Eligibility
(Conclusion)
The claimed invention is eligible.
In the case where a claim refers to some technical means, if the essence of a claimed invention is found to be directed to human activity itself, considering the recitation in the claim as a whole, then the claimed invention is not eligible. On the other hand, in the case where a claimed invention includes or relates to some human mental activity, if the essence of the invention is intended to provide technical means to assist or replace human mental activity, the invention should not be deemed to be ineligible.
