`
`Reply to your patent application of 2910612010.
`
`1st technical examination of your patent application
`
`1. Conclusion
`We are of the opinion that you will not be able to obtain a patent for your invention. When you filed
`your application, part of your invention was already known, and the new part of the invention does not
`differ significantly over the prior art, as stipulated in Section 2(1) of the Danish Patent Act. Below,
`please find an explanation of our conclusion.
`
`2. Our evaluation of your invention
`The relevant prior art is described in the following documents:

`
`D1 describes a computer-implemented method of visualizing, designing and modelling a set of teeth
`for a patient (see section [0009], [0010]):
`~ providing one or more 213 digital images;
`- providing a 3D virtual model of at least part of the patient’s oral cavity (see section [0010], [0032],
`fig 1A, 113, 4A, 4B);
`- arranging at least one of the one or more 2D digital images relative to the 3D virtual model in a 3D
`space such that the at least one 21) digital image and the 3D virtual model are aligned when viewed

`
`
`from a viewpoint, whereby the 3D virtual model and the at least one 2D digital image are both visual~
`ized in the 3D space (see section [0034], [0036] fig 2, 3A, 3B, 5);
`-the one or more 2D image comprises a patient—specific image;
`-the 2D image can be a picture showing the patient‘s lips (fig 3A, 3B);
`-the 2D image and the 3D image can be scaled to fit each other (see [0020])
`
`D2 and D3 describe a technique similar to D1. D4 and D5 describe a computer implemented method
`where a 2D image of a set of teeth is placed behind the lips of a patient on a 2D photograph, in order
`to get an aesthetic impression.
`
`The subject matter of claims I and 2 is described in Dl—D3. These claims are, therefore, not pat-
`entable.
`
`The subject matter of claims 36 differs from D1 in that a generic image, a template, a photograph
`showing lips and teeth seen from the front, and a photograph where a part of the teeth has been cut
`out, respectively, are chosen as 2D images. The problem addressed by the invention is to obtain differ—
`ent possibilities or targets in the modelling process.
`
`We consider that the person skilled in the art, computer aided modelling of teeth, would be inspired by
`his specialist knowledge to use different 2D images in order to enable a suitable guide for the model-
`ling process, and thereby suggest the solution mentioned in claims 3-6 of your application. We cannot
`see that your invention presents a surprising effect. Therefore, the subject matter of claims 36 does
`not differ significantly from the prior art. Thus you will not be able to obtain a patent for this inven-
`tion.
`
`m @U/LT;
`The subject matter of claims 7 and 8 differs from D1 in that the 3D image, i.e. the teeth, is visible be-
`hind the lips. The addressed problem is to obtain a virtual impression of the final resglt,2.e. the: patient
`with his new set of teeth. It is, however, common knowledge within the field that a ‘if) rims or a set
`of teeth can be superposed on the teeth of a photograph of a patent’s face. or that the teeth can be
`dropped into the open mouth area of a digital image (see for example D4 and D5).
`
`We consider that the skilled person would be inspired by his specialist knowledge to suggest the in-
`vention according to claims 7-8. The invention according to claims 7-8 lacks an inventive step and is
`therefore not patentable.
`
`The subject matter of claim 9 differs from D1 in that the images are scaled to fit. However, it is com-
`mon knowledge within the field that the 3D and 2D images can be scaled to fit each other (see for
`example D] to D3). We consider that a skilled person within the field would be inspired by his spe-
`cialist knowledge to suggest the invention according to claim 9. The invention according to claim 9 is
`not patentable due to lack of an inventive step.
`
`The subject matter of claim it) differs from D1 in that the modelling process is performed automati-
`cally. However, it is common knowledge to automate processes in order to reduce the overall process
`time. The invention according to claim 10 does not differ significantly from Di and is not patcntable.
`
`3. What happens next
`We welcome any comments you may have to our letter. We must receive them within the time limit
`mentioned at the top of this letter. You can send us comments ands’or new documents by post, e—mail
`or via IP Client. If you do not repiy within the time limit, your application will be temporarily shelved,
`i.e. we will discontinue examination of the application.

`
`
`If you exceed the time limit. it will still be possible for you to reply within an extended time limit of 4
`months.
`
`An extension of time limit requires that you pay a resumption fee of DKK 700 to resume the
`examination of your application The fee must be paid when you send us your reply.
`
`If you exceed the extended time limit, your application will be finally shelved.
