`
`INTRODUCTION
`
`Petitioner, listed above, filed a Petition requesting an inter partes
`
`review of claims 1–10, 12, 13, and 15–18 (“the challenged claims”) of
`
`U.S. Patent No. 6,895,449 B2 (Ex. 1001, “the ’449 patent”). Paper 1
`
`(“Pet.”). Patent Owner, Papst Licensing GmbH & Co., KG, filed a
`
`Preliminary Response. Paper 6 (“Prelim. Resp.”).
`
`For the reasons that follow, we institute an inter partes review as to all
`
`the challenged claims.
`
`A. Related Matters
`
`The parties indicate that the ’449 patent in cases taking place in
`
`several district courts. Pet. 4; Paper 5, 4–5. This patent has also been
`
`challenged in several other petitions for inter partes review. Pet. 4-5; Paper
`
`5, 2–4.
`
`B. The ’449 Patent
`
`The ’449 patent describes interface devices for communication
`
`between a computer host device and a data transmit/receive device (e.g., a
`
`multi-meter, transmitting measured data to a computer). Ex. 1001, 1:13–17,
`
`1:49–55. According to the ’449 patent, using a specific driver to match very
`
`closely to an individual host system would achieve high data transfer rates
`
`across the interface, but the specific driver cannot be used with other host
`
`systems. Id. at 1:66–2:11. Several solutions to this problem were known in
`
`the art. Id. at 2:15–3:20. For example, IOtech introduced an interface
`
`device for laptops, using a plug-in card for converting the personal computer
`
`2
`
`
`
`IPR2017-00415
`Patent 6,895,449 B2
`
`
`
`memory card association (PCMCIA) interface into a known standard
`
`interface (IEEE 1284). Id. at 2:18–23. The plug-in card provided a printer
`
`interface for enhancing data transfer rates. Id. at 2:23–27. In another
`
`example, a floppy disk drive interface was used for connecting a host device
`
`to a peripheral device. Id. at 3:4–8. The interface appeared as floppy disk
`
`drive to the host, allowing a floppy disk drive and another peripheral device
`
`to be connected to the host device. Id. at 3:11–13.
`
`The ’449 patent indicates that the “invention is based on the finding
`
`that both a high data transfer rate and host device-independent use can be
`
`achieved if a driver for an input/output device customary in a host device” is
`
`utilized. Id. at 3:27–31. Figure 1 of the ’449 patent, reproduced below,
`
`illustrates a block diagram of an interface device.
`
`As shown in Figure 1 above, interface device 10 connects to a host
`
`device via host line 11, and to a data transmit/receive device via output line
`
`16. Id. at 4:46–62. Interface device 10 includes first connecting device 12,
`
`second connecting device 15, digital signal processor 13, and memory
`
`
`
`3
`
`
`
`IPR2017-00415
`Patent 6,895,449 B2
`
`
`
`means 14. Id. In a preferred embodiment, the interface device is attached to
`
`a host device via a multi-purpose interface—e.g., a small computer systems
`
`interface (SCSI) interface—which includes both an interface card and
`
`specific driver software for the interface card. Id. at 3:44–50, 8:37–41.
`
`According to the ’449 patent, SCSI interfaces were known to be present on
`
`most host devices or laptops. Id. at 8:30–34. By using a standard interface
`
`of a host device and by simulating an input/output device to the host device,
`
`the interface device “is automatically supported by all known host systems
`
`without any additional sophisticated driver software.” Id. at 11:28–32.
`
`C. Illustrative Claim
`
`Of the challenged claims, claims 1, 17, and 18 are independent.
`
`Claims 2–10, 12, 13, 15, and 16 depend directly or indirectly from claim 1.
`
`Claim 1 is illustrative:
`
`1. An interface device for communication between a host device,
`which comprises drivers for input/output devices customary in a
`host device and a multi-purpose
`interface, and a data
`transmit/receive device comprising the following features:
`
`a processor;
`
`a memory;
`
`a first connecting device for interfacing the host device with the
`interface device via the multi-purpose interface of the host
`device; and
`
`a second connecting device for interfacing the interface device
`with the data transmit/receive device,
`
`wherein the interface device is configured by the processor and
`the memory in such a way that the interface device, when
`receiving an inquiry from the host device as to the type of a
`4
`
`
`
`IPR2017-00415
`Patent 6,895,449 B2
`
`
`
`device attached to the multi-purpose interface of the host device,
`sends a signal, regardless of the type of the data transmit/receive
`device attached to the second connecting device of the interface
`device, to the host device which signals to the host device that it
`is a storage device customary in a host device, whereupon the
`host device communicates with the interface device by means of
`the driver for the storage device customary in a host device, and
`
`wherein the interface device is arranged for simulating a virtual
`file system to the host, the virtual file system including a
`directory structure.

`Ex. 1001, 11:46–12:6.

`
`II. ANALYSIS
`
`A. Claim Construction
`
`In an inter partes review, claim terms in an unexpired patent are given
`
`their broadest reasonable construction in light of the specification of the
`
`patent in which they appear. 37 C.F.R. § 42.100(b). Under the broadest
`
`reasonable interpretation standard, claim terms generally are given their
`
`ordinary and customary meaning, as would be understood by one of ordinary
`
`skill in the art in the context of the entire disclosure. See In re Translogic
`
`Tech., Inc., 504 F.3d 1249, 1257 (Fed. Cir. 2007).
`
`We note that only those claim terms and elements which are in
`
`controversy need to be construed, and only to the extent necessary to resolve
`
`
`
`1 Because the claims at issue have a filing date prior to March 16, 2013, the
`effective date of the Leahy-Smith America Invents Act, Pub. L. No. 112-29,
`125 Stat. 284 (2011) (“AIA”), we apply the pre-AIA version of 35 U.S.C.
`§§ 102, 103, and 112 in this Decision.
`
`6
`
`
`
`IPR2017-00415
`Patent 6,895,449 B2
`
`
`
`the controversy. Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795,
`
`803 (Fed. Cir. 1999). The parties propose constructions for several claim
`
`terms. Pet. 11–13; Prelim. Resp. 7–9. For purposes of this Decision, we
`
`find it necessary to address only the claim terms “multi-purpose interface”
`
`and “data transmit/receive device.”
`
`“multi-purpose interface”
`
`Independent claim 1 recites “a first connecting device for interfacing
`
`the host device with the interface device via the multi-purpose interface of
`
`the host device.” Ex. 1001, 11:5456. The Specification of the ’449 patent
`
`describes “the interface device according to the present invention is to be
`
`attached to a host device by means of a multi-purpose interface of the host
`
`device which can be implemented, for example, as an SCSI interface or as
`
`an enhanced printer interface.” Id. at 3:44–48. The Specification also
`
`indicates that SCSI interfaces were known to be present on most host
`
`devices or laptops. Id. at 8:33–34. In light of the Specification, we construe
`
`the claim term “multi-purpose interface” to encompass a “SCSI interface.”
`
`“data transmit/receive device”
`
`All the challenged claims require a “data transmit/receive device.”
`
`Ex. 1001, 11:46–50, 13:14–17, 14:8–12. Petitioner proposes a broadest
`
`reasonable construction of “a device capable of transmitting or receiving
`
`data.” Pet. 12. Patent Owner, however, explains that the U.S. Court of
`
`Appeals for the Federal Circuit has not contradicted a district court
`
`construction of this term as a device that “is capable of either
`
`(a) transmitting data to or (b) transmitting data to and receiving data from
`
`7
`
`
`
`IPR2017-00415
`Patent 6,895,449 B2
`
`
`
`the host device.” Prelim. Resp. 8 (citing In re Papst Licensing GmbH & Co.
`
`KG v. Fujifilm Corp., 778 F.3d 1255, 1265–68 (Fed. Cir. 2015); Ex. 2002).
`
`Patent Owner argues that although the Federal Circuit applied the Phillips
`
`standard, the disclosure of the ’449 patent dictates that same construction
`
`under the broadest reasonable construction. Id.
`
`Petitioner does address the district court’s construction or explain why
`
`its proposed definition is reasonable in light of the ’449 patent’s disclosure.
`
`Pet. 12. Instead, Petitioner simply points to the ’449 patent’s statement “a
`
`data transmit/receive device which is to receive data from the host device or
`
`from which data is to be read, i.e. acquired, and transferred to the host
`
`device.” Id. (quoting Ex. 1001, 4:55–59) (emphasis added by Petitioner).
`
`This statement, however, does not limit the capabilities of a data
`
`transmit/receive device, and therefore also supports the district court’s
`
`construction.
`
`It is not clear that there is a meaningful difference between the parties’
`
`positions as it relates to the analysis below. To the extent, however, that
`
`Petitioner is proposing a construction that would not require a data
`
`transmit/receive device to be capable of transmitting data as long as it is
`
`capable of receiving data, we are not persuaded, at this point in the
`
`proceedings, that we should deviate from the district court construction. The
`
`district court construction is not inconsistent with the ’449 Specification.
`
`For example, the ’449 patent describes “a data transmit/receive device from
`
`which data is to be acquired or with which two-way communication is to
`
`take place.” Ex. 1001, 1:13–17. Thus, for purposes of this Decision, we
`
`8
`
`
`
`IPR2017-00415
`Patent 6,895,449 B2
`
`
`
`adopt as the broadest reasonable construction a device that “is capable of
`
`either (a) transmitting data to or (b) transmitting data to and receiving data
`
`from the host device.”
`
`B. Level of Ordinary Skill in the Art
`
`In determining the level of ordinary skill in the art, various factors
`
`may be considered, including the “type of problems encountered in the art;
`
`prior art solutions to those problems; rapidity with which innovations are
`
`made; sophistication of the technology; and educational level of active
`
`workers in the field.” In re GPAC, Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995)
`
`(citation omitted). In that regard, Dr. Ameroth testifies that a person having
`
`ordinary skill in the art at the time of the invention “would have [had at
`
`least] a four-year degree in electrical engineering, computer science, or a
`
`related field of study,” and “either a Master’s degree, or at least two years of
`
`experience in one of the relevant fields, computer science, computer
`
`systems, or peripheral devices.” Pet. 8–9 (citing Ex. 1003 ¶¶ 45–49.)
`
`Patent Owner confirms that Petitioner’s statements regarding the level
`
`of ordinary skill in the art is at least partially consistent with Patent Owner’s
`
`view, but nonetheless contends that an ordinarily skilled artisan would have
`
`“a bachelor’s degree in a related field such as computer engineering or
`
`electrical engineering and at least three years of experience in the design,
`
`development, and/or testing of hardware and software components involved
`
`with data transfer or in embedded devices and their interfaces with host
`
`systems.” Prelim. Resp. 6–7. Alternatively, Patent Owner states that a
`
`9
`
`
`
`IPR2017-00415
`Patent 6,895,449 B2
`
`
`
`person of ordinary skill “may have five or more years of experience in these
`
`technologies, without a bachelor’s degree.” Id. at 7.
`
`We do not observe any meaningful differences between the parties’
`
`definition of a person of ordinary skill in the art. Our analysis in this
`
`Decision is supported by either level of skill. We further find that the prior
`
`art in the instant proceeding reflects the level of ordinary skill in the art at
`
`the time of the invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355
`
`(Fed. Cir. 2001).
`
`C. Obviousness over Murata, Schmidt, and MS-DOS Encyclopedia
`
`Petitioner asserts that claims 1–3, 6–10, 12, 13, and 15–18 (all the
`
`challenged claims except claims 4 and 5) are unpatentable under 35 U.S.C.
`
`§ 103(a) as obvious over Murata combined with Schmidt and MS-DOS
`
`Encyclopedia. Pet. 7, 18–60. We determine that Petitioner has established
`
`that there is a reasonable likelihood that Petitioner would prevail with
`
`respect to this ground of unpatentability.
`
`Overview of Murata
`
`Murata discloses an image scanner used with an external host
`
`computer. Ex. 1005, Abs. According to Murata, the image scanner includes
`
`an optical system and CCD image sensor for reading an image of a
`
`document, a SCSI interface for connecting the image scanner to the external
`
`host, a CPU, a nonvolatile memory, and a “SCSI controller etc. for
`
`emulating a file system contained in the external host computer.” Id. An
`
`10
`
`
`
`IPR2017-00415
`Patent 6,895,449 B2
`
`
`
`object of Murata is “to provide an improved image handling apparatus . . .
`
`which requires no preparation of any new device driver.” Id. at 1:58–61.
`
`Figure 3 of Murata is reproduced below.
`
`
`
`Figure 3 of Murata is a block diagram of an image scanner. Id. at 2:40. It
`
`includes CCD image sensor 31, which “carries out main-scanning” by
`
`reading reflected light from a document and converting it to analog electric
`
`signal 32. Id. at 3:12–27. Analog image signal 32 is then amplified by
`
`amplifier 33 and converted to digital signal 35 by A/D converter 34. Id. at
`
`3:27–29. After the signal has traversed the rest of the scanner elements,
`
`SCSI controller 64, controlled by CPU 50, transfers data to and from the
`
`external host computer. Id. at 3:29–4:11.
`
`11
`
`
`
`IPR2017-00415
`Patent 6,895,449 B2
`
`
`
`Murata explains that “[b]ecause an operating system of a computer
`
`constructs a file system in a hard disc, there invariably exists a device driver
`
`for the hard disc.” Id. at 2:5–7. Moreover, because Murata’s image scanner
`
`includes a file system emulation means, control of the image scanner or
`
`transfer of image data “can be carried out using the device driver for existing
`
`hard discs” meaning “it is not necessary to prepare the device driver for each
`
`type of computer if the file system of the computer is the same.” Id. at 2:12–
`
`21. In short, the image scanner “can be connected to any one of various
`
`types of computers having the same file system, e.g. any one of all
`
`computers having software called the ‘UNIX’ as an operating system.” Id.
`
`at 18–26.
`
`Overview of Schmidt
`
`
`
`Schmidt describes the SCSI bus and IDE (Integrated Drive
`
`Electronics) interface, both of which are ANSI (American National
`
`Standards Institute) standards. Ex. 1006, Preface. According to Schmidt,
`
`these interfaces are two of the most important interfaces for computer
`
`peripherals in use at that time, and almost all computers at that time, from
`
`PCs to workstations to mainframes, were equipped with a SCSI interface.
`
`Id. The SCSI bus is designed for hard drives, as well as tape drives, CD-
`
`ROM, scanners, and printers. Id.
`
`Overview of the MS-DOS Encyclopedia
`
`
`
` The MS-DOS Encyclopedia is a book describing both the
`
`development and programming of MS-DOS. Ex. 1010, Preface. It describes
`
`12
`
`
`
`IPR2017-00415
`Patent 6,895,449 B2
`
`
`
`MS-DOS and Microsoft Windows 95 as “the most widely used computer
`
`operating system in the world.” Id. According to MS-DOS Encyclopedia,
`
`MS-DOS supported a large number of different peripherals. Id. at 59.
`
`Analysis
`
`Petitioner relies on Murata as disclosing the majority of limitations
`
`required by the challenged claims. To demonstrate its mapping of Murata to
`
`the challenged claims, Petitioner creates an annotated version of Murata’s
`
`Figure 3. Pet. 23. Petitioner’s annotated Figure 3 is reproduced below.
`
`
`
`13
`
`
`
`IPR2017-00415
`Patent 6,895,449 B2
`
`
`
`Id. Petitioner explains that elements 33–65 of scanner 20, as shown in
`
`Murata’s Figure 3, comprise the claimed interface device. Id. at 24.
`
`According to Petitioner, SCSI controller 64 is the claimed “first connecting
`
`device” for interfacing with workstation 21, the “host device.” Pet. 23–24.
`
`Petitioner relies on amplifier 33 and A/D converter 34 together as the
`
`claimed “second [interfacing] device” for interfacing with CCD 31, the “data
`
`transmit/receive device.” Id. Petitioner then explains how Murata discloses
`
`the rest of the limitations of the challenged claims. Id. at 24–60.
`
`Petitioner relies on Schmidt to provide a detailed discussion of a SCSI
`
`device recognition process because “Murata does not describe all of the
`
`details of the operation of SCSI, the communication protocol used to
`
`facilitate the transfer of information or all the details about an operating
`
`system that would be used.” Id. at 18. According to Petitioner, a person of
`
`ordinary skill, understanding that Murata discloses a scanner that connects to
`
`a workstation via SCSI, would have looked to “a reference, like Schmidt, to
`
`provide details of the SCSI bus initialization process between a host
`
`computer and a peripheral device that involve the peripheral device.” Pet.
`
`18–19 (citing Ex. 1003, ¶ 55). “Schmidt serves only to provide the
`
`foundation for what knowledge a POSA would have had with regard to
`
`SCSI.” Ex. 1003 ¶ 55.
`
`Petitioner relies on the MS-DOS Encyclopedia because Murata
`
`describes a scanner connected to a host computer running the Unix operating
`
`system. Pet. 19–20 (citing Ex. 1003 ¶ 56). According to Petitioner, MS-
`
`DOS and Microsoft Windows 95, in the 1997 timeframe, were more popular
`
`14
`
`
`
`IPR2017-00415
`Patent 6,895,449 B2
`
`
`
`operating systems on personal computers. Id. To reach a larger customer
`
`base, therefore, a person of ordinary skill would have been motivated to
`
`implement Murata using a computer running MS-DOS or Microsoft
`
`Windows. Id. Petitioner adds that both MS-DOS and SCSI, were, at the
`
`time, well-established and well-documented and it was known they worked
`
`together. Pet. 20 (relying on Ex. 1003 ¶ 57, which cites Ex. 1006, 240).
`
`Thus, Petitioner concludes that a person of ordinary skill would have had a
`
`reasonable expectation of success and would find the implementation of
`
`Murata for MS-DOS, instead of Unix, as a routine exercise. Id.
`
`We determine that Petitioner, on this record, provides sufficient
`
`evidence to show a reasonable likelihood of prevailing on its contention that
`
`Murata, Schmidt, and the MS-DOS encyclopedia together disclose all the
`
`limitations of the challenged claims. On the current record, Petitioner also
`
`provides a reasonable rationale for how and why a person of ordinary skill
`
`would combine the teachings.
`
`Patent Owner argues that the asserted prior art does not disclose the
`
`claimed data transmit/receive device. Patent Owner argues that a charge
`
`coupled device (CCD) is, by definition, “an electronic device operated by
`
`charge, especially one which converts photons of light into a digital signal,
`
`converting an optical image into a digital image.” Prelim. Resp. 20 (quoting
`
`Ex. 2003). According to Patent Owner, a CCD is not required to allow for
`
`the transmission of data to a host device. Id. Petitioner, however, points out
`
`that Murata states that CCD 31 “reads an image of a document placed on a
`
`document platform, converts the read image to an electric signal, and outputs
`
`15
`
`
`
`IPR2017-00415
`Patent 6,895,449 B2
`
`
`
`an analog image signal 32.” Pet. 22 (citing Ex. 1005, 3:24–27, Fig. 2; Ex.
`
`1003 ¶ 64). Moreover, Murata discloses that after some more processing,
`
`that image is transferred to an external host computer via SCSI controller 64.
`
`Id. (citing Ex. 1005, 4:12–16; Ex. 1003, ¶¶ 65–66). We are persuaded, on
`
`this record, that Petitioner sufficiently shows that Murata discloses CCD 31
`
`is capable of transmitting data to a host device and, thus, qualifies as the
`
`claimed “data transmit/receive device” as we have construed that term. Ex.
`
`1005, 3:24–27; 4:12–16.
`
`Patent Owner also argues that Petitioner does not sufficiently explain
`
`why Murata, Schmidt, and the MS-DOS Encyclopedia would have been
`
`combined by a person of ordinary skill. Prelim. Resp. 17. According to
`
`Patent Owner, Petitioner’s explanation “is merely conclusory analysis
`
`without any evidence that a SCSI bus, such as described in Murata, would
`
`necessitate the use of the Schmidt interface adaptor.” Id. at 19. We,
`
`however, are persuaded that Petitioner’s rationale is sufficient for purposes
`
`of institution. Petitioner explains, in some detail, that a person of ordinary
`
`skill would have known the information set forth in Schmidt and the MS-
`
`DOS Encyclopedia and why they would have been motivated to apply that
`
`knowledge to the invention described by Murata. Pet. 18–20.
`
`Conclusion
`
`In view of the foregoing, we determine that Petitioner has
`
`demonstrated a reasonable likelihood of prevailing on its assertions that
`
`claims 1–3, 6–10, 12, 13, and 15–18 are unpatentable as obvious under
`
`16
`
`
`
`IPR2017-00415
`Patent 6,895,449 B2
`
`
`
`§ 103(a) over Murata, in combination with Schmidt and the MS-DOS
`
`Encyclopedia.
`
`D. Obviousness over Murata, Schmidt, MS-DOS Encyclopedia, and Beretta
`
`Petitioner asserts that claims 4 and 5 are unpatentable under § 103(a)
`
`as obvious over Murata, Schmidt, MS-DOS Encyclopedia, and Beretta.
`
`Pet. 60–65. Claims 4 and 5 depend from claim 2, which in turn depends
`
`from claim 1. Claim 4 further recites “wherein the executable file includes a
`
`Fast Fourier Transform routine for transforming data acquired by the second
`
`connecting device into the frequency domain for examining frequency
`
`domain data.” Ex. 1001, 12:15–19. Claim 5 recites “wherein the executable
`
`file includes a data compression routine for compressing data to be
`
`transmitted form the data transmit/receive device to the host.” Id. at 12:20–
`
`23. Patent Owner, in its Preliminary Response, does not raise any separate
`
`argument with regard to claims 4 and 5 other than those already addressed
`
`above in connection with the other challenged claims.
`
`Petitioner, on this record, provides sufficient evidence to show that
`
`Beretta discloses the additional limitations recited in claims 4 and 5.
`
`Notably, Petitioner explains that Murata discloses improved methods for
`
`compressing images. Pet. 60–61 (citing Ex. 1007, 4:44–46, 4:65–67; Ex.
`
`1003, ¶ 155). Petitioner adds that a person of ordinary skill in the art would
`
`have enhanced Murata’s scanner with Beretta’s improved compression
`
`algorithms because Beretta teaches that its methods were designed and
`
`intended to be used to compress images produced by scanners. Id. at 61–62
`
`(citing Ex. 1007, 4:65–67, 5:39–63; Ex. 1003 ¶ 157).

`Patent 6,895,449 B2
`
`
`
`Based on the evidence currently in this record, we are persuaded that
`
`Petitioner has articulated a sufficient rationale to combine the teaching of
`
`Murata, Schmidt, the MS-DOS Encyclopedia, and Beretta. See KSR Int’l
`
`Co. v. Teleflex, Inc., 550 U.S. 398, 417 (2007) (noting that “if a technique
`
`has been used to improve one device, and a person of ordinary skill in the art
`
`would recognize that it would improve similar devices in the same way,
`
`using the technique is obvious unless its actual application is beyond his or
`
`her skill”).
`
`III. CONCLUSION
`
`For the foregoing reasons, we determine that there is a reasonable
`
`likelihood that Petitioner would prevail in challenging claims 1–10, 12, 13,
`
`and 15–18, as unpatentable under § 103(a). At this point in the proceeding,
`
`we have not made a final determination with respect to the patentability of
`
`the challenged claims, nor with respect to claim construction.
`
`For the foregoing reasons, it is
`
`IV. ORDER
`
`ORDERED that pursuant to 35 U.S.C. § 314(a), an inter partes
`
