`
`SUPPLEMENTAL AMENDMENT
`
`MS Amendment
`Commissioner for Patents
`P.O. Box 1450
`Alexandria, VA 22313-1450
`
`Dear Sir:
`
`This application had been suspended since 2005 and held in abeyance from examination
`
`by the Office pending final action in a corresponding so-called "A" application, U.S. Patent
`
`Application, Serial No. 08/449,263. This suspension was based on an agreement made between
`
`Applicants and the Office to consolidate or group the claims of Applicants' then pending
`
`applications which had been filed prior to June 8, 1995, into a smaller number of applications.
`
`This so-called consolidation agreement resulted from a series of interviews conducted from
`
`November 1998 through June 1999 between Applicants' representatives and the Office. In those
`
`interviews, senior Office management suggested that further examination of this application and
`
`Applicants' other related applications could be expedited by reducing the number of pending
`
`applications. Accordingly, Applicants agreed to consolidate their claims into 56 subject matter
`
`groups and to reduce the number of pending applications accordingly. Applicants' agreement
`
`APPLE EX. 1034
`Page 1
`
`

`
`was based on the Office's view that it would be helpful to the Office to examine the claims of the
`
`subject matter groups together.
`
`For each subject matter group, the applications were separated based on whether priority
`
`was claimed to Applicants' initiall981 Application (U.S. Serial No. 06/317,510) or their initial
`
`1987 Continuation-in-Part Application (U.S. Serial No. 07/096,096). The claims from all
`
`applications in a group having the same priority claim were added to a single application
`
`designated an "A" application. The remaining applications were abandoned with the exception
`
`of one so-called "B" application corresponding to each "A" application.
`
`Under this agreement, the PTO suspended prosecution in the "B" applications pending
`
`final action in the corresponding "A" applications. Further, the parties agreed to conduct
`
`interviews in the "A" applications so that the prosecution of those applications could be
`
`efficiently advanced. Under the agreement, subject matter not found to be allowable during
`
`prosecution of an "A" application may be further prosecuted in the "B" application while the
`
`"A" application would be allowed to issue. In good faith reliance on this consolidation
`
`agreement, Applicants abandoned 169 of their 329 pending applications and filed numerous
`
`amendments adding to the designated "A" applications various claims that had been pending in
`
`the abandoned applications and the designated "B" applications. 1
`
`On May 9, 2000, Applicants amended the DECR 81 group "A" application, U.S. Patent
`
`Application Serial No. 08/449,263, in accordance with the aforementioned agreement. Claims
`
`from related DECR 81 applications were added to the DECR 81 group "A" application.
`
`1 As a result of the consolidation, Applicants paid excess claim fees for many of the claims that were added to the
`designated "A" applications, even though Applicants previously paid excess claim fees for those claims when
`they had been added to the abandoned applications and the designated "B" applications.
`
`2
`
`APPLE EX. 1034
`Page 2
`
`

`
`Applicants amended some of the "A" Claims on March 8, 2002. In late 2002 and early
`
`2003, reexamination requests were filed and granted as to Applicants' seven previously issued
`
`patents. Subsequent to the initiation of these reexamination proceedings, the Director of
`
`Technology Center 2600 decided to suspend prosecution of this application and the related "A"
`
`application pending resolution of the reexamination proceedings for the issued patents and the
`
`prosecution to appeal to the Board of Patent Appeals and Interferences ("Board") of two of
`
`Applicants' pending applications, (1) the INTE application (U.S. Patent Application, Serial No.
`
`08/470,571) and (2) the MULT application (U.S. Patent Application, Serial No. 08/487,526). As
`
`a result of this decision, the DECR 81 group "A" application (U.S. Patent Application, Serial No.
`
`08/449,263) was suspended through a number of six month Suspension Notices until January
`
`2009. Consequently, no formal response was made regarding the "A" Claims.
`
`In 2009, as the reexamination proceedings for Applicants' issued patents had been
`
`substantially completed and decisions had been issued by the Board in the INTE and MULT
`
`applications, Applicants requested that the suspension of their various applications be
`
`terminated.
`
`This request was granted in the spring of 2009 and, as a result, applicants met with
`
`Examiner Minh Dieu T. Nguyen for a number of personal interviews in January 2010. An
`
`agreement was made to cancel or amend numerous of the "A" Claims so that the DECR 81
`
`group "A" application (U.S. Patent Application Serial No.08/449,263) could issue.
`
`In the instant application, DECR 81 group "B" (U.S. Patent Application Serial No.
`
`08/449,413), Applicants filed a Supplemental Amendment Under 37 C.P.R. §1.115 on May 9,
`
`3
`
`APPLE EX. 1034
`Page 3
`
`

`
`2000. Applicants canceled all claims except for claim 2, which they amended. The Examiner
`
`then suspended the application according to the above mentioned consolidation agreement.
`
`Consistent with the consolidation agreement between the Applicants and the Office,
`
`Applicants now wish to pursue the subject matter within the scope of the "A" Claims of the
`
`DECR 81 group "A" application (U.S. Patent Application Serial No. 08/449,263) by claiming
`
`such subject matter that was not patented in the "A" application in the instant "B" application.
`
`Claims 22-55 correspond to various claims of the "A" application with additional amendments
`
`that Applicants believe place the claims in condition for allowance. In order to aid the Examiner
`
`in understanding the amendments to the claim, Applicants have attached a marked up copy of the
`
`claims (Appendix A) indicating the differences between the "A" Claims and the amended form
`
`submitted herein as claims 22-55.
`
`Applicants believe that claims 22-55 overcome the prior art, and should place the above(cid:173)
`
`identified patent application in condition for allowance. Applicants respectfully request
`
`favorable consideration of the above-identified patent application in view of the following
`
`remarks.
`
`Claim 2 which is currently pending in this application will be cancelled.
`
`Amendments to the claims begin on page 5.
`
`Remarks begin on page 14.

`
`Status of claims
`
`REMARKS
`
`New claims 22-55 have been added. They correspond to claims 2, 3, 4, 5, 6, 7, 8, 9, 10,
`
`11, 12, 19,21,40,41,42,43,44,89,93, 109,111,112,113,114,115,116,117,118,123,125,
`
`127, 131, and 134 of the DECR 81 group "A" application (U.S. Patent Application Serial No.
`
`08/449,263.) The newly presented claims are fully supported by the specification and do not
`
`introduce new matter.
`
`Each of the claims is patentable in light of the prior art. Prior patents Hartung (U.S.
`
`Patent No. 4,019,201), Tang (U.S. Patent No. 4,253,114), and Bond (U.S. Patent No. 4,390,898)
`
`were cited as having subject matter similar to some of the claims now introduced in claims 22-
`
`55. All three patents disclose the use of encoded control signals or other data to control the
`
`unscrambling of an analog video signal.
`
`The claims of this amendment, however, claim material relating to the encryption and
`
`decryption of signals. Claim 22 is "[a] method for controlling the decryption of encrypted
`
`programming" and contains a step of "decrypting said encrypted programming." Claim 23 is
`
`"[a] method for controlling the decryption of programming" and contains a step of "decrypting
`
`said encrypted digital information portion of said programming." Claim 24 contains a step of
`
`receiving an instruct signal that can operate to "decrypt said unit of programming or said first
`
`instruct signal." Claim 31 contains a step of receiving downloadable code that is effective to
`
`"implement a new technique of decrypting." Claim 33 contains a step of receiving instruct
`
`signals that are operative to "implement a new technique of decrypting." Claim 34 contains a
`
`step of "decrypting a second of said plurality of signals." Claim 40 contains a step of
`
`"controlling a decryptor to decrypt in a specific fashion" and a step of "decrypting at least one
`
`second signal of said plurality of signals." Claim 41 is a method to "detect digital data and
`
`14
`
`APPLE EX. 1034
`Page 14
`
`

`
`control a decryptor" and contains a step of "receiving digital data." Claim 42 contains a step of
`
`"decrypting at least one of said plurality of signals." Claim 43 is "[a] method for decryptor
`
`activation" and contains a step of "decrypting under first processor control a first portion of said
`
`encrypted materials." Claim 54 contains a step wherein a "decryptor decrypts said programming
`
`signal." Claim 55 contains a step of "controlling a decryptor" and a step of "decrypting or
`
`enabling communication of at least a second of said plurality of signals."
`
`The Board of Patent Appeals and Interferences decided in Ex parte Personalized Media
`
`Communications, LLC (Appeal 2008-4228, Ex parte Reexamination Control 90/006,536) at
`
`pages 53-54, that encryption requires a digital signal. Each of the claims of this amendment
`
`involves the use of digital signals either through reference to "digital" signals or through
`
`reference to "decryption" and "encryption." "Encryption and decryption," the Board goes on to
`
`say, "are not broad enough to read on scrambling and unscrambling." Therefore, because
`
`Hartung, Tang, and Bond are directed to 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.
`
`Upon entry of this paper, claims 22-55 will be pending and under consideration.
`
`Reconsideration is respectfully requested based on the above amendments.
`
`II.
`
`Conclusion
`
`Applicants respectfully submit that all claims are in condition for examination and
`
`prompt examination on the merits is earnestly requested. In the event Applicants have
`
`overlooked the need for an extension of time, payment of fee, or additional payment of fee,
