Infringement

All:
The query pertaining to infringement:
I gone through a US Patent claiming a process wherein a mixture of acid, phosphorous halide and a dehydrating agent is used.
Further I encounter a US application (published in 2007) claiming a process wherein phosphorous trihalide and dehydrating agent is used (acid is avoided).
There is no literal infringement however I want to know if there is an infringement under DOE? Please comments
Regards

Do the prior art and your claimed process result in the same end product?
If yes,
are both processes comparable in terms of yield, etc?
If yes,
I would say that there is infringement under DOE because the acid is an arbitrary addition to the reaction without any technical effect.

DOE CANNOT be used to eliminate an element of the claims.

While that may be true, there might be infringement nonetheless. If senior patent X claims A + B and junior patent Y claims A + B + C, chances are, the implementation of patent Y infringes patent X. No DOE required to "eliminate" anything.

Well that is obvious. I understood the question to be can patent claiming A+B+X sue someone for using A+B...then the other guy posted that maybe under DOE.
Now as I reread the question, in jumbled English it talks about patent application and patent process. So it is unclear, to me, what the question is...
