`I.
`
`INTRODUCTION AND STATEMENT OF RELIEF REQUESTED
`The Board’s Final Written Decision (“Decision” or “Dec.”) of September
`
`19, 2017 (Paper 41), was largely decided on a claim construction issues that is
`
`contradicted by the specification and other intrinsic evidence for U.S. Pat. No.
`
`8,559,635 (the “’635 Patent”). Much of the analysis in the Decision is one-sided
`
`and appears results-oriented.
`
`Patent Owner submits that this Request for Rehearing (“Request”) should be
`
`granted because the Decision misapprehended and overlooked evidence provided
`
`and arguments made by Patent Owner regarding the proper construction of
`
`“decrypt.” The term “decrypt” (or variations such as “decrypting,” “encrypted,”
`
`etc.) is found in each of the challenged claims. Patent Owner asks that the Board
`
`grant this Request, vacate the Decision and issue a new Final Written Decision
`
`correcting the claim construction and confirming the affected claims as patentable.
`
`The construction of this term by the Board is incorrect as a matter of law.
`
`First, the Decision ignored key passages from the specification, whose meanings
`
`are undisputed, and compounded the error by instead focusing on a passage whose
`
`meaning is disputed to support its construction.
`
`Second, the Board’s claim construction completely disregarded multiple
`
`instances of prosecution disclaimer. The prosecution disclaimers could not be
`
`1
`
`
`
`Case No.: IPR2016-00754
`Patent No.: 8,559,635
`
`more clear and unequivocal.
`II. LEGAL STANDARDS
`A request for rehearing “must specifically identify all matters the party
`
`believes the Board misapprehended or overlooked, and the place where each
`
`matter was previously addressed in a motion, an opposition, or reply.” 37 C.F.R.
`
`§ 42.71(d)
`
`Under the broadest reasonable interpretation standard, “claims should
`
` always be read in light of the specification and teachings in the underlying
`
`patent,” and the meaning of a claim must “reasonably reflect the plain language
`
`and disclosure” instead of being “unreasonably broad.” Microsoft Corp. v.
`
`Proxyconn, Inc., 789 F.3d 1292, 1298 (Fed. Cir. 2015); 37 C.F.R. § 42.100.
`
`
`
`Thus, in construing a term, the PTAB should consider: (1) the ordinary and
`
`customary meaning (if one exists); (2) the claim language; (3) the specification;
`
`and (4) the prosecution history. Tempo Lighting, Inc. v. Tivoli, LLC, 742 F.3d 973,
`
`977 (Fed. Cir. 2014); see Phillips v. AWH Corp., 415 F.3d 1303, 1312-1313 (Fed.
`
`Cir. 2005).
`III. THE CONSTRUCTION OF THE “DECRYPT” TERMS IS
`ERRONEOUS
`Each of the challenged claims recite various “decrypt” and “encrypt” type
`
`terms (“decrypt terms”).
`
`2
`
`
`
`Case No.: IPR2016-00754
`Patent No.: 8,559,635
`Patent Owner submitted that the “decrypt” terms should be construed to
`
`mean “a method that uses a digital key in conjunction with an associated
`
`algorithm to decipher (render intelligible or usable) digital data.” Patent Owner
`
`Response (“POR”), Paper 15, at 6 [emph. added.] Patent Owner explained that its
`
`construction excluded operations on analog information, such as the descrambling
`
`of analog television. Id.
`
`The Board determined that the “decrypt” terms are not limited to digital
`
`processes applied to digital data, but broadly encompass analog processes such as
`
`descrambling analog television. Dec. at 18. The Board did not proceed from an
`
`ordinary and customary meaning of the “decrypt” terms because there allegedly
`
`was no established meaning. Dec. at 13 (“The evidence shows the meaning of the
`
`terms to be in flux, with no established convention.”). For all intents and purposes,
`
`the Board’s construction of “decrypt” is based entirely on a single sentence in the
`
`‘635 Patent specification, described by the Board as “controversial.” Dec. at 9-10
`
`(citing Ex. 1003, 160:51–55).
`
`The Board erred by failing to consider the specification as a whole,
`
`including passages at odds with the Board’s construction. The Board also refused
`
`to consider multiple disclaimers in the file history that are independently
`
`dispositive of the issue.
`
`3
`
`
`
`Case No.: IPR2016-00754
`Patent No.: 8,559,635
`A. The Specification Defines “Decrypt” to Mean a Digital Process on
`Digital Data, Excluding Analog Processes such as the
`Descrambling of Analog Television.
`The Federal Circuit has stated time and again that the specification is the
`
`primary source for ascertaining the meaning of claim terms. In Phillips v. AWH
`
`Corp. , the Federal Circuit stated:
`
`The specification is, thus, the primary basis for construing the claims.
`On numerous occasions since then, we have reaffirmed that point,
`stating that “[t]he best source for understanding a technical term
`is the specification from which it arose, informed, as needed, by the
`prosecution history.
`
`415 F.3d 1303, 1315 (emph. added, cites omitted). This maxim was reaffirmed in
`
`the Federal Circuit’s decision reversing the Board in In re Smith Int’l, Inc., --- F.3d
`
`----, 2017 WL 4247407 (Fed. Cir. Sept. 26, 2017) at *5 (proper construction is that
`
`which “corresponds with what and how the inventor describes his invention in the
`
`specification”) [cite omitted].
`
`
`
`A mere two passages in the specification should have decided the issue for
`
`“decrypt.” First, the ‘635 Patent specification describes the “decrypt” term as
`
`follows:
`
`Decryptors, 107, 224 and 231, are conventional decryptors, well
`known in the art, with capacity for receiving encrypted digital
`information, decrypting said information by means of a selected
`cipher algorithm and a selected cipher key, and outputting the
`decrypted information.
`
`4
`
`
`
`Case No.: IPR2016-00754
`Patent No.: 8,559,635
`Ex. 1003 (‘635 Patent, emp. added) at 148:11-16; see POR at 7.
`
`
`
`The passage is definitional. The inventors understood the term to have a
`
`meaning in the art which they set forth explicitly and adopted as their own. The
`
`Decision did not address this first passage.
`
`
`
`Second, the ‘635 Patent affirmatively defines decryption as being distinct
`
`from analog descrambling:
`
`In the prior art, various means and methods exist for regulating the
`reception and use of electronically transmitted programming. Various
`scrambling means are well known in the art for scrambling, usually
`the video portion of analogue television transmissions in such a
`fashion that only subscriber stations with appropriate descrambling
`means have capacity to tune suitably to the television transmissions
`and display
`the
`transmitted
`television
`image
`information.
`Encryption/decryption means and methods, well known in the art,
`can regulate the reception and use of, for example, digital video and
`audio
`television
`transmissions, digital audio
`radio and
`phonograph transmissions, digital broadcast print transmission,
`and digital data communications.
`
`Ex. 1003 (‘635 Patent) at 144:7-19, POR at 8.
`
`
`
`
`
`This passage establishes a dichotomy: encryption/decryption apply to digital
`
`signals, whereas scrambling/descrambling apply to analog signals. It is consistent
`
`with the definition of “decrypt” set forth in the passage above. The Decision
`
`5
`
`
`
`Case No.: IPR2016-00754
`Patent No.: 8,559,635
`wholly ignored this passage from the specification in its analysis of the “decrypt”
`
`terms.
`
`
`
`While ignoring the passages that explicitly and indisputably define
`
`“decrypt,” the Board myopically focused on a single “controversial” passage at the
`
`end of a specific embodiment, Example #7. Example #7 (spanning thirteen
`
`columns) describes a complex embodiment for the decryption of a digital
`
`television transmission containing encrypted digital video and encrypted digital
`
`audio that has been encrypted using three separate keys. Ex. 1003 (‘635 Patent) at
`
`144:6-13, 23-31.
`
`
`
`At the end of the thirteen columns the specification lists a series of
`
`modifications that could be made to the Example #7 embodiment. One is:
`
`And for example, the “Wall Street Week” transmission
`may be of conventional analog television, and the decryptors,
`107, 224, and 231, may be conventional descramblers, well,
`known in the art, that descramble analog television transmissions
`and are actuated by receiving digital key information.
`
`Ex. 1003 at 160:51-55 [emph. added]; POR at 9-10.
`
`
`
`The Board based its claim construction on this single sentence, which the
`
`Board called a “controversial sentence.” Dec. at 10. The Board erroneously
`
`asserted that this “controversial sentence” defines “decrypt.”
`
`6
`
`
`
`Case No.: IPR2016-00754
`Patent No.: 8,559,635
`First, this sentence must be understood in the context of the introduction to
`
`
`
`the paragraph, which states:
`
`It is obvious to one of ordinary skill in the art that the foregoing is
`presented by way of example only and that the invention is not to be
`unduly restricted thereby since modifications may be made in the
`structure of the various parts without functionally departing from
`the spirit of the invention.
`
`Ex. 1003 at 160:40-45 [emph. added]. Accordingly, the “controversial
`
`sentence” can only be understood as a modification to the structure of the
`
`Example #7 embodiment: descramblers replace decryptors in the case of
`
`analog television. POR 11-13. The Board has improperly conflated a
`
`modification to the components of an embodiment with a “definition.”
`
`Next, the Board’s reliance on this one sentence is unreasonable. The
`
`premise that a “controversial sentence” susceptible to multiple
`
`interpretations can be a definition is false, particularly where, as here, the
`
`other passages in the specification (discussed above) define the “decrypt”
`
`term with clarity and without ambiguity. The Board improperly failed to
`
`consider these passages in its zeal to construct the term in a broadest
`
`possible construction, rather than the broadest reasonable construction based
`
`on what the specification teaches about the invention. The Board thus erred
`
`by failing to consider the specification as a whole.
`
`7
`
`
`
`Case No.: IPR2016-00754
`Patent No.: 8,559,635
`The passages at columns 144 and 148 of the ‘635 Patent provide a
`
`
`
`definition for the term. The “controversial sentence” cannot trump that
`
`definition.
`B.
`
`The File History Contains Multiple Disclaimers Limiting
`Decryption to Operations on Digital Data and Excluding Analog
`Processes.
`PMC cited to multiple instances of disclaimer during prosecution of the ‘635
`
`
`
`Patent and related patents with the same specification that limit “decrypt” to
`
`operations on digital data and exclude operations on analog information. POR at
`
`12-14.
`
`
`
`
`
`
`
`Disclaimers in ‘635 Patent
`
`First Disclaimer. The first disclaimer was made in an office action response
`
`on April 2, 2013, which stated: “Applicants have consistently asserted in their
`
`previous Responses . . . that encryption and decryption require a digital signal”
`
`and “encryption and decryption are not broad enough to read on scrambling
`
`and unscrambling.” POR at 12 (citing Ex. 2016 at 1330, emph. added). The
`
`inventors then distinguished the prior art on the basis that it described analog
`
`descrambling, not the decrypting recited by the claims that requires digital signals.
`
`Id. This disclaimer is clear and unequivocal. The Board did not address this
`
`disclaimer in the ‘635 Patent.
`
`
`
`Second Disclaimer. The inventors disclaimed analog descrambling from
`
`“decrypt” the first time these claims were introduced. In the office action response
`8
`
`
`
`Case No.: IPR2016-00754
`Patent No.: 8,559,635
`submitted on April 5, 2011, the inventors submitted new claims 23, 34, and 43,
`
`which correspond to the independent claims at issue. Ex. 2016 at 1008-1016. The
`
`inventors stated: “The claims of this amendment, however, claim material relating
`
`to the encryption and decryption of signals.” Id. at 1017. They stated that
`
`“encryption requires a digital signal” and “[e]ncryption and decryption . . . are
`
`not broad enough to read on scrambling and descrambling of analog signals.”
`
`Id. at 1018 [emph. added]. They also distinguished the art on the same basis:
`
`“Therefore, because [the references] are directed to the unscrambling of analog
`
`signals, none teach or suggest a method of controlling the decryption of digital
`
`information as is presented in the claims of this amendment.” Id. This disclaimer in
`
`the ‘635 Patent is clear and unequivocal.
`
`
`
`
`
`Disclaimers in ‘091 Patent
`
`The Board is aware of three separate disclaimers in U.S. 8,191,091 (‘091
`
`Patent) (assigned App. Ser. No. 08/485,507) that exclude descrambling of analog
`
`information from “decrypt.” Those disclaimers apply here because the ‘635 and
`
`‘091 Patents share the same specification and the same claim term is at issue.
`
`
`
`In an office action response which first introduced claims for the ‘091 Patent
`
`with “decrypt” terms, the inventors disclaimed analog descrambling:
`
`All [prior art] patents disclose the use of encoded control signals or
`other data to control the unscrambling of an analog video signal. . . .
`Each of the claims of this amendment involves the use of digital
`9
`
`
`
`Case No.: IPR2016-00754
`Patent No.: 8,559,635
`signals through reference to “decryption” and “encryption.”
`“Encryption and decryption,” . . . “are not broad enough to read on
`scrambling and unscrambling.”
`See Ser. No. 08/485,507, Supplemental Amendment, 4/11/11, at 10-11 [emph.
`
`added]. The same disclaimers occurred again in two other papers. See Ser. No.
`
`08/485,507, Amendment After Final, 10/3/2011, at 11 (“decryption requires a
`
`digital signal” and “encryption and decryption are not broad enough to read on
`
`scrambling and unscrambling.”); Ser. No. 08/485,507, Amendment and Request
`
`for Consideration, 12/21/11, at 10 (“decryption requires a digital signal” and
`
`“encryption and decryption are not broad enough to read on scrambling and
`
`unscrambling.”).
`
`
`
`The above disclaimers regarding the “decrypt” terms are clear and
`
`unequivocal.
`
`
`
`
`
`Disclaimers in ‘277 and ‘825 Patents
`
`The reexamination file histories of patents sharing the same specifications,
`
`U.S. Pat. No. 5,335, 277 (‘277 Patent) and 4,965,825 (‘825 Patent), have the same
`
`disclaimers. POR at 13-14. In the appeal briefing in the reexamination of the ‘277
`
`and ‘825 Patents, the inventors stated (all emph. added):1
`
`
`1 The Board disregarded the listed statements from the ‘277 briefing. Instead, it
`
`selectively plucked from another sentence referring to “decrypt” as “something
`
`10
`
`
`
`Case No.: IPR2016-00754
`Patent No.: 8,559,635
`• ‘277 Appeal Brief: “[D]ecryption … is a digital operation performed on
`
`digital signals, not analog signals. Descrambling of analog television
`
`signals does not correspond to decryption whatsoever, as is well
`
`understood in the art.” Ex. 2031 at 77.
`
`• ‘277 Reply Brief: “[O]ne of ordinary skill in the art would understand that a
`
`decryptor that decrypts signals as interpreted in light of the specification
`
`does not include analog scrambling and descrambling. . . . Here, the
`
`inventor expressly distinguished his use of the terminology
`
`encryption/decryption’ from the scrambling/descrambling shown in . . .
`
`the applied references.” Ex. 2006 at 41.
`
`
`beyond the conventional scrambling descrambling relied upon by the Examiner,
`
`such as the use of a decryption key . . .” Dec. at 14. The Board then asserted:
`
`“Patent Owner argues ‘encryption and decryption’ only differ ‘beyond . . .
`
`conventional scrambling/descrambling” by “the use of a decryption key.” Dec. at
`
`17. That statement is incorrect. The cited sentence simply reflects that decryption
`
`involves the use of a decryption key. Any other reading of that sentence conflicts
`
`with the repeated statements in the briefing that “decrypt” requires a digital signal
`
`and excludes analog descrambling.
`
`
`
`11
`
`
`
`Case No.: IPR2016-00754
`Patent No.: 8,559,635
`• ‘825 Appeal Brief: “Scrambling and encryption are different terms in
`
`the art. In particular, encryption relates to digital signals.” Ex. 2009 at 30.
`
`
`
`The Board Response. The Board does not analyze any of the multiple
`
`prosecution disclaimers, including the disclaimer in the prosecution of the ‘635
`
`Patent. The Board dismisses all prosecution disclaimers on the basis that such
`
`“general statements” disclaiming analog descrambling “do not account for the
`
`specific claim terms at issue in this proceeding.” Dec. at 16-17. No explanation is
`
`provided. The same encrypt/decrypt terms are at issue in each of the disclaimers. It
`
`is arbitrary and capricious for the Board to simply decree that none of the
`
`prosecution disclaimers “count.”
`C. The Board’s Inquiries into Irrelevant and Tangential Matters Do
`Not Cure Its Failure to Adhere to the Specification and
`Prosecution History.
`The Decision spends twelve pages addressing the construction of the
`
`“decrypt” terms. Dec. at 7-18. The correct result could be provided in a few pages
`
`by reference to the specification and prosecution history, which provide a ready
`
`answer. But the task of justifying an incorrect result requires more work. Perhaps
`
`this explains the Board’s various forays and detours into matters that are irrelevant
`
`or peripheral.
`
`For example, the Decision has a lengthy discussion about the meaning of the
`
`term “programming.” Dec. at 7-9. But the issue is the meaning of “decrypt,” not
`
`“programming.” The Board’s effort to use “programming” to bootstrap its
`12
`
`
`
`Case No.: IPR2016-00754
`Patent No.: 8,559,635
`preferred construction of “decrypt” is wrong at every level. The ‘635 Patent
`
`specification defines programming as “everything that is transmitted electronically
`
`to entertain, instruct or inform, including television, radio, broadcast print, and
`
`computer programming [as] well as combined medium programming.” Ex. 1003 at
`
`6:31-34. Programming is thus defined as types of content that “entertain, instruct,
`
`or inform.” Other than being transmitted “electronically,” the definition is agnostic
`
`as to how the content is delivered. “Programming” is not defined in terms of how it
`
`is formatted (e.g., analog or digital) or how it is transmitted (e.g., modulation,
`
`frequency, type of transmitter, etc.). Thus, the Board’s tortured argument that (1)
`
`“programming” is allegedly defined to include analog transmissions, and thus (2)
`
`“decrypting programming” must mean “decrypting analog transmissions,” and thus
`
`(3) “decrypting” encompasses descrambling analog transmissions, is erroneous
`
`from start to finish. Dec. at 7-9. This convoluted logic cannot overcome the clear
`
`teachings in the specification and file history.
`
`The Board quotes itself: “[I]f you say you don’t have anything about
`
`descrambling in there, then you must be talking about protecting [programs] with
`
`decrypting, which is the same thing as descrambling because [the programs
`
`include] analog.” Decision at 9 (citing to hearing). With all due respect, that
`
`conclusion is based on the incorrect premise that programs can only be “protected”
`
`by decryption or descrambling. In fact, there are many other ways to protect
`
`13
`
`
`
`Case No.: IPR2016-00754
`Patent No.: 8,559,635
`programs. See, e.g., Ex. 1004, Fig. 4 (interrupt means); 4:47-54 (special signal
`
`words); Ex. 1003 at 7:40-42 (“a variety of means and methods for restricting the
`
`use of transmitted communications to only duly authorized subscribers”); 144:19-
`
`28 (jamming and disabling unauthorized stations); 151:10-40 (tamper detection
`
`and disabling unauthorized stations).
`
`The Board’s discourse on the original patent, U.S. Pat. No. 4,965,490 (Ex.
`
`1004, “’490 Patent”) for claim construction is irrelevant.2 The determination of the
`
`meaning of claim terms is based only on the appended specification, the ‘635
`
`Patent CIP specification. See PowerOasis, Inc. v. T-Mobile USA, Inc., 522 F.3d
`
`1299, 1311 (Fed. Cir. 2008) (“[T]he construction of “customer interface’ that must
`
`be supported by the written description of the Original Application is the
`
`construction given by the district court for the term as used in the ′658 and
`
`′400 Patents [CIP Applications].”) [emph. added].
`
`The Board also cites Builders Concrete, Inc. v. Bremerton Concrete Prods.
`
`Co., 757 F.2d 255, 258 (Fed. Cir. 1985) for the notion that prosecution disclaimer
`
`is an “equitable tool” that the Board is free to disregard. Dec. at 18. Builders
`
`Concrete involves file history estoppel and is thus inapposite. Prosecution
`
`disclaimer is a tool for claim construction; file history estoppel is not. See
`
`2 The ‘490 Patent is relevant to whether it provides written decryption support for
`
`the priority inquiry (§ 112), but not the prerequisite step of claim construction.

`Patent No.: 8,559,635
`Southwall Technologies, Inc. v. Cardinal IG Co., 54 F.3d 1570, 1578 (Fed. Cir.
`
`1995) (limit on range of equivalents due to prosecution history estoppel is
`
`irrelevant to interpretation of those claims). The cited comment (id.) from Tempo
`
`Lighting, Inc. v. Tivoli, LLC, 742 F.3d 973 (Fed. Cir. 2014) is mere dicta.
