs of patenting, the impediment to competition, the compliance cost of ensuring non-infringement, the cost of uncertainty, litigation costs and so on. There is, so far as we know, no really hard empirical data showing that the liberalisation of what is patentable in the USA has resulted in a greater rate of innovation or investment in the excluded categories. Innovation in computer programs, for instance, proceeded at an immense speed for years before anyone thought of granting patents for them as such. There is evidence, in the shape of the mass of US litigation about the excluded categories, that they have produced much uncertainty. If the encouragement of patenting and of patent litigation as industries in themselves were a purpose of the patent system, then the case for construing the categories narrowly (and indeed for removing them) is made out. But not otherwise.
30 Microsoft v AT&T (U.S. Supreme Court) The case is whether there is patent infringement for a software product that may be sent in a master disk from the United States, and then assembled and sold abroad. AT&T owns a patent over speech-encoder software, and it sued Microsoft arguing that Microsoft Windows contains code which infringes their patent claim. AT&T included in their infringement suit international claim for all copies of Windows manufactured and sold abroad, a claim that Microsoft contended.

AT&T included in their infringement suit international claim for all copies of Windows manufactured and sold abroad, a claim that Microsoft contended. The U.S. Supreme court was asked two questions, is Windows a software component in the sense of American patent law? Here the answer was yes. If so, was the component supplied from the United States? The answer here was no, The physical master disks were shipped from places outside of the United States to overseas assembly factories, even if there was a presumption that some of the software could have been coded in the U.S.
31 Sui generis? Why not go the sui generis way? Software seems to have problems with both copyright and patents. New right that has shorter lifetime, and recognises both the literal and functional aspects of software. Why not go the sui generis way?

32 Business method patents
33 Business methods and the law Ways of doing business not traditionally covered by patent – e.g. book-keeping, sales methods, etc. State Street decision (1998), The business method exception has never been invoked by this court, or the CCPA, to deem an invention unpatentable Ex parte Lundgren (2004) USPTO Board of Patent Appeals and Interferences (BPAI). Process inventions do not have to be in the technological arts in order to be patentable in the U.S. They do, however, have to produce a "concrete, useful and tangible result".

34 State Street Bank again… State Street Bank was an example of a business method patent. The invention in State Street Bank was only possible because of computerisation – it wouldnt work without a program. Many software patents are actually business method patents where the business method is stated in program terms. Amazon.coms one click patent application is an example.

35 European situation EPC precludes support for business methods: 52(2)(c) schemes, rules and methods for performing mental acts, playing games or doing business, and programs for computers Patents were designed for industrial protection, hence this exemption.

36 Same problem for Business Methods as Software EPC precludes support for business methods: 52(2)(c) schemes, rules and methods for performing mental acts, playing games or doing business, and programs for computers Patents were designed for industrial protection, hence this exemption. However, many many patents being granted currently which look very much like business method patents.
