Claim Construction
A.
Legal Standard
The construction of a patent is a matter of law for the
Court.
(1996).
Markman v. Westview Instruments, Inc., 517 U.S. 370, 372
“It is a ‘bedrock principle’ of patent law that 'the
claims of a patent define the invention to which the patentee is
entitled the right to exclude.’”
Phillips v. AWH Corp., 415 F.3d
1303, 1312 (Fed. Cir. 2005) (en banc) (quoting Innova/Pure Water,
Inc. v. Safari Water Filtration Sys., Inc., 381 F.3d 1111, 1115
(Fed. Cir. 2004)).
Accordingly, in construing disputed terms, the
Court first looks to the words of the claims.

After the hearing on claim construction and Defendants’
motion for summary judgment, the Court invited the parties to
submit supplemental briefs and additional expert reports on a
limited issue. Defendants argue that, in its supplemental brief
and expert reports, Kelora has included arguments and evidence
that go far beyond the subject matter that the Court gave it leave
to address, and requests that the Court decline to consider this
information. The Court has reviewed Kelora’s supplemental
submissions and finds that they do exceed the scope of the Court’s
prior order. However, the Court OVERRULES Defendants’ objection
as moot, because the Court has considered the arguments and
evidence that exceed the scope and has found that they do not
change the result of this Order.
7
Generally, the Court ascribes the words of a claim their ordinary
2
and customary meaning.
3
“the ordinary and customary meaning of a claim term is the meaning
4
that the term would have to a person of ordinary skill in the art

in question at the time of the invention, i.e., as of the
6
effective filing date of the patent application.”

Throughout their motion, Defendants cite a table that they
include as Exhibit 1 to their motion. This table has
“[a]dditional evidence in support of Defendants’ proposed
construction[s],” which they do not include or discuss in their
brief “[d]ue to space limitations.” Mot. at 37, n.23. Kelora
challenges the consideration of this table, arguing that
Defendants “merely seek to circumvent the already extended page
limit for Defendants’ brief” by including a table with “arguments
not deemed worthy of discussion in Defendants’ Motion.” Opp. at

Accordingly, the Court adopts Defendants’ proposed construction

throughout the claims refers to a “web server.”

Defendants reply that Kelora’s proposed construction

13
The portions of the prosecution history cited by Kelora do
14
not constitute a clear and unmistakeable waiver of subject matter.

Kelora relies on a response sent by the patentee to the

Commissioner for Patents, requesting reconsideration of the

5

3.
“With a server”
Kelora argues in an indirect manner that the phrase “with a
7
server” should be construed to mean “by a server.”
8
that the use of this phrase in the preamble means that all of the
9
steps in claims one and nine require no action by any entity other
Kelora states
United States District Court
For the Northern District of California
10
than a server, specifically, no action by a client computer, and
11
that the “server performs each step.”
12
Defendants respond that this construction is incorrect, because
13
the plain terms of the preamble allow some of the steps to be
14
performed by a client computer as long as it is connected with the
15
server when the step is performed.
16
See Opp. at 47, 48.
As Defendants point out, this Court has already found that
17
the steps in the claims do require some action by a client
18
computer.
19
in step (h) of amended claim one and claim nine, tasks are divided
20
between the client computer and the server, and that “the client
21
computer combines ‘the alternative or alternatives of the first
22
selection criteria plus at least one alternative selected from the
23
revised feature screen,’ which, together, constitute the ‘second

selection criteria.’”

The phrase need not be
“Displaying”
Defendants propose that the word “displaying” should be
8
construed as “showing on the display device of the user’s
9
computer.”
Kelora contends that the word should be construed as

For the Northern District of California
10
“the action of sending a page to a display surface or device for
11

12
Defendants’ proposed construction is more consistent with the

14
from step (c) of claim one, which did not change during
15
re-examination, only by the addition of “wherein data is output to
16
a client computer via said computer network.”
17
this clause means that “displaying” must include the concept of
18
outputting.
19
this already, the additional phrase in claim nine would be
20
superfluous, and step (c) in each claim would have the same

The hypothetical person of ordinary skill in the

The parties agree that “a low level of skill in the art” is
the appropriate standard to use.
While Defendants define this as
“a person with a moderate level of computer science experience
acquired through either formal or informal training,” Mot. at 29,
n.18, Kelora defines it as someone with “2-3 years of experience
or education with computer programming and familiarity with
standards that had been established at the time,” Opp. at 20.
The
difference between these two definitions, if any, is not material
to the resolution of this motion.
Thus, the Court adopts Kelora’s
proposed definition for the purposes of this order.
In its supplemental opposition, Kelora refers to anecdotal
evidence from one of its experts about her first-hand experience
reviewing solutions generated by computer science and engineering
students in response to an assignment to adapt a computer
application with search capability to a networked application.
Kelora argues that, because none of these students adapted the
application to the Web or to use resubmission, such steps were not
22
1
obvious to a person of ordinary skill in the art.
2
expert also refers to the fact that the inventors themselves were
3
unfamiliar with web servers until the second quarter of 1994 and
4
could not have adapted the invention to the Web before that time.
