I addition to You may need using Acquisition.Implicit
you might need to use aq_parent. Or remove the title method alltogether.

from Acquisition import Implicit, aq_parent

class MyAttr(Implicit):

    def title(self)
        "I need to get ie. title value from 'MyProduct'"
        return aq_parent(self).title


class MyProduct:

    my_attr = MyAttr()
