`preservation process of Exhibit 3. Upon confirmation, the Patentee raised no objection to
`
`the authenticity and publication date of all the exhibits, and the accuracy of Chinese
`
`translation of Exhibit 2.
`
`The Petitioner expounded in court the following views. Firstly, the Petitioner had no
`
`objection to the claim amendment. Secondly, in re the amended claim set, the Petitioner
`
`clarified that the observations and exhibits submitted by the Petitioner on August 7, 2017
`
`shall prevail as the grounds and exhibits for invalidation, the specific invalidation reasons
`
`still apply to the amended claims 1-17, and Rule 20.1 of the Implementing Regulations of
`
`the Patent Law shall apply to lack-of-clarity of the claims. To be specific, (1) the
`
`description lacks a sufficient disclosure, such that the technical solutions of claims 1-17

`

`

`cannot be enabled, contrary to Article 26.3 of the Patent Law; (2) claims 1-17 lack a clear
`
`scope of protection and thus do not conform to Rule 20.1 of the Implementing Regulations
`
`of the Patent Law; (3) claims 1-17 lack support in the description and thus do not conform
`
`to Article 26.4 of the Patent Law; (4) all invalidation reasons regarding novelty are
`
`withdrawn; and (5) claims 1-17 involve no inventive step in the sense of Article 22.3 of the
`
`Patent Law, specifically for the following reasons:
`
`independent claims 1 and 12 are not inventive in view of the combination of Exhibit 1 with
`
`general knowledge, or the combination of Exhibit 1, Exhibit 3 and general knowledge of
`
`the art, or the combination of Exhibit 1, Exhibit 2 and general knowledge, or the
`
`combination of Exhibit 2 and general knowledge, or the combination of Exhibit 2, Exhibit
`
`1 and general knowledge, or the combination of Exhibit 2, Exhibit 3 and general
`
`knowledge, or the combination of Exhibit 3 and general knowledge, or the combination of
`
`Exhibit 3, Exhibit 1 and general knowledge, or the combination of Exhibit 3, Exhibit 2 and
`
`general knowledge;
`
`the additional technical features of claims 5 and 14 are disclosed by Exhibit 1, or Exhibit 2,
`
`or Exhibit 3, or pertain to general knowledge in the art;
`
`the additional technical features of claims 2, 4, 16 and 17 are disclosed by Exhibit 1 or
`
`Exhibit 3 or pertain to general knowledge in the art;
`
`the additional
`
`technical features of claim 3 are disclosed by Exhibit 3 or by the
`
`combination of Exhibit 1, Exhibit 2 and general knowledge, or belong to general
`
`knowledge in the art;
`
`the additional
`
`technical features of claims 6 and 10 are disclosed by Exhibit 3 in

`

`combination with general knowledge, or pertain to general knowledge in the art;
`
`the additional technical features of claim 7 are disclosed by Exhibit 1, Exhibit 2 in
`
`combination with general knowledge, or by Exhibit 3 in combination with general
`
`knowledge, or pertain to general knowledge in the art;
`
`the additional technical features of claims 8 and 11 are disclosed by Exhibit 3 or belong to
`
`general knowledge in the art;
`
`the additional technical features of claim 9 are disclosed by Exhibit 1 in combination with
`
`general knowledge or by Exhibit 3 in combination with general knowledge, or pertain to
`
`general knowledge in the art; and
`
`the additional
`
`technical features of claim 13 and 15 are disclosed by Exhibit 1 in
`
`combination with general knowledge of the art, or by Exhibit 2 in combination with
`
`general knowledge of the art, or by Exhibit 3 in combination with general knowledge of the
`
`art, or pertain to general knowledge in the art.
`
`During the oral hearing, both parties fully aired their views on the basis of the written
`
`observations.
`
`Having gone through the procedures above, the Panel holds that the facts of this case are
`
`clear, and a decision can be made.
`
`II. Reasons for the decision
`
`1. The basis for collegiate examination and the application of laws

`
`

`

`The Patentee submitted on October 16, 2017 the amended claim set. Upon examination, the
`
`amendment is in compliance with Rule 69 of the Implementing Regulations of the Patent
`
`Law and the provisions of Guidelines for Examination as set forth in Part IV, Chapter 3,
`
`Section 4.6. As such,
`
`the instant Reexamination Decision is based on claims 1-17
`
`submitted by the Patentee on October 16, 2017.
`
`Pursuant to the transitional measures on implementing the amended Patent Law and the
`
`amended Implementing Regulations of the Patent Law, the Patent Law amended on August
`
`25, 2000 for the second time and the Implementing Regulations of the Patent Law
`
`amended on December 28, 2002 for the first time shall apply.
`
`2. In re the exhibits
`
`Exhibits 1 and 2 proffered by the Petitioner pertain to published patent literature. Exhibit 3
`
`is a master's thesis downloaded from the official website of CNKI, which website displays
`
`that the IT series of the full-text database of Chinese Excellent Master's Thesis have a
`
`publication date of July 16 to August 15, 2008. The Petitioner furnished the notarial deed
`
`2017-Jing-Guo-Xin-Nei-Min-Zheng-Zi No. 09419,
`
`justifying the
`
`source
`
`and the
`
`preservation process of Exhibit 3. The Patentee raised no objection to the authenticity and
`
`publication dates of Exhibits 1, 2 and 3. Upon verification, the Panel acknowledges the
`
`authenticity of Exhibits 1, 2 and 3, confirms that Exhibits 1, 2 and 3 were all published
`
`before the filing date of the subject patent and can serve as the prior art to evaluate the
`
`inventiveness of the subject patent, and determines that the Chinese translation of Exhibit 2
`
`submitted by the Petitioner shall prevail as the disclosure of Exhibit 2.
`
`3. With regard to Article 26.3 of the Patent Law

`

`

`Pursuant to Article 26.3 of the Patent Law, the description shall set forth the invention or
`
`utility model in a manner sufficiently clear and complete so as to enable a person skilled in
`
`the relevant field of technology to carry it out.
`
`(1) The Petitioner deems that:
`
`claims 1-17 all recite "associating two or more sessions with the composition session
`
`identifier by exchanging the composition session identifier"; however, the description of
`
`the subject patent neither discloses how "two or more sessions with the composition
`
`session identifier" are associated "by exchanging the composition session identifier", nor
`
`explicates which specific relationship between "two or more sessions" and "the
`
`composition session identifier" belongs to "association"; hence an insufficient disclosure.
`
`However, the Panel is of the following opinions. The description of the subject patent
`
`recites in paras. 0011, 0012, 0066 and 0067 that:
`
`The composition session identifier, if generated by the user equipment, or provided to the
`
`user equipment via a third party provider (such as via an Electronic Program Guide), may
`
`be sent to the network element where the session management takes place. Alternatively,
`
`the composition session identifier may be sent to the user equipment from or under control
`
`of the network elem
