Claims 1-20 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention.
Regarding claims 1, 8 and 16, the claim limitation “reduction in maximum transvalvular flow” in claims 1, 8 and 16 was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention.

Regarding claim 19, Burwash, Fortuin, Nystrom, and Ben-Dor disclose the invention substantially described the 103 invention above, furthermore, Burwash shows positioning a non-invasive imaging system for cardiac imaging (see “method” on page 1343, and “results” on page 1344); and acquiring the baseline measurements and the additional measurements using the non invasive imaging system (see “method” on page 1343, and “results” on page 1344), but fails to explicitly state transthoracic echocardiogram.
Mansi teaches using transthoracic echocardiogram. Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing of the claimed invention, to have utilized the teaching of transthoracic echocardiogram in the invention of Burwash, Fortuin, Nystrom, and Ben-Dor, as taught by Mansi, to be able to provide a in depth 3D or 4D image of the heart.

Applicant’s arguments filed on 07/24/2025 with respect to prior art rejection have been considered but are moot because the new ground of rejection does not rely on any rejection applied in the prior office action of record for any teaching or matter specifically challenged in the argument. The examiner has provided new prior art Nystrom for independent claims 1, 8 and 16.
