DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Application Status
This office action is responsive to the amendments filed on 10/21/2025.
The objection to the specification is withdrawn in view of the Applicant’s amendments.
In light of the Applicant’s remarks, this action has been made NON-FINAL.
Information Disclosure Statement
The information disclosure statement (IDS) submitted on 10/21/2025 is being considered by the examiner. A signed IDS is hereby attached.
Response to Arguments
Applicant's arguments filed 10/21/2025 have been fully considered but they are not persuasive.
The Applicant alleged the following: “Bojarski's markers are similar to the optical marker in claim 1 but are not similar to or the same as an image visible marker that can be captured in an image data set by a medical imaging device.”. The examiner is not persuaded. The examiner asserts the combination of Bojarski and Chopra discloses the Applicant’s claim language. More specifically, Chopra teachings of radiopaque markers in Paragraphs 0093 & 0100 discloses the Applicant’s claim language of “an image visible marker that can be captured in an image data set by a medical imaging device”. Accordingly, the examiner maintains the rejection.
The Applicant alleged the following: “However, the fiducial markers of Bojarski are not image visible markers. Image visible markers are defined in the specification of the present application, at least in part as: "The two-part device may include an image visible marker that is detectable by a medical imaging device. The two-part device may be placed on a person when a medical imaging device is used to capture a medical image (e.g., a CT (computed tomography) scan, MRI (magnetic resonance imaging) scan or X-ray) of the person." See paragraph [0013] of the present specification. Because the markers in Bojarski cited by the Office Action are not the same as the image visible marker claimed, claims 1 - 24 should be allowed”. The examiner is not persuaded. As noted above, the examiner asserts the combination of Bojarski and Chopra discloses the Applicant’s claim language. More specifically, Chopra teachings of radiopaque markers in Paragraphs 0093 & 0100 discloses the Applicant’s claim language of “an image visible marker that can be captured in an image data set by a medical imaging device”. As shown below, the examiner has provided an illustration.

Accordingly, the examiner maintains the rejection.
The Applicant alleged the following: “However, a male piece with a marker that is connected to a female piece connected to the HMD or surgical helmet does not teach or suggest that a common connector removably joins an optical marker to an image visible marker. Furthermore, the cited portions of Bojarski do not teach an image visible marker and cannot anticipate claim 1. Instead Bojarski, teaches magnets or a male/female connector to attach a marker to a helmet”. The examiner is not persuaded. The examiner asserts the combination of Bojarski and Chopra discloses the Applicant’s claim language. More specifically, Bojarski teachings of “connected or linked to the marker, the base of the marker or a holding member connected to the marker” in Column 59, Lines 20-35 & Column 59, Lines 60-67 & Column 60, Lines 1-17 correlates to the Applicant’s broad claim language of “a common connector.” Moreover, the combination of Bojarski and Chopra goes on to discloses image visible marker in Chopra Paragraphs 0093 & 0100. Accordingly, the examiner maintains the rejection.
The Applicant alleged the following: “Claim 1 also recites "a common connector to removably join the image visible marker to the optical marker and to define a fixed distance between the image visible marker and the optical marker". However, the Bojarski reference fails to disclose a common connector that defines a fixed distance between the image visible marker and the optical marker”. The examiner is not persuaded. The examiner asserts the combination of Bojarski and Chopra discloses the Applicant’s claim language. More specifically, Bojarski teachings of “connected or linked to the marker, the base of the marker or a holding member connected to the marker” in Column 59, Lines 20-35 & Column 59, Lines 60-67 & Column 60, Lines 1-17 correlates to the Applicant’s broad claim language of “a common connector.” Moreover, the combination of Bojarski and Chopra goes on to discloses image visible marker in Chopra Paragraph 0093. Additionally, Chopra’s teachings of “In addition to the coordinate position of the various P and E markers, there can be a fixed linear distance between various elements, such as the distance between the center of P.sub.1 and P.sub.0 284, the distance between P.sub.0 and the edge of the fiducial marker 286, or the distance between P.sub.2 and the edge of the fiducial marker 282. It can be appreciated that any distance between any two points can be used” in Paragraphs 0093 & 0100 correlates to the Applicant’s claim language of “and to define a fixed distance between the image visible marker and the optical marker.” Accordingly, the examiner maintains the rejection.
The Applicant alleged the following: “The common connector may define a direction and/or a fixed distance between the optical marker and the image visible marker." The prior art of Bojarski does not allow for this type of improved functionality.”. The examiner is not persuaded. As noted above, the examiner asserts the combination of Bojarski and Chopra discloses the Applicant’s claim language. More specifically, Bojarski teachings of “connected or linked to the marker, the base of the marker or a holding member connected to the marker” in Column 59, Lines 20-35 & Column 59, Lines 60-67 & Column 60, Lines 1-17 correlates to the Applicant’s broad claim language of “a common connector.” Moreover, the combination of Bojarski and Chopra goes on to discloses image visible marker in Chopra Paragraph 0093. Additionally, Chopra’s teachings of “In addition to the coordinate position of the various P and E markers, there can be a fixed linear distance between various elements, such as the distance between the center of P.sub.1 and P.sub.0 284, the distance between P.sub.0 and the edge of the fiducial marker 286, or the distance between P.sub.2 and the edge of the fiducial marker 282. It can be appreciated that any distance between any two points can be used” in Paragraphs 0093 & 0100 correlates to the Applicant’s claim language of “and to define a fixed distance between the image visible marker and the optical marker.” MPEP § 2106 states Office personnel are to give claims their broadest reasonable interpretation in light of the supporting disclosure. In re Morris, 127 F.3d 1048, 1054-55, 44 USPQ2d 1023, 1027-28 (Fed Cir. 1997). Accordingly, the examiner maintains the rejection.
Claim Rejections - 35 USC § 103
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) 1-24 are is/are rejected under 35 U.S.C. 103 as being unpatentable over Bojarski, US Patent No.:11,857,378 in view of Chopra, US20220008141.
Claim 1:
Bojarski discloses a device to enable alignment of an image data set with an anatomy of a person using an augmented reality (AR) headset (See Bojarski Abstract & Figure 1; Figures 4A-4C & Column 10, Lines 35-50) but failed to explicitly disclose the following:
“an image visible marker that is detectable by a medical imaging device” and “to define a fixed distance between the image visible marker”. Chopra discloses the Applicant’s claim language of “an image visible marker that is detectable by a medical imaging device” in Paragraph 0093. Moreover, Chopra discloses the Applicant’s claim language of “to define a fixed distance between the image visible marker” in Paragraph 0100. It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to have further modified Bojarski by the teachings of Chopra to produce visual image data set from a visual image sensor containing at least one visual marker, more effectively (See Chopra Summary of the Disclosure section). In addition, both references teach features that are directed to analogous art and they are directed to the same field of endeavor, such as, incorporating augmented reality (AR) technology with medical devices.
