`
`Education and Experience
`

`
`
`

`
`
`
`4.
`
`I am a Web-development, ecommerce, and SEO (“Search Engine
`
`Optimization”) consultant and author, and I am the owner of Peter Kent Consulting
`
`LLC. I provide ecommerce consulting to companies seeking to improve their online
`
`business, including in the areas of search-engine optimization, online advertising,
`
`Web development, and ecommerce-site “conversions,” and usability. My business
`
`address is 399 East Bayaud Avenue, Denver Colorado 80209.
`
`5.
`
`I have worked extensively with computer technologies since early
`
`1979, and have been involved in a wide range of capacities within the technology
`
`business, beginning with operating computer equipment used for oil-field drilling-
`
`engineering and drilling-optimization purposes; then, starting in 1981, working with
`
`software-development teams (initially with the title of Systems Analyst), testing
`
`hardware and software systems, documenting systems, designing user interfaces,
`
`training users, as well as installing, maintaining, and repairing systems. Since the
`
`mid-1980s, I have been involved in various additional functions in the technology
`
`business, including writing computer books, writing video-training scripts, creating
`
`websites, designing software, project managing software development, developing
`
`online-marketing strategies, managing online-advertising and search-engine-
`
`optimization campaigns, and more.
`
`6.
`
`I began working online (using mechanisms such as CompuServe™ and
`
`bulletin-board systems) in 1984, and on the World Wide Web in 1993 (at a time
`73740602.1
`
`2
`
`
`
`
`
`when the Web held only a few hundred websites); I first began building websites in
`
`1994.
`
`7.
`
`I have extensive experience in the ecommerce arena. In 1997, I founded
`
`Top Floor Publishing to sell Internet-related business books online through
`
`Amazon.com as well as Top Floor Publishing’s own ecommerce store, which I
`
`personally set up myself. I also founded BizBlast, an ecommerce-service provider,
`
`funded by Softbank, one of the world’s largest venture-capital firms. BizBlast
`
`provided small businesses with customized online stores operating on BizBlast’s
`
`servers.
`
`8.
`
`I was also VP of Web Solutions for IC&C, a national ISP (Internet
`
`Service Provider)—my department of around 60 people provided both Web hosting
`
`and Web-development services to a wide range of businesses—and worked as VP
`
`of Marketing for Indigio, a Web-applications development firm with clients such as
`
`Avis, Budget Truck Rental, Budget Rent a Car, and Dex, one of the nation’s largest
`
`Yellow Pages companies.
`
`9.
`
`I have provided consulting services to Amazon, Zillow, Avvo, Tower
`
`Records, Lonely Planet, Honey Baked Ham, and literally hundreds of small and
`
`medium companies, from real-estate agents to travel retailers, lawyers to non-profits.
`
`10.
`
`In addition to my industry background, I have written many books
`
`about the Internet and technology in general. My publications include seven editions
`73740602.1
`
`3
`
`
`
`
`
`of the Complete Idiot’s Guide to the Internet, five editions of Search Engine
`
`Optimization for Dummies, and one edition of SEO for Dummies. I have also written
`
`various books on Web-development and ecommerce issues, including The Official
`
`Netscape JavaScript Book, The Official Netscape JavaScript 1.2 Book, the Official
`
`Netscape JavaScript Programmer’s Reference, and How to Make Money Online
`
`with eBay™, Yahoo!™, and Google™. I also wrote a book titled Poor Richard’s
`
`Web Site: Geek-Free, Commonsense Advice on Building a Low-Cost Web Site.
`
`This book describes in great detail options available to the average business wishing
`
`to create a website, including technology of the time related to ecommerce
`
`(“shopping cart”) websites.
`
`11.
`
`I have also written hundreds of newspaper and periodical articles,
`
`mostly in the area of technology and ecommerce, and have written and presented
`
`four video courses for LinkedIn Learning/Lynda.com (on SEO and selling products
`
`through the Amazon.com marketplace), and one Udemy.com course on SEO (with
`
`22,000 students).
`
`12.
`
`I served as an expert witness in DDR Holdings, LLC v. Hotels.com L.P.,
`
`et. al,1 a district court case related to U.S. Patent Nos. 6,629,135; 6,993,572 (“’572
`
`
`1 DDR Holdings, LLC v. Hotels.com L.P., et. al, 954 F.Supp.2d 509 (E.D. Tex.
`
`2013).
`73740602.1
`
`
`
`4
`
`
`
`Patent”); and 7,818,399 (“’399 Patent). In my role as an expert witness in that
`
`litigation, I provided expert reports regarding both non-infringement and invalidity
`
`for Defendants Expedia, Travelocity, Internetwork Publishing Group [Orbitz],
`
`International Cruise & Excursion [ICE], and Digital River. I understand that by the
`
`time the district court proceeding had concluded, all of the Defendants had settled
`
`except for National Leisure Group, Inc.2 and Digital River. Digital River only had
`
`claims of the ‘572 Patent asserted against it. I testified at trial for Digital River only
`
`about the asserted claims of the ’572 Patent. On appeal, the Federal Circuit analyzed
`
`invalidity over Digital River’s Secure Sales System for the ‘572 Patent only. DDR
`
`Holdings, LLC, v. Hotels.com, L.P., et al., 773 F.3d 1245 (2014). In its decision, the
`
`Federal Circuit reached a conclusion similar to my own, finding the claims of the
`
`‘572 Patent were invalid over Digital River’s Secure Sales System. Id., at 1253.
`
`Additional details regarding my professional experience and publications, and cases
`
`in which I have testified over the last four years, are set forth in my curriculum vitae,
`
`attached as Appendix 1 to this declaration.
`
`13.
`
`I am familiar with the knowledge and capabilities of a person of
`
`ordinary skill in the art (POSITA) in the area of Web page development/design for
`
`electronic commerce and affiliate marketing systems. Specifically, I am familiar
`
`
`2 I did not serve as an expert witness for National Leisure Group, Inc.
`73740602.1
`
`5
`
`
`
`
`
`with the understandings of one of ordinary skill in the art prior to and during the
`
`period in which the ’876 Patent was allegedly invented, and my testimony herein
`
`when referring to one of ordinary skill, and what was known in the art, refers to that
`
`period.
`
`Compensation
`
`14.
`
`I am being compensated at a rate of $550.00 per hour for my work by
`
`the Petitioners for my assistance with their petition for Inter Partes Review (“IPR”)
`
`of the ’876 Patent and, specifically, for my time spent reviewing documents in
`
`association with the IPR and in preparing my testimony. Additionally, I am not, and
`
`have never been, an employee of Petitioners, and my compensation is not dependent
`
`upon the outcome of this proceeding or the opinions that I express.
`
`Technology Background
`
`15. While the overview touches on a number of technology issues, it is out
`
`of necessity that provide only a brief overview in this declaration. I am prepared to
`
`explain these technological principles as they relate to the ’876 Patent in further
`
`detail should I be asked to do so.
`
`16.
`
`In the section that follows, I discuss some of the general principles that
`
`are pertinent to the invalidity of the DDR Patents and of the related art.
`
`A. Historical Evolution of Web-Based Commerce Systems
`
`73740602.1
`
`
`
`6
`
`
`
`17. The modern, public Internet dates to 1993, when the Government began
`
`permitting its commercial use. As the number of Internet users increased, businesses
`
`saw an opportunity to serve them, and by 1994 many new ecommerce companies
`
`were launched, such as CDnow.com.
`
`18. Amazon.com took its first order in 1995, by which time the ecommerce
`
`revolution was well under way. Significantly, 1994/1995 saw the beginning of a
`
`significant ecommerce-service market, in which companies began providing
`
`software products and services to merchants in order to assist them in doing business
`
`online, such as “shopping cart” software, transaction-processing software, and
`
`ecommerce Web hosting.
`
`19. For instance, Viaweb was founded in 1995, providing ecommerce
`
`software and hosting, enabling small merchants to set up ecommerce sites with little
`
`or no technical knowledge. The founder of Viaweb had been inspired by another
`
`company, marketplaceMCI (owned by the telecommunications company, MCI)
`
`which had started operations the year before serving mostly large companies. Both
`
`firms were ecommerce outsourcing companies; that is, a merchant would contract
`
`with these companies to operate the ecommerce systems required to run an online
`
`store on the merchant’s behalf. Many merchants would maintain their own websites
`
`elsewhere, but let the outsource provider manage the more complicated ecommerce
`
`component for them.
`73740602.1
`
`
`
`7
`
`
`
`B.
`
`Ecommerce and Affiliate Marketing Systems
`
`20. Very soon after ecommerce took off on the Internet, entrepreneurs and
`
`merchants realized that applying a very old offline concept to online commerce
`
`would be helpful: that is, paying sales commissions to third parties who generated
`
`sales for a merchant. The concept of a sales commission is a familiar one, and thus
`
`it was a natural extension to pay commissions for online sales. Commonly known
`
`as affiliate marketing (though the world’s largest system, owned by Amazon.com,
`
`actually uses the term associate rather than affiliate), the concept is simple. If
`
`website owner A sends a visitor from his website to the ecommerce site owned by
`
`website owner B, and if that visitor makes a purchase from B’s website, then B pays
`
`A a commission on the sale. A merchant could multiply sales many times by having
`
`affiliates market his products.
`
`21. Affiliate marketing on the Internet dates to at least 1994, when CDnow
`
`launched its first such program. However, some observers argue that online affiliate
`
`marketing really dates to 1989, when PC Flowers & Gifts launched a store on the
`
`Prodigy online network, and paid Prodigy a commission on all sales. In January of
`
`1996, the founder of PC Flowers & Gifts filed for an affiliate-related patent, U.S.
`
`73740602.1
`
`
`
`8
`
`
`
`Patent No. 6,141,666 (“’666 Patent”)3, and in July of that year Amazon.com
`
`launched its affiliate program, which would eventually recruit over a million
`
`affiliates.
`
`C.
`
`Site Cobranding and Design Matching
`
`22. One issue that arose soon after online activities began was that of brand
`
`identification. Web pages have a definitive look and feel, as do physical stores, and
`
`the customer must be given a consistent online experience. If an affiliate sells the
`
`products of many different merchants, it is critical for the customer to believe that
`
`he is shopping at the affiliate, not at the individual stores of multiple merchants.
`
`Otherwise, the affiliate’s identity would be lost. It was therefore common for an
`
`affiliate to display product web pages using the affiliate’s consistent look and feel,
`
`even if the product information was being provided from web servers belonging to
`
`different merchants.
`
`23. Thus, very early on, as companies began splitting functions between
`
`Web servers, they would serve pages having the same design from the various
`
`servers, and when ecommerce service providers began providing hosted ecommerce
`
`
`3 The ’666 Patent was applied in a rejection against claims of the ’399 Patent, to which the ’876
`
`Patent claims priority, and Patent Owner traversed the rejections asserting, in various ways, that
`
`the ’666 Patent did not disclose an outsource provider.
`73740602.1
`
`9
`
`
`
`
`
`services to companies that already had websites, it was clear that customization was
`
`necessary so that visitor to the site would encounter a consistent look and feel. In
`
`addition, the concept of design matching was apparent to companies involved in
`
`affiliate marketing very early on; Company A could sell its products through an
`
`online store that appeared to be on Company B’s website, and pay Company B a
`
`sales commission. Company A could easily operate hundreds, if not thousands, of
`
`customized stores for hundreds or thousands of different websites, and each store
`
`could match the appearance of the associated website.
`
`24. The inventors of the DDR Patents were not the first to come up with
`
`the idea of design matching or providing a consistent online interface or, as the
`
`patents-in-suit describe it, maintaining “look and feel.” For example, as explained
`
`below, certain claims of the ’572 Patent, of which the ’876 Patent is a continuation,
`
`were found by the Federal Circuit to be anticipated over Digital River’s Secure Sales
`
`System (DR SSS). Digital River was in the business of managing software sales and
`
`software downloads for software publishers, wholesalers, and retailers and its DR
`
`SSS was publicly operating at least as early as April 1997. The DR SSS is an
`
`outsource ecommerce system that provides all ecommerce functions for the sale of
`
`software. Links from a software publisher’s website would point to pages on the
`
`DR SSS server. Clicking one of these links would load a page from the DR SSS
`
`server into the visitor’s Web browser, but, as the pages are customized to match the
`73740602.1
`
`10
`
`
`
`
`
`referring site, visitors would be unaware that the new pages were, in fact, coming
`
`from a separate ecommerce server. Digital River advertised, and a person of
`
`ordinary skill in the art would have understood, that the DR SSS enabled “the entire
`
`transaction [to] take[] place in the selling environment you’ve created, surrounded
`
`by the look and feel of your identity, with your products presented the way you want
`
`them presented . . . customers simply hit the purchase icon at your site and the whole
`
`process unfolds smoothly. There’s no sensation of being suddenly hustled off to
`
`another location.” December 1997 Website.
`
`25.
`
`In fact, the inventors of the DDR Patents appear to have derived their
`
`idea, at least in part, from a company called e-Merchant Group, Inc. For example, I
`
`have reviewed a document titled “MicroShopsTM Business Plan”, which references
`
`two of the inventors named in the DDR Patents (i.e., Delano Ross, Jr. and Joseph
`
`Michaels) on the first page. I understand that MicroShops was a predecessor system
`
`to the Nexchange system disclosed in the ’876 Patent. The MicroShops Business
`
`Plan identifies e-Merchant Group as a competitor and describes e-Merchant Group’s
`
`system as follows, as:
`
`e-Merchant Group’s technology creates a mall-like template that
`allows various merchants and manufacturers to sell their
`products within a consistent online interface. Websites that wish
`to create a private label store can select from e-Merchant
`Group’s list of merchant clients and build a customized, co-
`branded store by e-Merchant Group. e-Merchant Group can
`handle all order and payment processing, including credit card
`73740602.1
`
`11
`
`
`
`
`
`transactions, and can even take responsibility for warehousing
`and order fulfillment through e-Merchant Group partners.
`
`In many ways, e-Merchant Group offers a very similar service to
`that offered by MicroShopsTM. The company’s private label
`stores concept bears great similarity to MicroShopsTM and the
`value propositions they present to merchants and manufacturers
`closely resemble those offered by MicroShopsTM. However, e-
`Merchant Group has built an extremely limited number of
`private label stores and has chosen to focus only on merchants
`with two industries: toys and outdoor gear.4
`D. Outsourced Web Hosting and Ecommerce Hosting
`
`26. At the time of the alleged invention, hosting merchant sites on an
`
`outsourced Web server was not novel; it was quite simply the norm. That is, the vast
`
`majority of companies had their websites, and the ecommerce functions of their
`
`websites, hosted by third-party, outsource companies known as Web-hosting
`
`companies and ecommerce hosting companies. This was necessary because most
`
`companies simply did not maintain their own server farms.
`
`27. The use of outsourcing companies was not well known to one skilled
`
`in the art by early 1997—the first Web-hosting companies date to at least 1994—but
`
`was the most common way of setting up a website. Relatively few companies set
`
`up and managed their own Web servers, for either basic informational sites or for
`
`more complicated, transactional, ecommerce sites, because of the resulting expense
`
`
`4 Appendix 2 - MicroShopsTM Business Plan, at 46-47.
`73740602.1
`
`12
`
`
`
`
`
`and complexity. It was—and remains to this day—simpler and cheaper to outsource
`
`these functions. In fact, it was well known in 1997 that setting up an ecommerce
`
`site was “a huge pain in the butt” (see Digital River Brochure, at page 2), and thus
`
`should be left to the experts.
`
`28. Ecommerce hosting began at least as early as July, 1995, as can be seen
`
`from the original business plan for Viaweb,5 and was well known and widely
`
`available by early in 1997. For instance, one ecommerce-software developer, iCat,
`
`announced in April 1997 that it was working with 250 partner “Web development
`
`and Internet hosting companies”; that is, companies using its software to outsource
`
`ecommerce functions for businesses wishing to sell products online.6
`
`29.
`
`In 1996 and early in 1997, I wrote a book called Poor Richard’s Web
`
`Site: Geek-Free Commonsense Advice on Building a Low-Cost Web Site. This
`
`book explained to companies wishing to do business online just how to do that, based
`
`on my experiences since late 1993.
`
`

`
`6 https://www.thefreelibrary.com/iCat+Electronic+Commerce+Suite+3.0+ships-a019351856
`73740602.1
`
`13
`
`
`
`
`
`30. On January 31, 1997, I sent a chapter to the initial publisher (Que
`
`Computer Books7) titled Where to Put Your Web Site. This chapter contained
`
`various options, but I warned my readers that they should not set up their own Web
`
`server but rather should use the services of an outsource company—a Web-hosting
`
`company. (“If you don’t know what it takes to set up a Web server, don’t try it! . . .
`
`It’s obvious by now which method I think is the most suitable in most cases: you
`
`should set up a site with your own domain name at a Web-hosting company.”)
`
`31. Another chapter, titled “Taking Orders Online,” advises readers to set
`
`up “shopping cart” software, and states: “Your Web-hosting company may already
`
`have such a system available for use. They may be using one of the free CGI scripts,
`
`or perhaps have an arrangement with a company, such as WebMate, that is licensing
`
`shopping-cart software to Web-hosting companies and ISPs.” It also explains that
`
`businesses could find their own ecommerce software and install it on their Web
`
`server, which the book recommended should be an outsourced Web server.
`
`32. The book also listed a number of shopping-cart systems readers could
`
`use. One, for instance, was a system named ShopSite Manager. The publisher of
`
`this software, iCentral, provided hosting services for companies wanting to
`
`
`7 Although originally planned for publication by Que, the book was eventually
`
`published by my own publishing company, Top Floor Publishing.
`73740602.1
`
`14
`
`
`
`
`
`outsource the creation and management of their shopping-cart systems (“We offer
`
`hosting for ShopSite software merchants. Everything you need for your site,
`
`including web site development and technical support.”8) The company claimed that
`
`by September 26th, 1996, it was already hosting ecommerce sites for “over 200
`
`merchants.”9
`
`33.
`
`It was common by 1997 for companies setting up online stores to work
`
`with two outsourcing companies; one to host their primary, informational website
`
`and one to host the ecommerce portion of the site. For instance, in November, 1996
`
`Amnesty
`
`International opened
`
`its online store hosted by ViaWeb
`
`(at
`
`http://www.ishops.com/aipubs/).10 However, Amnesty International hosted its
`
`primary, informational website, elsewhere, on the Amnesty.org domain name.11
`
`34.
`
`It was natural for companies to split their sites between informational
`
`and shopping-cart sites, due to the complexity of setting up and managing shopping-
`
`cart sites. However, many companies wanted all their Web pages, whether on a
`
`

`73740602.1
`
`15
`
`
`
`
`
`simple Web-hosting outsource server or on the shopping-cart outsource server, to
`
`appear to be hosted on a single site.
`
`35. For example, Aardvark Cycles had a website identified using the
`
`domain name AardvarkCycles.com12; however, it also set up a store hosted by
`
`iCentral on the ShopSite.com domain in 199613. The company had the same logo
`
`on both sites14; the underlying code of these archived pages shows that both sites
`
`contained an image, below and to the right of the logo, named ad.fiber.jpg; both had
`
`a smaller logo in the top-left corner of the page, little.bluelogo.125.gif; both had the
`
`same navigation links on the left side of the page (on the ShopSite.com server
`
`pointing back to the AardvarkCycles.com server); both had the same footer text and
`
`links at the bottom of the page; both used the same background image (blueback.gif);
`
`and so on.

`
`
`
`36. The DDR Patents use a variety of Web-design terms that merit
`
`explanation.
`
`HTML
`
`37. The DDR Patents describe the use of HTML to create Web pages.
`
`HTML (HyperText Markup Language) is a human readable coding language with
`
`which a Web designer can create Web pages. When a Web browser loads a Web
`
`page, it loads the HTML “instructions” that tell the browser how to display
`
`(“render”) the Web page and include such information as the background color of
`
`the page, the text that will appear in the page, the color of the text and the typeface
`
`used, where images should be placed, a background image or a background color for
`
`the Web page, and so on. It is a set of instructions to the browser that describes the
`
`“page layout.”
`
`38. By the time of the alleged invention of the DDR Patents, the use of
`
`HTML was well understood by Web designers; indeed, it was not possible to create
`
`Web pages without an understanding of HTML. Furthermore, the idea of re-using
`
`HTML code from one page on other pages within the same website—or even on
`
`different websites—was not a novel concept or difficult task; rather, it was
`
`something that any Web designer could and routinely did implement.

`
`39.
`
`It was common in Web development at the time of the alleged invention
`
`of the DDR Patents, and remains so today, for a Web page to have a “header” and a
`
`“footer.” (In fact, it is more common for Web pages to contain these features than
`
`not to contain them.)
`
`40. The term “header” refers to the top portion of a Web page, which
`
`typically contains the name of the website or the company that owned the website;
`
`a company logo (usually either centered in the middle of the header or on the left of
`
`the header); and other components such as a phone number and contact email
`
`address. The header also frequently contains several links to other pages within the
`
`site; this collection of links is known in the Web-design business as a “navbar”
`
`(navigation bar).
`
`41. The term “footer” refers to the bottom portion of a Web page, which
`
`frequently contains elements such as a copyright notice, more links to Web pages
`
`within the site, perhaps links to other websites owned by the site owner or partner
`
`sites, contact information, and so on.
`
`42. Headers and footers were typically “site-wide.” That is, a Web designer
`
`would create one header layout and one footer layout, and then use the same layout
`
`on all pages within the site; regardless of which page in the site a visitor was viewing,
`
`he or she would see the same information at the top and bottom of each page, and
`
`73740602.1
`
`
`
`18
`
`
`
`would be provided with the same “navigation” options, thus creating a consistent
`
`look and feel.
`
`43. Any Web designer would have known how to create a header and a
`
`footer that could be used on all the pages of the website, or even on different
`
`websites.
`
`Navigation Links
`
`44.
`
`In several claims, the DDR Patents refer to “navigation links.”
`
`45. The World Wide Web (WWW) is based on the use of “hyperlinks”
`
`(also known as “links”) to assist users in loading pages; the WWW is a “web” of
`
`pages linked together. In fact, it is the hyperlinks that create the “web” by allowing
`
`a user to move from one page to another by clicking links. A link is a mechanism
`
`by which a Web designer can associate one page with another, and by which a user
`
`may view the referenced page. Links are most commonly “activated” through the
`
`use of a computer mouse; the user points at a link in a Web page and clicks the
`
`mouse button to because the browser to request and load the referenced page.
`
`46. Links can be with associated various different objects within a Web
`
`page (that is, different objects may be “hyperlinked”). A link may be associated
`
`with an image displayed within the page, or on a piece of text—one or more words—
`
`within the page. (These are the two most commonly “linked” elements in a Web
`
`page, though links may be added to other objects, such as videos.) So, for example,
`73740602.1
`
`19
`
`
`
`
`
`the Web designer creating Page X could put a link on an image in that page
`
`referencing Page Y; a user viewing Page X may point at the image and click the
`
`mouse button to load Page Y.
`
`Left-Hand Navigation
`
`47.
`
`It was very common at the time of the alleged invention of the DDR
`
`Patents to have a “left-hand navbar”; that is, a collection of links in a box on the left
`
`side of Web pages, effectively serving as a table of contents. This collection of links
`
`was typically placed onto all the various Web pages within a website. The links in
`
`the navbar would typically be used by site visitors to load different areas of a website
`
`and commonly needed Web pages, such as a Contact Us page, an About Us page,
`
`and so on. A left-hand navbar would likely be considered a primary element to carry
`
`over if one were to design a Web page to maintain the appearance of another website.
`
`Company Logos
`
`48.
`
`It was common in Web development at the time of the alleged invention
`
`of the DDR Patents, and remains so today, for Web pages owned by companies to
`
`include the company logo image at the top of the Web page, in the page header. This
`
`logo would typically be in the middle of the header, or on the left side of the header.
`
`49. The company logo itself was frequently “hyperlinked”; that is, using
`
`the HTML code that formats the page, a hyperlink was associated with the logo
`
`image, so that when a visitor to the website pointed at the logo with his or her mouse
`73740602.1
`
`20
`
`
`
`
`
`pointer and then clicked the mouse button, the Home page (the main page) of the
`
`website would be loaded into the browser.
`
`Web Page Data Storage
`
`50. A Web page is created through the use of computer files; typically an
`
`HTML file (which is a form of text file containing the HTML instructions), perhaps
`
`Cascading Style Sheet files (text files containing more sophisticated page-layout
`
`instructions) and JavaScript files (text files containing programming instructions for
`
`interactive Web pages), graphic-image files for the pictures within the Web page,
`
`and so on. (At the time of the alleged invention of the DDR Patents Cascading Style
`
`Sheet files and JavaScript files were available but not frequently used.)
`
`51. The DDR Patents refer to the storage of these files. When a user
`
`requests a Web page (by entering the page address—the URL—into a Web browser
`
`or by clicking on a link referencing the page), a message is sent to the Web server
`
`that hosts the Web page. The Web server retrieves the HTML file from its storage
`
`and sends this page to the user’s browser.
`
`52. The user’s browser then reads the file. If the file references other files,
`
`then the browser requests them from the server, also. For example, perhaps the
`
`finished Web page (the “rendered” page, as it is known in the industry) will contain
`
`a composite of text and several images. The individual components do not need to
`
`come from the same Web server. The HTML will contain references to those
`73740602.1
`
`21
`
`
`
`
`
`images, instructions telling the browser where the images are stored and where they
`
`should be placed on the Web page. The browser will request those images from the
`
`Web server, and on receipt will insert the images into the Web page that is displayed
`
`in the user’s browser window.
`
`53. While all these files—the original HTML file and the associated image
`
`files—are often stored on hard-drive data storage inside the Web-server computer,
`
`or on hard-drive data storage connected to the Web-server computer, this is not
`
`always the case. One or more of those images, for instance, could be stored on a
`
`completely separate computer, perhaps in a completely different area of the world.
`
`(This is typically the case with advertising in Web pages; the images are loaded from
`
`a Web server owned by the advertising company; not the server, owned by the Web-
`
`site owner, that delivered the HTML file to the server.)
`
`Web-Based Ecommerce and Shopping Cart Technology
`
`54. By the time of the alleged invention of the DDR Patents, Web-based
`
`ecommerce and shopping-cart technology had been in use for several years. Online
`
`commerce, on networks other than the World Wide Web, dates to as early as 1979,
`
`73740602.1
`
`
`
`22
`
`
`
`and on the Internet to as early as 1994 (both Books.com and CDNow.com launched

`in tha
