CLAIM CONSTRUCTION ORDER
(Re: Docket Nos. 67, 25)
In this patent infringement suit, 1 Plaintiffs Sealant Systems International, Inc. (“SSI”) and
17
18
Accessories Marketing, Inc. (“AMI”) allege that Defendants TEK Global S.R.L. and TEK
19
Corporation (collectively “TEK”) infringe U.S. Patent No. 6,789,581 (the “‘581 Patent”). TEK
20
alleges that SSI infringes U.S. Patent No. 7,789,110 (the “’110 Patent). The parties seek
21
construction of ten terms and phrases for each of the patents. After consideration of the claims,
22
specification, prosecution history, and other relevant evidence, and after hearing the arguments of
23
the parties, the court construes the disputed language of the asserted patents as set forth below.

TEK filed Case No. 11-1649 against SSI alleging infringement of the ‘110 Patent in the Southern
District of New York. SSI filed Case No. 11-774 against TEK seeking a declaratory judgment that
SSI did not infringe the ‘110 Patent in this district. After SSI’s sister company, AMI, purchased the
‘581 Patent from an unrelated third party, AMI’s claim for infringement was added in the first
amended complaint. SSI then filed a second amended complaint adding TEK as a defendant with
respect to the claim of infringement. TEK’s infringement case was transferred to this district and
consolidated with Case No. 11-774.
All parties have consented to magistrate judge jurisdiction pursuant to 28 U.S.C. §636(c).

BACKGROUND
The inventions claimed in both the ‘581 and ‘110 Patents involve a self-contained tire
3
repair kit. Both are aimed at allowing an ordinary motorist to repair and inflate a flat tire while the
4
tire remains on the wheel of the vehicle. 2 The kits allow the motorist to avoid the danger and hassle
5
of replacing a flat tire with a spare alongside a busy highway or a desolate road and provide for
6
more space in the trunk of a vehicle than would be required ordinarily to store a spare tire.
7
The ‘581 Patent was filed on October 31, 2002 and assigned to Interdynamics, Inc.
8
(“Interdynamics”). On April 29, 2011, Interdynamics sold the ‘581 Patent to AMI. The claimed
9
invention has never been sold in the United States.
United States District Court

10
The ‘110 Patent was filed on February 8, 2005 and cites to the ‘581 Patent as prior art. It
11
was assigned to TEK. During the prosecution, original dependent claim 10 was amended to
12
incorporate features of the claim on which it depended and thereafter was allowed. 3 Claim 10 is
13
written in means-plus-function format. In addition, new claims were added parallel to that amended
14
claim and other claims dependent on it, but the means-plus-function terms of the original claims
15
were written in structural terms to avoid the means-plus-function language and were reported as
16
such to the examiner. Those claims also were allowed. 4

LEGAL STANDARDS
Seven years after the Federal Circuit’s seminal Phillips decision, 5 the cannons of claim

construction are now well-known even if not perfectly understood by parties and courts alike. “To
20
construe a claim term, the trial court must determine the meaning of any disputed words from the
21
perspective of one of ordinary skill in the pertinent art at the time of filing.” 6 This requires a careful
22
review of the intrinsic record, comprised of the claim terms, written description, and prosecution

history of the patent. 7 While claim terms “are generally given their ordinary and customary
2
meaning,” the claims themselves and the context in which the terms appear “provide substantial
3
guidance as to the meaning of particular claim terms.” Indeed, a patent’s specification “is always
4
highly relevant to the claim construction analysis.” 8 Claims “must be read in view of the
5
specification, of which they are part.” 9 Although the patent’s prosecution history “lacks the clarity
6
of the specification and thus is less useful for claim construction purposes,” it “can often inform the
7
meaning of the claim language by demonstrating how the inventor understood the invention and
8
whether the inventor limited the invention in the course of prosecution, making the claim scope
9
narrower than it would otherwise be.” 10 The court also has the discretion to consider extrinsic

evidence, including dictionaries, scientific treatises, and testimony from experts and inventors.
11
Such evidence, however, is “less significant than the intrinsic record in determining the legally
12
operative meaning of claim language.” 11

The court notes that it may adjust its construction of the claims at issue if later-introduced

Case No.: C 11-774 PSG
CLAIM CONSTRUCTION ORDER
1
SSI urges that the above claim be given its plain and ordinary meaning. The specification
2
teaches that when the compressor is activated and a container of sealant is in place, compressed air
3
is forced into the container. This pushes tire sealant out of the container and into the receptacle and
4
then into the air flow path air and into the tire. 13 Based on this description, SSI argues that an “air
5
flow path” describes a course or route for compressed air, not limited to any particular hardware or
6
pathway, and which is consistent with its use in the claims. 14 SSI disputes that the patent discloses
7
simultaneous or distinct streams of compressed air that force sealant out of the container and also
8
“continuously” or “directly” direct air into the tire. As an alternative to plain meaning, SSI
9
proposes a construction that describes the route as including “at least one conduit or hose for
United States District Court
For the Northern District of California
10
directing the compressed air.”
11
TEK contends that the embodiments and prosecution history support an interpretation of the
12
claim language that is based on the mixing of air with tire sealant described in the specification. In
13
the Notice of Allowability, the examiner distinguished the ‘581 Patent from prior art based on the
14
air/sealant mixture that results from air being forced into the container of sealant and sealant being
15
pushed out and into the air flow path to the tire. 15 Because the applicant did not challenge the
16
examiner’s statements, TEK argues that there was acquiescence to such a construction. 16 TEK
17
further argues that the air/sealant mixture relied on by the examiner is based on a continuous or
18
direct air flow path from the compressor through a receptacle to a tire. As an example, TEK points
19
to the embodiment of Figure 13 which shows that when the compressor is activated, air flows from
20
the compressor, into and out of the receptacle, to the tire. Tire sealant escapes from the pressurized

2

3
The court agrees with TEK that the claim term requires construction because the language
4
alone does not convey what a person of skill in the art would understand from the intrinsic record
5
as a whole. 18 The claim language, written description, embodiments, and examiner’s statements in
6
the Notice of Allowability all contemplate an air flow path into which air and tire sealant are being
7
mixed. The claims themselves refer to air from the air compressor that “pushes tire sealant out of
8
the container, into said receptacle, into said air flow path,” an exhaust in the receptacle that
9
“receives air and tire sealant from the container and directs the air and tire sealant into said air flow

For the Northern District of California
10
path,” and “tire sealant [that] leaves the container and is entrained into said air flow path.” 19 The
11
specification further explains how one skilled in the art might understand the device: “[w]hen a
12
container of tire sealant is received in the receptacle, the intake directs air from the air flow path
13
substantially into the container, and the exhaust receives air and tire sealant from the container and
14
directs the air and tire sealant into the air flow path.” 20 The examiner’s statement in the Notice of
15
Allowability moreover suggests that this understanding of the invention, predicated on the mixing
16
of air and sealant, is essential to the design’s patentability.
17
The record does not address, however, where the air path lies and whether that path must be
18
continuous or “direct” from the compressor to the tire, as TEK contends. Although air and tire
19
sealant are being mixed along or entrained into a common path (“an air flow path”), nothing in the

1
claim language or specification precludes additional hoses or pathways through which air also
2
might travel. In fact, the specification suggests some dichotomy between the container with sealant,
3
when received in the receptacle, and the air flow path. 21 One of ordinary skill in the art would
4
understand that the air flow path is a route for the compressed air to take, which may include or
5
encompass air being diverted through the container, and which does include air that is being mixed
6
with tire sealant. The court thus finds that elements of both parties’ proposed constructions are
7
appropriate to describe the plain meaning of the term. “An air flow path from said compressor
8
adapted to be connected to a tire” will be construed as “a route from a compressor to a tire into
9

SSI contends that the above claim term should be given its plain and ordinary meaning
14
15
because the meaning is readily apparent even to lay people and involves little more than the
16
application of commonly understood words. The plain meaning of the claim term also is supported
17
by the specification. 22 TEK responds that the plain and ordinary meaning fails to capture the full
18
meaning imputed by the claim language and specification.
Claim 1 describes “a receptacle formed in said housing in communication with said air flow
19
20
path adapted to sealingly receive a container of tire sealant” and explains that compressed air
21
“pushes tire sealant out of the container, into said receptacle, into said air flow path, and into the

volumetric shape capable of receiving and exhausting air and sealant that is taught. It disputes that
3
“receptacle” alone sufficiently denotes a volumetric shape. TEK further contrasts “receptacle” as

used in the claim language from “port,” which the specification describes may be integral with the
5
housing or may be a separate element. 24
6
The court is not persuaded that the claim term requires further construction. The word
7
“receptacle” connotes depth to the extent that it is able to receive a container of tire sealant and
8
provide a pass-through for sealant leaving the container and entering into the air flow path. The
9
court accepts SSI’s contention that a person skilled in the art would understand “receptacle” as

10
something that receives or contains something. The court does not find that substituting
11
“enclosure” helps to clarify the claim meaning. Nor does the claim language or specification
12
require that that the receptacle be integral to the housing. The receptacle’s function, according to
13
the claim language and specification, is to connect to the flow of compressed air and to sealingly
14
receive a container of sealant. The patent uses the word “integral” elsewhere both to specify the
15
placement of a component (“a button or pressure relief valve integral with receptacle 14 or port
16
40…”) 25 or to specify an alternative structure (“portions of or all of the port may be made integral
17
with the housing”). 26 These uses suggest that the absence of “integral” in the description of the
18
receptacle is not happenstance. Without more, the court will not impose “integral” as a limitation. 27

“exhaust receives air and tire sealant

that these claim terms have a plain and ordinary meaning that is supported by the claim language
and specification. TEK’s proposed constructions 28 rely on the same reasoning as TEK urged with
respect to claim No. 1. For example, TEK argues that for claim term No. 3 to have literal meaning
wherein sealant is pushed out of the container into the air flow path, and for there to be air/sealant
mixing as the examiner stated, there must be a continuous flow of air from the compressor to the
tire through the receptacle. As explained earlier, the mixing of air and sealant in the air flow path
does not necessarily support TEK’s limitation of a continuous or direct path. The terms therefore
will be given their plain and ordinary meaning, taking into account the adopted construction for “an
air flow path.”

delivers them into the compressed air stream flowing directly from the air compressor to the tire.”

basis for it. Although claim 10 is dependent on claim 2, which itself is dependent on claim 1,
2
claims 1 or 2 make no reference to the “opening” indicated by claim 10. The lack of antecedent
3
basis, however, does not render either claim term indefinite, because a person skilled in the art
4
would understand from the context of the claims that the containers described in the specification
5
have an opening that is sealingly received in the receptacle. 29 That opening is discussed in several
6
places in the specification and described as “preferably provided with a single opening.” 30
7
Turning to the construction, SSI contends that the claim terms relating to intake and exhaust
8
should be given their plain and ordinary meaning. In the alternative, SSI would interpret the
9
phrases to mean that “the intake and exhaust openings point in (or, alternatively, face) a different
United States District Court
For the Northern District of California
10
direction from the opening of a container of tire sealant.” TEK proposes what it asserts is
11
essentially the plain meaning – the intake and exhaust openings are on opposite sides of the
12
opening of the container. TEK points to Figure 5 to support that construction. Figure 5 and the
13
accompanying description show an intake nozzle and internal bore terminating in intake hole 46,
14
and an exhaust nozzle and internal bore terminating in exhaust hole 47. 31 The specification teaches
15
that intake hole 46 lies within the bottle when a container of sealant is secured to the receptacle,
16
while exhaust hole 47 lies outside the opening of the bottle. Hence, the openings are on opposite
17
sides of the container of sealant.
18
SSI argues that this construction is contradicted by the language of claim 33, depending
19
from claim 31, which refers to the intake and exhaust nozzles (that point in a different direction
20
from the container opening as shown in Figures 4 and 5) and not to “intake hole 46” or “exhaust
21
hole 47.” Under Section 112, a claim in dependent form must be construed to incorporate the

limitations of the reference claim. 32 By SSI’s reasoning, the intake and exhaust terms in claims 10,
2
13, 33 and 36 – which refer merely to “said intake” and “said exhaust” – would be bound by the
3
reference in dependent claim 33 to the intake and exhaust nozzles described in claim 31. Yet
4
claims 10, 13, and 36 are also dependent claims, none of which refer back to exhaust nozzle or
5
intake nozzle limitations. Claims 10 and 13 depend from claim 2, which describes generally “an
6
intake” and “an exhaust” in the context of the receptacle; claim 36 depends from claim 28, which
7
describes the same in the context of the port. 33

The court agrees with TEK that a person skilled in the art, reviewing the terms at issue and
in the context of the entire specification, would understand “opposite substantially the same

11
This interpretation is consistent with Figures 4 and 5 as well as the specification. Similarly, for the
12
opening to “substantially oppose[]” the intake and exhaust when the container is received in the
13
receptacle (claim 13) or the bottle is secured to the port (claim 36), the exhaust and intake openings
14
located in the receptacle must serve as the point of reference. The court will adopt TEK’s proposed

TEK contends that a port shares many of the same characteristics as a receptacle except that
2
it may or may not be formed in the housing. It points to the following examples: (1) “[a] receptacle
3
and/or port is formed in the housing in communication with the air flow path” 34; (2) “[t]he port

may be a separate attachment that can be secured to a container of tire sealant, or it may be integral

port 140 is substantially similar to port 40 described above. However, port 140 is not necessarily

adequate, because as with receptacle, port as used in the specification is a structure that has a

13
The court agrees with TEK. Although the purpose of the specification is to teach and not to
14
impose a further limitation on the relevant claim, “port” alone does not connote the extent of the
15
structure described in the patent. According to the specification, “port” may be integral to the
16
housing or may be a separate structure. 39 Indeed, the specification describes embodiments that are
17
not integral to the housing. 40 The port as claimed comprises an intake and an exhaust for

United States District Court
For the Northern District of California
10
SSI contends that the above claim term should be construed to avoid any misconception
that “receptacle,” “port,” and “reservoir” refer to the same structure. SSI proposes that reservoir be
construed as “a cavity where sealant collects separate from the container.”
11
TEK responds that as used in Claim 42, which reads on the embodiment of Figure 12,
12
“reservoir” has the characteristics and functionality of a receptacle to which a container of sealant
13
has been mounted if the device is used for repair, or onto which a cap is screwed if the device is
14
used for inflating a tire. The reservoir must be in connection with the air flow path, allowing
15
compressed air to pass through the reservoir if there is no sealant in the reservoir, or to push sealant
16
out of the reservoir, into the air flow path if there is sealant in the reservoir. 43 TEK therefore
17
concludes that reservoir should be construed the same as receptacle.
18
Even though “reservoir” and “receptacle” serve similar functions in different embodiments,
19
the specification teaches that they are different structures. To construe both in the same way
20
ignores this difference and might confuse a jury as to the role of each structure. Both receptacle and
21
port are adapted to receive a container or bottle of tire sealant, whereas as used in claim 42, the
22
reservoir simply is “adapted to receive tire sealant.” The specification teaches that after removing
23
the cap, sealant is poured directly into the reservoir, into which air is directed from the compressor
24
and out of which is exhausted both air and tire sealant. As with “receptacle,” the specification may
25
allow for but does not require that the reservoir be formed integral to the housing.

Claim 42
SSI contends that the above claim term should be given its plain and ordinary meaning.

Consistent with its earlier arguments, TEK contends that there is a direct and continuous stream of
11
compressed air from the compressor to the tire, as evidenced by air and sealant mixing as the
12
sealant is pushed out of the reservoir and into the tire.
13
As with claim term Nos. 3 and 4, the claim language, specification, and file history do not
14
support a construction that the compressed air flows “directly” from the air compressor to the tire.
15
A person of skill in the art would understand the claim in context to mean simply what it says –
16
that compressed air moves through the reservoir and pushes sealant out along with the air. As

“tire sealant leaves the container and is

Tire sealant leaves the container and is drawn

Claims 43 and 44
SSI contends that the above claim term should be given its plain and ordinary meaning.
25
TEK responds that the claim term should be construed because the words “entrained into said air
26
flow path” are given special meaning by the written description. As used in Claims 43 and 44,
27
which read on the embodiment of Figure 13, sealant leaves an already pressurized container when
28
the switch on the container is activated; sealant is not forced out by a stream of compressed air, as

3
When switch 319 is also activated, tire sealant escapes container 316 and is emitted into the air

flow path and entrained with the air heading towards the tire.” 44 TEK thus proposes a construction
5
that describes tire sealant leaving the container as being “swept into the compressed air stream
6
flowing directly from the air compressor to the tire.”
7
The court agrees that there is a distinction between tire sealant leaving a pressurized
container upon activation of a switch or being forced out by the entry of compressed air. It is
9
sufficient, however, that the claim term uses “leaves” for this purpose, and which TEK does not

12
not in common usage and the specification teaches that the air leaving the pressurized container is

effectively drawn into and mixed with the flow of air, the court will adopt the following

construction: [t]ire sealant leaves the container and is drawn into the air flow path. As the court

TEK contends that the function, as stated in the claim, is to connect the container to the

proposed construction additionally reflects the actual function performed by the claim element, i.e.,

the function of “connecting means” is to provide air from the compressor to the container and to

The court agrees with TEK that the claim term need not include the limitation that the

function is to provide air from the compressor to the container. Although providing air may indeed
21
be the practical effect or result, nothing in the claim language or specification requires this

The corresponding structure to “connecting means” is identified in the claim by reference to
elements 4 and 5 in the figures. These are described in the specification as follows:
Kit 1 substantially comprises an electric compressor assembly 2; a container 3 of sealing
liquid; a first hose 4 connecting container 3 to compressor assembly 2, and a second hose 5
connecting container 3 to a valve (not shown) of the tyre. 47

The specification goes on to describe a particular fitting for first hose 4:
First fitting 50 is connected to hose 5, which, when not in use, may be wound about the
casing …; and second fitting 53 is connected to compressor 2 by hose 4. Conveniently,
hose 4 is longer than required for connection to fitting 53, and is fitted on its free end with
a fast-fit, e.g. lever-operated, coupling 58. Hose 4 is therefore normally connected to
second fitting 53, but can be detached easily and connected directly to the article, e.g. a
tyre, ball, dinghy, etc., if this simply needs inflating and not repair. 48

10
The parties disagree whether the fast-fit coupling is a necessary component of the corresponding
structure.
11
TEK contends that the initial description in the specification, based on the reference to
12
elements 4 and 5, adequately defines the structure of the connecting means. TEK argues that SSI’s
13
proposed limitation to include the fast-fit coupling is too narrow because one of ordinary skill in
14
the art would understand that multiple types of connections can be used to connect a hose to a
15
compressor. The plain language of the specification demonstrates this by referring to the “lever-
16
operated,” fast-fit coupling as an example only (using “e.g.” and not “i.e.”) for “convenience” and
17
not as a necessary part of the structure. 49 TEK further points to the embodiment depicted in Figure
18
7 in which TEK argues that there is no need for a fast-fit coupling because the hose connecting the
19
container to the compressor assembly does not get removed, even if the device is to be used solely
20
for inflation and not for repair.
21
SSI responds that the corresponding structure includes not only first hose 4 and second hose
22
5, but also the specific fittings disclosed in the specification. SSI argues that because the
23
specification discloses the specific fittings, that disclosure must be considered in determining the

corresponding structure. 50 That similar types of connectors can be used goes to the issue of

“equivalents” to the claimed structure, not to its inclusion in the first instance. SSI further points
3
out that TEK previously included “associated fittings” in its proposed claim construction.
4
SSI is correct that “under § 112 every structure disclosed in the specification and its
5
equivalents should be considered.” 51 But a structure disclosed in the specification is a
6
“corresponding” structure “only if the specification or prosecution history clearly links or
7
associates that structure to the function recited in the claim.” 52 Here, the defined function of
8
connecting means is connecting the container to the compressor assembly and to an inflatable
9
article for repair or inflation. Because the connection to the inflatable article includes both repair

For the Northern District of California
10
and inflation, the fast-fit, e.g., lever-operated coupling described in the specification is clearly
11
linked to the function of connecting the hose to the inflatable article. As TEK points out, however,
12
the fast-fit coupling is identified in the best mode section of the specification, and “lever-operated”
13
is provided only as an example. The specification corresponding to Figure 7 describes a second
14
embodiment in which there remains a connecting means between the container, compressor
15
assembly, and inflatable article, but no particular fitting type is specified. Yet the unspecified
16
fitting is clearly linked to the connecting means function. 53 The court therefore will construe
17
“connecting means” to have encompass two corresponding structures: (1) a first hose connecting
18
the container to the compressor assembly and fitted in its free end (i.e., opposite the end connected
19
to the compressor) with a fast-fit, e.g., lever operated, coupling, and a second hose connecting the
20
container to a valve of the inflatable article; and (2) a first hose connecting the dispenser unit to the

compressor assembly with a fitting, and a second hose connecting the container assembly to the

inflatable article.

TEK contends that the claim term should be given its plain meaning as would be
understood not only by one of ordinary skill in the art but also by a lay person. The seat for a
container of liquid is shown in Figures 1, 2 and 4 and is described consistently in the specification
as being contained in the outer casing. For example, the Disclosure of Invention states: “[T]he kit
… being characterized by comprising an outer casing housing said compressor assembly and
defining a seat for the container of sealing liquid….” 54 In addition, the best mode section describes
the seat within the housing as follows:
12
Casing 6 is substantially parallelpiped-shaped and, at one longitudinal end, defines a seat 7
for housing container 3 upside down. More specifically, seat 7 is bounded laterally by a
substantially semicylindrical end wall 10 of casing 6, and at the bottom by a circular base
14 projecting from the end wall 10. 55

SSI responds that the plain meaning fails to capture a limitation that is made clear by the

intrinsic record – that when the container is housed in the seat, it is maintained “functionally

(2).” 56 In addition, in the Background of the Art, the patentee distinguishes the proposed kit from
other prior art tire repair kits by noting that they were not functionally connected to the compressor
when housed in the casing and required connection of the separate parts before use. 57

proposed construction, adding “easily” to indicate that the container is “capable of being easily
removed from its seat, i.e., without having to disassemble any part of the tire repair kit to remove it
from its seat,” is necessary to enforce a distinction that the patentee made over prior art. The
claimed invention explains that the dispenser unit is detachably connected to the container and that
the container includes an integral valve to ensure the container is closed fluid tight when detached
from the kit. 58 SSI argues that TEK cannot now construe the claims in a manner that eliminates this
distinction. The parties also dispute whether a second embodiment in the patent contradicts SSI’s
proposed limitation by teaching removal of the dispenser unit from the kit along with the container,
rather than removal of the container from the seat without disassembly of any part of the kit. 59
The court finds that “said container being housed removably in said seat” requires no
further construction. The prior art distinction based on removability is not lost in the plain
meaning. Nothing in the specification or prosecution history uses the word “easily,” although a
person of skill in the art might understand “removable” to indicate that the container may be
removed requiring some effort less than disassembly. The section of the specification that provides

TERM
“a three-way valve” 68
TEK contends that the above claim term should be given its plain meaning which is “the
11
12
input of a three-way valve,” a three-way valve being a valve with one input and two outputs. SSI
13
proposes construction of the entire phrase not limited to the input but including the output as well.
14
SSI’s proposed construction also would include language linking the three-way valve to the
15
enabling positions of the selector described in the specification. 69 Alternatively, SSI accepts TEK’s
16
description of a valve with one input and two outputs.
17
It is appropriate to construe the phrase “a three-way valve” rather than solely that pertaining
18
to the valve input, which risks leaving a jury with an incomplete understanding of the structure. As
19
shown diagrammatically in Figure 7 as element 81 and described in the written description, the
20
three-way valve has an input connected to the compressor assembly, an output to the conduit

25
The parties dispute whether the court is to construe “a three-way valve input,” as initially

agrees with SSI that construction of “a three-way valve” is appropriate, as explained above.

Claims 2-5
11
The parties disagree whether “a valve device” means one or more valves or only a single
12
13
valve. TEK argues that in the field of patents, the indefinite article “a” carries a meaning of “one or
14
more” in open-ended claims. 71 Because the claim for “a valve device” is not specific as to the
15
number of elements and does not indicate a singular limitation, TEK contends that it should be
16
given its plain meaning, or alternatively should be construed to mean “one or more” valve devices.
17
SSI responds that the article “a” should be construed to mean a single valve based on the
18
19
intrinsic record, which fails to disclose any reference to or embodiment using more than a single
20
valve. 72 For example, the claim language refers to a valve device having “an” inlet connectable to
21
said compressed-air feed line and “an” outlet for the sealing liquid. The claim also identifies the
22
valve device by numeral 18, which the patent exclusively and extensively describes as a single

The Federal Circuit recently addressed the construction of claim language using the article

“a.” In 01 Communique Laboratory, Inc. v. LogMeIn, Inc., the court reiterated the circuit’s “well-
5
established precedent” that “‘[a]s a general rule, the words “a” or “an” in a patent claim carry the
6
meaning of “one or more.”’” 74 The court further explained that exceptions to the general rule are

few and do not extend to the subsequent use of definite articles “the” or “said” when referring back
to the claim term. 75 Unless the claim language, the specification, or the prosecution history

10
“necessitate a departure from the rule,” the term shall retain its non-singular meaning. 76 In
11
LogMeIn, Inc., the court found the use of singular referents such as “its location on the Internet
12
being defined by a static IP address” as well as figures in the specification showing the term in
13
14
question – “the location facility” – to be represented by a single box to be insufficient to overcome
the presumption of plural meaning. 77

Here, the patentee similarly has not shown any clear intent to limit the claim to a single

United States District Court
For the Northern District of California
10
The parties agree that the claim term is a means-plus-function term subject to 35 U.S.C.
11
§112 (6). They agree that the elastic means must keep a control member closed in the absence of
12
pressure. The parties further agree that the corresponding structure is a spring and its equivalents.
13
The parties disagree, however, whether for the “elastic means” to function as intended, it must
14
open in response to air pressure and return to a closed position when the air pressure is removed.
15
TEK contends that the function of “elastic means” is set forth in Claims 4 and 14 and does
16
not need modification. Claims 4 and 14 are identical except for reference to their base claims.
17
Claim 4 states:
4. A kit as claimed in claim 3, characterized in that said valve device (18) comprises elastic
means (31) for keeping said control member (30) stably in said closed position in the
absence of pressure to said inlet (27c). 79
18
19
20
TEK argues that is consistent with the discussion of valve 18 in the written description, which
21
describes valve 18 in pertinent part as follows:
22
Device 18 therefore acts as a two-way, two-position, pneumatic valve. In the closed
position (Fig. 5), the container is sealed; with pressure along the feed line defined by hose
4, device 18 opens automatically to allow compressed air into container 3, and
simultaneous outflow of sealing liquid. 80

Using a two-way valve device, 18 closed stably in the absence of pressure along the feed
line 4, sealing liquid leakage is prevented, even in abnormal conditions, such as
overpressure in container 3 caused by high temperature inside the boot of a car parked in
the sun. 81
4
SSI’s proposed construction introduces a limitation not found in the specification, that the elastic
5
means must be able to return the control member to its original position upon removal of the air
6
pressure. According to TEK, the condition whereby the elastic means keeps the control member
2
7
closed in the absence of air pressure is met at least from the time the tire repair kit is assembled
8
9
until the time as it is used to repair a tire. The control member may or may not be forced to return

to its original position, depending on the overall design of valve 18, but the claims nevertheless do
11
not require it one way or the other.
12
13
14
15
SSI responds that TEK’s construction ignores the plain meaning of the term and its own
summary of the invention, in which TEK explains that “prior to the introduction of compressed air
into valve 18, interior element 30 is held in a closed position by the elastic means, spring 31,” but
when compressed air is fed into the valve, “spring 31 compresses, and air flows into container 3.” 82
16
17
Similarly, the specification describes the action by which pressure along the feed line causes device
18
18 to “open[] automatically to allow compressed air into [the] container, and simultaneous outflow
19
of sealing liquid.” SSI thus contends that the specification supports a definition of the “elastic
20
means” that keeps the control member stably closed in the absence of air pressure, “open in the
21
response to air pressure, and able to return to its original position upon removal of the air
22
pressure.”
23
The court agrees with SSI but only in part. That the corresponding function of “elastic
24
25
means” is to respond both to the absence of air pressure (by maintaining a closed position) and to

the presence of air pressure (by opening) is inherent in the meaning of the claim term and is
2
supported by the written description. The relevant inquiry is whether “elastic” is itself a functional
3
term or merely describes a characteristic the structure is capable of performing. 83 Like the term
4
“release” in Baran v. Medical Device Technologies, Inc., “elastic” is not an “idle description.” 84
5
“Elastic” implies a function capable of changing or deforming in response to pressure. TEK’s
6
proposed construction ignores this meaning of “elastic;” for example, a non-elastic means also
7
8
9
could “keep a control member stably in a closed position in the absence of air pressure.” The
elastic means, however, functions to keep the control member closed in the absence of air pressure
United States District Court
For the Northern District of California
10
and, by definition, to open in response to air pressure. 85 The written description supports this
11
construction wherein the function of the elastic means is to keep the control member in a closed
12
position until compressed air is fed to the valve, and to open in response to that air. TEK is correct,
13
14
however, that nothing in the claim language or even the intrinsic record requires the elastic means
also be “able to return to its original position upon removal of the air pressure.” This additional

clause suggests a function that the structure may indeed be capable of performing in a working

absence of “means” in a claim creates a countervailing presumption that §112(6) does not apply. 87
7
The presumption that §112(6) does not apply can be rebutted by evidence intrinsic to the patent or
8
by relevant extrinsic evidence. 88 There are two ways in which the intrinsic evidence can serve to
9
rebut this presumption: either the claim term “fails to ‘recite sufficiently definite structure’ or else
United States District Court
For the Northern District of California
10
recites a ‘function without reciting sufficient structure for performing that function.’” 89 In
11
12
13
determining whether a claim term has sufficient structure to maintain the presumption, the court
examines whether the term has an understood meaning in the art. 90
TEK contends that the claim term sufficiently identifies “conduits” as the structural element
14
15
and further argues that the phrase is readily understood without further construction. TEK finds
16
support in the prosecution history, wherein original dependent claim 10, noted to be allowable if
17
18
amended to incorporate the features on which it depended, was rewritten to avoid means-for
language and the limitations of 35 U.S.C. §112(6). 91

purposes identical to the functional language of “container connecting means” used in claim 1,
2
except “conduits” is substituted for “connecting means for.” 92 SSI argues that TEK’s claim term
3
cannot be construed to cover every way or means to perform the function of connecting the
4
container to the compressor assembly and to an inflatable article for repair or inflation – as might
5
be suggested by the broader term “conduit” – in light of the limited disclosure in the specification.
6
SSI also argues that TEK’s reliance on the prosecution history is misplaced. While the inventor

8

United States District Court
For the Northern District of California
10
sought to avoid the limitations of 35 U.S.C. §112(6), he represented to the examiner that they were
“patentable for the same reasons” as the allowed claims. SSI contends that TEK should not be
permitted now to change the claim scope.
11
With respect to the form of the claim terms at issue, the court finds that 35 U.S.C. §112(6)
12
does not apply. Both claims lack “means-for” language and presumptively do not fall within
13
paragraph 6 of §112. 93 “Conduit” is a noun that describes a general class of structures sufficient to
14
avoid construction under 35 U.S.C. §112(6). 94 The court finds that “conduit” is not a generic term
15
16
along the lines of “mechanism,” “means,” “element,” or “device,” 95 but recites a structure that
17
would be understood by one skilled in the art and in light of the claim language. The prosecution
18
history further establishes that the language in the original claims was rewritten to avoid means-for
19
language. It is nevertheless appropriate to construe these terms, given the broad range of structures
20
that “conduit” may be understood to incorporate and in light of the prosecution history. The terms

Claims 29 and 30

Dependent claims 29 and 30 refer to claim 26 “wherein said valve device comprises at least

9
“[S]aid valve device,” however, lacks an antecedent basis in claim 26. SSI contends that the lack of
United States District Court
For the Northern District of California
10
antecedent basis renders the term indefinite. SSI offers no alternative construction. TEK responds
11
that the lack of an antecedent basis is not dispositive if despite the absence of explicit antecedent
12
basis, “‘the scope of the claim would be reasonably ascertainable by those skilled in the art.’” 96
13
TEK contends that even though claim 26 does not recite a valve device, one of ordinary
14
skill in the art can readily determine that “valve device” in claims 29 and 30 is identical to that in
15
dependent claims 13 and 14 (referring back to claim 1). The patentee stated that “New claims 28-
16
30 are dependent on claim 26 and parallel original claims 11, 3 and 4 [sic, 11, 13 and 14] written in
17
structural rather than “means for” language.” 97 TEK therefore concludes that the claim term “said
18
valve device” is not indeterminate and corresponding claims 29 and 30 are not indefinite, because a
19
person skilled in the art would apply the same meaning to “said valve device” in claims 29 and 30
20

CLAIM CONSTRUCTION ORDER
1
SSI argues that claims 29 and 30 refer only to a different valve, i.e. a three-way valve, that
2
performs a wholly different function, and not to any element in which “said valve” may be viewed
3
as an inherent component. 99 SSI also argues that the prosecution history is insufficient to clarify the
4
antecedent basis, because the patentee identified claims 3 and 4 as parallel to claims 29 and 30.
5
Claims 3 and 4 depend from claim 2, so that the court would have to re-write claim 26 (or claims
6
29 and 30) to add claim 2, which in relevant part reads: “connecting means comprise … and a
7
valve device (18) fitted in a fluid-tight manner to the opening (17) and having an inlet (27c)
8
connectable to said compressed-air feed line (4), and an outlet (29a) for the sealing liquid.” In
9
addition, claim 2 is written in a means-plus-function format that would further convolute any re-
United States District Court

10
writing of claim 26.
11
Claims 3 and 4, identified in the prosecution history, provide an antecedent basis for “said
12
valve device” by referring back to claim 2. A person skilled in the art, reading the claim language,
13
the specification, and looking to the explanation in the prosecution history that claims 28-30
14
parallel original claims 11, 3 and 4, would understand the basis for “said valve device” as “a valve
15
device (18) fitted in a fluid-tight manner to the opening (17) and having an inlet (27c) connectable
16
to said compressed-air feed line (4), and an outlet (29a) for the sealing liquid.” 100 The term is
17
therefore not indefinite and will be given its plain and ordinary meaning, consistent with the
18
construction of “a valve device” set forth above with respect to claim term No. 6.
