The inventive step reflects a general patentability requirement in most patent laws, according to which an invention should be sufficiently inventive (not obvious in view of the prior art using the skilled person’s common general knowledge) in order to be patented / the patent to be held valid. In the United States, rather than ‘inventive step’, the expression ‘non-obviousness’ is used: is the invention an adequate distance beyond or above the state of the art? The assessment of the inventive step varies from one country to another. The European Patent Office uses the so-called problem-and-solution approach to assess inventive step, an instrument also used by several national European courts.
The number of inventive step attacks in opposition procedures at the European Patent Office may be constrained in the future due to a recent change in the EPO Guidelines. According to David Brophy, partner at FRKelly, the change will improve efficiency, although the restrictions may also open up a new avenue for criticising decisions on…

In a case concerning two divisional patents derived from the same parent application relating to ‘transcatheter heart valves’ or THVs, which can be introduced via a blood vessel, rather than through open heart surgery, the Court held one patent invalid for lack of inventive step, though had it been valid it would have been infringed….

The reason was…
