Scope
The Second Screen Working Group PAG has the scope to:
- explore ways to obtain an RF licensing commitment from the current owner of disclosed patent claims so that the W3C Royalty-Free Patent Policy Requirements are met;
- seek relevant prior art;
- discuss ways to design around the disclosed patents;
- if necessary, request an analysis of the claim by a W3C patent counsel. This analysis will be made only if sufficient funds for that purpose are made available via the Web Legal Support Fund.
Deliverable
This PAG is chartered to recommend to the W3C CEO a path forward following the identified disclosures. The recommendations must be chosen from among the options in section section 7.5.1 of the Patent Policy:
- The initial concern has been resolved, enabling the Working Group to continue.
- The Working Group should be instructed to consider designing around the identified claims.
- The Team should seek further information and evaluation, including and not limited to evaluation of the patents in question or the terms under which W3C RF licensing requirements may be met.
- The Working Group, or its work on the Specification(s) at issue, should be terminated.
- The Specification (if it has already been issued) should be rescinded.
- Alternative licensing terms should be considered. The procedure in section 7.5.3 must be followed.
