Re: [xrblock] after the IPR Disclosure related to draft-ietf-xrblock-rtcp-xr-video-lc

["Roni Even" <[e-mail]>]

Hi Alan,

I think that this is what the response says. According to IETF if you have IPR that relates to a document you must declare it. So this is what I understand from Rachel email.

Hi Rachel

For clarification - I suggested in January that the disclosing party be asked to verify that the IPR did (in their opinion) apply to the draft, not whether they had complied with the process. So really a question related to substance rather than form.

Best Regards

Alan

Hi,

 

Just to clarify that “We did not receive any answer to the request for further information”, the party that submitted the IPR responded by saying that the IPR statement was made in order to comply with the IETF IPR disclosure requirements, which I already copied in the previous mail.

Hi,

 

We did not receive any answer to the request for further information. 

 

At this point in time, we ask the working group to express their opinion about what to do with  draft-ietf-xrblock-rtcp-xr-video-lc.

 

We have two options: 

 

1.       Continue as planned with the approval and publication process

2.       Not proceed with this document. 

 

All WG participants – please express you preference for option #1 or option #2. 

 

Thanks and Regards,

 

Dan

Hi,

 

There was one answer to this mail (from Alan) expressing preference for option #1. Let us go with it. 

 

Rachel, it would be good if you can send your colleagues a reminder. 

 

Thanks and Regards,

Thanks, Rachel, for the information and for the efforts to clarify the issue with the legal affairs department at your company. 

 

We have a few more options about what to do next. 

 

1.  Wait a few more weeks for an answer with further information – I suggest no later than February 29, 2016

2. Proceed with the draft given the information available

3. Not proceed with the draft

 

All WG members – please express your preference. 

 

Thanks and Regards,

 

Dan

Dear all,

 

Sorry for so late response to the mailing list.

 

I have forwarded this IPR issue to our legal affairs department responsible for this IPR disclosure. However, I didn’t get any information for now. And I’m not sure if they have any that could be shared within the mailing list or not (We all know that IETF policy doesn’t require the company to analysis and verify the applying, which is what the legal team or even court  should do when meeting some legal problems). 

 

Meanwhile, I can’t do any clarification for them in public since we’re totally different departments. It will against our company’s law. …So it’s not within my control. Hope WG could understand that.

 

BR,

Rachel

Hi all,

 

Sorry for the late response. I’m in a business trip these two weeks with sporadic email access. So I may not respond timely. 

This IPR is from another department so I’m not quite familiar with it. I’ll invite the colleague who’s the IPR holder or responsible for the IPR disclosure to clarify in the mailing list. Hope we can find some way to solve this issue.

 

BR,

Rachel

Hi Dan

Within the IETF patent policy there is no requirement that I'm aware of that requires a disclosing company to prove that the patent they reference does in fact apply to the draft/RFC, which means that companies could make disclosure statements that don't actually apply to the referenced draft/RFC. In many larger companies the IPR/legal team may be distant from the engineering team and I've seen cases in which allegations of infringement were made based on a text match rather than a technical analysis. If, as WG members, we feel that a disclosure may be inappropriate based on a technical understanding of the draft/RFC and the patent then IMHO we should be willing to politely point this out - if the disclosing company wants to keep the disclosure anyway then we have to leave it to individual implementers to obtain their own legal advice; my view is that as WG members and authors we should try and keep the IPR situation as clear as possible.

I've encountered exactly this situation - my company develops software that analyzes voice/ audio/ video stream performance and as part of this we model the performance of a wide range of voice/ audio and video codecs. We have been contacted numerous times by companies that have codec IPR and who see that we analyze streams encoded with the G.xyz codec - we then have to explain that we don't actually implement the codec, only a parametric model.

So - my position is that we should ask Rachel, as an author and a representative of the disclosing company, to request that Huawei verify that their disclosure does, in their opinion, apply. 

Regards

Alan

Hi Alan,

 

The statement that was posted a few weeks back explicitly refers to this I-D – see https://datatracker.ietf.org/ipr/2725/ <https://urldefense.proofpoint.com/v2/url?u=https-3A__datatracker.ietf.org_ipr_2725_&d=BQMFbw&c=BFpWQw8bsuKpl1SgiZH64Q&r=I4dzGxR31OcNXCJfQzvlsiLQfucBXRucPvdrphpBsFA&m=kiLRy3Dy18TaCdFTLegz5r3LuHhd2B0eMVVxbhrJLt0&s=LLsGFzAZgTvcoyP_BY4A2BWWgGVV9e9ZAj16tjytCho&e=> . Of course, anybody can comment within the rules, but the fact that the disclosing company considers the IPR related to this I-D is public information.  

 

What is your position as WG participant and as co-author of the document? What should the WG do? 

 

Thanks and Regards,

 

Dan

I reviewed the patent that the disclosure related to - this appears to describe a method for video coding that uses loss concealment and not a method of reporting the effectiveness of loss concealment. It is of course the responsibility of the IPR holder to verify that their patent does in fact apply to the Draft/RFC to which their disclosure statement applies.  I suggest that the WG chairs ask the participants from the disclosing company to check to see if this disclosure is in fact relevant to the draft.

Alan

Hi, 

 

As you may have seen an IPR disclosure that pertains to draft-ietf-xrblock-rtcp-xr-video-lc was submitted recently. The announcement on the XRBLOCK mail list with  more information can be read at http://www.ietf.org/mail-archive/web/xrblock/current/msg01914.html <https://urldefense.proofpoint.com/v2/url?u=http-3A__www.ietf.org_mail-2Darchive_web_xrblock_current_msg01914.html&d=BQMFAg&c=BFpWQw8bsuKpl1SgiZH64Q&r=I4dzGxR31OcNXCJfQzvlsiLQfucBXRucPvdrphpBsFA&m=JT0PNFMVTwcCOwfJFWR9rPXwWO3aXrz-8hcAnDMibu4&s=Y212mtSrLAN6yGGEigFnx-qwjZv_a0r5MpWucZswumg&e=> .  
 
This I-D was on the agenda of the IESG telechat this Thursday 12/17. Our AD decided to defer this I-D to the next telechat scheduled for January 7, 2016 and asked us to confirm on the mail list that the WG still plans to proceed with the I-D. 
 
Taking into account this new information – do the participants in the WG want to proceed with the approval of this Internet-Draft? Please state your opinions on the WG mail list until Monday January 4, 2016. 
 
Thanks and Regards,
 
Dan
