Bearing this decision in mind and the way in which the courts have chosen to deal with pharmaceutical claims, it would seem impossible to conclude that the issue of patentability is based purely on finding a 'solution for a technical problem that could not be solved before'.

Obviousness 显著性

This leads us on to consider how important the actual resulting process or invention is to the determination of whether or not it is patentable. Aside from the requirement of novelty, the process or invention must involve and innovative step. This has been interpreted to mean that the invention would not be obvious to someone skilled in the art when presented with the relevant matter. One of the ways in which this test has been interpreted is to consider whether or not it fills a gap in the market, thus becoming an immediate business success. If this is the case, it is more likely that the invention would be seen as non-obvious and, therefore, patentable.

The requirement for this inventive step is contained in Section 3 of the Act. Deciding on what exactly is obvious and what is not has been a matter for the courts. In the case of Windsurfing International Inc. v Tabur Marine (Great Britain) Ltd, the main test for obviousness was laid down and remains the starting point for judges when deciding whether or not the invention is obvious. It was held that the court should take a four stage approach. Firstly, it should look at the inventive step itself in isolation, i.e. separating it from any supplementary aspects of the invention. Secondly, once the court is clear what the inventive step in question actually is, it should put itself in the position of the common person, skilled in the relevant art with the knowledge that was available at the date of priority. Thirdly, the court needs to consider the difference between what is known by the common man and what the invention professes to display. Finally, the court needs to determine whether the step between what is known and the invention would have been obvious to the common man.

For example, in the case of Sabaf SpA v. MFI Furniture Centres Limited and others, the House of Lords considered the issue of whether the gas burner in question was obvious. In this case, the argument that Sabaf was presenting to the court was that its patent for a gas burner had been infringed. The respondents (MFI and others) claimed that they were using a new invention as it was, in fact, the combination of two inventions that had generated their specific gas burner. The crucial point here was that it was not possible to take two existing inventions and put them together to establish a new invention, where this new invention would be the obvious product of the two original inventions.

The test for being obvious seems to be reasonably wide with the court requiring a definite inventive step and not simply a natural progression, even if the natural progression is novel.

Conclusions 结论

The area of patent law and, in particular, determining whether or not an invention is novel and / or obvious is by no means clear. The courts take a very individual approach to each case as it is presented to them based on the individual facts. Despite this, it seems that both elements, i.e. novelty and obviousness, remain instrumental. It is not true to say that provided an invention is novel it does not matter wheth
