CalConnect shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be provided in the Introduction.
Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.
This document was prepared by Technical Committee PUBLISH.
This document provides guidance on the implementation of the CalConnect patent policy (CC/DIR 10003) as applicable to internal process and procedures, especially in relation to the standardization and publication processes described in CC/DIR 10001.
CalConnect is committed in expanding the realm of standards in collaborative technologies with a focus on interoperability across the globe and communities of practice.
As a proponent of open standards, CalConnect has adopted a patent policy in CC/DIR 10003 to align IPR practice with major international standardization bodies including ISO, IEC and ITU.
The intent of this document is to:
encourage the early disclosure and identification of patents during the standardization and publication processes;
resolve potential patent concerns and rights problems relevant to the standardization and publication processes.
Guidelines for the implementation of the CalConnect patent policy
This document provides guidelines on the application of the CalConnect patent policy (CC/DIR 10003) towards the following areas of CalConnect:
standardization and publication process (described in CC/DIR 10001);
document requirements (described in CC/DIR 10001).
This document does not cover the implementation of requirements in CalConnect standards which involve intellectual property rights (such as patents).

4. Patent disclosure
This clause describes the principles of patent disclosure of patents that may affect CalConnect standardization deliverables produced by CalConnect.
This clause applies to any patent disclosed or drawn to the attention of CalConnect during the development of and subsequent to the approval of deliverables.
4.2.1. Participation obligation
All parties participating in the standardization activities of CalConnect are obligated to inform CalConnect of any known patent or to any known pending patent application, as mandated by CC/DIR 10003, Clause 1
Where such parties include recipients of a draft CalConnect standardization deliverable at any stage, and the patent or patent application could be of the party’s own or that of other entities.
4.2.2. Early disclosure
Patent information should be disclosed as early as possible during the development of the deliverable.
Such patent information should be provided in good faith and on a best effort basis. There is no requirement for patent searches.
NOTE This might not be possible when the first draft text appears since at this time, the text might be still too vague or subject to subsequent major modifications.
4.2.3. External-originating disclosure
Parties not participating in the standardization activities of CalConnect may also inform CalConnect to any known patent, either their own and/or of any third-party, that may cover a CalConnect deliverable.
4.3. Method of disclosure
4.3.1. Declaration form
When disclosing their own patents, patent holders shall fill in the “Patent Statement and Licensing Declaration Form” (referred to as the “declaration form”) as stated in Appendix A.
4.3.2. Third-party patent disclosure
Any communication drawing the attention to any third-party patent should be addressed to CalConnect in writing.
The Executive Director of CalConnect will then request the potential patent holder to submit a declaration form, if applicable.
4.4. Resolution to discriminatory licensing
If a patent holder is unwilling to license under CC/DIR 10003, Clause 2.1 or CC/DIR 10003, Clause 2.2, CalConnect will promptly advise the project owner(s) responsible for the affected deliverable so that appropriate action can be taken.
Such action shall include, but may not be limited to:
a review of the CalConnect standardization deliverable or its draft in order to remove the potential conflict; or
to further examine and clarify the technical considerations causing the conflict.
NOTE This clause does not differentiate whether identification of the patent took place before or after the approval of the deliverable.
5. Patent statement and licensing declaration form
The patent statement and licensing declaration form (see Appendix A) is provided for entities with information on how essential patents affect CalConnect deliverables (such as, patent holders) to provide accurate information in the CalConnect patent information database.
Entities shall report patent information to CalConnect using the CalConnect patent declaration form, which is available on the CalConnect website (see Appendix A).
The completed declaration form should be directly submitted to the designated contact provided on the form.
The declaration form also allows patent holders to make a licensing declaration relative to rights in patents required for implementation of a specific deliverable.
5.3. Declaration of patent license
Specifically, by submitting this declaration form, the submitting party declares, in accordance with the CalConnect patent policy, patents held by it and whose licence would be required to practice or implement part(s) or all of a specific deliverable:
its willingness to license (by selecting option 1 or 2 on the Form); or
its unwillingness to license (by selecting option 3 on the Form).
5.4. Additional information required due to unwillingness to license
If a patent holder has selected the licensing option 3 on the declaration form, then, for the referenced relevant CalConnect deliverable, CalConnect requires the patent holder to provide certain additional information permitting patent identification.
Multiple declaration forms are appropriate if the patent holder wishes to identify several patents and classifies them in different options of the declaration form for the same deliverable or if the patent holder classifies different claims of a complex patent in different options of the declaration form.
Information contained in a declaration form may be corrected in case of obvious errors, such as a typographical mistake in a standard or patent reference number.
5.5. Superseding license declarations
The licensing declaration contained in the declaration form remains in force unless it is superseded by another declaration form containing more favorable licensing terms and conditions from a licensee’s perspective reflecting:
a change in commitment from option 3 to either option 1 or option 2;
a change in commitment from option 2 to option 1; or
un-checking one or more sub-options contained within option 1 or 2.
5.5.1. Contact information
In completing the declaration form, attention should be given to supplying contact information that will remain valid over time:
“Name”, “Department” and “E-mail addresses” should be generic.
A single point of contact for a particular submitting party is preferred if multiple declaration forms are submitted (particularly for multinational organizations).
For maintaining the currency of information in the CalConnect patent information database, the patent declarer is urged to directly contact CalConnect on any change or corrections to declaration forms submitted, especially on the change of contact points.
5.6. Conduct of meetings
Early disclosure of patents contributes to the efficiency of the process by which deliverables are established.
Therefore, each technical body, in the course of the development of a proposed deliverable, will request the disclosure of any known patents essential to the proposed deliverable.
The leadership of technical body will, ask at an appropriate time in each meeting, whether anyone has knowledge of patents, the use of which may be required to practice or implement the deliverable being considered. The fact that the question was asked shall be recorded in the meeting report, along with any affirmative responses.
As long as CalConnect has received no indication of a patent holder selecting CC/DIR 10003, Clause 2.3, the deliverable may be approved with normal procedure. It is expected that discussions in technical bodies will include consideration of including patented material in a deliverable, however the technical bodies may not take position regarding the essentiality, scope, validity or specific licensing terms of any claimed patents.
5.7. Patent information database
In order to facilitate both the standards-making process and the application of deliverables, CalConnect makes available to the public a patent information database composed of information that was communicated to CalConnect by the means of declaration forms.
The patent information databases may contain information on specific patents, or may contain no such information but rather a statement about compliance with the patent policy for a particular deliverable.
The patent information databases are not certified to be either accurate or complete, but only reflect the information that has been communicated to CalConnect.
As such, the patent information databases may be viewed as simply raising a flag to alert users that they may wish to contact the entities who have communicated declaration forms to CalConnect in order to determine if patent licenses must be obtained for use or implementation of a particular deliverable.
5.8. Assignment or transfer of patent rights
The rules governing the assignment or transfer of patent rights are contained in the patent statement and licensing declaration forms (see Appendix A).
By complying with these rules, the patent holder has discharged in full all of its obligations and liability with regards to the licensing commitments after the transfer or assignment.
These rules are not intended to place any duty on the patent holder to compel compliance with the licensing commitment by the assignee or transferee after the transfer occurs.
6. Requirements on deliverables
6.1. Draft deliverables
