it is about use of "that of " in comparision sentences
I have run into the following questions. Thanks for anyone in advance for any fix
Q 1
"The present invention has any advantageous effect different from that of demonstrated invention."
My question is "should the use of that in the above be considered incorrect grammatically" So, the above sentence should be rendered like this " The present invention has any advantageous effect different from the demonstrated invention."
Q 2
Likewise,
" There has been no constitutional difficulty or advantageous effect therefrom different from that of another demonstrated invention."
In the same vein as under Q 1, should the use of "that of" in the above be considered grammtically incorrect. I am a little unsure whether the above sentence is grammtically correct or not. Should the above sentnece be rendered as " There has been no constitutional difficulty or advantageous effect therefrom different from another demonstrated invention."
Q 3
" The invention of Claim 1 is obvious over D1 (another demonstrated invention) for the same reason as set forth under Reason A. Should this sentence be changed to "the invention of Claim 1 is obvious over that of D1." When comparison is made between the invention of Claim 1 and invention arising from D1.
And also I am wondering about what your impression of the "the invention of Claim 1 is obvious over D1 (another demonstrated invention) when you first look at this sentence. What your impression or your instant interpretation of this given sentence above when you first look at it or after some pausing moments to look at it.
Thanks for your answers and time in advance

I gues the meaning of all original sentences is as follows.
you can substitute a quoted invention for the demonstrated invention. Then, all the sentences may make sense.
All the three sentences ask you of whether you should include "that" or discard "that" when comparing two inventions where one invention has an advantageous effect such as efficiey is vastly increased or s
