DETAILED ACTION
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 101
35 U.S.C. 101 reads as follows:
Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
Claims 1-10 and 13-21 are rejected under 35 U.S.C. 101 because the claimed invention is directed to
abstract idea without significantly more.
Step 1
Claims 1-10 and 13-21 are within the four statutory categories. However, as will be shown below, claims 1-10 and 13-21 are nonetheless unpatentable under 35 U.S.C. 101.
Claim 1 is representative of the inventive concept and recites:
A surgical system, comprising:
at least one computing device, comprising:
processing circuitry;
and a memory coupled to the processing circuitry, the memory storing data associated with a patient, and an implant model having an interface element, the interface element comprising an intramedullary (IM) stem, the memory comprising instructions that, when executed by the processing circuitry, may cause the processing circuitry to:
map a three-dimensional (3D) volume of an IM canal, associated with a target bone, using one or more optically tracked point probe measurements, wherein a mapped 3D volume of the IM canal corresponds to a 3D virtual interface region for a virtual model of the target bone, operative to engage the interface element of the implant model;
generate, based on at least the data associated with the mapped 3D volume of the IM canal, a modified three-dimensional (3D) virtual interface region for the virtual model of the target bone, wherein the generation of the modified 3D virtual interface region comprises:
defining a 3D constraint space within the mapped 3D volume of the IM canal based on one or more of patient anatomy features and implant model parameters;
modifying the 3D virtual interface region by including the 3D constraint space, as a virtual feature, within the 3D virtual interface region associated with the mapped 3D volume of the IM canal the 3D constraint space being operative to confine a movement of the interface element, associated with the implant model, within the 3D volume of the IM canal associated with the modified 3D virtual interface region, in accordance to at least one valid configuration for fitting the interface element of the implant model within the modified 3D interface region of the virtual model of the target bone;
and overlaying one or more placement validity indicators, as dynamic graphical objects, onto one or more portions of the 3D constraint space associated with the modified 3D virtual interface region.
Step 2A Prong One
The broadest reasonable interpretation of these steps includes mental processes because the
highlighted components can practically be performed by the human mind (in this case, the process of mapping, generating, defining, and modifying) or using pen and paper. Other than reciting generic computer components/functions such as “system”, “computing device”, “processing circuitry”, and “memory coupled to the processing circuitry”, nothing in the claims precludes the highlighted portions from practically being performed in the mind. For example, in claim 1, but for the generic computer language, the claim encompasses the user determining a plan and following the plan for a medical procedure. If a claim limitation, under its broadest reasonable interpretation, cover performance of the limitation in the mind but for the recitation of generic computer components/functions, then it falls within “Mental Processes” grouping of abstract ideas. Additionally, the mere nominal recitation of a generic computer does not take the claim limitation out of the mental process grouping. Thus, the claim recites a mental process. The highlighted portion, specifically the model, under its broadest reasonable interpretation can also fall under “Mathematical concepts” because the model relates to mathematical relationships, mathematical formulas or equations, mathematical calculations. MPEP § 2106.04(a)(2)(I). The types of identified abstract ideas are considered together as a single abstract idea for analysis purposes.
Step 2A Prong Two
This judicial exception is not integrated into a practical application. In particular, the claims recite the
following additional limitations:
Claim 1 recites: “system”, “computing device”, “processing circuitry”, “memory coupled to the processing circuitry”, “model”, and “virtual”.
In particular, the additional elements do not integrate the abstract idea into a practical application, other than the abstract idea per se, because the additional elements amount to no more than limitations which:
Amount to mere instructions to apply an exception (MPEP 2106.05(f)). The limitations
are recited as being performed by a “system”, “computing device”, “processing circuitry”, “memory coupled to the processing circuitry”, and “model”. A computer is recited at a high level of generality and amounts to no more than mere instructions to apply the exception using a generic computer.
Add insignificant extra-solution activity (MPEP 2106.05(g)) to the abstract idea such as the
recitation of “virtual”.
Dependent claims 4, 6, 7, 9, 10, 13, 14, 16-20 recite model
Dependent claims 9 and 10 recite device
Dependent claim 19 recites GUI
Dependent claim 21 recites transmitted and stored
In particular, the additional elements do not integrate the abstract idea into a practical application, other than the abstract idea per se, because the additional elements amount to no more than limitations which:
Amount to mere instructions to apply an exception (MPEP 2106.05(f)). The limitations
are recited as being performed by a “device” and “model”. A computer is recited at a high level of generality and amounts to no more than mere instructions to apply the exception using a generic computer.
Add insignificant extra-solution activity (MPEP 2106.05(g)) to the abstract idea such as the
recitation of “GUI”, “transmitted”, and “stored”.
Dependent claims 2, 3, 5, 8, and 15 do not include any additional elements beyond those already recited in independent claim 1 or dependent claims 4, 6, 7, 9, 10, 13-14, and 16-20, hence do not integrate the aforementioned abstract idea into a practical application. Looking at the limitations as an ordered combination adds nothing that is not already present when looking at the elements taken individually. There is no indication that the combination of elements improves the functioning of a computer or any other technology. Their collective function merely provides conventional computer implementation and do not impose a meaningful limit to integrate the abstract idea into a practical application.
Step 2B
Claim 1 does not include additional elements that are sufficient to amount to significantly
more than the judicial exception. As discussed above with respect to discussion of integration of the
abstract idea into a practical application, the additional elements: A system in claim 1; amount to no
more than mere instructions to apply an exception to the abstract idea. Additionally, the additional
limitations, other than the abstract idea per se amount to no more than limitations which amount to
elements that have been recognized as well-understood, routine, and conventional activity in particular
fields as demonstrated by the recitation of an additional element such as:
Virtual, which expressly means to be carried out, accessed, or stored by means of a computer (Para 0071, Levendowski(US-20180333558-A1) discloses: “Such methods may include augmented reality (e.g., overlaying any of the visual elements described herein over a real-time image of the user's physical environment), virtual reality (e.g., providing a virtual universe in which the user can move and with which the user can interact using conventional virtual reality gear, such as a headset, hand paddles, etc.), and/or the like.”) in a manner that is well-understood, routine, and conventional.
Graphical user interface (GUI)/UI, which refers to a visual way of interacting with a computer (Para 0040, Mann(US 20180357914 A1) discloses: “A conventional GUI display includes a desktop metaphor upon which one or more icons, application windows, or other graphical objects are displayed.”) in a manner that is well-understood, routine, and conventional.
Transmitted, which refers to the process of sending digital information between devices over a communication channel using a signal (TLI Communications LLC v. AV Auto. LLC, 823 F.3d 607, 614, 118 USPQ2d 1744, 1748 (Fed. Cir. 2016)) in a manner that is well-understood, routine, and conventional.
Storing, which refers to the process of recording digital information on physical or virtual media (Versata Dev. Group, Inc. v. SAP Am., Inc., 793 F.3d 1306, 1334, 115 USPQ2d 1681, 1701 (Fed. Cir. 2015) in a manner that is well-understood, routine, and conventional.
Dependent claims 2, 3, 5, 8, and 15 do not include any additional elements beyond those already
addressed above for independent claim 1 or dependent claims 4, 6, 7, 9, 10, 13-14, and 16-20. Therefore, they are not deemed to be significantly more than the abstract idea because, as stated above, the limitations of the aforementioned dependent claims amount to no more than generally linking the abstract idea to a particular technological environment or field of use, and/or do not recite and additional elements not already recited in independent claim 1, hence does not amount to “significantly more” than the abstract idea. Thus, taken alone, the additional elements do not amount to significantly more than the abstract idea identified above. Furthermore, looking at the limitations as an ordered combination adds nothing that is not already present when looking at the elements taken individually, and there is no indication that the combination of elements improves the functioning of a computer or improves any other technology, and their collective function merely provide conventional computer implementation.
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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claims 1-6, 8-9, 10, and 13-19 are rejected under 35 U.S.C. 103 as being unpatentable over Otto(WO2010068212A1) in view of Couture(US20150347710A1) and Bellettre(US20190117311A1).

3D volume of the IM canal associated with the modified 3D virtual interface region(Figure 6, Couture discloses what can be considered an interface region of the IM canal of target bone that would interface with the implant)
Before the effective filing date of the claimed invention, it would have been obvious to one of
ordinary skill in the art to have modified the implant planning for multiple implant components using constraints of Otto to add:
the interface element comprising an intramedullary (IM) stem

as taught by Couture. One of ordinary skill would have been so motivated to define a region where an implant and the patient anatomy interact, to better enable patient outcomes for surgical procedures, but in this case, for a patient-specific cutting block and manufacturing method (Para 0004, Couture discloses: “The pre-operative planning may help in ensuring the precision and accuracy of the surgery, as bone alterations will influence the fit of the implant onto the bone. For example, a bone that has been improperly cut may lead to improper implant placement, resulting in conditions such as leg length discrepancy, improper gait, premature implant wear, and pain, to name a few.”).

ordinary skill in the art to have modified the implant planning for multiple implant components using constraints of Otto to add overlaying one or more placement validity indicators, as dynamic graphical objects, onto one or more portions of the 3D constraint space associated with the modified 3D virtual interface region, as taught by Bellettre. One of ordinary skill would have been so motivated to be able to provide visual indication of placement according to a surgical plan to improve patient outcomes, but in this case, for implant planning (Para 0008, Bellettre discloses: “a need exists for surgical methods and devices which can overcome the aforementioned problems so as to enable intraoperative implant planning for accurate placement and implantation of multiple joint implant components providing improved joint performance; consistent, predictable operative results regardless of surgical skill level; sparing healthy bone in minimally invasive surgery; achieving a fit of the implant components that address each patient's unique anatomy, ligament stability, and kinematics; and reducing the need for replacement and revision surgery.”).

Before the effective filing date of the claimed invention, it would have been obvious to one of
ordinary skill in the art to have modified the implant planning for multiple implant components using constraints of Otto to add modified 3D virtual interface region for engaging the interface element of the implant model as taught by Couture. One of ordinary skill would have been so motivated to define a region where an implant and the patient anatomy interact, to better enable patient outcomes for surgical procedures, but in this case, for a patient-specific cutting block and manufacturing method (Para 0004, Couture discloses: “The pre-operative planning may help in ensuring the precision and accuracy of the surgery, as bone alterations will influence the fit of the implant onto the bone. For example, a bone that has been improperly cut may lead to improper implant placement, resulting in conditions such as leg length discrepancy, improper gait, premature implant wear, and pain, to name a few.”).

ordinary skill in the art to have modified the implant planning for multiple implant components using constraints of Otto to add automatically update the one or more validity indicators in real time and to distinguish valid and invalid positions, as taught by Bellettre. One of ordinary skill would have been so motivated to be able to provide visual indication of placement according to a surgical plan to improve patient outcomes, but in this case, for implant planning (Para 0008, Bellettre discloses: “a need exists for surgical methods and devices which can overcome the aforementioned problems so as to enable intraoperative implant planning for accurate placement and implantation of multiple joint implant components providing improved joint performance; consistent, predictable operative results regardless of surgical skill level; sparing healthy bone in minimally invasive surgery; achieving a fit of the implant components that address each patient's unique anatomy, ligament stability, and kinematics; and reducing the need for replacement and revision surgery.”).

Stein discloses:
responsive to one or more placement inputs received from one or more of a user and a tracked surgical instrument(Figure 5, Stein discloses a tracked surgical instrument)

ordinary skill in the art to have modified the implant planning for multiple implant components using constraints of Otto to add responsive to one or more placement inputs received from one or more of a user and a tracked surgical instrument, as taught by Stein. One of ordinary skill would have been so motivated to be able to track implant placement according to a surgical plan to improve patient outcomes, but in this case, for a GUI used for orthopedic tool position and trajectory(Para 0005, Stein discloses: “Even with templating, trialing, and advanced prosthetic components, outcomes including functional efficacy, patient comfort, and longevity of the prosthesis may not always be highly predictable, especially if procedures are performed by physicians and surgeons with different levels of skill, experience, and frequency of repeating an individual procedure.”).
Claim 7 is rejected under 35 U.S.C. 103 as being unpatentable over Otto(WO2010068212A1) in view of Couture(US20150347710A1), Bellettre(US20190117311A1), and Metzger(US20100087829A1).

Before the effective filing date of the claimed invention, it would have been obvious to one of
ordinary skill in the art to have modified the implant planning for multiple implant components using constraints of Otto to add to generate a surgical plan determined based on a configuration of the implant model within the constraint model, as taught by Metzger. One of ordinary skill would have been so motivated to be able to automatically determine an accurate surgical plan using an existing constraint model of a patient, but in this case, for a patient-specific knee alignment guide (Para 0002, Metzger discloses: “Proper alignment of prosthetic components in knee arthroscopy is an important factor in the longevity and function of the implant. Misalignment can cause increased wear of the implant, patient discomfort, and functional limitation.”).
Claim 21 is rejected under 35 U.S.C. 103 as being unpatentable over Otto(WO2010068212A1) in view of Couture(US20150347710A1), Bellettre(US20190117311A1), Metzger(US20100087829A1), and Haddad(US8265949B2).
Claim 21
Otto, Couture, Bellettre, and Metzger, do not explicitly disclose:
The surgical system of claim 7, wherein the surgical plan is stored and transmitted for execution by a computer-assisted surgical system.
Haddad discloses:
The surgical system of claim 7, wherein the surgical plan is stored and transmitted for execution by a computer-assisted surgical system(Figure 1 Haddad discloses storage of a surgical plan and transmission to a computer assisted surgery system).
Before the effective filing date of the claimed invention, it would have been obvious to one of
ordinary skill in the art to have modified the implant planning for multiple implant components using constraints of Otto to add surgical plan is stored and transmitted for execution by a computer-assisted surgical system, as taught by Haddad. One of ordinary skill would have been so motivated to be able to create and store surgical plans for execution to better enable traceability and accuracy for surgical procedures, but in this case, for a customized patient surgical plan (Para 0005, Haddad discloses: “Moreover, typical CAOS systems require a surgeon to enter considerable amount of data and other responses in order to configure, calibrate and/or drive the system during the surgical procedure.“).
Response to Arguments
35 U.S.C. 112
Applicant’s amendment in response to the rejection has been considered. The 112 rejection has been withdrawn.
35 U.S.C. 101
(Pages 8-9) Regarding the assertion that the amendments provide a specific technological improvement to computer-implemented surgical-planning systems.
Applicant's arguments filed have been fully considered but they are not persuasive. Looking at the limitations as an ordered combination adds nothing that is not already present when looking at the elements taken individually. There is no indication that the combination of elements improves the functioning of a computer or any other technology. Their collective function merely provides conventional computer implementation and do not impose a meaningful limit to integrate the abstract idea into a practical application.
(Page 10) Regarding the assertion that the claims integrate an abstract idea into a practical application.
Applicant's arguments filed have been fully considered but they are not persuasive. The additional elements highlighted above do not integrate the abstract idea into a practical application, other than the abstract idea per se, because the additional elements amount to no more than limitations which amount to mere instructions to apply an exception (MPEP 2106.05(f)) and add insignificant extra-solution activity (MPEP 2106.05(g)) to the abstract idea.
35 U.S.C. 103
Applicant’s arguments with respect to claim(s) have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
