`
`The Mui Patents
`
`
`These nine patents generally cover devices and methods related to a universal
`
`remote control. The patents belong to four patent families, each family sharing a
`common specification.
`
`A.
`
`The parties refer to the ’642 Patent, the ’389 Patent, and the ’325 Patent
`
`collectively as “the Mui Patents.” The Mui Patents generally describe systems for using
`a “remote control device” in combination with, for instance, a “key code generator
`device” to control a user appliance. The remote control device and key code generator
`device respond to a pressed key on the remote control device by transmitting signals
`back and forth between the remote control device, key code generator device, and user
`appliance in various ways.
`
`UEI alleges that Roku infringes Claims 3, 6, 23, and 25 of the ’642 Patent. UEI
`
`Op. Br. at 1. Claims 3 and 6 depend from Claim 1. Claims 23 and 25 depend from Claim
`2. Claim 1 recites:
`
`
`1. A method comprising:
`(a) receiving a keystroke indicator signal from a remote control
`device, wherein the keystroke indicator signal indicates a key on said
`remote control device that a user has selected;
`(b) generating a key code within a key code generator device using
`the keystroke indictor signal;
`(c) modulating said key code onto a carrier signal, thereby generating
`a key code signal; and
`(d) transmitting said key code signal from said key code generator
`device to said remote control device.

`
`The ’853 Patent
`
`
`B.
`
`The ’853 Patent (also referred to by the parties as the “Arling Patent”) generally
`
`relates to “methods for appliance control” by using “a controlling device, such as a
`remote control, smart phone, tablet computer, etc.” ’853 Patent at 1:63–64. In particular,
`and similar to the Mui Patents, the ’853 Patent discloses a Universal Control Engine
`(“UCE”) that uses various methods to transmit a command function from the controlling
`device to the target appliance. Id. at 2:29–33.
`
`UEI alleges that Roku infringes Claim 5 of the ’853 Patent. UEI Op. Br. at 1.
`
`Claim 5 depends on Claim 1, which recites:
`

`
`The Scott Patents
`
`D.
`
`The parties refer to the ’532 Patent and the ’446 Patent as the “Scott Patents.” The
`
`Scott Patents also relate to a user interface on a universal remote control, and
`particularly to programming a remote control to work with a particular user device and a
`network in a proscribed manner. See, e.g. ’532 Patent, 1:1–17.
`
`Specifically, the claims of the ’532 Patent generally relate to an application on the
`
`remote that allows users to set up and execute a sequence of instructions. Id. at 10:40–
`61. UEI alleges that Roku infringes Claim 10 of the ’532 Patent. UEI Op. Br. at 2. Claim
`10 recites:
`
`
`10. A method for automatically creating a sequence of instructions to be
`executed by a controlling device, comprising:

`
`
`
`
`II. LEGAL STANDARD
`
`A. General Claim Construction Principles
`
`Claim construction is “exclusively within the province of the court.” Markman v.
`
`W. Instruments, Inc., 517 U.S. 370, 372 (1996). Such construction “must begin and
`remain centered on” the claim language itself. Interactive Gift Express, Inc. v.
`Compuserve, Inc., 256 F.3d 1323, 1331 (Fed. Cir. 2001). But extrinsic evidence may
`also be consulted “if needed to assist in determining the meaning or scope of technical
`terms in the claims.” Pall Corp. v. Micron Separations, Inc., 66 F.3d 1211, 1216 (Fed.
`Cir. 1995).
`
`In construing the claim language, the Court begins with the principle that “the
`
`words of a claim are generally given their ordinary and customary meaning.” Phillips v.
`AWH Corp., 415 F.3d 1303, 1312 (Fed. Cir. 2005) (en banc) (internal quotation marks
`omitted). This ordinary and customary meaning “is the meaning that the [claim] 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 effective filing date of the patent application.” Id. at 1313.
`“[T]he person of ordinary skill in the art is deemed to read the claim term not only in the
`context of the particular claim in which the disputed term appears, but in the context of
`the entire patent, including the specification.” Id.
`
`Date August 7, 2019
`
`“In some cases, the ordinary meaning of claim language as understood by a person
`of skill in the art may be readily apparent even to lay judges, and claim construction in
`such cases involves little more than the application of the widely accepted meaning of
`commonly understood words. In such circumstances general purpose dictionaries may
`be helpful.” Id. at 1314 (internal citation omitted). In other cases, “determining the
`ordinary and customary meaning of the claim requires examination of terms that have a
`particular meaning in a field of art.” Id. Then “the court looks to those sources available
`to the public that show what a person of skill in the art would have understood disputed
`claim language to mean.” Id. (internal quotation marks omitted). These sources include
`“the words of the claims themselves, the remainder of the specification, the prosecution
`history, and extrinsic evidence concerning relevant scientific principles, the meaning of
`technical terms, and the state of the art.” Id. (internal quotation marks omitted).
`
`But it is improper to read limitations from the specification into the claim.
`Callicrate v. Wadsworth Mfg., Inc., 427 F.3d 1361, 1368 (Fed. Cir. 2005) (“[I]f we once
`begin to include elements not mentioned in the claim, in order to limit such claim . . . we
`should never know where to stop.”) (quoting Phillips, 415 F.3d at 1312). A court does
`“not import limitations into claims from examples or embodiments appearing only in a
`patent’s written description, even when a specification describes very specific
`embodiments of the invention or even describes only a single embodiment, unless the
`specification makes clear that ‘the patentee . . . intends for the claims and the
`embodiments in the specification to be strictly coextensive.’” JVW Enters., Inc. v.
`Interact Accessories, Inc., 424 F.3d 1324, 1335 (Fed. Cir. 2005) (internal citations
`omitted) (emphasis added).

`
`B. Means Plus Function Claims
`
`Under 35 U.S.C. § 112(6),1 means-plus-function claiming occurs when an element
`
`in a claim is a “means or step for performing a specified function without the recital of
`structure, material, or acts in support thereof . . . .” In that case, “such claim shall be
`construed to cover the corresponding structure, material, or acts described in the
`specification and equivalents thereof.” Id. This provision allows “patentees to express a
`claim limitation by reciting a function to be performed rather than by reciting structure
`for performing that function . . . .” Williamson v. Citrix Online, LLC, 792 F.3d 1339,
`1347 (Fed. Cir. 2015) (en banc). At the same time, it constrains “how such a limitation is
`to be construed, namely, by restricting the scope of coverage to only the structure,
`materials, or acts described in the specification as corresponding to the claimed function
`and equivalents thereof.” Id.
`
`The failure to use the term “means” creates a rebuttable presumption that § 112(6)
`
`does not apply. See Advanced Ground Info. Sys., Inc. v. Life360, Inc., 830 F.3d 1341,
`1347 (Fed. Cir. 2016). To overcome this presumption a challenger must show “that the
`claim term fails to recite sufficiently definite structure or else recites function without
`reciting sufficient structure for performing that function.” Id. (quoting Williamson, 792
`F.3d at 1348). The challenger must establish § 112(6)’s applicability by a preponderance
`of the evidence. Skky, Inc. v. MindGeek, s.a.r.l., 859 F.3d 1014, 1019 (Fed. Cir. 2017).
`
`Once a court concludes that a term is subject to § 112(6), it follows a two-step
`
`process. Williamson, 792 F.3d at 1351. “First, the court must determine the claimed
`function. Second, the court must identify the corresponding structure in the written
`description of the patent that performs the function.” Noah Sys., Inc. v. Intuit Inc., 675
`F.3d 1302, 1311 (Fed. Cir. 2012) (internal citations omitted). “Where there are multiple
`claimed functions . . . the patentee must disclose adequate corresponding structure to
`perform all of the claimed functions. If the patentee fails to disclose adequate
`corresponding structure, the claim is indefinite.” Williamson, 792 F.3d at 1351.
`
`
`
`
`1 § 112(6) was renamed as § 112(f) by the America Invents Act, Pub. L. No. 112–29 (“AIA”), which
`took effect on September 16, 2012. Because the inventors here applied for the patents-in-suit before the
`act’s passage, § 112(6) applies.

`
`Case No.
`Title
`
`A corresponding structure is one that the specification or prosecution history
`
`“clearly links . . . to the function recited in the claim.” Id. The specification’s disclosure
`of a corresponding structure “must be of adequate corresponding structure to achieve the
`claimed function.” Id. (internal quotations omitted). “If a person of ordinary skill in the
`art would be unable to recognize the structure in the specification and associate it with
`the corresponding function in the claim, a means-plus-function clause is indefinite.” Id.
`
`For cases “involving a special purpose computer-implemented means-plus-
`
`function limitation,” the disclosed structure must “be more than simply a general
`purpose computer or microprocessor.” Noah, 675 F.3d at 1312. Instead, the specification
`must “disclose an algorithm for performing the claimed function.” Id. (quoting Net
`MoneyIN, Inc. v. VeriSign, Inc., 545 F.3d 1359, 1367 (Fed. Cir. 2008)). “The
`specification can express the algorithm ‘in any understandable terms including as a
`mathematical formula, in prose, or as a flow chart, or in any other manner that provides
`sufficient structure.’” Id. (quoting Finisar Corp. v. DirecTV Grp., Inc., 523 F.3d 1323,
`1340 (Fed. Cir. 2008)).

`8; ’325 Patent, Claim 1)
`
`
`UEI’s Construction
`
`“a signal containing a
`
`key code”
`
`
`
`
`
`Court’s Construction
`
`“signal containing
`
`a modulated key
`code”
`
`
`
`Roku’s Construction
`
`“a signal, for controlling a
`
`specific type, brand,
`and model of consumer
`electronic device, and
`which contains a modulated
`key code. Excludes
`signals containing key codes
`to be stored on the
`remote control for later use
`in generating IR signals.”
`
`The parties have three primary arguments regarding the meaning of the term “key
`code signal.” First, the parties dispute whether the claimed key code signal must always
`contain a modulated key code. Second, the parties dispute whether the key code signal
`must be “for controlling a specific type, brand, and model of consumer electronic
`device.” Third, the parties dispute whether the specification and prosecution history of
`the Mui Patents require that the key code signal “[e]xcludes signals containing key codes
`to be stored on the remote control for later use in generating IR signals.”
`
`
`
`a) modulation
`
`
`The asserted claims of the ’642 Patent and the asserted claims of the ’389 Patent
`
`already require that the claimed key code signal is modulated. Claim 1 of the ’642

`
`Patent, for instance, states “modulating said key code onto a carrier signal, thereby
`generating a key code signal.” ’642 Patent, Claim 1. However, this requirement does not
`appear in the asserted claims of the ’325 Patent. Claim 1 of the ’325 Patent, for instance,
`states, “format the key code for transmission to the second device; and transmit the
`formatted key code to the second device in a key code signal via use of the transmitter.”
`’325 Patent, Claim 1. The claim language itself would thus suggest that the phrase “key
`code signal” should not necessarily be limited to require that it contains a modulated key
`code.
`
`Roku relies on the specification to support its argument that the term “key code
`
`signal” as it appears in the ’325 Patent claims must also be limited to containing a
`modulated key code. Roku emphasizes its position that “key code signal” is a coined
`term. It then refers to disclosed embodiments in the specification where the key code
`signal includes a modulated key code.
`
`At the hearing, UEI argued that Figure 4 of the Mui Patents shows an example of
`
`a key code signal that has not been modulated and simply includes a key code with the
`addition of a start bit, parity bit, and stop bit:

`
`’642 Patent, FIGS. 4, 5. However, in describing the figures, the specification includes
`the following description:
`
`FIG. 4 and FIG. 5 illustrate key code signal 19 in two specific
`embodiments. In both embodiments, the key code is transmitted as a stream
`of digital values 010100011100, where the system code is transmitted first
`immediately followed by the key data without any place holders between
`them. The standardized system code determined in step 102 need not
`identify the brand or model of VCR 13, but only the fact that first electronic
`consumer device 13 is a VCR. The key code is modulated in step 103 using
`timing information associated with the codeset for VCR 13. Thus, the
`particular brand and model of VCR 13 is able to understand the key code
`modulated using the appropriate timing information.
