Microsoft, Adobe and the Murky World of "RAND"

Open Source/Open Standards

For a week now, the IT world has been scratching its collective head over the breakdown of PDF licensing negotiations between Microsoft and Adobe.  At issue is why Adobe has allowed OpenOffice.org and Apple to bundle native support for saving documents in PDF format without any economic hooks, but apparently is requiring Microsoft to charge its customers more for Vista if this new release includes the same capabilities - even though PDF is a standard that should be available to all on the same terms.

There are, I think, two logical explanations.  One is relatively straightforward, while the other represents a convoluted and little-discussed weakness in the traditional way of creating standards.  In this entry, I'll describe both possible explanations, but I'm betting that the convoluted alternative will prove to be the explanation for what is happening here.

Let's knock off the easy explanation first, which relates to exactly what it is that Microsoft would like to license from Adobe.  At one end of the spectrum, Microsoft may only be interested in licensing those Adobe patent claims that would be infringed if Microsoft were to write software to implement the PDF specifications that have been adopted as standards by ISO/IEC.  Next up the value chain would be wanting to license the actual code that Adobe itself uses in Acrobat to save documents in the PDF format (not too likely a scenario, given that Microsoft has written a few lines of code over the years).  And finally there would be a Microsoft request to license additional features that are included in Acrobat, but which are not described in the ISO/IEC standard.  Such "proprietary extensions," as I discussed in my last blog entry, can be quite desirable - as Microsoft is well aware.

In the first case, Adobe would have an obligation to license the patent claims to Microsoft on RAND terms (on which more below).  But in the latter two cases, Adobe would be fully justified in imposing whatever unique requirements it wished on the extra code and/or patents, as the case may be, since it is not bound by the specific undertakings it entered into with AIIM  (the actual standards body that developed the PDF standard, and then submitted it to ISO/IEC) with respect to actual code or any additional functionalities.

So the first possibility is simply that Microsoft wants more than Adobe is required to give it under its standards-related undertakings.

This possibility underlines the difference between a de facto standard and a de jure standard. Broadly stated, a de facto standard describes something that the market has overwhelmingly decided that it wants to use in order to achieve the same result as an official standard (such as the interoperability that exists among users of Windows and applications that run on Windows).  Such a de facto standard can deliver a degree of interoperability that is far superior to that achieved by de jure standards, but at a cost:  with a de facto standard, everything is controlled by a single vendor (or group of vendors).

In the case of PDF, there is, in effect, a de jure standard (ISO PDF) nested within a de facto standard, which is the Adobe Acrobat product with its added features.  Another example of the same situation would be Microsoft Office, in comparison to Open XML if it is approved by Ecma and ISO/IEC.  Anyone would be free to implement Open XML (just as anyone can implement ISO PDF, whether Adobe likes it or not), but they would not be free to simply reverse engineer and sell Office (or Acrobat) in its entirety.

Now let's look at the second possibility, which is that Microsoft and Adobe are arguing about exactly what Adobe is obligated to license to Microsoft, in these specific circumstances, under a typical "RAND" licensing obligation.

RAND stands for "Reasonable And Non-Discriminatory" (in Europe, an "F," for "Fair," is often added, without really changing the meaning).  When a participant in a standards process agrees to RAND licensing, that obligation relates to any patent claims it owns that would be infringed by an implementation of the standard in question. The obligation is to provide a license to these patent claims to anyone that wants to implement the standard.  And finally, the terms offered to one implementer are required to be substantially the same as are offered to every other implementer. 

Sort of.

The reason for the "sort of" is that while the term RAND sounds fine and clear, it is in fact never strictly defined, and would be difficult to impossible to define with precision in any event.  What, for example, is "reasonable?"  Would a reasonable royalty under a standard be lower, because of the volume that will result from wide adoption of the standard, or higher, because of the value that standardization provides to the licensee?  And for non-economic terms, would requiring a license back from the implementer for any of its own infringed patent claims be reasonable? Historically, the answer to this question has been "yes" - but that was before open source licensing began to proliferate.

"Non-discriminatory" is even more difficult to nail down, for the same reason that a "most favored nation" clause in a legal contract is hard to define (and therefore enforce).   Under a most favored nations clause, a vendor (for example) agrees that if it ever gives another customer a better deal under "substantially similar circumstances," the contract will automatically readjust to give the same deal to the "most favored" customer. 

But what does that really mean?  For example, could someone under a RAND obligation (or a most favored nation clause) charge a lower royalty per unit from someone that orders 100,000 units than one that orders 1,000 (pretty clearly yes, in the most favored nation clause example)?  How about 90,000 units?  What if they both order 100,000 units, but one is an OEM and the other isn't?  Or if they are both the same, but one agrees to include mention of the vendors product in a national marketing campaign?  And how about if there is an underlying patent cross license between the vendor (or RAND patent owner) and one party, and not the other?  Could the patent owner under the RAND obligation charge the person ordering only 1,000 units no royalty at all?  In short, are any of these factual settings really "substantially similar?"

That's what I expect may be happening here, because in the real world of bundled functionalities there can be as many apples to oranges comparisons as apples to apples.  Perhaps there's an existing agreement between Microsoft and Adobe that Microsoft wants to modify at the same time, and Adobe is tying that negotiation to the PDF negotiation, attempting to take it outside its RAND obligation.  Or perhaps Adobe is saying that the Vista situation is different than the OpenOffice.org situation in some as-yet undisclosed way.  Or perhaps Adobe is saying that asking Microsoft to charge more is "reasonable" - after all, it doesn't appear that Adobe is asking that Microsoft pay anything, just that Microsoft make a bigger profit (what could be unreasonable about that?)

The reason that this represents something of a weakness in the standards system is that there's no easy way to resolve this type of situation. Standard setting organizations don't have the budget or resources to act as arbitrators to settle disputes, and therefore refuse to do so.  And the implementer never knows what kind of a deal another implementer got in any event, because the vendor has no obligation to disclose those terms or report back to the standards organization on whether or not it is meeting its RAND obligations.

This sort of dispute would easily explain two things:  how Microsoft and Adobe could have negotiated for four months over something that should have been automatic, and how Adobe could have felt safe digging in even though it is under a RAND obligation.

I'm betting on a RAND interpretation dispute as the most likely explanation of the current negotiating breakdown.  We may never find out, though, since it appears that Adobe may not be planning a complaint to the EC after all.  Late yesterday, according to ConnectIT.news, Adobe made its first statement on this topic:

"As a matter of policy we do not comment on discussions with customers, partners or competitors," stated Adobe officially in an email via its public relations company.

"However, in response to allegations made by Microsoft to the press, Adobe has made no determination to take legal action against Microsoft. Further, with regard to any discussions we have had with Microsoft about Office and Vista, our sole motivation is to maintain a fair, competitive landscape in the software industry," Adobe added.

Interestingly, I haven't been able to confirm this Adobe statement anywhere else on the Web.  But if this report is accurate, it fits the second alternative scenario perfectly.

It might be even simpler. Microsoft could have tried to pull what they tried with Kerberos: add an extension that was tied intimately to Windows and/or Office and that, in Office-generated PDFs, would be crucial to correctly processing and displaying the document, or implementing something critical (fonts, for example) in a way tied to Windows and/or Office. Adobe either said no, or said "OK, but since that's outside the ISO standard you'll need to pay a royalty per copy and you'll need to call it something other than plain PDF so users know your files aren't standard PDFs.". Microsoft, having learned from their run-in with MIT, decided to take pre-emptive action to set the tone and terms of the fight and not wait for Adobe to accuse them of trying to confuse MS-specific documents with standard PDFs.

Or maybe I'm just being paranoid.

From what I've read, it sounds like Adobe is not making patent claims, but rather threatening Microsoft with an antitrust lawsuit. That would explain why Apple and OpenOffice aren't affected.

You're right that antitrust has been reported as the basis for any complaint that Adobe might bring.  This isn't inconsistent, though, because there's nowhere to go with a RAND claim other than to sue Microsoft for implementing PDF (if they did).  In other words, they could use RAND as a basis for their right to negotiate terms, and an antitrust complaint as a club to back it up with.

Why an antitrust club?  It might well be easier and cheaper, as wel as more intimidating, for Adobe to threaten Microsoft with a complaint to the EC (which is currently evaluating how big a fine to hit Microsoft with on other grounds) than to sue Microsoft to enjoin including native PDF support in Vista.  Also, Adobe may feel that it's ability to successfully enjoin Microsoft for implementing an ISO/IEC standard might actually have no chance of success.  -  Andy

I do not think this is about IP, or licensing technology.  I do not think Adobe are asking for license revenue at all.  I think they feel their Acrobat market will be all but obliterated if MS includes "Export to PDF" as standard in MS-Office and want to try and stop them from doing so, threatening MS with monopolistic and anti-trust lawsuits if they do not.

I have written more on the subject here (excuse the blatant plug)

Not a problem on the plug; in fact, I'd already read your article and found it interesting.  The intriguing question, though, is that if Microsoft could simply implement the PDF standards as of right under Adobe's RAND undertakings, what were they negotiating over for four months?  They could just say that they would go ahead and implement, and let Adobe sue them, using the Adobe RAND undertakings as a defense.

That being said, I expect that you are right about what Adobe fears; the question is whether they have the right to withhold a RAND license to Microsoft for PDF export.  It may be that they just didn't think ahead sufficiently far to think of this when they decided to push PDF as a standard, or thought that it might have been good if it happened, and now regret the decision under current market realities.  -  Andy

I have to think Microsoft wanted to make proprietary changes to Adobe's DRM so they could tie their PDF exports to the Microsoft Sharepoint server. It would be great selling point for server sales for Microsoft - face it - Sharepoint has not been a popular product on it's own merrits. OpenOffice's and Apple's implementation are not effected because they do not use the DRM extentsions Adobe has added to pdf files in the last number of years.

I ran across a very interesting opinion that has been posted by Joe Wilcox at <a href="http://www.microsoftmonitor.com/archives/015807.html">Microsoft Monitor</a>.

One important theme I see emerging is that even an extremely permissive license like PDF fails the openess test.  RAND isn't good enough in the collaboration age.   The Internet represents a brutal state of evolution where every encumbrance is a birth defect.
