`
`
`
`DECLARATION OF SHIGERU ITOH
`
`Case No. IPR2019-00123
`__________________________________________________________________
`
`
`
`
`
`
`
`COOK
`Exhibit 1022-0001
`
`

`

`
`
`
`1. My name is Shigeru Itoh and I have personal knowledge of the facts
`
`contained in this declaration. I am a Japanese patent attorney (Benrishi) at Itoh &
`
`Ebi based in Tokyo, Japan. My work responsibilities include identifying
`
`references that are prior art to patents, including investigating the public
`
`accessibility of such references.
`
`2.
`
`I have been retained by the law firm of Brinks Gilson & Lione to
`
`provide this declaration concerning the Titanium / Zirconium Journal, Vol. 30, No.
`
`4 (October 1982) (the “Journal”). The Journal is a periodical that was published at
`
`regular intervals. I have been informed that an article published in the Journal will
`
`be relied upon by Petitioners in an inter partes review proceeding before the Patent
`
`Trial and Appeal Board of the U.S. Patent and Trademark Office.
`
`3.
`
`I have been asked to search for a copy of the Journal at the National
`
`Diet Library (the “Library”) located in Tokyo, Japan, and to determine the date
`
`when the Journal was publicly accessible.
`
`4.
`
`I am knowledgeable about the date-stamping, indexing, cataloging,
`
`and shelving procedures for journals acquired by the Library. Generally, after a
`
`journal is received in the mail, it is labeled with the date the journal is processed
`
`(referred to as a date stamp) by the Library’s Recording Section of the Domestic
`
`Material Division of the Collection Department. The date stamp is added to the
`
`journal to identify the date that the journal is received and processed by the
`
`
`
`
`COOK
`Exhibit 1022-0002
`
`

`

`
`
`Library, and the date on which the date stamp is added is the same date reflected in
`
`the date stamp. The date stamp is added by the Library personnel processing the
`
`journal who has knowledge of the then-current date on which the journal is
`
`processed.
`
`5.
`
`The journal is then sent (typically within one day of the date of the
`
`date stamp) from the Recording Section to the Journal Section of the Publications
`
`Division of the Collection Department. The Journal Section indexes the journal in
`
`the Library’s catalog system, and shelves the journal (typically within one day
`
`following receipt of the journal from the Recording Section). After shelving, the
`
`journal is accessible by the public interested in the subject matter of the journal.
`
`The journal with its date stamp is a record of the Library’s regularly conducted
`
`activity. Also, the journal with its date stamp is kept by the Library in the course
`
`of regularly conducted activity of the Library, which includes maintaining
`
`publications for the public to access and review.
`
`6.
`
`I retrieved a copy of the Journal from the Library. The Journal is
`
`date-stamped November 26, 1982. The Journal is over twenty years old, it was
`
`prepared with its date stamp before January 1, 1998, it was in a condition that
`
`created no suspicion about its authenticity, and it was located in the place where it
`
`would be expected to be located. True and correct copies of an excerpt from the
`
`Journal, including the date-stamped cover carrying the Table of Contents, is
`
`
`
`
`COOK
`Exhibit 1022-0003
`
`

`

`
`
`attached as Exhibit A. As reflected in the Table of Contents, Pages 1-8 of this
`
`journal constitutes the article entitled, Shape Memory and Super-elasticity Effects
`
`in NiTi Alloys, by Yuichi Suzuki. A true and correct copy of this article (along
`
`with its translation) has been designated as Ex. 1012 in this proceeding.
`
`7.
`
`The Journal was locatable on the Library’s shelves (at least by
`
`December 3, 1982 (within a week’s time after the Journal’s date stamp)) through
`
`the Library’s card catalog system that existed before the computerized catalog
`
`became available. This card catalog system was searchable by title, subject matter,
`
`and authors or editors, among other bibliographic information, and it identified
`
`where in the Library a journal was shelved. Upon identification of the journal
`
`using the Library’s card catalog system, a Library patron could then request a
`
`Library employee to retrieve the journal from the location where it was shelved,
`
`and the Library employee would retrieve the journal and provide it to the patron.
`
`8.
`
`To the best of my knowledge, the copy of the Journal that I retrieved,
`
`including the article identified above contained in the Journal, was indexed in, and
`
`locatable through, the Library’s card catalog system (such as by searching the card
`
`catalog by subject matter), and it was available to the public for viewing and
`
`making copies by December 3, 1982 (within a week’s time after the Journal’s date
`
`stamp).

`
`I have been warned that willful false statements and the like are
`
`punishable by fine or imprisonment, or both. I declare under penalty of perjury
`
`under the laws of the United States of America that the foregoing is true and
`
`correct.
`
`Executed September 26, 2018, at Tokyo, Japan.

`Shape Memory and Super-elasticity

`
`Effects in NiTi Alloys
`
`Summary: The equiatomic or near equiatomic NiTi is a unique intermetallic compound. It has good ductility, a
`
`shape memory effect, and a super-elasticity. The alloy undergoes a martemitic transformation at near room temper-
`
`ature. The low temperature phase is characterized by high damping capacity, and the high temperature phase by
`
`excellent abrasion and corrosion resistance. By a shape memory effect we mean that the alloy plastically deformed
`
`in the low temperature phase recovers its original shape in subsequent heating. Super-elasticity is a rubber-like
`
`behavior of the alloy in which a strain attained beyond the elastic limit in loading recovers upon unloading. The
`
`following is a presentation of the general properties and deformation mechanisms of the shape memory effect and
`
`the super-elasticity of the NiTi alloys including its applications such as in jointing devicu, thermal actuators, and
`medical devices.
