`
`
`IV. LEGAL STANDARDS
`
`10.
`
`In expressing my opinions and considering the subject matter of the
`
`claims of the ’987 Patent, I am relying upon certain basic legal principles that have
`
`been provided and explained to me.
`
` 4
`
`
`
`
`
`
`
`
`
`A. Relevant Time Period for Unpatentability Analysis
`
`11.
`
`I have been asked to assume the priority date for the claims is April
`
`18, 2012. Therefore, for the purposes of this declaration, I have analyzed
`
`anticipation and obviousness as of that date.
`
`B. Unpatentability by Anticipation and Obviousness
`
`12.
`
`In expressing my opinions and considering the subject matter of the
`
`claims of the ’987 Patent, I am relying upon certain basic legal principles that have
`
`been provided and explained to me.
`
`13.
`
`I understand that a claim is unpatentable as anticipated if all of the
`
`elements of the claim are described or disclosed in a single prior art reference.
`
`14.
`
`It is my understanding also that a patent claim is unpatentable if the
`
`claimed invention as a whole would have been obvious to a person having ordinary
`
`skill in the art (“POSA”) at the time of the invention, in view of the prior art in the
`
`field and analogous fields. I understand that a patent claim can be found
`
`unpatentable as obvious where the differences between the subject matter sought to
`
`be patented and the prior art are such that the subject matter as a whole would have
`
`been obvious at the time the invention was made to a person having ordinary skill
`
`in the relevant field. I understand that an obviousness analysis involves a
`
`consideration of (1) the scope and content of the prior art; (2) the differences
`
` 5
`
`
`
`
`
`
`
`
`
`between the claimed invention and the prior art; (3) the level of ordinary skill in
`
`the pertinent field; and (4) secondary considerations of non-obviousness.
`
`15.
`
`I understand that to prove a claimed invention is unpatentable for
`
`obviousness, it may be useful to understand why a POSA would have been
`
`motivated to combine prior art references.
`
`16. Obviousness may be shown by demonstrating that it would have been
`
`obvious to modify what is taught in a single piece of prior art, or to combine the
`
`teachings of more than one prior art reference, to create the patented invention. In
`
`determining whether a piece of prior art could have been modified or combined
`
`with other prior art or with other information within the knowledge of one of
`
`ordinary skill in the art, the following are examples of approaches and rationales
`
`that may be considered:
`o Combining prior art elements according to known methods to yield predictable
`
`results;
`o Simple substitution of one known element for another to obtain predictable
`
`results;
`o Use of a known technique to improve similar devices (methods, or products) in
`
`the same way;
`o Applying a known technique to a known device (method, or product) ready for
`
`improvement to yield predictable results;
`
` 6
`
`
`
`
`
`
`
`
`
`o Applying a technique or approach that would have been "obvious to try"
`
`(choosing from a finite number of identified, predictable solutions, with a
`
`reasonable expectation of success);
`o Known work in one field of endeavor may prompt variations of it for use in
`
`either the same field or a different one based on design incentives or other
`
`market forces if the variations would have been predictable to one of ordinary
`
`skill in the art; or
`o Some teaching, suggestion, or motivation in the prior art that would have led
`
`one of ordinary skill to modify the prior art reference or to combine prior art
`
`reference teachings to arrive at the claimed invention. I also understand that
`
`this suggestion or motivation may come from such sources as explicit
`
`statements in the prior art, or from the knowledge or common sense of one of
`
`ordinary skill in the art.
`
`17.
`
`I understand that an invention that might be considered an obvious
`
`variation or modification of the prior art may be considered non-obvious if one or
`
`more prior art references discourages or lead away from the line of inquiry
`
`disclosed in the reference(s). For purposes of assessing obviousness, a reference
`
`does not "teach away" from an invention simply because the reference suggests
`
`that another embodiment of the invention is better or preferred. My understanding
`
`of the doctrine of teaching away requires an indication that the combination should
`
` 7
`
`
`
`
`
`
`
`
`
`not be attempted (e.g., because it would not work or explicit statement saying the
`
`combination should not be made).
`
`V.
`
`PERSON OF ORDINARY SKILL IN THE ART
`
`18.
`
`I have been asked to assume the priority date for the claims is April
`
`18, 2012. I have been informed that the priority date may be in dispute in this
`
`proceeding, and Petitioner is asserting that the proper priority date is no earlier
`
`than March 14, 2013. However, my opinions herein remain the same even when
`
`based on a priority date of March 14, 2013.
`
`19.
`
`I believe that a POSA in the field of the ’987 Patent in 2012 would
`
`have been a person with a Bachelor’s degree in Electrical Engineering, Computer
`
`Engineering, or Computer Science (or the equivalent degree) plus approximately
`
`two years of work experience with technologies relating to content annotation
`
`and/or content sharing among multiple users. I also believe that more education
`
`can allow for less work experience and vice versa.
`
`20. By 2012, I had a Ph.D. degree in Computer Science and had been
`
`studying or working in the software industry for roughly 30 years. As such, I was
`
`qualified as at least a POSA, and I have had a sufficient level of knowledge,
`
`experience, and education to provide an expert opinion in the field of the ’987
`
` 8
`
`
`
`Patent.
`
`
`
`
`
`
`
`21. My opinions below are based on the perspective of a person of
`
`ordinary skill in the art at the time of the assumed date referenced therein. I have
`
`taught and worked on projects, which practiced the technology at issue for the ’987
`
`Patent, with a number of students and professionals, both in Universities and in the
`
`computer industries, who would have qualified as a POSA.
`
`VI. CLAIM CONSTRUCTION
`
`22.
`
`I have generally applied the plain and ordinary meaning of the terms
`
`recited in the claims, as would have been understood by persons of skill in the art
`
`in 2012.
`
`VII. SUMMARY OF OPINIONS
`
`23. Based on the materials that I have reviewed, the analysis I have
`
`performed, and the positions I have summarized within this report, I have formed
`
`at least the following opinions listed below.
`
`24. Claims 1-4, 11, 12, 15-18, 20, 23, 25, 26, and 30 are unpatentable as
`
`anticipated by U.S. 2009/0300475 (“Fink”).
`
`25. Claims 1-4, 11, 12, 15-18, 20, 23, 25, 26, and 30 are unpatentable as
`
`obvious over Fink and U.S. 2011/0112915 (“Geer”).
`
`26. Claim 5 is unpatentable as obvious over Fink (or Fink and Geer) and
`
`U.S. 7,809,802 (“Lerman”).
`
` 9
`
`
`
`
`
`
`
`
`
`27. Claim 7 is unpatentable as obvious over Fink (or Fink and Geer) and
`
`Michael Miller, YouTube for Business (“Miller”).
`
`28. Claim 19 is unpatentable as obvious over Fink (or Fink and Geer) and
`
`U.S. 2007/0263984 (“Sterner”).
`
`29. Claim 24 is unpatentable as obvious over Fink (or Fink and Geer) and
`
`U.S. 2013/0004138 (“Kilar”).
`
`30. Claim 27 is unpatentable as obvious over Fink (or Fink and Geer),
`
`Lerman, and Sterner.
`
`VIII. THE ’987 PATENT
`A. Background
`
`31. Consumer DVD editing/burning software, such as Ulead DVD
`
`MovieFactory, was available as of 2002 which allowed users to produce custom
`
`DVDs from their own videos, such as home movies. Ex. 1013, pp. 1 (user guide
`
`dated Nov. 2002), 2 (2002 copyright date), 4. This software possessed
`
`functionality that allowed users to add chapter information for these videos in the
`
`same manner as in commercial DVD movies, thereby allowing viewers to more
`
`easily find a desired portion of the movie to watch:
`
`Add/Edit chapters
`…
`[E]ach chapter is like a bookmark for a video clip. Viewers
`can easily select a chapter then the video clip will
`
`10
`
`
`
`
`
`
`
`immediately jump to the first scene of that chapter and
`start the playback. This feature is particularly useful when
`you want to attract your viewers by giving them the
`freedom to choose a particular part of the movie to watch.
`…
`Creating or editing chapters linked to a video clip:
`1 Select a video in the Media clip list.
`2 Click Add/Edit Chapter.
`3 … drag the Jog Bar to move to a scene as the first frame
`of a chapter, and then click Add.
`
`Ex. 1014, p. 12.
`
`Editing menus:
`…
`2 Click “My Title” to customize the menu heading. You
`can also click the text description under each video
`thumbnail for customization.
`
`Id., p. 13.
`
`32. Moving forward in time, by 2008-2009, the YouTube website already
`
`possessed an annotation feature that allowed users to add annotations to their
`
`uploaded videos at specified intervals of the video. Ex. 1015, p. 16. Such
`
`annotation functionality in YouTube provided users with the ability to “add
`
`interactive commentary to … videos” such as “add[ing] background information,
`
`crea[ting] branching stories, or add[ing] links to any YouTube video … at any
`
`11
`
`
`
`
`
`
`
`point in your video.” Id.; see also id., pp. 86-88 (user “insert[s] commentary” to
`
`the video by “by adding speech bubbles, notes, and highlight boxes anywhere”
`
`desired), 256 (“Annotations can be used to embed clickable text boxes within a
`
`video frame itself”). This functionality in YouTube also allowed a user to “edit
`
`start/stop times” of the annotations and, again, “add links” in each annotation. Id.,
`
`pp. 86-88.
`
`B.
`
`’987 Patent
`
`33. The ’987 Patent states that it “relates to video distribution and media
`
`players.” Ex. 1001, 1:17-18.
`
`34. The ’987 Patent states that a website may receive and store user-
`
`uploaded videos (e.g., product reviews) and make these videos “available to all
`
`viewers.” Id., 20:41-44, 23:29-33. The website also receives and stores a “product
`
`tag” from a user, which is associated with a “reviewed product” and may include
`
`“words or phrases” or “pictures”. Id., 21:32-55. For example, in the context of a
`
`video of a product being reviewed, a user may create a tag to “describe[] … the
`
`reviewed product and/or their feelings regarding the reviewed product.” Id.,
`
`21:35-38. A user may also upload images of products that have been tagged. Id.,
`
`8:36-47.
`
`35. These tags, including uploaded images, may be “displayed during
`
`video playback,” “appear … as the video proceeds,” and “change during playback
`
`12
`
`
`
`
`
`
`
`as different products are discussed.” Id., 12:19-26. These tags may be displayed at
`
`various spatial locations within the video player, such
