`
`1-12 of U.S. Patent No. 10,417,275 (the “’275 Patent”) filed by Meta Platforms, Inc.,

`Case IPR2023-00059
`U.S. Patent No. 10,417,275
`The Board should deny institution because Meta fails to establish that its
`
`arguments are reasonably likely to succeed in establishing that Claims 1-26 of the
`
`’275 patent (“the Challenged Claims”) are unpatentable.5
`
`In particular, the Board should exercise its discretion to deny institution of
`
`inter partes review of the ’275 Patent, because both grounds asserted in the Petition
`
`rely primarily on Sharpe, which does not qualify as prior art for the ’275 Patent.
`
`Specifically, Sharpe is not prior art with respect to Claims 1-12 because the inventor
`
`conceived of those claims before the filing date of Sharpe, September 26, 2000, and
`
`diligently reduced the invention to practice. Submitted herewith is a Declaration
`
`pursuant to 37 CFR § 1.131 that satisfies all legal requirements to demonstrate that
`
`Sharpe, as cited by the Petitioner, is in fact not a prior art reference to the ’275 patent.
`
`Specifically, the application leading to the ’275 patent was filed on November 15,
`
`2000, approximately six weeks after the critical date for Sharpe. Per the prosecution
`
`history, the inventors signed Declarations and had completed the provisional patent
`
`application as early as August 15, 2000. Thus, the provisional application was being
`
`finalized approximately one month before Sharpe’s filing date. Further, as described
`
`below, there is evidence of actual reduction to practice as early as April 2000,
`
`approximately five months before Sharpe’s critical date.
`
`
`5 37 C.F.R. § 42.208(c).
`

`

`

`Case IPR2023-00059
`U.S. Patent No. 10,417,275
`A denial is also justified because the Petition fails on the merits. The Petition
`
`both fails to establish proper claim constructions and proper motivations to combine
`
`the references in grounds 1-2 as statutorily required. As such, the Petition fails to
`
`establish that its arguments are reasonably likely to succeed in establishing that the
`
`Challenged Claims are unpatentable.
`
`The Board is urged to consider the points raised herein and to not institute an
`
`Inter Parties Proceeding (IPR) that will only waste time and resources. The Petitioner
`
`seeks to destroy precious remaining patent term of a valid patent and to deny the
`
`Patent Owner his constitutional and statutory rights to pursue legitimate claims
`
`against infringers.
`
`None of the grounds raised by the Petitioner have demonstrated a reasonable
`
`likelihood that at least one of the challenged claims is unpatentable. See 37 C.F.R.
`
`§ 42.108(c). Hence, the Board should deny the Petition in its entirety.
`
`II.
`
`BACKGROUND
`The ’275 Patent
`The ’275 patent is directed to a system, computer program, and method for
`
`A.
`
`storing and sharing images such as photographs via a communications network and
`
`for permitting the identification of objects within the images. The invention allows
`
`the identification of objects, such as persons within the photos, without requiring the
`
`
`
`3
`
`

`

`Case IPR2023-00059
`U.S. Patent No. 10,417,275
`person submitting the photos to type in identification information for each and every
`
`photo in a photo album. Ex-1001, Abstract.
`
`1.
`
`Existing Technology
`In the late 1990’s and early 2000’s at the time of the invention, people began
`
`creating web pages for online photo albums, which offered advantages over
`
`traditional photo albums. Ex-1001, 1:35-40. Several websites existed which allowed
`
`users without programming skills to create and maintain online photo albums by
`
`simply uploading photos they wished to add to the album. Ex-1001, 1:45-60.
`
`These websites offered many advantages to users, but also suffered from
`
`many limitations. For example, the websites did not allow users to identify objects
`
`and individuals within the photos without cumbersome limitations such as requiring
`
`individuals to wear a badge in the photos for identification. Further, the websites did
`
`not provide search capabilities for identifying photos of specific individuals once
`
`identified, or ways to distinguish between different types of the same object (i.e.,
`
`identifying one clown from another clown). Finally, the websites did not offer a way
`
`to quickly and easily send notification to individuals that they had been identified in
`
`a photo. Ex-1001, 1:62-3:44.
`
`2.
`
`Advantages Provided by the ’275 Patent
`The ’275 patent addressed these deficiencies with a system that allows users
`
`to supply and/or receive information about the existence of objects within images.
`
`
`
`4
`
`

`

`Case IPR2023-00059
`U.S. Patent No. 10,417,275
`Figure 2 of the ’275 patent, reproduced below, demonstrates some of the novel
`
`aspects in a particular embodiment. As shown below, a user database receives,
`
`stores, and provides information about people and/or objects identified within the
`
`photo.
`
`
`
`Ex-1001, Fig. 2.
`
`For example, the User’s database can be populated to include a user identifier
`
`with information such as the user’s name, email-address, home page address, and/or
`
`a list of contacts. The Images database receives and stores information about photos
`
`and can be populated to include, for each photo, a photo identifier unique to the
`
`photo and the location of the image file on the network. The Images database may
`
`also include descriptive information about the photo such as a caption or the date the
`
`photo was taken. The Identifications database may receive, store, and provide
`
`
`
`5
`
`

`

`Case IPR2023-00059
`U.S. Patent No. 10,417,275
`information about relationships between users and photos. For example, the
`
`Identifications database may contain fields specifying what kind of relationship
`
`exists between a photo and a user, information about the location within a photo, or
`
`the coordinates that a user or other person appears. Ex-1001, 6:59-7:37.
`
`The ’275 invention thus permits the identification of objects within images
`
`without requiring the person submitting the photos to input the information for each
`
`and every photo in an album. The ’275 invention also allows users to share their
`
`photos with those individuals identified in them, and to automatically search for
`
`photos and/or certain people in photos. Ex-1001, Abstract.
`
`3.
`
`The ’275 Patent Components
`The host computer of the ’275 system may be any computing device such as
`
`a network computer running Windows 2000, Novel Netware, Unix, or any other
`
`network operating system. The host computer may be connected to a firewall
`
`computer at the boundaries of network to prevent tampering with information stored
`
`on or accessible by the host computer. If the invention is implemented with the
`
`Internet, the host computer may include conventional web hosting operating
`
`software, an Internet connection such as a modem, DSL converter or ISDN
`
`converter, and be assigned an IP address and corresponding domain name so that the
`
`website hosted thereon can be accessed via the communications network. Ex-1001,
`
`5:26-39.
`
`
`
`6
`
`

`

`Case IPR2023-00059
`U.S. Patent No. 10,417,275
`The client computer of the ’275 system provides a system interface for a user.
`
`The client computer allows a user to access a host computer via a communications
`
`network in order to upload and/or view photographs. Each client computer may also
`
`include or can access a conventional Internet connection such as a modem, Digital
`
`Subscriber Line (DSL) converter, or Integrated Service Digital Network (ISDN)
`
`converter and a web browser that permits it to access and view data over the Internet.
`
`Ex-1001, 5:40-56.
`
`The communications network may be internet or any other communications
`
`network such as local area network, a wide area network, a wireless network, an
`
`intranet or a virtual private network. Ex-1001, 5:56-64.
`
`The computer program or programs embodying one or more aspects of the
`
`invention are stored in or on computer-readable medium residing on or accessible
`
`by host computer and provide a mechanism for instructing host computer to operate
`
`the invention as described herein. The computer programs typically comprise
`
`ordered listings of executable instructions for implementing logical functions in host
`
`computer and user computers coupled with host computer. Ex-1001, 5:65-6:2.
`
`The host computer comprises server engine which is programmed to operate
`
`or host a website and serve as a repository for images and identification information
`
`for objects within the images as described in more detail below. The images may be
`
`photographs, graphics, artwork, or any other digital image that contains or depicts
`
`
`
`7
`
`

`

`Case IPR2023-00059
`U.S. Patent No. 10,417,275
`one or more objects. The objects within the images may include people, animals,
`
`plants, buildings, places, or anything else shown in images. In one embodiment of
`
`the invention, the images and objects are referred to (but not limited to) as
`
`photographs and people, respectively. Ex-1001, 6:32-44.
`
`In order to implement the ’275 invention, the host system will access a server
`
`system or database system configured to support the functionality. As discussed
`
`above, ’275 the system may utilize a Users database, Identifications database, and
`
`Images database.
`
`When the host computer wishes to find all the people identified in a specific
`
`image, it will look for all records in the Identifications database 240 where the Image
`
`I.D. equals a supplied I.D. When the host computer wishes to find all the photos that
`
`a specific user appears in, it will search for all records in the Identifications database
`
`where the user's I.D. equals a supplied I.D. Ex-1001, 6:59-65.
`
`The host computer may access information in the Identifications database to
`
`find all the people identified in a given photo or to find all the photos a given person
`
`has been identified in. Ex-1001, 8:44-9:5.
`
`Figure 1 of the ’275 patent, reproduced below, represents an exemplary
`
`schematic diagram of the ’275 patent components as detailed above.

`
`The Operation of the ’275 Patent Inventions
`In operation, users of the ’275 system can supply and/or receive information
`
`about the existence of objects within images. The process initiates by obtaining
`
`image data comprising one or more objects. For instance, a user may provide a
`
`system embodying the invention a digital photo of a group of friends and family
`
`members. Ex-1001, 9:35-41.
`
`The ’275 system obtains identifying information from the user where the
`
`identifying information relates to the existence of at least one object in the image
`
`(e.g., digital photo). For example, when viewing an image, a user may select the
`
`
`
`9
`
`

`

`Case IPR2023-00059
`U.S. Patent No. 10,417,275
`name of a person from a list to identify this person as existing in the image. The
`
`identifying information may be stored in the databases. Ex-1001, 9:41-49.
`
`The identifying information is also displayed to a user. The identifying
`
`information may be displayed in several different ways. For example, the system
`
`may provide an output displaying an image and listing the names of all objects
`
`identified therein. In another example, the system may provide a listing of all images
`
`a specific person is identified in. Ex-1001, 9:50-58.
`
`B.
`
`ALLEGED PRIOR ART
`As shown above, Meta presents two grounds challenging claims 1-26 using
`
`various combinations of Sharpe, Eintracht and FotoFile.6 These references are
`
`described briefly below.
`
`1.
`
`Sharpe
`Sharpe discloses a system and method for archiving and retrieving digital
`
`media items based on episodic memory of predefined associated groups of one or
`
`more people. Ex-1005, Abstract; 1:5-10. However, as described in detail below,
`
`Sharpe is not prior art to the ’275 Patent.
`
`The Sharpe disclosure describes the invention as archiving and retrieval of
`
`photos or digital media items based on three fundamental indices, which include: (1)
`
`
`6 Petition, 5-6.
`
`
`
`10
`
`

`

`Case IPR2023-00059
`U.S. Patent No. 10,417,275
`group event types, (2) persons associated with the digital media item and (3) a time
`
`period. Ex-1005, 1:46-2:02. The Sharpe disclosure further describes these
`
`fundamental indices as based on the way people remember things. Ex-1005, 1:65-
`
`2:02. Further, this method of limiting indices to a group with a shared experience
`
`limits the number of people and event types needed for indexing or retrieving. Ex-
`
`1005, 2:01-11.
`
`The Sharpe system provides a method of archival and retrieval tied to the way
`
`people remember things, based on three fundamental indices which track with
`
`episodic memory, of which is selected by the user or group. For example, based on
`
`a specific time and date, or a time range. Ex-1005 2:5-10.
`
`Because the collection and indexing of the digital media
`items is based on the episodic memory of the group, i.e.
`they have chosen the material and indexed it according
`to its relevance to them, the retrieval and browsing
`through data digital items are attuned to the memories of
`the user. The aim of retrieval is not to retrieve a specific
`digital media item but instead to retrieve any digital
`media items relating to a memorable episode. Thus the
`indexing system does not uniquely identify digital media
`items, but replaces them within a highly personal
`framework.
`
`
`
`11
`
`

`

`Case IPR2023-00059
`U.S. Patent No. 10,417,275
`
`Ex-1005, 2:12-21 (emphasis added). 7
`
`Figure 1 shows a block diagram overview of the Sharpe system. Sharpe first
`
`discloses users of a group who are registered by a group registration process in a
`
`database. The members then work together to identify, collect, translate or create
`
`digital media items in different media which represent the culture of the group. Ex-
`
`1005, 5:4-17.
`

`
`The storage process associates, with each item to be stored, an identifier and
`
`other associated information for the index. The storage process includes identifying
`
`a group of people from the database, identifying one or more multimedia items to be
`
`archived with index information, selection of an event type from a table of possible
`
`event types for the group of people and selecting a date from the calendar.
`
`Individuals within the group identified on the database are selected using the
`
`database for association with the selected item(s). The storage process indexes one
`
`or more multimedia items in accordance with the group, members of the group,
`
`one or more event types, and a date. Ex-1005, 5:24-40.
`
`The storage process results in stored or archived multimedia items, wherein
`
`the multimedia database can be structured so that the multimedia items are stored
`
`separately to the index data. Ex-1005, 5:41-45. The retrieval process then allows the
`
`digital media items to be retrieved and displayed. Ex-1005, 5:46-49.

`
`Eintracht
`At a high level, Eintracht discloses a system for collaborative document
`
`annotation whereby notes/annotations associated with an image are stored in a notes
`
`database on a central notes server. The collaborative document annotation is based
`
`on the exchange of notes attached to web based documents (or images), and the
`
`
`
`13
`
`

`

`Case IPR2023-00059
`U.S. Patent No. 10,417,275
`system is suitable for use over a network such as the Internet based World Wide
`
`Web. Ex-1006, Abstract, 1:6-12.
`
`Eintracht describes problems related to viewing and annotating documents on
`
`World-Wide-Web browsers, including the lack of ability to annotate documents
`
`when information needs to be exchanged among multiple people in multiple
`
`locations. To address these issues, Eintracht introduces a system that “allow[s]
`
`multiparty collaboration based on the asynchronous exchange of annotations over a
`
`network such as the Internet without the requirement that all parties wishing to
`
`collaborate be simultaneously logged on to a server.” Ex-1006, 2:1-5.
`
`Eintracht discloses a system for differentiating between notes generated by
`
`various users. Each user chooses a unique user ID that forms a Note Owner identifier
`
`(Note Owner ID). Ex-1006, 8:6-17. Eintracht also discloses a Note Document ID
`
`which identifies documents and document aggregations themselves. Ex-1006, 8:18-
`
`23.

`
`FotoFile
`FotoFile is a published paper that discloses a system for multimedia
`
`organization and retrieval, based upon the design and goal of making multimedia
`
`content accessible to consumers. Ex-1011, 1, Abstract. FotoFile discloses artificial
`
`intelligence algorithms to locate the named user in other images by blending human
`
`
`
`14
`
`

`

`Case IPR2023-00059
`U.S. Patent No. 10,417,275
`annotation with automated algorithms to support search, browsing, and retrieval
`
`technologies for multimedia. Id.
`
`FotoFile discloses a face detection and recognition system in which, when
`
`given faces of new people, the face recognition system attempts to match the identity
`
`of the face. Id. at 4. FotoFile groups photographs and orders the events
`
`chronologically to mirror human episodic memory. Id.

`
`Carey
`Carey discloses a method, system and computer program product for instant
`
`message communications. Ex-1007, Abstract. Carey allows team members in
`
`different locations to converse. Ex-1007, 1:24-26.
`
`Carey discloses a method for remotely creating instant message name lists for
`
`cellular devices. A user subscribes by registering, and then can create an instant
`
`message name list by entering the instant message name corresponding to a desired
`
`recipient. The name is then saved in a look-up table in a database, and stored in
`
`relation to predefined user profile information. Ex-1007,4:6-25.
`
`III. LEVEL OF ORDINARY SKILL
`For the purposes of this preliminary response, Patent Owner submits that a
`
`POSITA in the timeframe of the invention would have a bachelor’s degree in
`
`computer science, electrical engineering, or computer engineering, and at least two
`
`years of experience designing Web-based media applications.

`
`IV. CLAIM CONSTRUCTION
`In inter partes reviews filed after November 13, 2018, the Board construes
`
`claim terms based on their ordinary and customary meaning in accordance with
`
`Phillips v. AWH Corp., 415 F.3d 1303, Fed. Cir. 2005) (en banc). 83 Fed. Reg. 51340
`
`(October 11, 2018). Under Phillips, claims must be construed so as to sustain their
`
`validity, if possible. The specification is the “best source for understanding a
`
`technical term,” to be supplemented, “as needed, by the prosecution history.” Id. at
`
`1315.
`
`Patent Owner submits that no term requires express construction. Patent
`
`Owner explicitly reserves the right to construe claim limitations should the Board
`
`institute review.
`
`V.
`
`Argument
`As Petitioner, Meta has the burden of proof to establish that it is entitled to its
`
`requested relief.8 Here, Meta must demonstrate a reasonable likelihood that the
`
`Challenged Claims are unpatentable and would have been obvious in view of the
`
`combinations cited in the Petition’s alleged grounds for unpatentability. The Board
`
`should deny institution, because Meta has failed to meet this burden.
`
`
`8 37 C.F.R. § 42.108(c).

`U.S. Patent No. 10,417,275
`
`A.
`
`Sharpe Does Not Qualify as Prior Art
`Both grounds challenging the independent claims rely on Sharpe, which was
`
`filed on September 26, 2000, only one month prior to the filing of the provisional
`
`application to which the ’275 patent claims priority. However, the inventor of the
`
`’275 patent conceived of the invention claimed in the ’275 patent before Sharpe was
`
`filed, and worked diligently to reduce it to practice, both as an actual product and
`
`then also by filing the provisional application on November 15, 2000. Evidence
`
`shows that the ’275 patent antedates the Sharpe reference. Disqualifying this
`
`reference, which forms the basis for each of the two grounds asserted in the Petition,
`
`should result in denial of all the obviousness grounds asserted in the Petition.
`
`“In an inter partes review, the burden of persuasion is on the petitioner to
`
`prove ‘unpatentability by a preponderance of the evidence,’ 35 U.S.C. § 316(e), and
`
`that burden never shifts to the patentee.” Dynamic Drinkware, LLC v. Nat’l
`
`Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015). Thus, while the burden of
`
`production may shift to a patentee (e.g., when arguing that a reference does not
`
`qualify as prior art), the burden of persuasion remains with the petitioner. Id. at 1379.
`
`Thus, while a patentee bears the burden of coming forward with evidence of earlier
`
`conception, diligence, and/or reduction to practice, the burden of proving that a
`
`reference qualifies as prior art remains with the petitioner. See Freebit AS v. Bose
`
`Corp., No. IPR2017-01308, 2017 WL 5202106 at *6 (PTAB Nov. 8, 2017).

`

`Case IPR2023-00059
`U.S. Patent No. 10,417,275
`There is a remedy in patent law that allows an inventor to “swear behind” a
`
`reference if the inventor had possession of the subject matter disclosed by the
`
`reference in question. In re Stempel, 241 F.2d 755, 759 (C.C.P.A. 1957) (“We are
`
`convinced that under the law all the applicant can be required to show is priority
`
`with respect to so much of the claimed invention as the reference happens to show.
`
`When he has done that he has disposed of the reference.”). “Rule 131 provides a
`
`procedure by which the applicant is permitted to show, if he can, that his date of
`
`invention was earlier than the date of the reference.” Id. at 760.
`
`A patent owner may antedate a reference by either showing actual reduction
`
`to practice prior to the effective date of the adverse reference, or conception prior to
`
`the effective date of the adverse reference plus diligence to actual or constructive
`
`reduction to practice by the patent owner. In re Steed, 802 F.3d 1311, 1316 (Fed.
`
`Cir. 2015); see MPEP 2138.01(II) (example 3). “The princ
