Software that allows programmers to program a mobile phone system remotely from a computer can be patented because it is more than just a software program, the Intellectual Property Office (IPO) has decided. The decision related to whether UK patent application number GB0424655.9 in the name of Nokia Corporation (Nokia) was excluded from being patented under s.1(2) of the Patents Act 1977 (the Patents Act)1.

The Patents Act says that something cannot be patented if it consists only of a program for a computer. The IPO has historically been quite strict in denying patents for “pure” software. In contrast, the US allows software to be patented.

This means that UK software developers have been left to rely on copyright to protect their work. Copyright only offers protection against being copied. Patents, on the other hand, are an absolute right against unauthorised use of the patent holder’s invention, and can protect the underlying ideas or processes. So with a patent, it does not matter whether a competitor has copied the program or developed an identical program – or indeed a different program which uses the same ideas or process steps – on their own, it still breaches the patent and the patent holder can claim damages and/or an injunction to enforce their rights.

The patent application, for programming mobile phones remotely, was first applied for by Intuwave, then passed to Symbian and finally to Nokia, which appealed an initial IPO decision to refuse it.

The invention allows a computer to control a mobile phone while software was being developed, which Nokia said was an improvement over using the mobile phone’s controls to develop software and using a computer emulator of the phone, which were the methods used until now for development.

Andrew Bartlett, deputy director of the IPO, upheld Nokia’s appeal and allowed the patent to be registered because the invention made a “technical contribution” when compared with current technology in the field (the so called “prior art”).

Mr Bartlett’s decision comes in the light of two recent landmark Court of Appeal decisions on software patentability. In a case involving Aerotel and Macrossan, the court set out a four-step test to assess whether something fell outside the scope of patentability1.

The test consists of: (i) interpreting the invention claim properly; (ii) identifying the actual contribution the invention makes; (iii) considering whether that contribution falls solely within matters that can not be patented by law (the so-called “excluded categories” of which inventions which are simply computer programs are one); and (iv) checking whether that contribution is technical in nature.

The court in this case then applied that four-step test to medical ordering software developed by mobile phone software company Symbian. The court reversed the IPO’s refusal of a patent because the technology was found to have made a technical contribution. The court decided that the invention was not just a better computer program but it also turned the machine it ran into “a better and faster computer”. It therefore made a technical contribution.

In his Nokia decision, Mr Bartlett said “In my view, the particular way that [this] invention overcomes the technical problems inherent in the prior art provides a technical contribution. Thus whilst the invention may be implemented in software it provides a technical contribution such that it is more than a program for a computer as such.”

This latest whittling down of the general rule against patenting of software is important for software developers to bear in mind. If they can demonstrate that their software is more than just a clever bit of programming but that it also produces a technical effect, then applications for a patent will receive a more favourable response than before.

This perhaps reflects an increasingly widely promoted view that there is no economic evidence to show that patent protection for computer software has any benefit in innovation.
