Question juridique clé
Whether the insured had a right to an AI pension for 1 October 2003 to 31 December 2009 based on his degree of invalidity.
Solution extraite
The insured could reasonably be expected to exploit a higher residual earning capacity in adapted work; the canton correctly denied a higher disability degree.
Motifs extraits
The medical evidence showed a residual work capacity above 50% in adapted work. At age 49-55, it was not unrealistic to expect a change to semi-sedentary work fitting the limitations. Personal and intellectual limitations did not make such adaptation unreasonable.
