`
`I.
`
`INTRODUCTION
`1. My name is Benjamin B. Bederson, and I have been retained by counsel
`
`for Netflix Inc. (“Netflix” or “Petitioner”) to submit this Declaration in support of
`
`Netflix’s petition for Inter Partes Review (“IPR”) and cancellation of claims 1–
`
`233(the “Challenged Claims”) of U.S. Patent No. 8,478,245 (“the ’245 patent”) (Ex.
`
`1001), which I understand has been assigned to GoTV Streaming, LLC (“GoTV” or
`
`“Patent Owner”).
`
`2.
`
`I have been asked to opine on whether the ’245patent is anticipated
`
`and/or rendered obvious by the prior art. My opinions are based on my years of
`
`education, research and experience, as well as my investigation and study of relevant
`
`materials. The materials that I considered for this Declaration include all exhibits
`
`cited in this Declaration.
`
`3.
`
`I may rely upon these materials, my knowledge and experience, and/or
`
`additional materials to rebut arguments raised by Patent Owner. Further, I may also
`
`consider additional documents and information in forming any necessary opinions,
`
`including documents that may not yet have been provided to me.
`
`4. My analysis of the materials produced in this investigation is ongoing
`
`and I will continue to review any new material as it is provided. This Declaration
`
`represents only those opinions I have formed to date. I reserve the right to revise,
`
`
`
`
`
`Netflix. Ex. 1002

`

`

`Declaration of Benjamin B. Bederson
`
`IPR2023-00758
`
`supplement, and/or amend my opinions stated herein based on new information and
`
`on my continuing analysis of the materials already provided.
`
`5.
`
`I am being compensated at my standard consulting rate of $600/hour
`
`for my time spent working on issues in this matter. I am also being reimbursed for
`
`any reasonable and customary expenses associated with my work and testimony. I
`
`have no financial interest in, or affiliation with, Petitioner or Patent Owner. My
`
`compensation is not dependent upon the outcome of, or my testimony in, the present
`
`IPR or any litigation proceedings.
`
`II. QUALIFICATIONS
`6.
`I am currently Professor Emeritus of Computer Science at the
`
`University of Maryland (“UMD”). From 2014 to 2018, I was the Associate Provost
`
`of Learning Initiatives and Executive Director of the Teaching and Learning
`
`Transformation Center at the UMD. I am a member and previous director of the
`
`Human-Computer Interaction Lab (“HCIL”), the oldest and one of the best known
`
`Human-Computer Interaction (“HCI”) research groups in the country.
`
`7.
`
`Last year, I co-founded the J.S. Bryant School, a therapeutic high
`
`school to launch in 2025. I was also co-founder and Chief Scientist of Zumobi, Inc.
`
`from 2006 to 2014, a Seattle-based startup that is a publisher of content applications
`
`and advertising platforms for smartphones. I am also co-founder and co-director of
`
`the International Children’s Digital Library (“ICDL”), a web site launched in 2002
`
`
`
`2
`
`Netflix. Ex. 1002
`
`

`

`Declaration of Benjamin B. Bederson
`
`IPR2023-00758
`
`that provides the world’s largest collection of freely available online children’s
`
`books from around the world with an interface aimed to make it easy for children
`
`and adults to search and read children’s books online. I am also co-founder and prior
`
`Chief Technology Officer of Hazel Analytics, a data analytics company to improve
`
`food safety and better public health whose product sends alerts in warranted
`
`circumstances.
`
`8.
`
`In addition, I have for more than 25 years consulted for numerous
`
`companies in the area of user interfaces, including EPAM, Hillcrest Labs, Lockheed
`
`Martin, Logitech, Microsoft, NASA Goddard Space Flight Center, the Palo Alto
`
`Research Center, and Sony.
`
`9.
`
`The devices and methods claimed in the ’245 Patent generally relate to
`
`human-computer interaction, graphics and rendering on wireless devices. For more
`
`than 30 years, I have studied, designed, and worked in the field of computer science
`
`and HCI. My experience includes 30 years of teaching and research, with research
`
`interests in HCI and the software and technology underlying today’s interactive
`
`computing systems with a focus on wireless devices, graphics and rendering.
`
`10. At UMD, I have been focused primarily on the area of HCI, a field that
`
`relates to the development and understanding of computing systems to serve users’
`
`needs. Researchers and practitioners in this field are focused on making universally
`
`usable, useful, efficient, and appealing systems to support people in their wide range
`
`
`
`3
`
`Netflix. Ex. 1002
`
`

`

`Declaration of Benjamin B. Bederson
`
`IPR2023-00758
`
`of activities. My approach is to balance the development of innovative technology
`
`that serves people’s practical needs.
`
`11. Example systems following this approach that I have built include
`
`Cortex-I (1992 embedded computer vision system that sensed licensed plates with
`
`custom motor, camera and controller), Audio Augmented Reality (1995 embedded
`
`system for sensing a user’s location and playing audio suited to that location),
`
`Fisheye Menus (2000 software for sensing movement within and selection of linear
`
`list of items in a menu), PhotoMesa (2001 software for end users to browse personal
`
`photos), DateLens (2002 software for end users to use their mobile devices to
`
`efficiently access their calendar information), SlideBar (2005 linear sensor to control
`
`scrolling), LaunchTile (2005 “home screen” software for mobile devices to allow
`
`users to navigate apps in a zoomable environment), SpaceTree (2002 software for
`
`end users to efficiently browse very large hierarchies), ICDL (2001 International
`
`Children’s Digital Library), and StoryKit (a 2009 iPhone app for children to create
`
`stories).
`
`12. LaunchTile led to my co-founding of Zumobi Inc. in 2006, where I was
`
`responsible for investigating new software platforms and developing new user
`
`interface designs that provided efficient and engaging interfaces to permit end users
`
`to access a wide range of content on mobile platforms (including the iPhone and
`
`Android-based devices). For example, I designed and implemented software called
`
`
`

`
`“Ziibii,” a “river” of news for iPhone that used a capacitive sensor for controlling
`
`linear movement through news, software called “ZoomCanvas,” a zoomable user
`
`interface for several iPhone apps, and iPhone apps including “Inside Xbox” for
`
`Microsoft and Snow Report for REI.
`
`13. Starting in the mid-1990s and going through the 2000s, I worked on a
`
`range of “zoomable user interfaces” (ZUIs) that supported users in navigating large
`
`information spaces by zooming in and out of the information on the screen. I built
`
`several different ZUI systems over the years, including Pad++, Jazz, and Piccolo. I
`
`wrote Pad++ in C++ using the X Windows System including a number of techniques
`
`to support high performance interactive visualization.1
`
`14. Pad++ included a custom web browser which I built from scratch in
`
`1994 and distributed as open source software at the Pad++ web site. That web
`
`browser was described in numerous publications including “Pad++: A Zoomable
`
`Graphical Interface for Exploring Alternate Interface Physics”2.

`
` It supported the version of HTML available at the time (HTML 1.0) as
`
`well as an embedded scripting language. The following images are from a custom
`
`web browser that I built that used a “zoomable user interface” to show a visual
`
`representation of which pages a user visited.3
`
`
`
`16. By 1998, my team had combined our web browser with Netscape
`
`
`
`Navigator (a standard web browser of the time) to offer a graphical web history,
`
`visually showing what pages a user had visited with an application we called

`
`“PadPrints”.4 We did this by implementing a web “proxy,” which was a standard
`
`way at the time to modify the built-in behavior of web browsers. Some proxies work
`
`by intercepting all web traffic coming from and going to a web browser. Once
`
`intercepted, the proxy can do whatever it wants with the traffic, caching it for better
`
`performance, simply passing the traffic through and monitoring it, it can modify the
`
`data itself, or hold that connection and open new connections. PadPrints’ proxy
`
`worked by monitoring the traffic and letting PadPrints know what the user was doing
`
`so PadPrints could display the web history.

`17. Starting in 2001 and continuing for several years, I worked on photo
`
`management systems. I wrote a paper5 in 2001 describing PhotoMesa, a zoomable
`
`image browser using a novel 2D layout algorithm I called “quantum treemaps” to
`
`position the images on the screen in a way that attempted to fill the screen while
`
`keeping groups of related images together. As indicated in the figure below,
`
`PhotoMesa could display many hundreds of images at a time by showing small
`
`thumbnails, by showing larger thumbnails when the mouse hovered over a small
`
`thumbnail, and by allowing a user to zoom in to see a high resolution version of the
`
`images.

`18. At the ICDL, I have since 2002 been the technical director responsible
`
`
`
`for the design and implementation of the web site, www.childrenslibrary.org
`
`(originally at www.icdlbooks.org). In particular, I have been closely involved in
`
`designing the user interface as well as the software architecture for the web site since
`
`its inception in 2002. The ICDL includes a display of search results that include
`
`thumbnails of book covers where 8 of the book covers are shown at a time. Pressing
`
`the right arrow uses AJAX web technology to dynamically retrieve and display the
`
`next 8 book covers from the server without having to reload the entire page. We
`
`switched from a similar version of this interface to this AJAX-based approach in
`
`about 2006.

`
`I was heavily involved in the research and development of mobile
`
`19.
`
`device applications during the early 2000’s. For example, I envisioned, designed and
`
`built DateLens in 2002-2004 to create a richer and more usable calendar for the
`
`Microsoft PocketPC platform as well as desktops. One of its innovations was its
`
`design that enabled it to scale between small (mobile) and large (desktop) computers.
`
`It also had a special double-headed scroll bar that allowed a user to touch scroll and
`
`also control how much information was presented on the screen at a time. I started

`
`DateLens as a research project and eventually sold it commercially. DateLens
`
`displayed calendar data that came straight from the Microsoft PocketOutlook
`
`database and allowed modification and viewing of appointments. The research
`
`website from that time period that describes DateLens is still available at
`
`http://www.cs.umd.edu/hcil/datelens/ which shows screenshots and a picture of me
`
`demonstrating DateLens to Bill Gates. The commercial website from that time
`
`period is also available at http://www.windsorinterfaces.com/datelens.shtml, which

`shows a number of news articles reviewing DateLens at
