MARCO A. HERNANDEZ, District Judge.
Plaintiff Skedco, Inc. brings this action against Defendant Strategic Operations, Inc., alleging that Defendant infringes Claims 18-20 of United States Patent No. 8,342,652 ("the '852 Patent") which discloses a system for simulating hemorrhages in the training of first responders. The United States, through the Secretary of the Army, owns the '852 Patent. Plaintiff alleges that it is the sole and exclusive licensee of the '852 Patent under an agreement which also gives Plaintiff the right to bring this action in its own name. Sec. Am. Compl. at ¶¶ 10, 11.
On May 16, 2014, the parties submitted a Joint Proposed Claim Construction Chart identifying six disputed terms or phrases in Claim 18 of the '852 Patent. The parties then simultaneously filed opening claim construction memoranda and simultaneous responsive memoranda. Oral argument was held July 25, 2014.
At the conclusion of oral argument, I resolved the disputes as to five of the contested terms or phrases. I took construction of the phrase "controller connected to" under advisement and allowed Defendant to submit a response to a newly cited case by Plaintiff. Having now considered the case and the supplemental briefing, I construe "controller" as "an activation mechanism," and I construe "connected to" as "joined, united, or linked to."
"[T]he construction of a patent, including terms of art within its claim, is exclusively within the province of the court."
To construe a patent claim, courts look to the language of the claims in the patent itself, the description in the patent's specification, and the prosecution history of the patent, all of which constitute a record "on which the public is entitled to rely."
"The actual words of the claim are the controlling focus."
There is a "heavy presumption" that a claim term carries its ordinary and customary meaning, and any party seeking to convince a court that a term has some other meaning "must, at the very least," point to statements in the written description that affect the patent's scope.
"An accused infringer may overcome this `heavy presumption' and narrow a claim term's ordinary meaning, but he cannot do so simply by pointing to the preferred embodiment or other structures or steps disclosed in the specification or prosecution history."
"[C]laims are always construed in light of the specification, of which they are a part."
Still, "[c]laims are not interpreted in a vacuum[.]"
Claims may not "enlarge what is patented beyond what the inventor has described as the invention."
Finally, claims should not be limited to the preferred embodiment.
"[T]he distinction between using the specification to interpret the meaning of a claim and importing limitations from the specification into the claim can be a difficult one to apply in practice."
Prosecution history of a patent with the United States Patent and Trademark Office (USPTO) "limits the interpretation of claims so as to exclude any interpretation that may have been disclaimed or disavowed during prosecution in order to obtain claim allowance."
Consideration of intrinsic evidence will resolve any claim term ambiguity in most circumstances.
In the end, the court's ultimate goal is to construe the disputed terms in a manner consistent with the way the inventor defined them and a person of ordinary skill in the art would understand them.
The short description of the '852 Patent is a "Trauma Training System." Ex. A to Sec. Am. Compl. at 1. It was issued by the USPTO on January 1, 2013.
Plaintiff alleges that Defendant infringes at least Claims 18, 19, and 20 of the '852 Patent. Those claims state:
Ex. A to Sec. Am. Compl. at 29 (Col. 14, lines 3-24).
Defendant argues that the word "controller" should be interpreted as "an activation mechanism for said pump and said valve." Jt. Prop. Claim Constr. Chart at 9. Plaintiff contends that "controller" needs no construction. Id. Alternatively, Plaintiff argues that the word should be construed only as "an activation mechanism." Pl.'s Op. Claim Constr. Brief at 13.
Plaintiff argues that the word "controller" needs no construction because it is self-explanatory and is a well-known term having an ordinary meaning to a person of ordinary skill in the art. Defendant suggests that because the patent claims and specification refer to several "controller" terms, some definition of controller is appropriate. In the claims themselves, the majority of the references are to the single word "controller."
Additional references are found in the specification.
It is clear from the specification that the "fluid flow controller" designated as "120," is distinct from the "controller" designated as "126." In fact, the controller 126 is one part of what comprises the fluid flow controller 120. For example, the specification describes Figure 2A as "an exemplary embodiment of the flow controller
Although the specification indicates that fluid flow controller 120, or flow controller as it is sometimes referred to, is different than the controller 126, Defendant is correct that the claims and the specification contain several uses of the word "controller." Because each of these uses has a distinct meaning, I reject Plaintiff's argument that "controller" is self-explanatory and requires no additional construction. The several uses are confusing and the plain and ordinary meaning of the single word "controller" is not obvious. Thus, I agree with Defendant that the single word "controller" requires construction.
Both parties agree that "controller" is an "activation mechanism." Defendant proposes additional limiting language by construing the term "controller" as "an activation mechanism for said pump and said valve."
Defendant relies on the language in Claims 1 and 18 which refers to "a controller connected to at least one of said pump and said at least one valve," 11:49-50 (Claim 1), and "a controller connected to said pump and at least one valve[.]" 14:10-11 (Claim 18). Defendant argues that the claim language would not provide for the controller being connected to the pump and the valve if it was not meant to control the pump and the valve. But, as Plaintiff points out, the claim, by providing that the controller is connected to the pump and the valve, already discloses that the controller is an activation mechanism for the pump and the valve. Adding "for said pump and said valve" to the definition of controller would be redundant and superfluous. I agree with Plaintiff that importing the adjacent claim language into the interpretation of "controller" is not required to adequately define "controller" and would be error.
Still relying on claim language, Defendant argues that because the patentee referred to a "remote controller" and a "flow controller" in Claims 16 and 17, and only to a "controller" in Claim 18, the "controller" in Claim 18 must mean something different than a "remote controller" and a "flow controller." Defendant further notes that the "remote controller" in Claim 16 controls a pump but not a valve. As a result, Defendant argues, the "controller" in Claim 18 must control both the pump and the valve because if the patentee had intended Claim 18's controller to control only the pump, it would have replicated the language of Claim 16 and directed the controller to the pump alone.
Generally speaking, the doctrine of claim differentiation is "based on the common sense notion that different words or phrases used in separate claims are presumed to indicate that the claims have different meanings and scope."
But, "there is still a presumption that two independent claims have different scope when different words or phrases are used in those claims."
The Federal Circuit "has cautioned," however that "claim differentiation is a guide, not a rigid rule."
In applying the "doctrine of claim differentiation" to two independent claims," two considerations generally govern": "(1) claim differentiation takes on relevance in the context of a claim construction that would render additional, or different, language in another independent claim superfluous; and (2) claim differentiation can not broaden claims beyond their correct scope."
Claims 17 and 18 are independent claims. Thus, the doctrine of claim differentiation is not at its strongest. I agree with Defendant that Claim 16's reference to "remote controller" and Claim 17's reference to "flow controller" indicate that the reference in Claim 18 to only "controller" is to something other than a "flow controller" and a "remote controller." But, as explained above, that is why "controller" requires construction and why its meaning as "an activation mechanism" distinguishes it from other types of controllers. I disagree with Defendant that the claim language requires that the single word "controller" be construed as "activation mechanism for said pump and said valve" in order to distinguish it from "remote controller" and "flow controller" used in Claims 16 and 17.
Defendant is correct that Claim 16 sets forth a claim including a "remote controller adapted to control the operation of said pump[.]" 13:6-7. From there, Defendant argues that because the remote controller in Claim 16 controls a pump but not a valve, the controller of Claim 18 must control both the pump and the valve.
I disagree. First, accepting that the remote controller in Claim 16 is distinct from the controller in Claim 18 does not necessarily mean that they perform distinct functions. That is, that a "remote controller" controls only a pump does not inherently suggest that a "controller" controls something more than a pump. Second, and more importantly, Claim 16 depends from Claim 15, which depends from Claim 13, which depends from Claim 2, which depends from Claim 1. Thus, Claim 16 claims the following device, in relevant part:
(1) a trauma training system comprising a controller connected to at least one of said pump and said at least one valve, (Claim 1);
(2) with at least one wound site detachably in fluid communication with said valve, (Claim 2);
(3) with a manifold connected to said at least one valve which has a plurality of conduits connected to the manifold with each conduit having a connector at its free end, with said connector including a seal, (Claim 13);
(4) where the conduit is sown into a body suit or located between two layers of said body suit, (Claim 15); and
(5) with a remote controller adapted to control the operation of said pump and where in said at least one valve includes a manifold having a plurality of valves, (Claim 16).
The invention claimed in Claim 16 starts with Claim 1 which has the same controller as Claim 18. The patent claims then refine or narrow that controller to be a remote controller which is adapted to control the pump. Thus, based on the claim language alone, Claim 16 is distinguishable from the invention in Claim 18 and there is no need to apply the doctrine of claim differentiation to construe the controller in Claim 18 to expressly control both the pump and the valve. The construction of "controller" in Claim 18 as an "activation mechanism" does not render additional or different language in independent Claim 16 superfluous. Put another way, "controller" in independent Claim 18 does not have to be further limited by the words "for said pump and said valve" in order to distinguish it from the "remote controller" claimed in Claim 16.
Defendant argues that each depiction in the '852 Patent Figures shows the controller/activation mechanism 126 connected to both a pump and a valve. Defendant further argues that each reference in the '852 Patent specification to the controller/activation mechanism 126 indicates it is connected to both a pump and a separate valve. As a result, Defendant contends that the word "controller" must be construed an "activation mechanism for said pump and said valve."
Defendant is correct that in Figures 2A, 2B, and 5, the controller/activation mechanism 126
As to the specification, the first reference to the controller 126 is in a description of Figure 2A and identifies it as "an activation mechanism." 4:40-41. In support of its argument that every reference to the controller/activation mechanism 126 in the specification describes it as connecting to the pump and the valve, Defendant cites to only three specific descriptions. Def's Op. Claim Constr. Brief at 19 (citing 4:39-42 (description of Figure 2A)); Def.'s Resp. Claim Constr. Brief at 12 (citing 4:39-42 (description of Figure 2A); 4:56-49 (description of Figure 2B); 5:46-51 (description of Figure 3)).
I found additional references in the specification to the controller/activation mechanism 126, or to a switch 126, which appear to support Defendant's position. E.g., 6:22-29 (description of Figure 5 noting that the pump and the valve, "when present, are on when activated by the controller (or switch)
Nonetheless, the intrinsic evidence does not require the interpretation of the term "controller" as an "activation mechanism for said pump and said valve." First, much like with the plain language of the claims, the specification itself describes that the controller is connected to the pump and the valve and thus, while this may imply a certain function of the controller, it does not necessarily become a limitation of what the device is. Given that the specification describes the connection, the definition of the actual device need not to do so. Second, as the patent specification makes clear, the valve may be omitted. See 6:26 ("valve
Plaintiff cites to www.merriam-webster.com for the following definition of "controller": "a device or piece of equipment used to operate a machine, vehicle, or system." Ferris June 30, 2014 Decl., Ex. M. This definition is not particularly helpful to the resolution of the dispute. Defendant cites to no extrinsic evidence in support of its proposed construction of "controller."
I agree with Plaintiff that the proper construction of "controller" is "an activation mechanism." First, the additional language proposed by Defendant is redundant and unnecessary. Second, "controller" as used in Claim 18 does not need Defendant's proposed additional language to differentiate it from other uses of the word "controller" appearing in the claims. And, third, the Figures and specification do not demonstrate that "controller" must be narrowed beyond it being "an activation mechanism."
Plaintiff proposes construing the phrase "connected to" as "interacting directly or indirectly with." Jt. Prop. Claim Constr. Chart at 9. Defendant's proposal is: "electrically joined, united, or linked to."
Defendant notes that Claim 18 refers to "connected to" once and only to describe the relationship between the controller and the pump and the valve. Claim 18 also uses the phrase "in fluid communication with" three times in describing the relationships between the cavity's reservoir and the pump, between the pump and the valve, and between the valve and the wound site. Defendant argues that the claim language plainly shows that "connected to" describes a different relationship than the relationship disclosed by "in fluid communication with." From this, Defendant argues that because it is obvious that the "in fluid communication with" relationship is physical or mechanical, the "connected to" relationship has to mean something different. If it has to mean something other than physical or mechanical, it must mean electrical.
While Defendant may be correct that the phrases describe different relationships, there is nothing in the actual language of Claim 18 that compels the conclusion that the "connected to" relationship is an electrical relationship. Claim 18 does not create the "either/or" proposition advocated by Defendant. The invention requires a physical connection for the fluid to travel between the reservoir and the wound site, with connections to the pump and the valve in between. The invention cannot function otherwise. But, there is nothing in Claim 18 to show that the patentee intended to limit "connected to" to an electrical connection just because the "in fluid communication with" relationship describes a physical connection. "Connected to" is a broad term.
This is made clear by looking at Claim 19 which depends from Claim 18:
14:15-21.
The patentee, having already disclosed that the wound site is "in fluid communication" with the valve in Claim 18, more specifically delineates here that the "fluid communication" claimed in Claim 18 is accomplished by a conduit connected to the valve and the wound site. Given the nature of the invention, this has to mean a physical attachment of the conduit to the valve and the wound site to allow the "fluid communication" disclosed in Claim 18 to occur. Thus, the patentee uses the term "connected to" to mean a physical attachment or connection of conduit. The fact that the patentee used "in fluid communication with" as well as "connected to" in Claim 18 does not mean that a physical or mechanical connection is represented only by the phrase "in fluid communication with." As Claim 19 shows, "connected to" encompasses a physical or mechanical connection.
Defendant next points to Claim 4 which claims the trauma training system according to Claim 2, "wherein said at least one valve includes a solenoid electrically connected to said controller." 11:65-67. Defendant argues that this, the only claim that describes the connection between the controller and the valve, makes clear that the connection is electrical.
I disagree. Claim 4 depends from Claim 2 which depends from Claim 1. Thus, the claim starts with the reservoir, the pump, and the valve being "in fluid communication" with each other and the controller "connected to" the pump and the valve. 11:45-50. Then, in Claim 2, a wound site is added and it is "in fluid communication" with the valve "wherein fluid is provided to said wound site to simulate a hemorrhage." 11:55-57. In Claim 4, the valve previously claimed in Claim 1 is said to "include[] a solenoid electrically connected to said controller." 11:66-67.
The fact that the patentee added the word "electrically" indicates that Claim 1's previous description of that connection between the valve and the controller was not necessarily electrical. As explained above, under the doctrine of claim differentiation, the presence in the dependent claim of a particular limitation, such as "electrically," gives rise to the presumption that the limitation in question is not present in the independent claim. Phillips, 415 F.3d at 1315. Similarly, the fact that the patentee added that the valve was a solenoid valve means that the valve previously delineated in Claim 1 did not have to be solenoid. Because Claim 4 depends from Claims 2 and 1, it includes the distinguishing limitations of an electrical connection and the use of a solenoid valve. Thus, the "connected to" phrase in Claim 1, which is nearly identical to the "connected to" phrase in Claim 18, is not limited to an electrical connection.
The claim language does not support Defendant's proposed inclusion of the word "electrically."
Defendant notes that several of the '852 Patent Figures show solid lines as "connections" between the reservoir and flow controller, between the flow controller and the wound sites, and between the controller/activation mechanism 126 and the pump and the valve.
However, in Figures 2A, 2B, and 2C, the controller/activation mechanism 126 is connected to a power source, and in Figures 3 and 5, the "remote control switch," or "switch," both designated as 126, are shown connected to a power supply. Defendant argues that based on these Figures, the patentee disclosed that the controller/activation mechanism 126 serves as an activation mechanism for the pump and the valve by directing electrical power from the power supply to the pump and the valve. Defendant also points to Figures 6B and 6C to argue that they "clearly show an electrical connection between the power supply (130), the controller (126) and the valve (124)[.]" Def.'s Op. Claim Constr. Brief at 25. The depictions are not as clear as Defendant characterizes. Figure 6B depicts only the pump, but not the power supply, the controller/activation mechanism, or the valve. While it does show what appear to be wires coming out of the pump, none of the other devices are present. Figure 6C shows the controller/activation mechanism 126 connected to a power supply as well as a valve, by what appear to be wires, but the connections are not identified. Thus, Figures 6B and 6C are ambiguous.
Next, Defendant relies on the specification, and in particular, the following passage describing Figure 2A:
4:39-55.
Defendant argues that this passage shows that the scope of the invention is one of a controller electronically connected to the pump and also to the valve. While the specification says that the controller may include switches and dials, Defendant contends that those switches, buttons, or dials activate or regulate the controller but do not disclose a mechanical connection between the controller and the pump or between the controller and the valve. Thus, while the controller may be activated mechanically or physically by a switch, button, or dial, the connection from the controller to the devices it connects to is electrical.
Based on the Figures and the description, Defendant argues that the intrinsic evidence clearly establishes an electrical connection between the controller and the pump and the valve. There is never a reference to a hand pump, for example, or any other method, other than electrically, by which the pump is activated. Although some of the Figures support Defendant's position, and the quoted portion of the specification relied on by Defendant also supports Defendant's position, other references in the specification instruct that the term "connected to" should not be limited to an electrical connection.
In describing Figures 3 and 4, the specification discusses the flow controller's connection to a pair of wound sites. The illustration in Figure 3, the specification explains, includes a T-connector or Y-connector or manifold, connected to the valve for providing two fluid streams to the wound sites. 5:22-25. Figure 4 illustrates the fluid flow controller connected to the conduit for moving the fake blood to the abdomen wound site on a mannequin. 5:25-28. The conduit for each wound site is connected to the T-connector through needle valves which control the amount of fluid sent to the two respective wound sites. 5:28-32. Importantly, the specification then states that "[n]eedle valves, . . . although illustrated as being manual valves may be electrically controlled." 5:32-34. It goes on to say that "[a]lthough needle valves are illustrated in FIG 4, these valves can be any valve that allows for fluid volume control including electrically controlled valves, which have the added benefit of fluid flow adjustment (via a remote controller
In describing the flow controller in Figure 5, the specification provides that
6:30-44 (underlining emphasis added).
These parts of the specification undermine Defendant's argument because they expressly refer to the manual control of valves. Defendant acknowledges that other valves are described in the '852 Patent and shown in the Figures, but Defendant contends that they are described as "manual `needle valves' and simply not controllable by the controller." Def.'s Resp. Claim Constr. Brief at 15 (citing 5:28-41). As I understand Defendant's argument, the manually operated valves are independent of and not connected to a controller. But, once the invention discloses a valve connected to a controller, it is an electrical connection. Thus, when construing "connected to" in Claim 18, the description of the controller connected to the pump and the valve discloses an electrical connection.
Defendant's argument overlooks that there are two references to the manual adjustment of valves, one of which is not to the "needle valves" Defendant attempts to distinguish.
Plaintiff cites to www.merriam-webster.com which Plaintiff states defines "connect" as "to place or establish in a relationship." Ferris May 30, 2014 Decl., Ex. 9. But, that source lists several other definitions as primary, including: (1) "to join or fasten together usually by something intervening"; (2) "to join (two or more things) together"; (3) "to join with or become joined to something else"; and (4) "to think of (something or someone) as being related to or involved with another person, thing, event or idea."
Plaintiff also cites to the American Heritage dictionary to suggest that the proper definition of "connected" is "related; associated." But, the primary definition in that source is "[j]oined or fastened together." Ferris May 30, 2014 Decl., Ex. 2 at 4. That source also defines "connect," as opposed to "connected," as "[t]o join or fasten together."
Defendant cites to dictionary.com which defines "connect" as "to join, link, or fasten together; unite or bind[.]" www.dictionary.com.
I construe "connected to" to mean "joined, united, or linked to." For the reasons explained above, the claim language supports Plaintiff's position that "connected to" should not be limited to an electrical connection. While many references in the specification and the Figures suggest that the connection between the controller and the pump and the valve is electrical, the specification expressly discloses manually adjustable valves. Adopting Defendant's limitation of electrical is an improper "reading in" of the limitation from various exemplary embodiments and the Figures because in the end, the specification and the Figures do not require that "connected to" be limited to an electrical connection.
While I omit "electrical," I reject Plaintiff's proposal of "interacting directly or indirectly with." I agree with Defendant that Plaintiff's proposal is unnecessarily broad and vague. Moreover, it is not supported by the dictionary sources which provide primary definitions closer to Defendant's proposal.
The entire claim phrase of "controller connected to" is properly construed as "an activation mechanism joined, united, or linked to."
IT IS SO ORDERED.
