The following patent documents might help. There are four of them with their priority dates mentioned. You should consult you patent attorneys to obtain the full text and claims of these patent/patent applications from respective offices.

KR20020014602: (18-08-2000)

Abstract- PURPOSE: An electronic commerce system for glasses through an image is provided to manage information necessary for glasses sale and information on customers in database, and to mix images of three-dimensional glasses using the information, so as to provide a service capable of selecting glasses with reality. CONSTITUTION: If a user is connected, whether the user is registered as a member is checked from member information management data(S102). If registered, a pre-registered face of the user is displayed in three-dimensional(S104). The user selects items and glasses(S106,S108). Glasses for selection interwork with a glasses DB(66). After mixing images, glasses selection points are assigned(S110). Whether to purchase the selected glasses is decided(S112). Personal information, produced character information and the glasses selection points are stored in a member information management DB(S114). Displayed specification for the selected glasses and the glasses selection points may be printed. And pressing a return key ends the steps

(JP2002014305) - 28-06-2000 PROBLEM TO BE SOLVED: To provide a system to support users so as to enable the users to easily select the spectacles meeting the users liking, a server 2 used in this system and a support apparatus. SOLUTION: The server 2 and a user terminal 3 are connected through a communication network 1. The server 2 includes a first data base 18 in which the designs of the respective parts of the spectacles are stored and a second data base in which the histories of the users are stored. If there is an access from the user terminal, the server sends the designs of the respective parts of the spectacles and the face image of the user. The selection of the desired designs is carried out at the user terminal and the face image and the spectacle image are synthesized and are displayed in a display section. If the user likes the spectacles, the user places an order. The ordering data is sent to the server and is forwarded to a manufacturer terminal. The manufacturer assembles the respective ordered parts and sends the assembly to the user. The user is able to rapidly purchase the desired spectacles.

(KR20010097951) 27-04-2000 Abstract: PURPOSE: A system and a method for buying glasses based on the Internet is provided to enable a user to directly buy glasses suitable for his/her face features, hair styles, or fashion styles. CONSTITUTION: A client(100) inputs information for buying wanted glasses. A web server(300) is connected to the client through the Internet,(200) and provides relational information corresponding to the inputted information of the client. A distribution center(400) receives order information provided through the Internet from the web server and delivers the purchased glasses to a user of the client. A face selecting part selects face type conforming with the user's face image. A hair style selecting part selects hair style conforming with the user's hair style. A fashion style selecting part selects fashion style conforming with the user's fashion style. A control part analyzes the face type, the hair style, and the fashion style selected by the face selecting part, the hair style selecting part and the fashion style selecting part and provides corresponding glasses.

Unfortunately, it is the publication date, not the priority date, that is relevant for prior art. The publication dates for the patents listed are as follows: KR20020014602 25-02-2002 based on this Espacenet link and search Korean patent database for "10-2000-0047971"; JP2002014305 has 18-01-2002; KR20010097951 has 08-11-2001; WO9729441 is OK since it has 14-08-1997.

Priority date matters, because you cannot have two patents on a single invention by different inventors just because an application filed earlier was not published. Priority date anticipates all other same inventions of future, which is why one secures a priority date. – Rahul B – 2013-06-14T01:41:32.200

You are right that priority date is relevant for issued patents, but that date is not relevant for patent applications where a patent did not get issued, at least as far as prior art is concerned. For patent applications, those are treated the same as any other "printed publication" so the published date is what is relevant in that case. I should have been more clear in my first comment to refer to these as patent applications, not issued (registered) patents (to be continued in next comment...) – user4028 – 2013-06-14T16:52:24.587

Patent application KR20020014602 was rejected so not registered (issued). JP2002014305 was "deemed to be withdrawn" so not issued. KR20010097951 was rejected so not registered (issued). WO9729441 shown here was filed but does not appear to have been issued.

– user4028 – 2013-06-14T16:53:19.840

See this link for how the rules change with the America Invents Act (AIA). Prior to AIA, the first-to-invent applied only to the U.S. via 35 USC 102(a) or 35 USC 102(e). Foreign knowledge or use did not apply except beyond the one year prior to the effective date of application/filing via 35 USC 102(b). It is for issued patents and printed publications where both foreign and U.S. are applicable if prior to invention or one year prior to application/filing, whichever is later.

– user4028 – 2013-06-14T21:52:11.807

"Invention" is generally "reduced to practice" and an application/filing is by definition reduced to practice, but an inventor can try and prove an earlier date with notes and witnesses or other evidence. After AIA, it is now "first to file" for priority. Also, there is no more U.S. distinction so any disclosure, sale, use, etc. anywhere in the world is potential prior art if prior to filing. The exception is a one-year allowance for prior disclosure by the inventor directly or indirectly. Also, any ultimately published patent OR application with a prior filing date is potential prior art. – user4028 – 2013-06-14T21:53:16.437

PURPOSE: A method for combining a customer photo image with various objects is provided to put the photo image on a 3D modelling, send the combined image over the internet, and put coloured makeup, glasses, a wig or other accessaries on the combined image in order to offer an environment similar to a real world.
CONSTITUTION: A method for combining a customer photo image with various objects comprises the steps of accessing a site server over the internet at a user personal computer(S100), performing a member subscription process at the site server(S101), sending a photo image of a user face or a body(S102), putting the sent image on a 3D modelling, storing the image in a database by various object types such as an eye, a nose, a neck, a hair and so on, storing URLs of the objects in a data processor(S104), the server calling the user to send a necessary image if a sent photo does not satisfy(S105), the user trying to put various kinds of the commodities on the photo image(S106), selecting a commodity appropriate for the user himself or herself(S107) and purchasing the commodity(S108).

Let's compare to Claim 1 of patent 7,016,824:

Interactive platform: "the user trying to put various kinds of the commodities on the photo image".

Computing device: "at a user personal computer".

3D face model: "putting the sent image on a 3D modelling, storing the image in a database by various object types such as an eye, a nose, a neck, a hair and so on"; not clear if 3D model is derived from image or by some other means (need to read full translated patent to determine), but it's clearly referring to the face.

Characteristics with respect to 3D reference frame: not mentioned explicitly.

3D representation of eyeglasses: implicit with "putting the sent image on a 3D modelling"; doesn't make sense to 3D model user image and not "commodities" including "glasses" since why would you 3D model if you were just combining images in 2D?

request over the network: "accessing a site server over the Internet" which of course is a network.

placing 3D representation onto default position: "put...glasses...on the combined image"; not clear whether there is a default or whether the user manually puts them on (need to read full translated patent to determine).

Go to the Korean patent search website:
and search for patent (application) 1020000042548
You will find that the patent I listed above was rejected, so perhaps published just means that the application was published, but the patent was not registered (accepted), but a published application is still prior art. You should be able to see the full text and diagrams of the patent though it is in Korean.

Also, for anticipation, the publication date of the prior art must be before the invention by the applicant of the patent in question OR ONE YEAR prior to the date of application of the patent in question. Since the patent in question had a related application filed on Feb 6, 2001, wouldn't we need to have prior art be prior to 2/06/2000 unless it can be proven that the applicant of the patent in question created/discovered his invention after 10/05/2000? See USPTO Anticipation rules for more details

– user4028 – 2013-06-12T19:28:17.837

Combining the prior art of EP 1123036 A4 (found earlier by Amir G) in conjunction with the above patent application could teach every element of the claim, though because it is not in a single piece of prior art, this does not count as anticipation but instead might fall under obviousness (i.e. being obvious to combine the two pieces of prior art). – user4028 – 2013-06-12T19:41:44.967

1To correct my first comment, the burden of proof is on the applicant of the patent being disputed to show that their invention was "reduced to practice" prior to the date of application of their patent (and prior to 05 Oct 2000 if this prior art is to be rejected). – user4028 – 2013-06-14T22:03:49.987


How's this?

An interactive eyewear selection system comprising a video camera (18), and digitizing system (24) for acquiring a digital image of a person's face, including the temple areas of the face; an eyeglass frame database (16) for storing digital eyeglass frame images; an automated interface for selecting an eyeglass frame image from the frames database, the image containing frame temple portions; a digital processing system (38) for automatically superimposing the selected frame image on the image of the person's face, in a composite image, such that the frame appears to be worn naturally on the person's face, and the frame temple portions are shown at the temple areas of the face; and a display device (26) for displaying the digital image of the person's face, and for displaying the composite image.

Lands End used a virtual model system from My Virtual Model as early as 1998 (see press coverage). The app let customers try on clothes on a 3D model of themselves.

I do not think you could view clothes on a 3d model of yourself that you uploaded. – George White – 2013-05-09T23:11:04.833


Levi's had a system in 1999 that created a 3-D model of your body, and then suggested jeans that would fit you.

Perhaps, based on your measurements, the system provided a virtual representation to you of how the jeans would fit?

Paper dolls were the original representation of a human + fashion item. Some of them were 3D as well.

Note that the site has copyright dates that precede the critical date of the patent in question.

The reason to combine 3D models such as those from The Sims (published Feb. 2000) with paper dolls would be obvious to anyone in the fashion industry.
