Don't essentially all modern production renderers use path tracing? Mental Ray was the last 'major' renderer I know of that used ray tracing, and it was discontinued a few years back.

Note that "path tracing" is also overloaded, some people use it to mean any ray tracing that does global illumination, but the term also refers to a stricter definition which is an algorithm that integrates lighting in n-dimensional path space. A path tracer under that latter definition doesn't do any branching along a path, instead it builds complete paths from camera to light to calculate the contribution to a pixel. This is where the name came from.
It is easier to get soft shadows and global-illumantion-like effects with a path tracer. I remember reading articles circa 2013/2014 about Pixar moving to a path-tracer, which significantly reduced the amount of time they had to spend manually tuning lights and hacking in shadow effects, etc.
