Recent trends regarding successful Patent Attorney exam candidates

Half of this year's successful candidates are women (around 49%?)
Out of 200 people, about 100 are women.
In the past, the percentage of female successful candidates was around 20-30%.

so it is quite surprising that there are so many female successful candidates.
It seems like it has become a fallback career for female engineering students.

as there aren't many of them here.
It is mostly crowded with people from Chemistry and Bio fields.
Even though what the industry actually needs is Electrical and Electronic Engineering.
