Patent Policy

The Patent slides were offered for review.

No new claims were disclosed at the call for essential patent claims.

Agenda Approval

Motion by Jarek, seconded by Ray. Motion is approved.

Previous Minutes

John moved and Dave G seconded the approval of the September 19, 2011 minutes. The motion was approved.

Action Item Review

Steven reviewed the open action items.

The email ballot for self-assessment has passed

Liaison Reports

John reported that P1076 has closed the officer election and Jim Lewis is the new chair.


John updated the TWiki Use Cases page to document the Digital Envelope with Licensing use case. This additional page should close out the work on this use case, unless the working group finds some additional issues to resolve.

License Management

Michael raised concerns with the security risks from a transparent reference implementation for license management. John agreed, but noted that the purpose was to provide a practical demonstration of the protocol and we should clearly state the low level of protection provided.

Dave G offered to work with Michael in looking at some possible prior art for a reference implementation.

Key Management

Rights Management

Dave G reported productive internal meetings discussing then next contribution round for working group review. He anticipates a discussion in the next meeting.

Common Rights and Visibility

John believes we will find consensus on common rights involving visibility, licensing, error handling. and output control. Past discussions around generalized activity classes leave some room for agreeing on the common rights related to those classes.

Other Business

Dave G asked about language context and concerns about implementation consistency:
  • include file processing
  • macro processing

John noted that IP Authors might want to control the mode of macro processing within encrypted regions, and that we should understand the desires and how we might support that.

Steven offered some background on lexical processing strategies and will forward that to Dave for use in his internal discussions.

Jarek raised concerns about security in use cases documented in P1800. He offered to post his mind-mapping documentation derived from his internal review of the EDA encryption standards.
