Grid of Icons
Mr. Lucente next claims that “[a] grid of icons is functional because it serves as an
3
organizational structure that allows a user to see and understand information quickly.” (Lucente
4
Report at 16.) Mr. Lucente even claims that an icon grid is “fundamental.” (Id.) I disagree with
5
Mr. Lucente because an icon grid is not required for a GUI to function. As shown in Exhibit 10
6
of my Opening Expert Report, there is a wide variety of icon arrangements that are used in
7
smartphones. Thus, the particular icon grid arrangement shown in the D’790 Patent is not
8
required or dictated by function, as there are other ways to organize user interface elements on a
9
rectangular screen.
10
27.
Mr. Lucente further claims that the spacing of the icons in the D’790 Patent is
11
functional because it allows for a user to select only one icon at a time using a human finger, a
12
human hand with a stylus, or a human hand with a mouse, and that the specific rows and columns
13
shown in the D’790 Patent design are a function of the size of the screen and number of icons
14
displayed. (Lucente Report at 16-17.) I disagree with Mr. Lucente on both points.
15
28.
First, when Mr. Lucente refers to “the spacing of icons” in the D’790 Patent, he is
16
referring to the rounded rectangle elements, which are containers for icons, not necessarily icons
17
themselves. As discussed further in paragraph 35, below, the function of those containers being
18
selectable (with a finger, stylus, or a mouse) depends on the area of the physical screen
19
designated as the “hit area” for the containers, which is not necessarily the same as the area of the
20
container itself. Accordingly, that function does not dictate the spacing between the containers
21
(or, by extension, the spacing between the icons within the containers). The Blackberry Storm 2
22
and Nokia N9 (Figures 2 and 3, below) show how the spacing of elements on a touch screen is
23
not dictated by the function of being selectable. In both figures, graphic containers analogous to
24
the rounded rectangles in the D’790 Patent are within, but do not necessarily define the
25
boundaries of, separate selectable areas on the screen. In the Blackberry Storm 2, however, the
26
square “badges” containing the icons have almost no space separating them, whereas in the Nokia
27
N9 the icons are contained in much smaller, nearly circular shapes that have noticeable empty
28
space between them. It is an ornamental decision whether to adopt minimal spacing between icon

containers, as in the Blackberry Storm 2, as opposed to having more space between the

Second, as noted above, the proportions of the rectangular shape of the display
16
screen are not dictated by function. Accordingly, even if Mr. Lucente were correct that the size
17
of the screen dictated the specific rows and columns in the D’790 Design, that does not mean that
18
the “rows and columns in a grid are functional,” as Mr. Lucente claims, because the number of
19
rows and columns could be altered by changing the dimensions of the screen. (Lucente Report at
20
16.) Exhibits 6 through 13 of my Opening Expert Report are a sampling of the many possibilities
21
for utilizing an icon grid in ways that result in noticeably different visual impressions. These
22
examples demonstrate that the particular appearance of the icon grid in the D’790 Design is not
23
required or dictated by the functions Mr. Lucente identifies.
24
30.
Mr. Lucente’s remaining commentary about the D’790 Patent is either irrelevant
25
or misguided. He notes that the difference in vertical versus horizontal spacing between the
26
squares in the grid is functional “because it allows space for text under the icons.” (Lucente
27
Report at 17.) However, there is no text under the squares in the grid in the D’790 Design, so this
28
purported functionality does not come from the design itself. Mr. Lucente bases his claim on
EXPERT REBUTTAL REPORT OF SUSAN KARE
Case No. 11 cv-01846-LHK
9
1
statements by Imram Chaudhri, which I have been informed is not normally a proper basis for
2
interpreting a patent.
(c)
3
31.
4
Grouping of Icons
Mr. Lucente also relies on the supposed principle that “objects sharing similar
5
attributes, e.g., multiple squares with rounded corners, are perceived as a group.” (Id.) But Mr.
6
Lucente does not explain how those attributes themselves (squares with rounded corners) are
7
anything but one design option for the visual appearance of the icons individually and for the
8
screen overall. There are infinite ways to design objects on a screen so that they are perceived as
9
a group. As the examples in Exhibits 6 through 13 of my Opening Expert Report demonstrate,
10
even if one were to make the design decision to present icons as a group, the use of squares with
11
rounded corners, as in the D’790 Design, or even icons with consistent shapes is not required or
12
dictated by function.
(d)
13
32.
14
Dock of Icons
Mr. Lucente next claims that the “lower four squares with rounded corners” are a
15
“dock of frequently-used icons” and are thus “functional elements.” (Lucente Report at 17.) I do
16
not see anything in the D’790 Patent that refers to or requires this alleged functionality of the
17
bottom row of icons.19 Mr. Lucente’s sole basis for reading this functionality into the patent is
18
the testimony of Mr. Chaudhri, who testified about the design of the iPhone as it related to the
19
D’790 Patent. I have been informed that it is not normally proper to rely on inventor testimony. I
20
have also been informed that the design as shown in the patent itself, and not products that may
21
embody the design, is the proper basis for evaluating a design patent. Because the D’790 Patent
22
itself does not indicate one way or another how the bottom row of icons would actually function
23
in a GUI, there appears to be no basis for Mr. Lucente’s conclusion.
33.
24
Moreover, even if Mr. Lucente as correct that the bottom row of squares in the
25
D’790 Design represents a “dock of frequently-used icons,” that would not mean that the design
26
element in the D’790 Design is merely functional. There is no functional requirement that such a
27
19
28
For convenience, I have used the term “dock” to refer to the bottom row of icons. This is simply to make clear that
I am referring to the same design element that Mr. Lucente is referring to and is not an adoption of Mr. Lucente’s
position on that element’s function.
EXPERT REBUTTAL REPORT OF SUSAN KARE
Case No. 11 cv-01846-LHK
10
1
dock must use rounded rectangle shapes or elements with a similar shape and size as the other
2
elements in the design. Exhibits9 (examples C, F, G, H, F20) and 13 of my Opening Expert
3
Report contain multiple examples of screens with “docks” that do not follow the visual approach
4
of the D’790 Design. In these examples, the items in the row at the bottom of the screen
5
noticeably depart from the graphical styles used in the icons elsewhere. These examples
6
demonstrate that even if one makes design choice to have a single grouping of “frequently-used
7
icons” at the bottom of the screen, that functional concern does not require, or dictate, the
8
appearance of the separate row of icons in the lower portion of the screen in the D’790 Design.
9
(e)
10
34.
11
Shape and Size of Icons
Mr. Lucente claims that the spacing, proportions, shape, and number of the squares
12
in the D’790 Patent are functional. Regarding size and shape, Mr. Lucente says they are
13
functional “because the consistent size and shape conveys the form of a selectable button and
14
communicates that the icons share similar attributes so that they perceived [sic] as a group.”
15
(Lucente report at 18.) But this would be true of any consistent size and shape and says nothing
16
about the visual appearance of the D’790 Design or the particular design choice to use consistent
17
rounded rectangles. Various examples demonstrate this. The Nokia N9, shown in Exhibit 12 of
18
my Opening Expert Report and above in Figure 3, shows icons set inside consistent shapes (with
19
four rounded sides) that clearly read as a group of “buttons.” The Blackberry Storm 2, shown in
20
Exhibit 8 of my Opening Expert Report and above in Figure 2, has icons set on square badges,
21
each clearly reading as a separate button while also being part of a clear grouping of icons. In
22
Exhibits 6 and 7 of my Opening Expert Report, the icons themselves have different shapes and
23
are not presented on a set of identical background containers, but they have consistent
24
perspectives and clearly read as a group of buttons. Obviously, a desire to present icons as a
25
group does not dictate a particular GUI appearance or the particular appearance of the D’790
26
Design.

In the phone labeled “F” in Exhibit 9 of my Opening Expert Report, the dots along the bottom of the screen are
labeled “dial,” “phonebook,” “messages,” and “widgets.” (See Exhibit 2).

Case No. 11 cv-01846-LHK

35.
Regarding the relative size of the squares, Mr. Lucente says it is functional
2
“because the relative size allows a person to see the icon and a human finger better to select the
3
icon.” (Lucente Report at 18.) However, icons or icon containers, such as the rounded rectangles
4
in the D’790 Patent, are not necessarily the same size as the “hit area” (the “selectable” or
5
“tappable” area on a screen) associated with the icons or icon containers. Accordingly, the icon
6
containers shown in the D’790 Patent could be larger or smaller without affecting the user’s
7
ability to activate the underlying application; that functionality is provided anywhere within the
8
“hit area,” which can be a different size than the icon or icon container. This fact is demonstrated
9
on devices such as the Pantech Hotshot and Sony Ericsson Experia arc S, which have icons that
10
can be selected by touching the screen within an area that contains, but is considerably larger
11
than, the icon images themselves. As shown in Figures 4 and 5, this fact is easily demonstrated
12
using a stylus to select the icons by touching the screen in the area outside of each icon21:

In Figures 4 and 5, the highlighted rectangle around the icon corresponds to the area that can be touched by a stylus
or a finger to select that icon. For the pictures shown in Figures 4 and 5 and Exhibit 3, a stylus (a pen with a metallic
body and a foam tip on the non-writing end) was used for clarity. The same effect shown in Figures 4 and 5 can be
demonstrated on other devices, including the Nokia N9 and the iPhone Devices. The Pantech Hotshot and Sony
Ericsson arc S were used here as examples because the visual effects when an icon is selected on those devices are
particularly clear.

Figure 5

12
(See also Exhibit 3.) Likewise, in the D’790 Patent, the size of the rounded rectangle shapes
13
could be much smaller—possibly even minuscule—without changing the selectable area
14
associated with the icon. The size of the icons or icon containers themselves is thus not dictated
15
by the function of being selectable by a human finger. The choice of icon or icon container size
16
is an ornamental design decision.
36.
17
Even if the size of each icon or icon container were required to be identical to a
18
selectable area on the screen, Mr. Lucente does not show how that dictates the size of the rounded
19
rectangles in the D’790 Patent. Mr. Lucente cites a study that reports 9.2mm as the minimum
20
button size for “discrete tasks” (defined as including “activating buttons, radio buttons and
21
checkboxes”) “without degrading performance and preference.” (See Lucente Report at 18 fn.
22
46.) Mr. Lucente says that the “icons depicted in the D’790 Patent align to these targets,” but he
23
does not explain what that means. (Id. at 18.)
37.
24
The D’790 Patent contains one figure, and the rounded rectangles in that figure
25
measure approximately 14mm across, much larger than the 9.2mm reported in the cited study.22
26
To the extent that Mr. Lucente meant to refer to the iPhone display, that is an irrelevant
27
22
28
I have been informed that drawings in patents are not interpreted as representing absolute sizes of the claimed
design. The D’790 figure is more than 18cm tall and is obviously not intended to represent any absolute size for the
claimed GUI appearance.
EXPERT REBUTTAL REPORT OF SUSAN KARE
Case No. 11 cv-01846-LHK
13
1
comparison under the law as explained to me by counsel. Moreover, I have been informed that if
2
the drawing were scaled down so that size of the display screen matched the size of the iPhone
3
screen, the rounded rectangles would be approximately 8.4mm x 8.4mm, nearly 10 percent
4
smaller in each dimension than the 9.2mm minimum reported in the cited study.23, 24 Thus, even
5
accepting the premise that there is a minimum “target size” for buttons on a display to function,
6
the size of the rounded rectangles in the D’790 Patent either far exceeds the minimum size that
7
Mr. Lucente claims is required for them to function (using the absolute size of the printed patent),
8
or is smaller than that minimum size (using the patent drawing scaled down to the size of an
9
iPhone). These facts do not support Mr. Lucente’s conclusion that the size of the rounded
10
rectangles is dictated by there being an optimal “target size,” and I know of no other support for
11
Mr. Lucente’s conclusion.
12
38.
Moreover, mobile phone devices on the market demonstrate that icons can
13
function as buttons in a touch screen GUI even when they are smaller than 8.4mm (the size of the
14
squares in the D’790 Patent scaled down relative to the iPhone screen). The Nokia N9, for
15
example, has icons that are less than 8mm x 8mm, and the Pantech Hotshot has icons that are less
16
than 7mm x 7mm.
(f)
17
18
39.
Number of Icons
Mr. Lucente also claims that “the number of the icons is functional because the
19
number is determined by the overall area of the rectangular outline, the size of the icon, shape of
20
the icon, the spacing of the icon in the grid and the number of icons desired by the user and/or the
21
manufacturer.” (Lucente Report at 18 (emphasis added).) With respect to the first four factors
22
listed, Mr. Lucente is simply saying that the number of icons depends on other design elements.
23
As explained above, the functions that Mr. Lucente assigns to those design elements do not
24
23
25
26
27
28
The calculation provided to me, at my request, is as follows: the ratio of the iPhone screen size (3.5 inches, or
8.89cm, diagonal) to and the size of the display in the printed D’790 Patent (approximately 14.8cm, diagonal) is
approximately .6:1 (8.89/14.8:1), so scaling the 14mm-wide squares in the printed D’790 Patent down to the relative
size of the actual iPhone would result in squares 8.4mm wide (14mm x .6 = 8.4mm).
24
It is also unclear how the Apple iOS Human Interface Guidelines relate to Mr. Lucente’s conclusions. He states
that the guidelines specify a “comfortable minimum size of tappable UI elements,” but he does not analyze whether
the rounded rectangles depicted in the D’790 Patent correspond to and therefore may have been “dictated by” that
minimum size.

Mr. Lucente also concludes that the status bar—the row containing status
13
indicators at the top of the screen in the D’305 Design—is a “merely functional” element,
14
although he does not even attempt to argue that the visual appearance of the status bar in the
15
D’305 Design is primarily dictated by any function. (Lucente Report at 20) In fact, just as Mr.
16
Lucente concedes that certain details of the icon dock “could be an ornamental choice” (id.), the
17
particular appearance of the status bar is an ornamental choice. Mr. Lucente’s own alleged prior
18
art examples reveal the many different ornamental designs that a status bar could use, including
19
more colorful status bars with varying thickness and a status bar that appears at the bottom of a
20
screen instead of the top. (Id. at 41, 53-56, 62-63.) Moreover, the status bar in the D’305 Design
21
does not play a significant role in creating the overall appearance of the design, so even if its
22
appearance were entirely determined by function, that would have little relevance to whether the
23
overall appearance of the D’305 Design is dictated by function.
24
45.
Mr. Lucente also concludes that the icons in the D’305 Patent “are functional
25
because they are metaphors for the function the user wishes to access.” (Lucente Report at 21.)
26
At no point in his report does Mr. Lucente consider the fact that icons, including those shown in
27
the D’305 Patent, can have unique visual appearances. Instead, Mr. Lucente concludes that
28

Case No. 11 cv-01846-LHK
17

123.
Mr. Lucente also presents a series of GUI interfaces that he alleges “can serve as
2
secondary references of obviousness for the rounded square design feature, as well as other
3
features, such as the use of a status bar and arrangement of icons in a grid pattern.” (Lucente
4
Report at 59.) Korean Patent 30-2006005195 displays a group of rectangles on an angled plane
5
seen in perspective, giving them a substantially different appearance than the rounded squares in
6
the Design Patents. In European Community Design Registration No. 000505532-0001, the
7
image presented by Mr. Lucente is very low resolution. Nevertheless, the rectangular shapes
8
appear to have an effect that makes them appear as three dimensional frames as opposed to
9
simple rounded rectangles like the ones in the D’790 Design. Korean Design Patent 30-0403504
10
has rectangles that read as squares with sharp corners, although the corners along the outside of
11
the grid do appear to be slightly rounded. Japanese Design patent D1189312 displays cube-
12
shaped icons that do not read as individual rounded rectangles. Also, none of these references,
13
the Nokia N7710, or U.S. Patent Application Publication 2007/0067738 have an overall
14
appearance that is substantially the same as any of the Claimed Designs. Furthermore, even
15
though Mr. Lucente claims that these references could be used as “secondary references,”
16
nowhere in his report does he suggest how visual elements of the references could be combined
17
with a particular primary reference to create the overall visual appearance of any of the Claimed
18
Designs.
19
124.
Mr. Lucente also presents 13 examples of a “status bar or region at the top of the
20
display.” (Lucente Report at 62.) These examples merely demonstrate that there is a variety of
21
options for the appearance of a status bar:

24
None of the examples Mr. Lucente presents has substantially the same appearance as the status
25
bars in the D’305 and D’334 Designs, and most of them are markedly different. Mr. Lucente
26
does not suggest any way in which the examples he provides could be combined with a primary
27
reference to create substantially the same overall visual appearance as the D’305 or D’334
28
EXPERT REBUTTAL REPORT OF SUSAN KARE

Design.39 Moreover, the status bars in the D’305 and D’334 Designs do not play a major role in
2
creating the overall appearance of each design, so even if its exact appearance was present in the
3
prior art, that would have little significance in showing that the overall appearance of each design
4
was obvious.
5
125.
Mr. Lucente also presents a long list of “icons using the same metaphors that
6
appear to have been used by Apple in the D’305 and D’334 Patents.” (Lucente Report at 63.)
7
Mr. Lucente has collected icons that appear to use the following symbols: a phone to represent a
8
phone; gears to represent settings; a note pad image to represent notes; an address book and/or
9
silhouette of a person’s head and shoulders to represent contacts; a compact disc and/or musical
10
notes to represent music; a flower to represent photos; a speech bubble to represent text messages;
11
a calendar to represent a calendar; a calculator or calculator buttons to represent a calculator; an
12
envelope to represent mail; a clock to represent a clock; a globe or Earth to represent a web
13
browser; a camera to represent a camera; and a line graph to represent stocks. The list, which
14
contains more than 170 different icons, merely shows that there are many visually distinct ways
15
that icons can represent each of these concepts.40 Mr. Lucente does not argue that any of the
16
icons actually is substantially the same as any of the icons in the D’305 and D’334 Designs, nor
17
does he suggest any specific combination of the icons that would produce an overall appearance
18
that is substantially the same as the D’305 or D’334 Design.
19
126.
Even if it were relevant that certain concepts or symbols (as opposed to particular
20
appearances) were present in the prior art, Mr. Lucente makes multiple errors in identifying those
21
concepts in the prior art. For example, he presents two examples of “photos icons.” (Lucente
22
Report at 71.) As explained above, the Windows Vista icon did not represent a collection of user
23
photographs. (Exhibit 4.) Also, the “Photoshop 2006” icon appears to be a photographic image
24
of a sunflower, not an icon used to represent a collection of user photographs.41 The existence of
25
39
26
27
28
I have been informed that the status bar shown in the D’790 Patent is not part of the claimed design. Paragraph
123 does not concern the D’790 Patent.
40
Although Mr. Lucente refers to the icons as using “common metaphors,” many of the icons feature literal
illustrations, rather than metaphors, to make a concept visual (e.g., a handset image to represent a phone, and a note
pad image to represent a note pad).
41
In fact, this exact photograph is publicly available to anyone under a royalty-free license from PhotoSpin, Inc. (See
Exhibit 7.) Mr. Lucente provides no information to support the assertion that the photograph was used as an icon by
