On May 20, 2014, the Court entered judgment in favor of
13
Defendants HP, Apple, Aruba, Meru, and Ruckus and against
14
Plaintiff Linex.
Docket No. 334.
On June 10, 2014, Aruba, Meru,
15
and Ruckus (collectively, the access point or AP manufacturers)
16
filed a motion seeking an award under 35 U.S.C. § 285 of all of
17
their attorneys’ fees.
Docket No. 345.
HP and Apple filed a
18
similar motion, but sought only attorneys’ fees associated with
19
the asserted claims that the Court found to be valid but not
20
infringed.
Docket No. 346.
Linex opposes both motions and argues
21
in the alternative that the issue of attorneys’ fees should be
22
deferred until the Federal Circuit decides the appeal of the
23
Court’s order.
On July 31, 2014, the Court held a hearing.
Based
24
on the papers and arguments of counsel, the Court GRANTS HP and

BACKGROUND
1
2
In June 2007, Linex filed suit in the Eastern District of
3
Texas, asserting infringement of U.S. Patent No. 6,757,322 (the
4
‘322 patent) against fifteen entities that were not sued here.
5
Linex Techs., Inc. v. Belkin Int’l, Case No. 2:07-cv-00222 JDL
6
(E.D. Tex. June 1, 2007) (the Texas case).
In the Texas case,
7
Linex based its infringement claims on the same 802.11n standard
8
9
invoked here.1
The Texas court issued a claim construction order,
United States District Court
For the Northern District of California
10
construing “spread spectrum signals” as “signals processed with
11
one or more codes that distributes each signal across the
12
available bandwidth.”
13
thereafter, Linex settled its claims with each of the defendants
14
Docket No. 235-16 at 22.
Shortly
for lump sum payments.
15
After the Texas ruling, Linex went back to the United States
16
Patent and Trademark Office (USPTO) to seek reissues of some of
17
18
the continuation patents of the ‘322 patent.
The USPTO can
19
reissue a patent in accordance with an amended application when a
20
patent was erroneously deemed wholly or partly inoperative or
21
invalid, or because a patentee claimed more or less than he had a
22
right to claim in the patent.
23

No new subject

In May 2011, Linex filed a petition at the International
United States District Court
For the Northern District of California
10
Trade Commission (ITC) requesting relief for Defendants’
11
infringement of the ‘322 and ‘219 patents (the ITC Investigation).
12
The ITC can issue an exclusion order halting imports and exports
13
of an infringing product, but cannot award compensatory damages.
14
At around the same time, Linex filed this patent infringement case
15
against Defendants in Delaware, seeking compensatory damages.
The
16
parties agreed to stay the litigation pending resolution of the
17

ITC Investigation.
During the ITC Investigation, the staff attorney issued an

opined that he did “not expect the evidence to show infringement

The staff attorney also determined that there was no domestic
14
industry.

Two business days after the staff attorney’s opinion
15
was published, Linex voluntarily dismissed the ITC action.

stay.

The case was eventually transferred to this

district.

The staff attorney’s position may or may not be adopted by

determination would then be reviewed by the ITC Commission. ITC
decisions are not necessarily binding on the district court.

(c) “combining” terms, and (d) “separating” terms.

–- claims 121 and 131-132 of the ‘219 patent and claims 101-102 of
13

As for the remaining asserted claims not

19
“codes” and “signals” -– claims 97 and 107-108 of the ‘219 patent
20
and claims 97-98 of the ‘812 patent -– the Court found that these
21
claims lacked the spread spectrum limitation distinguishing them
22
from the prior art, and so these claims were invalid.

The Court therefore entered judgment in favor of Defendants on all

asserted claims.

Under 35 U.S.C. § 285, the court “in exceptional cases may

award reasonable attorney fees to the prevailing party.”
In

10
several cases leading up to this year, the Federal Circuit
11
admonished that a district court should not award fees unless it

finds litigation-related misconduct that would independently be

sanctionable, or litigation that was both “brought in subjective
14

This year, however, the United States Supreme Court reviewed
two fee claims and altered the standard for the determination

There is “no precise rule or formula” for this

As a preliminary matter, Linex’s request that the Court defer
15
consideration of the fees issue is without merit.

If Linex did not

In this case, Linex argued that the HT-
LTF, a preordained training field sent before the data signal, was
24
the “data” required by the Court’s construction to create a spread
25

spectrum signal.
Linex’s argument was contradicted by its own
27
infringement expert, who characterized the HT-LTF as “test and
28
control data” more analogous to a code, rather than “message
10
1
data.”
MSJ Order at 33.
Although Linex hypothesized that even
2
test and control data could be “data” under the patents-in-suit,
3
the Court rejected this theory because the specification makes
4
clear that “data” is what is intended to be communicated to the
5
recipient.
6
Id.
Further, even if the Texas court did not
emphasize that “data” is the content or message and is distinct

from a “code,” it did not need to do so because those are the
