The UK High Court has over-ruled a decision by the UK Intellectual Property Office in regards to their application for a patent for their method of indexing library functions (reports IT Pro). The UK-IPO had turned down this application, although the European Patent Office had granted it (the UK office does not recognise patents which are 'nothing more than a computer program,' where Europe does), hence their appeal to the High Court. While the case is concluded, the UK-IPO office has indicated that it will appeal the judgement.
Full Statement by the UK Intellectual Propoerty Office
A judgement in the case of Symbian's Patent Application has been issued today by the High Court overturning an earlier decision of the UK Intellectual Property Office (UK-IPO) to refuse the application because it relates to nothing more than a computer program.
Symbian's patent application describes how in a computer a library of functions (DLL), which can be called on by multiple application programs running on the computer, is accessed. In particular, it provides a way of indexing these library functions to ensure the computer will continue to operate reliably after changes are made to the library.
In his judgment Mr Justice Patten observes that the UK-IPO's decision in this case illustrates the divide which exists between the UK-IPO and the European Patent Office (EPO) about how the patentability of inventions involving computer programs is assessed. This is because although the UK-IPO refused Symbian’s patent application, the EPO has granted Symbian a patent for its invention.
The UK-IPO believes that when
deciding whether
this computer implemented invention is patentable, Mr Justice Patten did not apply the so-called "Aerotel/Macrossan test", which was established by the Court of Appeal in an earlier case 
,
in the way intended by the Court of Appeal. This in UK-IPO's view has created uncertainty about how the Aerotel/Macrossan test
should be applied for inventions of this type.
The UK-IPO will therefore appeal this judgment with a view to seeking clarification from the Court of Appeal. Pending a decision by the Court of Appeal, the UK-IPO will be continuing to follow the practice, set out in its Practice Notices issued in November 2006 and February 2008, which are founded on the established Aerotel /Macrossan test. When applying this test, the UK-IPO will take account of the Symbian judgment in appropriate cases.
