panning within the document, which have a different purpose than the ’381 patent. Because these
2
references are not concerned with what should happen when the edge of the document is reached,
3
they still embody the main problem that the ’381 patent solved. Users either are not allowed to
4
scroll past the edge (i.e. they hit a “hard stop”) or are allowed to scroll endlessly into empty areas
5
devoid of any content.

In an attempt to dismiss these key differences, Samsung arbitrarily treats the lines
7
within the boundaries of a document in the same manner as external “edges.” It also sets up a
8
demonstration to simulate supposed edge-responsive behavior with software that in fact is merely
9
re-centering items. While that may be easy to do with the ’381 patent already in hand, a person of
10
skill in the art at the time of the invention would not have recognized the edge-responsive
11
advantages of the ’381 patent in Samsung’s prior art.

13.
My declaration begins by showing that Samsung’s alleged prior art was trying to
13
solve a different problem than the ’381 patent, and that it still suffers from the principal
14
limitations and constraints that the ’381 patent was designed to solve. Next, I discuss the faults
15
and shortcomings in Dr. Van Dam’s invalidity and inequitable conduct opinions, concluding that
16
the references he cites do not disclose key elements of the asserted claims or render them obvious.
17
Finally, I address Dr. Johnson’s infringement analysis, which is based on strained claim
18
interpretations that defy common sense.

Summary of Opinion
The ’381 patent provides an elegant and visually intuitive solution to a discrete
22
issue: what to do when a user scrolls to the edge of an electronic document. In the prior art, when
23
a user scrolled to the edge of a document, one of two scenarios would play out. Either she would
24
scroll continuously past the edge of the document into nothingness (i.e. beyond a place where
25
there was any meaningful content), or she would hit a “hard stop” and not be allowed to scroll
26
any further.

Each of these scenarios has its own disadvantages. Allowing a user to move
through virtual space going absolutely anywhere, including beyond a place that has any

I have reviewed the portions of the specification cited by Dr. Johnson. (Johnson

Decl. (D.I. 174) at ¶ 38.) In general, they simply state that a touch screen can display images. A
3
person of skill in the art would understand that such images may or may not contain black. These
4
passages do not show that the inventors adopted an uncommon definition for the common word
5
“display.”
