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 .
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 1-2, 4, 6-13, 16-18, 20-22, and 24-25 are rejected under 35 U.S.C. 101 because the claimed invention is directed to a judicial exception (i.e., a law of nature, a natural phenomenon, or an abstract idea) without significantly more.
Step 1:
In regards to claims 1-4, 6-13, 6-18, 20-22, and 24-25, the claims directed towards “A method” that claims that recites “receiving, by a computing device, intraoral scan data”; “determining, by the computing device, one or more treatment plans”; “modifying, by the computing device, the virtual maxillary arch and virtual mandibular arch”; “virtually articulating, by the computing device”; “computing, by the computing device, for each intermediate state and the final state and for each mandibular pose”; “automatically modifying, by the computing device”; “outputting, by the computing device”; and “generating, by the computing device”. The claims “method” is within the 35 U.S.C. 101 statutory category of a process (MPEP 2106.0.3), but falls into the judicial exception (MPEP 2106.04).
Step 2A:
In regards to claims 1-4, 6-13, 6-18, 20-22, and 24-25, the claims are found to be directed to an abstract idea without significantly more. The claim(s) recite(s) “receiving, by a computing device, intraoral scan data”; “determining, by the computing device, one or more treatment plans”; “modifying, by the computing device, the virtual maxillary arch and virtual mandibular arch”; “virtually articulating, by the computing device”; “computing, by the computing device, for each intermediate state and the final state and for each mandibular pose”; “automatically modifying, by the computing device”; “outputting, by the computing device”; and “generating, by the computing device”.
The claims recite abstract ideas that include data manipulation to determine the treatment plans which would result in minimal occlusion interactions that would provide discomfort. The abstract ideas are as such drawn to a mental process.
In practice, an orthodontist looking at scans of the patient’s maxillary arch and mandibular arch to determine the correct appliance over a period of time to develop a treatment plan. Furthermore, an orthodontist can make multiple treatment plans based on contact points of the maxillary arch and mandibular arch. In addition, an orthodontist can determine a dynamic collision quality metric based on such contact points and present the data for each treatment plans developed. Further, an orthodontist can determine a dynamic occlusion quality metric which relates to how much the teeth are in contact with one another and how many collisions would be present. This can be done by simulating the occlusal interactions in their mind. An orthodontist can draw out polygonal mesh represent the surfaces of teeth and determine potential collisions between unique pairs of teeth. In addition, an orthodontic can produce treatment plans and a treatment report to reduce the undesirable occlusal contacts and discomfort based on reducing the dynamic occlusion quality metric. An orthodontist can as such develop an image as to how the appliance should be to reposition the teeth based on the treatment plan. Thus, the orthodontist can develop a treatment plan which can be sent to fabricate aligners. As the implementation can be done mentally, the limitations are found to be abstract.
This judicial exception is not integrated into a practical application because it is found the method implements computer elements wherein the recited computer elements do not add a meaningful limitation to the abstract idea as it would simply be implementing such abstract idea on a computer.
Step 2B:
In regards to claims 1-4, 6-13, 6-18, 20-22, and 24-25, the computing device is the additional element that are significantly more than the mental process. However, it is not significantly more than the judicial exception as it does not provide meaningful limitation as it provides no improvement to the technology.
The claimed invention is found to disclose the intended use of a general-purpose computer or data processing device (such as evidenced in claims 1, 16, and 24), however, there is no disclosure in the written description that the processing unit or computer is anything more than a generic component, nor is there any disclosure that the method improves in which the processing unit operates. It is found that a computer or processing unit that is used in a conventional manner to perform convention computer functions that are well understood and routine does not amount to “significantly more” than the judicial exception. The claim itself does not go beyond numerical values based on mathematical algorithms with a general-purpose computer. With regards to claim 16 it is found that the memory and processor are the additional element that are significantly more than the mental process. However, it is not significantly more than the judicial exception as it does not provide meaningful limitation as it provides no improvement to the technology.
In regards to claims 1-2, 4, 6-13, 16-18, 20-22, and 24-25, the claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because the claimed method is directed to a mental process, concepts that are capable of being performed in the human mind, including observations, evaluations and judgements.
In practice, an orthodontist looking at scans of the patient’s maxillary arch and mandibular arch to determine the correct appliance over a period of time to develop a treatment plan. Furthermore, an orthodontist can make multiple treatment plans based on contact points of the maxillary arch and mandibular arch. In addition, an orthodontist can determine a dynamic collision quality metric based on such contact points and present the data for each treatment plans developed. Further, an orthodontist can determine a dynamic occlusion quality metric which relates to how much the teeth are in contact with one another and how many collisions would be present. This can be done by simulating the occlusal interactions in their mind. An orthodontist can draw out polygonal mesh represent the surfaces of teeth and determine potential collisions between unique pairs of teeth. In addition, an orthodontic can produce treatment plans and a treatment report to reduce the undesirable occlusal contacts and discomfort based on reducing the dynamic occlusion quality metric. An orthodontist can as such develop an image as to how the appliance should be to reposition the teeth based on the treatment plan. Thus, the orthodontist can develop a treatment plan which can be sent to fabricate aligners. As the implementation can be done mentally, the limitations are found to be abstract.

Response to Arguments
Argument #1: Applicant argues that the inclusion of the step involving the simulation of mandibular articulation and the computation of three-dimensional interaction metrics go beyond anything that could be mentally performed. This is because it requires complex spatial data processing and simulating multi-body dynamics which applicant states requires a computer. Further, applicant argues that the claims do not direct to a generic data processing but describes a structural sequence of technical steps that are far beyond performing mental evaluations. Applicant also points out that the claims signify more than alleged abstract ideas as they are neither conventional nor routine.
Response #1: Applicant’s argument is found to not be persuasive as though many inventive novelties are present, it does not overcome Step 2A or 2B of the 101 rejection. It is suggested to include a manufacturing step of making the dental device to potentially overcome the 101 rejection.
Though the operation would be complex, an orthodontist can still be capable of being completed. It is known that orthodontist have long carried out their trade before the usage of computers and computer software and as such would obviously determine occlusal contact points found with the patient’s arches and determine the severity of the contact points. Further, an orthodontist would in turn be able to determine the proper amount of contact points to be present that would reduce discomfort to the patient and reduce malocclusion through the making of a treatment plan. The inclusion of the new claim limitations to the independent claims can still be achievable by an orthodontist despite the complexity of the process. For example, an orthodontist can draw and map out polygonal meshes of teeth surfaces and see potential unique collisions that can be present between teeth.
It should be noted that claim 23 does not invoke a 101 rejection as it presents the physical step of fabricating the particular appliance/aligner. By amending the independent claims to include the fabrication step, it would overcome the current 101 rejection.
Argument #2: Applicant argues that Fisker nor Matov does not provide disclosure of the new amended claim language to the independent claims.
Response #2: Applicant’s argument is found to not be persuasive as Matov does disclose teaching of representing teeth surfaces with polygonal meshes and using the collisions represented by the meshes to determine collision count (Par. 46, 60 and 96). Wen is then used for the teaching that the collisions being reviewed are unique pairs of colliding teeth.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant’s disclosure. See Form PTO-892.
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
