Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 10 is rejected under 35 U.S.C. 103 as being unpatentable over Li et al (Pub. No.: US
2020/0226422) in view of in view of Dascal et al (Pub. No.: US 2014/0270436).
Regarding claim 10, Li et al disclose one or more depictions an atherectomy device size [see
0189].
Li et al don't disclose a rotational atherectomy device.
Nonetheless, Dascal et al disclose a rotational atherectomy device [see 0173].
Therefore, it is obvious to one skilled in the art at time the invention was filed and would have
been motivated to combine Li et al and Dascal et al by using a rotational atherectomy device size; It
prepares the artery for optimal stent expansion by removing rigid calcium deposits; It helps restore
circulation in cases where traditional balloon angioplasty alone would be ineffective and it reduces the
risk of arterial damage during stent placement.
Claim(s) 11-12 are rejected under 35 U.S.C. 103 as being unpatentable over Liet al (Pub. No.: US
2020/0226422) in view of Chao et al (Pub. No.: US 2020/0129158).
Regarding claims 11-12, Li et al disclose a plurality of panels corresponding to different time
periods during an intervention [see 0152, 0154] by disclosing the data collection system 40 and the
angiography system 20 have a shared clock or other timing signals configured to synchronize angiography video frame time stamps and OCT image frame time stamps [see 0086] and the BPT time
ranges from greater than 0 to about 60 seconds. In one embodiment, the BPT time is less than about
180 seconds [see 0152, 0154]
Li et al don't disclose wherein the plurality of panels includes a pre-treatment panel, a lesion
prep panel, and a post-treatment panel.
Nonetheless, Chao et al disclose a pre-treatment panel, a lesion prep panel, and a post-
treatment panel [see 0037, 0074-0077].
Therefore, it is obvious to one skilled in the art at the time the invention was filed and would
have been motivated to combine Li et al and Chao et al by using a pre-treatment panel, a lesion prep
panel, and a post-treatment panel; to increase visualization.
Response to Arguments
Applicant's arguments filed 4/28/26 have been fully considered but they are not persuasive.
The double patenting rejections are moot due to the approved disclaimer.
Applicant argues claim 1 is amended to recite that one or more reference indicators are disposed along the calcium map, the one or more reference indicators being user-manipulatable. Li does not appear to teach or suggest these limitations. For example, Li does not appear to teach or suggest reference indicators disposed on a calcium map.
The examiner disagrees because Li et al disclose one or more reference indicators are disposed along the calcium map, the one or more reference indicators (color indicia) being user-manipulatable [see 0105, 0121].
